About

A plant-derived sterol sulfate that functions as a skin conditioning agent, often sourced from soybean or rapeseed, with a good safety profile in cosmetics.

Ammonium Beta-Sitosteryl Sulfate is derived from plant sterols (phytosterols) such as beta-sitosterol, which is naturally abundant in soybeans, avocados, and nuts. It functions as a skin conditioning agent and emulsifier in cosmetic formulations. Beta-sitosterol itself has a long history of safe dietary use, and the sulfated ammonium salt is considered safe for topical application at cosmetic use levels under EU Regulation 1223/2009.
