Full Description

Cetyl methicone is an alkyl-modified silicone (a cetyl-substituted polydimethylsiloxane). It is used as an emollient and conditioning agent in cosmetic and personal-care formulations, where it provides a silky, water-repellent film.

Frequently Asked Questions

Is methicone the same as dimethicone?

No. They are related silicones but structurally distinct: dimethicone is polydimethylsiloxane, while methicone-type silicones carry methyl-hydrogen siloxane units. Cetyl methicone is an alkyl-modified silicone (a cetyl-substituted polydimethylsiloxane), different again. They are separate INCI materials.

What is cetyl methicone used for?

Cetyl methicone is an alkyl-modified silicone used as an emollient and conditioning agent in cosmetic and personal-care formulations. It imparts a silky, water-repellent, long-wearing film. RawSource supplies it in bulk for formulators.

What is cetyl methicone?

It is a cetyl (C16 alkyl)-substituted polydimethylsiloxane, i.e., a silicone whose backbone is modified with long-chain alkyl groups. This structure gives it both silicone slip and emollient, hydrophobic film-forming behavior in personal-care systems.

Is cetyl methicone soluble in water?

As an alkyl-modified silicone it is hydrophobic and not water-soluble; it is oil/silicone-phase soluble and imparts a water-repellent film. Formulate it into the oil or silicone phase. Confirm specifics against the technical data sheet for your grade.

What documentation and packaging does RawSource provide for cetyl methicone?

It typically ships as a fluid in pails, drums, or totes depending on volume, with HS classification generally under 391000 (silicones in primary forms). A CoA and SDS accompany each lot. Submit a bulk RFQ for current pricing.
