Polydimethylsiloxane (PDMS) DIMETHICONE 100 ( DMETKON 100 ), also known as dimethylpolysiloxane or dimethicone, belongs to a group of polymeric organosilicon compounds that are commonly referred to as silicones.[1] PDMS is the most widely used silicon-based organic polymer due to its versatility and properties leading to a manifold of applications.[2] It is particularly known for its unusual rheological (or flow) properties. PDMS is optically clear and, in general, inert, non-toxic, and non-flammable. It is one of several types of silicone oil (polymerized siloxane). Its applications range from contact lenses and medical devices to elastomers; it is also present in shampoos (as it makes hair shiny and slippery), food (antifoaming agent), caulking, lubricants and heat-resistant tiles.

DIMETHICONE 100 ( DMETKON 100 ) Structure

The chemical formula for PDMS DIMETHICONE 100 ( DMETKON 100 ) is CH3[Si(CH3)2O]nSi(CH3)3, where n is the number of repeating monomer [SiO(CH3)2] units.[3] Industrial synthesis can begin from dimethyldichlorosilane and water by the following net reaction:

{displaystyle n{ce {Si(CH3)2Cl2}}+(n+1){ce {H2O->HO[-Si(CH3)2O-]_{mathit {n}}H}}+2n{ce {HCl}}}{displaystyle n{ce {Si(CH3)2Cl2}}+(n+1){ce {H2O->HO[-Si(CH3)2O-]_{mathit {n}}H}}+2n{ce {HCl}}}

The polymerization reaction evolves hydrochloric acid. For medical and domestic applications, a process was developed in which the chlorine atoms in the silane precursor were replaced with acetate groups. In this case, the polymerization produces acetic acid, which is less chemically aggressive than HCl. As a side-effect, the curing process is also much slower in this case. The acetate is used in consumer applications, such as silicone caulk and adhesives.

DIMETHICONE 100 ( DMETKON 100 ) Branching and capping

Hydrolysis of Si(CH3)2Cl2 generates a polymer that is terminated with silanol groups (−Si(CH3)2OH]). These reactive centers are typically “capped” by reaction with trimethylsilyl chloride:

2 Si(CH3)3Cl + [Si(CH3)2O]n−2[Si(CH3)2OH]2 → [Si(CH3)2O]n−2[Si(CH3)2O Si(CH3)3]2 + 2 HCl

Silane precursors with more acid-forming groups and fewer methyl groups, such as methyltrichlorosilane, can be used to introduce branches or cross-links in the polymer chain. Under ideal conditions, each molecule of such a compound becomes a branch point. This can be used to produce hard silicone resins. In a similar manner, precursors with three methyl groups can be used to limit molecular weight, since each such molecule has only one reactive site and so forms the end of a siloxane chain.

Well-defined PDMS DIMETHICONE 100 ( DMETKON 100 ) with a low polydispersity index and high homogeneity is produced by controlled anionic ring-opening polymerization of hexamethylcyclotrisiloxane. Using this methodology it is possible to synthesize linear block copolymers, heteroarm star-shaped block copolymers and many other macromolecular architectures.

The polymer is manufactured in multiple viscosities, ranging from a thin pourable liquid (when n is very low), to a thick rubbery semi-solid (when n is very high). PDMS molecules have quite flexible polymer backbones (or chains) due to their siloxane linkages, which are analogous to the ether linkages used to impart rubberiness to polyurethanes. Such flexible chains become loosely entangled when molecular weight is high, which results in PDMS’ unusually high level of viscoelasticity.

DIMETHICONE 100 ( DMETKON 100 ) Mechanical properties

PDMS is viscoelastic, meaning that at long flow times (or high temperatures), it acts like a viscous liquid, similar to honey. However, at short flow times (or low temperatures), it acts like an elastic solid, similar to rubber. Viscoelasticity is a form of nonlinear elasticity that is common amongst noncrystalline polymers.[4] The loading and unloading of a stress-strain curve for PDMS do not coincide; rather, the amount of stress will vary based on the degree of strain, and the general rule is that increasing strain will result in greater stiffness. When the load itself is removed, the strain is slowly recovered (rather than instantaneously). This time-dependent elastic deformation results from the long-chains of the polymer. But the process that is described above is only relevant when cross-linking is present; when it is not, the polymer PDMS cannot shift back to the original state even when the load is removed, resulting in a permanent deformation. However, permanent deformation is rarely seen in PDMS, since it is almost always cured with a cross-linking agent.  

