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
