Carboxydecyl Trisiloxane
What is Carboxydecyl Trisiloxane?
Carboxydecyl Trisiloxane is a synthetic organosilicon compound, specifically a modified trisiloxane featuring a carboxydecyl side chain attached to a siloxane backbone. This structure combines the volatility of short-chain silicones with a polar carboxylic group for enhanced compatibility. In cosmetics, it serves primarily as a carrier fluid and spreading agent in categories like serums, primers, and light emulsions. Its low surface tension allows rapid, even distribution across the skin, promoting uniform application of active ingredients. Upon application, it volatilizes quickly, depositing a thin, silky film without residue, which improves product texture and wear. This makes it suitable for oil-free formulations where a matte, breathable feel is desired.
Benefits
Provides a smooth, silky application feel.
Evaporates rapidly for a non-greasy finish.