If some PDMS DIMETHICONE 100 ( DMETKON 100 ) is left on a surface overnight (long flow time), it will flow to cover the surface and mold to any surface imperfections. However, if the same PDMS is poured into a spherical mold and allowed to cure (short flow time), it will bounce like a rubber ball.[3] The mechanical properties of PDMS enable this polymer to conform to a diverse variety of surfaces. Since these properties are affected by a variety of factors, this unique polymer is relatively easy to tune. This enables PDMS to become a good substrate that can easily be integrated into a variety of microfluidic and microelectromechanical systems.[5][6] Specifically, the determination of mechanical properties can be decided before PDMS is cured; the uncured version allows the user to capitalize on myriad opportunities for achieving a desirable elastomer. Generally, the cross-linked cured version of PDMS resembles rubber in a solidified form. It is widely known to be easily stretched, bent, compressed in all directions.[7] Depending on the application and field, the user is able to tune the properties based on what is demanded.

Overall PDMS DIMETHICONE 100 ( DMETKON 100 )has a low elastic modulus which enables it to be easily deformed and results in the behavior of a rubber.[8][9][10] Viscoelastic properties of PDMS can be more precisely measured using dynamic mechanical analysis. This method requires determination of the material’s flow characteristics over a wide range of temperatures, flow rates, and deformations. Because of PDMS’s chemical stability, it is often used as a calibration fluid for this type of experiment.

The shear modulus of PDMS DIMETHICONE 100 ( DMETKON 100 ) varies with preparation conditions, and consequently dramatically varies in the range of 100 kPa to 3 MPa. The loss tangent is very low (tan δ ≪ 0.001).[10]

DIMETHICONE 100 ( DMETKON 100 ) Chemical compatibility

PDMS DIMETHICONE 100 ( DMETKON 100 ) is hydrophobic.[6] Plasma oxidation can be used to alter the surface chemistry, adding silanol (SiOH) groups to the surface. Atmospheric air plasma and argon plasma will work for this application. This treatment renders the PDMS surface hydrophilic, allowing water to wet it. The oxidized surface can be further functionalized by reaction with trichlorosilanes. After a certain amount of time, recovery of the surface’s hydrophobicity is inevitable, regardless of whether the surrounding medium is vacuum, air, or water; the oxidized surface is stable in air for about 30 minutes.[11] Alternatively, for applications where long-term hydrophilicity is a requirement, techniques such as hydrophilic polymer grafting, surface nanostructuring, and dynamic surface modification with embedded surfactants can be of use. [12]

Solid PDMS DIMETHICONE 100 ( DMETKON 100 ) samples (whether surface-oxidized or not) will not allow aqueous solvents to infiltrate and swell the material. Thus PDMS structures can be used in combination with water and alcohol solvents without material deformation. However most organic solvents will diffuse into the material and cause it to swell.[6] Despite this, some organic solvents lead to sufficiently small swelling that they can be used with PDMS, for instance within the channels of PDMS microfluidic devices. The swelling ratio is roughly inversely related to the solubility parameter of the solvent. Diisopropylamine swells PDMS to the greatest extent; solvents such as chloroform, ether, and THF swell the material to a large extent. Solvents such as acetone, 1-propanol, and pyridine swell the material to a small extent. Alcohols and polar solvents such as methanol, glycerol and water do not swell the material appreciably.[13]

DIMETHICONE 100 ( DMETKON 100 ) Applications

Surfactants and antifoaming agents

PDMS DIMETHICONE 100 ( DMETKON 100 ) is a common surfactant and is a component of defoamers.[14] PDMS, in a modified form, is used as an herbicide penetrant[15] and is a critical ingredient in water-repelling coatings, such as Rain-X.[16]

DIMETHICONE 100 ( DMETKON 100 ) Hydraulic fluids and related applications

DIMETHICONE 100 ( DMETKON 100 ) is also the active silicone fluid in automotive viscous limited slip differentials and couplings. This is usually a non-serviceable OEM component but can be replaced with mixed performance results due to variances in effectiveness caused by refill weights or non-standard pressurizations.[citation needed]

