About
A mild amphoteric surfactant and conditioning agent derived from natural fatty acids, widely used in cleansing formulations with a favourable safety profile.
Stearamidopropyl Betaine is a amphoteric surfactant derived from stearic acid and propyl betaine, used as a cleansing, foaming, and conditioning agent in rinse-off cosmetic products. It is listed in CosIng with no EU restrictions and has a well-established safety profile in cosmetic use. The compound is considered low-irritant relative to anionic surfactants, making it popular in gentle cleansers and shampoos. Minor concerns relate to trace impurities (nitrosamines) from the manufacturing process, which are managed through good manufacturing practice.
