In cosmetics for the face and body, silicones such as Dimethicone, Dimethiconol, Phenyl Trimethicone, Cyclomethicone, Methicone and other ingredients ending - cone.

The permissible concentration of silicones in facial cosmetics is up to 8% (in hair cosmetics - up to 20%).

Properties of silicones in cosmetics for face and body:

• Compatible with water and with many active cosmetic ingredients, effective in low concentrations, allowing you to create very stable cosmetic formulas.
• They give the skin a feeling of luxurious silkiness, dry smoothness, even out the surface of the skin, and eliminate the feeling of stickiness on the skin after applying cosmetics to it.
• They form a film on the skin that protects against UV rays and hard water.
• Protects the skin from chapping.
• They regulate foaming in shower gel, bath foam, and shaving products, giving the foam softness and durability.
• They soften the skin and help retain moisture and beneficial elements by covering it with a film.
• Facilitate the distribution of funds decorative cosmetics on the skin, lips, eyelashes.

In medicine, silicones are valued for their chemical inertness and biological compatibility with tissues human body. Silicones are included in wound care ointments. Silicones are used to make implants and blood transfusion systems, capillary and drainage tubes and much more.

Among the disadvantages of silicones are the following:

Carcinogenicity. It is assumed based on the fact that silicone breast implants in some cases provoked inflammation and tumors of the mammary glands. Studies do not confirm a direct connection between the use of silicone and malignant neoplasms, since silicone molecules are very large in size and are not able to penetrate the human body and accumulate in tissues and organs.

Comedogenicity. Silicones themselves do not clog pores, but in some cosmetics their density is quite high, and the film formed by silicones on the skin can prevent skin cleansing.

Allergies. Silicones are chemically inert and non-toxic and cannot cause a skin reaction. But silicone film can provoke increased proliferation of bacteria in the pores of the skin and cause inflammation. It is assumed that if there is any component in cosmetics to which the skin reacts with an allergy, silicone film can intensify the allergic reaction.

Skin cosmetics with silicones:

• decorative cosmetics (foundations, powders, blushes, eye shadows, mascara, lipsticks, lip glosses, etc.)
• moisturizing cream, milk, toner, emulsion for face and body
• nutritious cream For oily skin
• shaving products
• sunscreens
• bath foam

The use of cosmetics with silicones is undesirable:

• for increased skin sensitivity, tendency to allergies and acne

What are silicones used in cosmetology?

Silicones are synthetic polymers, high-molecular compounds, which initially included silicon compounds with organic groups - from methyls, ethyls or phenyls. But today the concept of “silicones” also includes inorganic compounds with silicon. The name of the group of substances comes from English word silicone(silicone), meaning "silicon".

Liquid silicone was synthesized in the early 1960s and has found applications in many fields modern life- starting with construction and ending with medicine and cosmetology. One cannot help but recall the craze for silicone implants for breast enlargement, silicone injections for changing the contours of the face and body.

Silicones have been recognized for their many beneficial properties. They are stable under strong temperature changes and resistant to deformation over a long time, as well as to hydrolysis and oxidation, are chemically neutral, have no color, taste, or smell, which makes them a valuable raw material for the production of cosmetics.

Where do silicones for cosmetics come from?

From a chemical point of view, silicones are chains of interconnected silicon and oxygen atoms, to which various organic groups are attached, attaching to the sides of the silicon atoms. Using a chemical polymerization reaction, you can change the length of the silicon-oxygen chain, connect side groups to each other, and combine several such chains with cross bonds. As a result of such reactions, new silicones with different properties are obtained, for example:

• Dimethicone, Dimethiconol And Phenyl Trimethicone- antifoam agents
• Cyclomethicone And Methicone- antistatic agents

Wherever this material is not used! It is used to produce construction sealants, breast implants, baking molds and many different cosmetic products: from foundations to deodorants and lipsticks... But won’t silicone harm us in such quantities?

Silicone is a kind of “magician”. Smooth young skin shiny hair- it instantly realizes those dreams that you would have to work tirelessly for weeks, and sometimes months, to realize if you used cosmetics with a therapeutic effect.

This “special effects master” has been used in the beauty industry for a long time. The main scientific advances that led to the creation of silicones were made in the 19th and early 20th centuries. The industrial development of this chemical began in the 40s of the last century. Silicone compounds began to be used in cosmetics in the early 50s. Now they can be found in many modern cosmetic products. Study the labels on the jars in your bathroom - and we guarantee that silicone will be found in most of them.