DIMETHICONE 100 ( DMETKON 100 ) Soft lithography

PDMS  DIMETHICONE 100 ( DMETKON 100 )is commonly used as a stamp resin in the procedure of soft lithography, making it one of the most common materials used for flow delivery in microfluidics chips.[17] The process of soft lithography consists of creating an elastic stamp, which enables the transfer of patterns of only a few nanometers in size onto glass, silicon or polymer surfaces. With this type of technique, it is possible to produce devices that can be used in the areas of optic telecommunications or biomedical research. The stamp is produced from the normal techniques of photolithography or electron-beam lithography. The resolution depends on the mask used and can reach 6 nm.[18]

In biomedical (or biological) microelectromechanical systems (bio-MEMS), soft lithography is used extensively for microfluidics in both organic and inorganic contexts. Silicon wafers are used to design channels, and PDMS is then poured over these wafers and left to harden. When removed, even the smallest of details is left imprinted in the PDMS. With this particular PDMS block, hydrophilic surface modification is conducted using plasma etching techniques. Plasma treatment disrupts surface silicon-oxygen bonds, and a plasma-treated glass slide is usually placed on the activated side of the PDMS (the plasma-treated, now hydrophilic side with imprints). Once activation wears off and bonds begin to reform, silicon-oxygen bonds are formed between the surface atoms of the glass and the surface atoms of the PDMS, and the slide becomes permanently sealed to the PDMS, thus creating a waterproof channel. With these devices, researchers can utilize various surface chemistry techniques for different functions creating unique lab-on-a-chip devices for rapid parallel testing.[5] PDMS can be cross-linked into networks and is a commonly used system for studying the elasticity of polymer networks.[citation needed] PDMS can be directly patterned by surface-charge lithography.[19]

PDMS DIMETHICONE 100 ( DMETKON 100 ) is being used in the making of synthetic gecko adhesion dry adhesive materials, to date only in laboratory test quantities.[20]

Some flexible electronics researchers use PDMS DIMETHICONE 100 ( DMETKON 100 ) because of its low cost, easy fabrication, flexibility, and optical transparency.[21]

DIMETHICONE 100 ( DMETKON 100 ) Stereo lithography

In stereo lithography (SLA) 3D printing, light is projected onto photocuring resin to selectively cure it. Some types of SLA printer are cured from the bottom of the tank of resin and therefore require the growing model to be peeled away from the base in order for each printed layer to be supplied with a fresh film of uncured resin. A PDMS layer at the bottom of the tank assists this process by absorbing oxygen : the presence of oxygen adjacent to the resin prevents it adhering to the PDMS, and the optically clear PDMS permits the projected image to pass through to the resin undistorted.

DIMETHICONE 100 ( DMETKON 100 ) Medicine and cosmetics

Activated DIMETHICONE 100 ( DMETKON 100 ), a mixture of polydimethylsiloxanes and silicon dioxide (sometimes called simethicone), is often used in over-the-counter drugs as an antifoaming agent and carminative.[22][23] It has also been at least proposed for use in contact lenses.[24]

Silicone breast implants are made out of a PDMS DIMETHICONE 100 ( DMETKON 100 ) elastomer shell, to which fumed amorphous silica is added, encasing PDMS gel or saline solution. [25]

In addition, PDMS DIMETHICONE 100 ( DMETKON 100 ) is useful as a lice or flea treatment because of its ability to trap insects.[26] It also works as a moisturizer that is lighter and more breathable than typical oils.

DIMETHICONE 100 ( DMETKON 100 ) Skin

PDMS DIMETHICONE 100 ( DMETKON 100 ) is used variously in the cosmetic and consumer product industry as well. For example, PDMS can be used in the treatment of head lice on the scalp[26] and dimethicone is used widely in skin-moisturizing lotions where it is listed as an active ingredient whose purpose is “skin protection.” Some cosmetic formulations use dimethicone and related siloxane polymers in concentrations of use up to 15%. The Cosmetic Ingredient Review’s (CIR) Expert Panel, has concluded that dimethicone and related polymers are “safe as used in cosmetic formulations.”[27]

DIMETHICONE 100 ( DMETKON 100 ) Hair

PDMS DIMETHICONE 100 ( DMETKON 100 ) compounds such as amodimethicone, are effective conditioners when formulated to consist of small particles and be soluble in water or alcohol/act as surfactants[28][29] (especially for damaged hair[30]), and are even more conditioning to the hair than common dimethicone and/or dimethicone copolyols.[31]

DIMETHICONE 100 ( DMETKON 100 ) Flea treatment for pets

Dimethicone DIMETHICONE 100 ( DMETKON 100 ) is the active ingredient in a liquid applied to the back of the neck of a cat or dog from a small one time use dose disposable pipette. The parasite becomes trapped and immoblised in the substance and thus breaks the life cycle of the insect.

