About

Hydroxystearamidopropyl Trimonium Methosulfate is a cosmetic ingredient used in product formulations. Its specific function may vary between products. Exercise caution due to limited available safety data.

Hydroxystearamidopropyl Trimonium Methosulfate is a cationic conditioning agent derived from hydroxystearic acid. Quaternary ammonium compounds (quats) are widely used in rinse-off hair care products for their antistatic and conditioning properties. The SCCS has evaluated similar quaternary ammonium ingredients as safe at typical use concentrations (up to 5%). Some individuals with sensitive skin may experience mild irritation or scalp discomfort from quat-based conditioning agents.