Reading the label
If you want to determine whether your face cream, lipstick, shampoo, or other cosmetics contain silicones, look for ingredients that end in “cone,” “conol,” or “siloxane.” The presence of these compounds is most often indicated by them. In particular, you may find:
1. With ClomethiCone - antistatic, has hygroscopic and dissolving properties, a softening effect, controls the viscosity and stickiness of various cosmetics. It is a volatile silicone: it evaporates and does not accumulate on hair or skin.
2. DimethiCone (also sometimes called silicone oil) is perhaps the most popular silicone that actively protects and softens the skin in skin care products. Provides a fairly heavy coating that is not easy to remove from hair or skin.
3. DimethiCone Cool is a water-soluble lightweight silicone that deposits in minimal quantities. Used in hair conditioners.
4. AmoDimethiCone (as well as a number of other silicones that have “amo” or “amine” in their names) are often present in products for dry, damaged hair. It holds well and, accordingly, accumulates: it is difficult to wash it out of your hair. It is better to use those products in which silicone is mentioned at the end of the list of ingredients (the closer the component is to the “top”, the more of it there is in the cosmetic product).

What role do silicones play in various cosmetics?
Silicone compounds are very diverse and can perform various functions. For example, retain moisture and color pigments, protect hair and skin from aggressive influences environment, make the product non-greasy and non-sticky... When silicone gets on a particular surface, it creates a thin, breathable film on it. And due to this, it performs one of its main functions: smoothes and gives radiance. This is why silicones are often added to hair products, makeup bases, and lip glosses. By the way, these compounds are good neighbors for other ingredients: they are non-toxic and inactive.

Foundations
Silicones promote uniform distribution of pigments.

Pomade
An important property of silicone is its ability to “grab” color pigments. Why do you think lipstick stays on your lips for several hours in a row?

Lotions, creams, gels
Here the substances are used as a thickener. They help make the cream less greasy.

Mascara
Our “hero” promotes even distribution of the product, protects eyelashes and gives them a light, healthy shine.

Shampoos and styling products
Silicones create durable, dense foam. They protect hair, significantly reduce drying time, and make hair more voluminous, soft, and silky.

Nail polishes
Due to these substances, the varnish is applied evenly, and the silicone evaporates quickly, which allows the varnish to dry faster.

Base makeup
The spherical silicone particles in the composition create a “soft focus” effect: wrinkles seem to be blurred. Plus, silicone elastomer particles absorb sebum, which gives an additional mattifying effect.

Deodorants and tanning products
Silicones prevent the appearance of white streaks and make products waterproof. And the ball in the deodorant does not “stick”.

How safe is silicone for skin, hair and the body as a whole?

Silicones, or rather, polyorganosiloxanes are a class of synthetic organosilicon compounds.

Silicones were discovered in 1901. The general formula of silicones is described by the formula n. They belong to the class of polymers with a repeating unit, i.e. It is based on an alternating bond of silicon and oxygen. A wide variety of silicones is achieved by replacing groups of organic radicals that cling to silicon. For example, in dimethicones and cyclomethicones these are methyl groups, in phenyl dimethicones these are phenyl and methyl groups.

The simultaneous presence of “organic” groups attached to the “inorganic” backbone of silicones gives the combination unique properties and allows them to be used in various industries such as aerospace, electronics (electrical insulation), medicine (excellent biocompatibility) or construction industries(weather resistance). In the cosmetics industry, polyorganosiloxanes began to be used in the 50s of the last century due to their irreplaceable properties. Linear silicones were the first to be used in cosmetics. Silicones belong to a group of raw materials that improve the properties of cosmetic products.

Silicones are obtained from silicon dioxide (quartz sand) and methanol.

Properties of silicones

They are chemically inert, non-flammable, resistant to ozone and UV rays, non-toxic, odorless, have high oxidative and thermal stability and low surface tension. Their viscosity is practically independent of temperature.

Technological advantages of silicones:

- porous and breathable, allowing the skin to produce natural secretions.
- have the ability to soften and moisturize the skin, so they can be considered effective emollients;
— used as emulsifiers (thickeners) of creams, which helps reduce the fat base in the formulation;

— promote wound healing, skin restoration from scars and scars.

