SILICONE QUATERNIUM-16/GLYCIDOXY DIMETHICONE CROSSPOLYMER

65

Safety score · 0–100

Fine

Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.

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

HAIR CONDITIONINGHAIR FIXING

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
