About

Stearoxypropyltrimonium Chloride is a cosmetic ingredient used in product formulations. Exercise caution due to limited available safety data.

Stearoxypropyltrimonium chloride is classified with hazard statements H302 (harmful if swallowed), H318 (causes serious eye damage), H400 (very toxic to aquatic life), and H410 (very toxic to aquatic life with long-lasting effects), earning it a Danger signal word. While permitted in the CosIng database, these hazard classifications significantly lower its safety score. In cosmetic formulations it is used as a conditioning surfactant, but environmental risk during disposal is a legitimate concern.
