Safety score · 0–100

Good

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

A conditioning quaternary ammonium protein derivative that helps improve hair texture and moisture retention without significant safety concerns.

A cationic silk protein hydrolysate functionalized with quaternary ammonium substituents (QUATERNIUM-79), used as an antistatic and conditioning agent in leave-on and rinse-off cosmetic formulations. The ingredient consists of protein-derived peptides with substantivity to skin and hair; no EU Annex restrictions apply, and no GHS hazard statements are assigned. Its large molecular weight and protein nature limit systemic absorption, supporting a favourable safety profile.

Skin benefits

  • Antistatic – reduces static charge in hair
  • Film-forming – improves hair smoothness and texture
  • Humectant-like moisture retention from protein hydrolysate
  • Conditions skin and hair by cationic substantivity
