What it is
Cetearyl Dimethicone is an alkyl-modified silicone in which cetearyl chains are attached to a dimethicone backbone, giving it both silicone slip and lipophilic emulsifying behavior. It functions as an emollient and helps stabilize water-in-oil emulsions, lending a smooth, non-greasy glide to creams, sticks, and color cosmetics. It appears in sunscreen and lip products where a velvety silicone feel is desired.
Safety & warnings
Considered well tolerated and non-sensitizing in typical use. Silicone alkyl emulsifiers like this are generally regarded as low irritation potential for most skin types.
Origin & sourcing
Synthetic; an alkyl-modified silicone (dimethicone) derivative.
