CETYL DIMETHICONE

CETYL DIMETHICONE = CETYL DIMETHICONE COPOLYOL

CAS number.: 191044-49-2

Cetyl dimethicone is a silicone polymer that functions as skin-conditioning agent.
Cetyl dimethicone is a silicone-based polymer. 
Cetyl dimethicone is alkyl modified polysiloxane.
Cetyl dimethicone is favorable over mineral oil; Cetyl dimethicone has unique spreading behavior which gives a better distribution of pigments. 

Cetyl dimethicone provides a durable velvety feel upon application to the skin and improves the shine on the skin.
Cetyl dimethicone is a silicone polymer that functions as a skin-conditioning agent or an emollient. 
Cetyl dimethicone is intended to give slip or make an application easier while also forming a protective barrier on the skin (or hair) that slows down water loss and leaves the surface soft and smooth. 

Cetyl dimethicone is used in antiperspirants, lotions, hair products, makeup, and sunscreens.
A helpful emollient ingredient that gives products a light, smooth-skin feeling.
Cetyl dimethicone is a silicone polymer that plays multiple roles in cosmetics.
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.
Dual functionality of w/o stabiliser and care agent.

Enables formulation of clear gel products.
Easy to process.
Dimethicone which is known as PDMS, Polydimethylsiloxane or dimethyl silicone fluid. 
Cetyl dimethicone can be used in a wide range of application fields.

USES and APPLICATIONS of CETYL DIMETHICONE:
-Cetyl dimethicone is used in lipsticks, eyeliners, foundations, in skin care and sun care lotions and creams.
-Cetyl dimethicone can be a foam-reducing agent, emollient, emulsifier, and occlusive (meaning it prevents water loss but does not suffocate skin).

-Cetyl dimethicone 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. 
-Anti-foaming, softening. 
-Cetyl dimethicone is a silicone polymer. 

-Conditioning agent.
-Household polishes and care agents.
-Car care eg. tar spot removers.
-Besides general industrial use, Cetyl dimethicone is also used in many skin care and beauty products.