DIMETHICONE 100 ( DMETKON 100 ) Foods

PDMS DIMETHICONE 100 ( DMETKON 100 ) is added to many cooking oils (as an antifoaming agent) to prevent oil splatter during the cooking process. As a result of this, PDMS can be found in trace quantities in many fast food items such as McDonald’s Chicken McNuggets, french fries, hash browns, milkshakes and smoothies[32] and Wendy’s french fries.[33]

Under European food additive regulations, it is listed as E900.

DIMETHICONE 100 ( DMETKON 100 ) Condom lubricant

PDMS DIMETHICONE 100 ( DMETKON 100 ) is widely used as a condom lubricant.[34][35]

DIMETHICONE 100 ( DMETKON 100 ) Domestic and niche uses

Many people are indirectly familiar with PDMS DIMETHICONE 100 ( DMETKON 100 ) because it is an important component in Silly Putty, to which PDMS imparts its characteristic viscoelastic properties.[36] Another toy PDMS is used in is Kinetic Sand. The rubbery, vinegary-smelling silicone caulks, adhesives, and aquarium sealants are also well-known. PDMS is also used as a component in silicone grease and other silicone based lubricants, as well as in defoaming agents, mold release agents, damping fluids, heat transfer fluids, polishes, cosmetics, hair conditioners and other applications. PDMS has also been used as a filler fluid in breast implants.

It can be used as a sorbent for the analysis of headspace (dissolved gas analysis) of food.[37]

DIMETHICONE 100 ( DMETKON 100 ) Safety and environmental considerations

According to Ullmann’s Encyclopedia, no “marked harmful effects on organisms in the environment” have been noted for siloxanes. PDMS is nonbiodegradable, but is absorbed in waste water treatment facilities. Its degradation is catalyzed by various clays.[38]

DIMETHICONE 100 ( DMETKON 100 ) is a silicone oil that is also known as polydimethylsiloxane (PDMS). It has viscoelastic properties. Dimethicone is used as a surfactant, antifoaming agent, carminative in various products such as medical devices, food products, and lubricants. It is used in a number of health and beauty products including hair care products such as shampoo, conditioner, leave-in conditioner, and de-tangling products. On skin, it is also observed to have moisturizing actions 6,8.

A study found that that the 100 % DIMETHICONE 100 ( DMETKON 100 ) product is a safe and highly effective head lice treatment for children and may serve as less toxic and less resistance-prone alternative to pesticide-containing products.