— improve tactile sensations and consistency, reducing the stickiness and greasiness of cosmetics;
- visually smooth the skin;

Used in decorative cosmetics ( lipstick, deodorants, nail and hair varnishes, UV protection)
- evaporate, as a result of which their amount on the skin decreases, which contributes to the rapid drying of cosmetics on the surface of the skin.
- improve the appearance of hair, enveloping it with a thin film, which makes combing easier and adds shine, since the hair scales are smoothed and reflect light well;
- help protect hair color, make hair smoother;
- give a matte appearance to the skin;
- do not allow the presence of a white coating (white spots from antiperspirant salts) on clothing after using deodorants.

Classification of silicones

Silicones are divided into several classes depending on their properties.

1. Hydrophilic (water-soluble) silicones. Their main use is in shampoos, as they promote foaming, soften the irritating effect of surfactants and improve hair combability. Their main advantage is that they are completely washed off with water. This class includes dimethicone derivatives: dimethicone copoliol, Lauril Methicont Copolyol, PEG - 10 dimethicone, Hydroxypropyl Polysiloxane.
2. Lipophilic silicones (silicone oils). Insoluble in water. Used in masks, hair rinses. They form a surface film on the hair that is not washed off with water and smoothes the hair scales. Gives hair shine, smoothness, protects hair from damage during drying (prevents loss of moisture), hair is easy to comb. These silicones are easily washed off with special detergents. Due to their compatibility with organic emollients and waxes, lipophilic silicones are used in the formulations of decorative cosmetics: foundations, mascara, lipstick. This class includes Dimethicone, Dimethiconol, Stearyl Dimethicone.
3. Amino functional silicones. Indispensable in care products for colored hair, they enhance the depth of color of colored hair, make it easier to comb dry and wet, and improve hair condition. This class of silicones includes aminopropil Dimethicone, Trimethylsiloxamodimethicone, amodimethicone.
4. Volatile silicones. They quickly evaporate from the surface of the hair, protect hair from temperature changes (during thermal styling and during winter period). These include cyclomethicon, cyclopentasiloxane, disiloxane and phenyl thrimethicone.
5. High polymer silicones (silicone resins). They are used in professional hair cosmetics when it is necessary to create a dense film on the hair that is difficult to remove. They are used as thickeners in creams containing liquid oils, in decorative and sunscreen cosmetics. These include polyquaternium-10.

Application in cosmetics

Currently, a variety of silicones are present in almost all types of cosmetic products - hair and skin care products, hygiene products, sunscreen cosmetics and makeup products.

Safety

The CIR research team examined dimethicone and its derivatives for toxicity and allergenicity and concluded that they are safe for use in cosmetics, including Food Industry as an antifoam agent. The Food and Drug Administration (FDA, USFDA) is of the same opinion.

However, it is worth remembering that, for example, lipophilic silicones are insoluble in water and form a surface film on hair and skin, which is not washed off with water. If such silicones are improperly removed from the surface of the hair and skin, they will accumulate, interfering with the normal functioning of the physiological processes of these structures, causing itching of the scalp, hair loss and split ends, and clogging of pores. And high-polymer silicones are extremely difficult to remove even by special means, also disrupting the vital activity of the epidermis and hair shaft, which will have an extremely adverse effect on their condition.

When used correctly and the percentage of certain classes included in the formulation, silicones are not harmful, but often manufacturers are of little interest in what effect their product will have on skin and customers' hair. Therefore, lipophilic silicones can be used in products intended to be washed off only with water, and the benefit of such use is very doubtful. Moreover, from frequent use of professional hair cosmetics, decorative and sunscreen cosmetics, containing high polymer silicones, the appearance of hair and skin is significantly worsened, because the purpose of their use is the visible effect of healthy hair, as well as thick and waterproof makeup by creating a thick, indelible film. But, unfortunately, they cannot restore the structure of the core and create a healthy complexion by narrowing the pores. And no such task is set before them.

In the end, everyone makes their choice: healthy skin and hair or brief appearance of it.

5 facts about the “terrible harm” of silicones

Repetition is the mother of learning.
I already wrote about this, but questions on this topic arise on the Internet every day.

