Cetyl Dimethicone ●
TL;DR. This ingredient functions mainly as an emollient, conditioning agent, film-former, and water-resistant feel modifier. It gives slip, gloss, and a smooth protective finish in skin care, hair care, color cosmetics, and sunscreens.
What does Cetyl Dimethicone do in a cosmetic formula?
This ingredient functions mainly as an emollient, conditioning agent, film-former, and water-resistant feel modifier. It gives slip, gloss, and a smooth protective finish in skin care, hair care, color cosmetics, and sunscreens.
Is Cetyl Dimethicone clean?
This ingredient is often flagged in clean-beauty programs because it is a synthetic organosilicon polymer with low biodegradability and film-forming residue concerns. Skin irritation is generally low, so the main friction is environmental persistence and standards eligibility rather than sensitization.
Is Cetyl Dimethicone sustainable?
This material is made through organosilicon chemistry using mineral and petrochemical inputs, so it is not a renewable-leaning choice. It is expected to be poorly biodegradable and environmentally persistent compared with common plant oils or fatty alcohols.
Is Cetyl Dimethicone COSMOS-approved?
It is not permitted under COSMOS-natural or COSMOS-organic standards. From a Green Chemistry lens, it scores weakly because it relies on nonrenewable feedstocks and has limited biodegradability, even though it is stable and typically used at low levels.
How does Cetyl Dimethicone work chemically?
The molecule is a synthetic polysiloxane modified with a long alkyl group, which lowers tack and increases cushion, spread, and water resistance. It is oil-phase soluble, broadly pH-stable, oxidation-resistant, and commonly used in low single-digit percentages depending on the desired slip, gloss, or barrier effect.