Discover what dimethicone is, how it’s used, and why it’s more harmful than you might think.As an eco-friendly skincare brand, Puracy wants to set the record straight about what dimethicone is – and why we never use it in our products.If you’ve ever used a makeup primer with a silky or slippery feel, it probably had some version of dimethicone (polydimethylsiloxane) in it. Because molecules of this silicone-based polymer are too large for the skin and hair to absorb, these products leave behind a thin layer. As a result, you get shinier-looking and smoother-feeling skin and hair – a major reason for the popularity of dimethicone in cosmetics.Board-certified dermatologist Dr. Julie Jackson states that dimethicone “does not interact with the stratum corneum (the top layer of the skin). It works by forming a film that prevents the loss of water through the skin, thus keeping the skin moisturized. It also works as an emollient, filling the spaces between cracks in the skin.”There are hundreds of dimethicone uses in personal care products, with the most popular being diaper rash cream, moisturizer, hand lotion, and liquid foundation. This ingredient allows products to be applied seamlessly. In makeup primers, it prevents foundation from changing colors and cracking.Most hair care companies use dimethicone and silicone to coat the hair cuticle and make detangling easier. A lot of this comes down to these ingredients’ affordability and effectiveness. There are simply very few eco-friendly, dimethicone-free products that can provide the same results.After years of research and development with expert chemists and testers, Puracy Natural Shampoo and Conditioner are rare examples of dimethicone-free hair products that manage to leave all hair types moisturized, bouncy, and shiny.Puracy is proud to be one of the first companies to use this 100% sustainable and biodegradable emollient, which seamlessly replicates the effects of both dimethicone and silicone. When pressed on whether dimethicone can clog pores and lead to acne, Dr. Jackson concluded, “There is no evidence that dimethicone can cause acne.”Even though it’s an unnatural, man-made substance, Dr. Jackson agrees that dimethicone is a good chemically-inert moisturizer. But it isn’t biodegradable – and the current environmental research isn’t positive. As a result, we’ll never include it in any Puracy formulas.The first step to avoiding dimethicone is by carefully reading labels and looking for products that pledge to use biodegradable, renewable ingredients. Next, choose items that are dimethicone, silicone-, and sulfate-free – like every Puracy personal care product.Dimethicone (also known as polydimethylsiloxane) – a silicon-based polymer – is a man-made synthetic molecule comprised of repeating units called monomers. Silicon is the second most abundant element in the Earth’s crust (after oxygen). Dimethicone is one of the most widely used ingredients in cosmetics and personal care products and can also be found in many cooking oils, processed foods, and fast food items.According to 2019 data in U.S. FDA’s Voluntary Cosmetic Registration Program (VCRP), dimethicone was reported to be used in 12,934 products. This included products for use near the eye, shampoos and conditioners, hair dyes and colors, bath oils, skin care products, bath soaps and detergents, suntan preparations and baby products.Dimethicone works as an anti-foaming agent, skin protectant, skin conditioning agent, and hair conditioning agent. It prevents water loss by forming a barrier on the skin. Like most silicone materials, dimethicone has a unique fluidity that makes it easily spreadable and, when applied to the skin, gives products a smooth and silky feel. It can also help fill in fine lines/wrinkles on the face, giving it a temporary “plump” look.Dimethicone is an important component in several toys, including Silly Putty, to which it imparts its unique viscosity and elastic properties, and Kinetic Sand, which mimics the physical properties of wet sand and can be molded and shaped into any desired form. Dimethicone is also a critical ingredient in rubbery silicone caulks, adhesives, and aquarium sealants, as well as water-repelling coatings, such as Rain-X.f you were to ask your friends, “What is dimethicone?” you’d likely get a lot of blank stares. Buuut I’m also willing to bet you’d hear some very, very opinionated responses (if, you know, your friends happen to be beauty editors). Silicones (like dimethicone) in cosmetics is a controversial topic, and for every person who loves them and swears by their silicone-based makeup primer, there’s another person who actively avoids all silicones in skincare, haircare, and makeup.So what’s the deal? Is dimethicone okay to use, or do you need to overhaul your medicine cabinet? Welp, allow me to present you with the facts and expert insights from a dermatologist and trichologist about using dimethicone in your skincare and hair products so that you can make that decision for yourself. Because, spoiler, it really is a you decision in the end.Dimethicone is a silicon-based polymer that, when used in beauty products, gives the formula an incredibly smooth, velvety, slippery feel that you either love or hate (although I’ll never understand the people who hate it TBH. I freakin’ love the smooth feeling of silicones).But dimethicone is not only used for its sensory properties—it also helps to temporarily smooth fine lines and wrinkles, functions as an emollient (aka a skin-conditioning agent), and also has some occlusive properties (meaning it prevents water loss by creating a seal or a barrier on your skin). And because of these properties, you’ll usually find dimethicone in your foundations, makeup primers, hair products, moisturizers, etc. Basically, unless a label specifically says it’s silicone-free, you can almost