Silicones are oxygen-containing high-molecular organosilicon compounds. Their various types are used in a huge number of hair and skin care products, as well as in decorative cosmetics. Let's look at the harmful properties of silicones point by point:

Silicone is toxic and carcinogenic. There is an opinion that silicones are a poison that can harm the body by being absorbed into the blood through the skin. This is a common myth. In fact, they are a biologically and physiologically inert substance, that is, they do not enter into any reactions with living organisms. At the same time, silicones are absolutely non-toxic and are not a breeding ground for bacteria, which is why they are so widely used in medicine. Medical silicone It is precisely used for the production of skin care cosmetics.

Silicone prevents the skin from breathing. In fact, they actually create a film on the surface of the skin, hiding the pores. But at the same time, silicone molecules allow air to pass through, that is, they do not interfere with the skin’s breathing.

Silicone is a comedogenic substance. Yes, like any substance left on the surface of the skin (waxes, oils, petroleum jelly, glycerin), it can contribute to the appearance of comedones if the skin is not properly cleansed. In this case, the cause of comedones is your skin care (or lack of care), and not silicone as such.

Silicone accumulates in the hair, making it brittle. Yes, it really tends to accumulate on the surface of the hair and even the scalp. But it is not capable of making hair brittle, since it itself is elastic. The maximum harm from the accumulation of silicones is that your hair will look greasy and unwashed. Therefore, if you use hair products with silicones, you need to apply them 1-2 cm away from the hair roots, and you also need to use a deep cleansing shampoo at least once a month.

Cosmetics with silicones are absolutely useless and only give visible results. Silicones, by themselves, do not have caring properties and do not bring any benefits to hair and skin. But they are only auxiliary substances in cosmetic products. It may also contain useful vitamins, microelements, oils that provide care, moisturize and heal. Therefore, before you give up on cosmetics when you see silicone in the composition, look at where it is located and pay attention to the other ingredients. It’s also worth thinking about – what effect do you want to achieve? If it's crazy volume and shine of hair or unsurpassed durability of makeup, then silicones are simply an indispensable component. Remember - silicones in cosmetics are only auxiliary substances that do not perform any functions in themselves.

Why are silicones added to cosmetics? The fact is that they have a number of properties that simply have no analogues in total. Let's check them out!

So, silicones:
- prevent moisture loss;
- smooth the surface of the skin and hair;
- protect from external factors;
- provide uniform distribution cosmetics;
- give the products the necessary texture and consistency;
- provide durability and moisture resistance of cosmetics;
- resistant to sudden changes temperatures and UV radiation;
- add shine, elasticity and volume to the hair and matteness to the skin.

In terms of their properties, cosmetics without silicones can be identical, but it is silicones that give longevity, good texture, and provide external well-grooming when using decorative cosmetics.

Here is a short list of silicones that are most often found in cosmetics and their properties:
Dimethicone – used as an antifoaming agent and emollient;
Methicone – forms a film, smoothes the surface, antistatic;
Dimethiconol – antifoaming agent, softener;
Cyclomethicone - antistatic, also used to give the product the necessary texture and consistency;
Phenyl Trimethicone – forms a film, softens.

Why are silicones called harmful or useless?

Some household and professional cosmetic brands write about “innovative technologies” that can instantly thicken hair, mend split ends and even out skin. In fact, the whole innovation of these products lies in the silicone content. When you wash off such cosmetics, the entire visual effect disappears, and you get the feeling that things have only gotten worse. Especially silicones for hair create a temporary cosmetic effect. Naturally, the disappointment of consumers expecting immediate long-term results is growing like a snowball, reinforced by the ubiquitous propaganda about the dangers of silicone.

It’s up to you to decide whether to use silicone-containing products or not; the article dispelled myths about the irreparable harm they cause to the body. Choose your cosmetics wisely and you will achieve the best results.

Thank you! Very informative and interesting article! I'm tired of listening to opinions that silicones in creams are either miraculous or the first enemy of the skin. I am for reasonable use.

I am against silicone-containing cosmetics - why overload the skin with ballast?

I use shampoo with silicones - it adds shine and shine to my hair. Why should I give it up if, as long as I use it, my hair is great?

Have you tried treating your hair?

Girls, has no one taught human anatomy? The first and main obstacle to the rejection of cosmetics with silicones is the human skin itself, because these are molecules foreign to it!

