About
A silicone-quat crosspolymer with glycidoxy (epoxide-derived) units used for hair fixing plus conditioning. Generally safe in cured form, but residual epoxide monomer is a known sensitiser, so grade-control matters.
Function
Skin benefits
- Dual fixative + conditioning action
- Durable hair film with smooth feel
- Reduces flyaways and static
Known concerns
- Glycidoxy (epoxide-derived) chemistry — residual epoxides are skin sensitizers
- Quaternary ammonium — eye irritation potential
- High-MW crosspolymer limits absorption but residual monomer is the real risk