guarantee it’s in ev-ery-thing.Despite what the haters may say, according to the Cosmetic Ingredient Review Panel, dimethicone is safe when used in cosmetic products. What’s more, the CIR Expert Panel also says because of the large molecular weight of dimethicone, it’s unlikely that it can be absorbed into the skin in a significant way. Board-certified dermatologist Dhaval G. Bhanusali, MD, isn’t concerned either: “I think, all too often, people put things in categories and say, ‘all of this is bad,'” he says. “But in this case, I don’t know of many colleagues who are concerned with dimethicone in skincare products.”Although dimethicone is fine for use on the skin, things get a little trickier when using it on your hair, mainly because it can coat your strands and weigh them down (which is not great for curls or fine hair). But, “if you have dry, damaged hair that’s prone to tangles, dimethicone can help create that sleek, slippery feel, making detangling easy and giving the appearance that the hair is super-conditioned and healthy,” says trichologist and creator of Colour Collective, Kerry E. Yates. “Dimethicone is also heavily used in styling products to help ‘glue’ the cuticles down to create that smooth, shiny effect in hair.”In short, yes. The reason why you might experience dry hair from using a dimethicone-based formula is that the product builds up, which prevents the hair from achieving a proper moisture balance. This is why excess use of dimethicone can result in dry, brittle ends that are prone to breakage.Just because the experts say dimethicone is not the enemy the internet has made it out to be, it doesn’t mean you have to use it. Dimethicone has its pros and cons, so if you’ve read the above and decided you still don’t want to use it, don’t! No one’s making you! The beauty of an oversaturated beauty market is that you have tons of silicone-free options to use instead, like the below:Dimethicone in its simplest form is polydimethylsiloxane, also known as silicone oil, but more commonly called dimethicone. Silicone oils are derived from silica (sand and quartz are silicas).Dimethicone comes in various viscosities, this one is 350 centistokes, a medium viscosity which offers excellent barrier properties when used in skin protectant formulations. It adds slip and glide, reducing tackiness. It offers conditioning properties when used in hair and skin care applications.Used at a rate of 1% to 30%, dimethicone conforms to the FDA’s Tentative Final Monograph on OTC Skin Protectants. However, provided you make no drug claims for it, dimethicone does not have to be declared as an active ingredient, nor does your product or facility need to conform to OTC drug production standards. Dimethicone can be added to any cosmetic and declared on the ingredient label in descending order. When using dimethicone in cosmetic formulations, one should be guided by the usage rates in the Cosmetic Ingredient Review (CIR) tables (see our Reference Room for links to these PDFs) as these apply to cosmetics rather than OTC products.The CIR lists Dimethicone in the Cosmetic Ingredients Found Safe as Used in the following amounts,Dimethicone is promoted as a defoaming agent for relief of abdominal pain due to retained gas and for “colic” in infants. It has been suggested that it may provide mucosal protection3 and it is included in many combined antacid preparations. It is also used to improve visibility during endoscopy. This article reviews the actions and clinical uses of dimethicone.Dimethicone (also known as polydimethylsiloxane or PDMS) is technically called a silicone-based polymer. More simply, it’s a silicone oil with certain properties that make it extremely popular in today’s personal care properties.In hair care products, dimethicone is used to provide smoothness, particularly in conditioners and detanglers, where the ingredient helps smooth hair and provide better comb-through. Because dimethicone leaves a sort of covering on the hair strands, it can also make hair appear shinier.In accordance with CIR Procedures, because it has been at least 15 years since the original safety assessment was published, the Panel should consider whether the safety assessment of Stearoxy Dimethicone, Dimethicone, Methicone,Amino Bispropyl Dimethicone,Aminopropyl Dimethicone, Amodimethicone, Amodimethicone Hydroxystearate,Behenoxy Dimethicone, C24-28 Alkyl Methicone, C30-45 Alkyl Methicone, C30-45 Alkyl Dimethicone, Cetearyl,Methicone, Cetyl Dimethicone, Dimethoxysilyl Ethylenediaminopropyl Dimethicone, Hexyl Methicone,Hydroxypropyldimethicone, Stearamidopropyl Dimethicone, Stearyl Dimethicone, Stearyl Methicone, and Vinyl Dimethicone should be re-opened. An exhaustive search of the world’s literature was performed for studies dated 1998 forward. A synopsis of the relevant new data is enclosed Stearoxy Dimethicone, Dimethicone, Methicone, Amino Bispropyl Dimethicone,Aminopropyl Dimethicone, Amodimethicone, Amodimethicone Hydroxystearate,Behenoxy Dimethicone, C24-28 Alkyl Methicone, C30-45 Alkyl Dimethicone,C30-45 Alkyl Methicone, Cetearyl Methicone, Cetyl Dimethicone, Dimethoxysilyl,Ethylenediaminopropyl Dimethicone, Hexyl Methicone, Hydroxypropyldimethicone,Stearamidopropyl Dimethicone, Stearyl Dimethicone, Stearyl Methicone, and Vinyldimethicone. Dimethicone and mineral spirits from the CIR report. He noted that the necrosis observed was due to the mineral spirits, and not Dimethicone. The Panel voted unanimously in favor of issuing a Final Report with a safe as used conclusion on the Stearoxy Dimethicone ingredient family. Dimethicone has been used as a physical barrier method of eradicating head lice and eggs. 3,4 Dimethicone use is also prevalent in condom lubricants5, and, it is used industrially in various construction sealants, rubber, and paints, and is taken orally as an anti-flatulence agent.6