Silicone provides only a visual cosmetic effect of smooth hair. It does not strengthen the hair at all, but, on the contrary, makes it more fragile, brittle, and dull. The silicone “capsule” prevents nutrients from penetrating the scalp and hair. This disrupts natural metabolic processes and interferes with the normal circulation of oxygen and blood. With long-term use of products containing silicone, this substance accumulates in the hair shaft. As a result, the curls, instead of their former shine, acquire a dull color, a sloppy appearance and are difficult to style. Moreover, it does not matter what kind of silicone we are talking about - they all have a harmful effect on the hair.

What are you saying? Look at the composition of silicone, what harmful effects are we talking about?

The information is very useful, but I’m just wondering, should I be careful of this silicone if it’s everywhere now?

When, for example, a makeup base is stuffed with silicone, this is quite justified (although if it is applied daily to the entire surface of the skin of the face, the question of “uselessness” arises acutely), lipstick without silicone will also be applied to the lips like plasticine, and the sensations will be the same. same. But! The same lipstick with an excess of silicone (tested and proven), firstly, will also create discomfort due to excessive “oilyness” and “slipperiness” (at the same time, most likely, it will smear with a bang), and secondly, such a lipstick really It will successfully dry out your lips - the effect of the silicone film has not been canceled. And in skincare cosmetics, in general, an excess of silicone, in my opinion, contradicts its intended purpose - skin care. After all, the cream should not only please with its application and distribution (thanks to silicones), but also perform its direct functions - moisturizing, nutrition, and so on. And excess silicone, creating a film on the skin, interferes with its natural exfoliation and cell respiration. This is where the harm of silicone lies. And here, as much as you want, you can introduce vitamins and extracts, but the effect will be significantly leveled, and silicone itself does not have a caring effect. In general, I think that a reduced silicone content in skin care cosmetics (that is, a balanced and high-quality composition, rather than a cheap composition with a “showy” effect) is much preferable.

Nonsense about the dangers of silicones is ordered by adherents of naturalness and poor people who cannot afford high-quality cosmetics with high-quality silicones.

There is nothing in silicones that would cause them harm. There is oxygen there!

Rust also contains oxygen, so smear your face with rust.

I found information about the composition of silicone on the Internet, since I was so drunk. Silicone is a polymer that consists of silicone and oxygen (-Si-O-Si-O- - and so on many times). From a chemical point of view, it is more correct to call them siloxanes or polysiloxanes. Since silicone has as many as 4 bonds, the other two are radicals various groups(methyl, ethyl, phenyl). There are compounds in nature that contain silicon. This is the well-known quartz or sand. It is formed from silicon dioxide, which can be obtained by burning silicon. Previously, it was dioxide that was used as a cleanser and as peeling for various cosmetic purposes. Silicic acids are the same dioxide, but saturated with hydrogen (or water). It is also used in cosmetology, for example, it is contained in horsetail extract and, thanks to the silicic acids in its composition, it strengthens hair, nails and skin. Unlike quartz or silicic acids, silicones are a completely synthetic compound. They are very easy to spot in the composition, since most of them have the suffix -con- in their names. In English-language literature they are often called that.

Cool! If silicones in face creams ensure their high cost, why not pour sand into the cream and smear it on? The effect is the same.

I don't use cosmetics with silicones. Creams are heavy for me, my skin doesn’t breathe, comedones appear, and my hair becomes heavy. This kind of cosmetics doesn't suit me.

I prefer cosmetics with natural ingredients.

They came up with their nonsense that silicones are harmful. The harm of silicone to hair, for example, has not been proven, but it beneficial features obvious.
Moisturizing hair. Yes, you didn't think so. If your shampoo contains silicone, it helps to moisturize your hair after you have removed the oils from it with a harsh detergent. Silicones seem to take their place, and the hair no longer feels so lonely and naked. Another thing is that instead of silicones in shampoos you can include natural oils. It will probably cost more.
They protect hair from harmful factors. This is mainly thermal exposure, but also UV radiation. The same nasty film on the hair prevents hair scales from clinging to each other and does not aggravate the problem of brittleness and split ends. Shampoo without silicones does not have such properties.
Silicones help solve some aesthetic problems: they add shine to hair, make it straighter, softer, more manageable, and sometimes even heal split ends.
Prevents split ends. After all, hair splits from not very gentle handling: combing tangled hair can cost the appearance of many double ends. If silicone helps to do this without harsh mechanical impact, the ends will breathe a sigh of relief.
Silicone is not a hair treatment. These are their improvements appearance Firstly. But don't forget that when used correctly, silicone can help prevent some hair problems.

