What Is It?
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.
Why is it used in cosmetics and personal care 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 siChinay feel. It can also help fill in fine lines/wrinkles on the face, giving it a temporary "plump" look.