The dangers of silicones in cosmetics are complete nonsense. They are also inert substances.

May be. But by this method of elimination, I have already realized many things about myself: I need shampoos with SLS, but no washes, mineral oil in cream is not allowed in summer and spring, in winter only at minus 25, when the skin can burst, alcohol in creams, tonics welcome. I know there is a lot more, but I have just begun to study the reaction to the most popular harmful components.

Regarding shampoos and conditioners without silicones, this is exactly what they write: the protective film is washed off and the hair begins to break, dry out, etc., but it becomes possible to treat it. Nothing breaks for me, but they look so-so. I’ve been using silicone-free ones for a long time, I started before pregnancy, it’s been more than 2 years now, but I’m not happy with the look. Although before this I had not complained about the condition of my hair - it lived wonderfully with silicones and I did not notice any increased hair loss. So I’m sitting and thinking - I want professional cosmetics with silicones - and on you - beauty. But my inner cockroach protests, I’m already used to straight women.

Actually, there is food grade silicone, you can eat it.

Do not eat, but store food products in food grade silicone products. All.

Mainly dimethicone in the composition - it is indelible. It’s possible, but after silicone the hair is so shiny. I have been using silicone-free products for a long time, but my hair, of course, is growing, but not so smooth and shiny in length. What do you use?

Silicone is good for hair! It's a bit heavy for the skin.

Hair lamination is done with silicones. So the hair is gorgeous afterwards! I agree with the author that the harm of silicones is largely far-fetched.

In general, lamination immediately gives good results, but repeated hair breaks. This is due precisely to the weight of the hair. The hair breaks off at the root - and this is not good. Is silicone the reason for this - partly yes. It ensures poor washout of lamination from hair. This is a plus for him, since the result of lamination lasts a long time, since due to weak washing out, there is a strong weighting of the hair after repeated lamination.

I have been using liquid silicone for a long time as a product against split ends. The results are great, my hair stopped splitting altogether.

Stop using liquid silicone and look at the effect. This is not an option.

In principle, silicone is not bad, but only in moderation. It provides water resistance, heat protection, shine, detangling and more. Normal professional cosmetics contains it in moderation. I can't say anything good about lamination.

[b]How do you feel about cosmetics

Sealant, sealing mass, adhesive mastic - this material can be called whatever you like. But the most popular general name for this amazing product is silicone. Due to its good adhesion (sticking) in relation to other construction and finishing materials, silicone is widely used in repair, construction, finishing and sanitary work. It is indispensable for grouting, compacting, jointing and sealing. The modern building materials market offers a huge selection of technical silicones, from the simplest and most universal, suitable for home use, to professional ones, intended for special applications.

You can call it whatever you want

Silicones are usually divided into two main groups: acetic acid and neutral. This division comes from the method of hardening of the silicone mass, which determines its properties and, accordingly, the purpose of use.

Acidic silicones are easily recognized due to the characteristic vinegar odor that is released during their use. This type of silicone sealant is extremely resistant to high temperatures and high air humidity. But acetic acid silicones have a number of disadvantages, since their composition can enter into a chemical reaction with alkaline materials, for example, with lime. Therefore, there are some restrictions in application. Acidic silicone cannot be used for cementation of mineral plasters, causes corrosion of some sensitive metals (copper), and promotes discoloration natural stone and is characterized by poor adhesion to some types of plastic.

Silicone sealants are divided into two main groups

(Illustration source: uhs-rti.ru)

Types of acidic silicones

Sanitary (plumbing) silicone is the most common type of acid-based silicone sealant. It is characterized by high resistance to moisture, fungi and mold. Most commonly used to create flexible sealing beads in kitchens, bathrooms and laundry rooms. Sanitary sealant has a high degree of adhesion to traditional sanitary surfaces (glass, ceramics, enamel surfaces, concrete, brick, wood and some types of metals). Recommended for strengthening joints between sinks and walls, ceramic pedestals, cracks around toilets, etc. Ideal for sealing gaps between walls and washbasins, bathtubs and trays. Sanitary sealant is not recommended for use on surfaces made of Teflon and natural stone. This type of silicone is also available in improved versions - glossy, or quickly hardening (within 2 hours from the moment of application).

Ideal sealant for areas with high humidity

(Illustration source: build-chemi.ru)

High-temperature silicone adhesive-sealant, as its name suggests, is particularly resistant to high temperatures (up to 285 degrees). It withstands the effects of fuel, lubricants and oils well. Has excellent adhesion to glass, ceramics and metals. It is used mainly in places that are exposed to the highest temperature conditions and require increased tightness - heating systems, air conditioners, kitchen equipment and engines.

High Temperature Silicone Sealant

Glass silicone sealant has a high degree of adhesion to smooth and porous surfaces. It is resistant to ultraviolet radiation, resistant to both low and high temperatures (from -60 to +200), has a stable color. As the name suggests, glass silicone is used primarily to create an elastic bond between glass elements, for example when glazing windows and balconies. An important point: if the frames are wooden, then they should either be painted with alkyd paints or not painted at all. This type of sealant adheres well to wood, brick, glossy surfaces and ceramic tiles, so it is often used for grouting joints. Completely unsuitable for acrylic and PVC surfaces.

Glass silicone sealant

Universal silicone sealant is designed for sealing and grouting ceramic surfaces, glass and some types of metals. Also used when working with typical porous materials (wood, concrete, brick). A universal sealant is usually used to grout the seams between ceramic tiles installed both inside and outside the building. Not recommended for use with PVC, acrylic and metals susceptible to corrosion.

Neutral silicone sealants, unlike acidic ones, do not have any foreign odors and are chemically inert to all types of building and facing materials. The only drawback of neutral silicones is big time hardening.

Types of neutral silicone sealants

Sanitary neutral sealant – resistant to external irritants. Designed for compaction and grouting of most building materials, both porous and smooth (concrete, stone, plastic, glass, ceramics, PVC, acrylic, polycarbonate, etc.). Ideal for sealing partitions, walls, windows, door frames, sealing facades and creating elastic layers. Although this type of sealant is not recommended for use in rooms with high humidity, there are improved versions of sanitary neutral silicone, which are characterized by increased resistance to moisture and a minimum curing time (up to 30 minutes from the moment of application).

Sanitary Neutral Silicone Sealant

Neutral silicone for masonry work is very resistant to weather conditions, including exposure to ultraviolet rays. This type of sealant has a high content of fungicides (chemicals that prevent the occurrence of fungi and mold). Characterized by excellent adhesion to porous surfaces without causing discoloration. Neutral silicone for masonry work is widely used for grouting and gluing natural stone (granite, marble), glass, PVC and acrylic surfaces.

Construction neutral silicone is an indispensable product for construction and repair. It is used both outdoors and indoors and has excellent adhesion properties to various building materials, including plaster and metals. Recommended for creating low-movement joints (up to 7%) in walls, window and door openings. Does not cause discoloration of materials and forms smooth surface, easy to paint.

Construction neutral silicone

Neutral silicone for mirrors is a one-component adhesive-sealant used for gluing and filling seams between mirror surfaces and creating dimensional mirror structures.

Silicone neutral sealant with increased level Hygiene, as a rule, is used in premises with special requirements for cleanliness and sterility (laboratories, hospital wards, children's rooms, catering establishments). It has an excellent degree of adhesion to various building and facing materials, and is resistant to atmospheric conditions and ultraviolet radiation. The composition is supplemented with an increased amount of antibacterial substances.

Roofing silicone sealant has good adhesion to bituminous materials, concrete, brick, ceramics, wood, metals and most types of plastic. Indispensable when carrying out various construction and repair work on the roof. It is used to create low-moving elastic joints when sealing tiles, to seal the structures of roof windows, chimneys, and connecting plates of individual roofing elements. Tolerates changes in weather conditions well.

Aquarium silicone sealant does not contain any solvents, fillers or plasticizers. Silicone adhesive sealant for glass is resistant to ultraviolet radiation, non-toxic and completely harmless to living organisms. Has increased adhesion to smooth glossy surfaces. Perfect for gluing and sealing glass containers (aquarium, terrarium, florarium), self-creation original glass decorative elements (vases, pseudo-stained glass windows), glass shelves and display cases.
