Sodium Beta-Sitosteryl Sulfate
What is Sodium Beta-Sitosteryl Sulfate?
Sodium Beta-Sitosteryl Sulfate is the sodium salt derived from the sulfuric ester of beta-sitosterol, a phytosterol naturally present in plants like soybeans, nuts, and avocados. These plant sterols resemble cholesterol in structure and occur widely in vegetable fats. In skincare products, it functions mainly as a skin conditioning agent, forming a lightweight barrier that helps preserve the skin's natural moisture levels and enhances tactile smoothness. It also supports emulsification in creams and lotions by stabilizing oil-water mixtures, contributing to stable, non-greasy textures. Sourced from plant materials, this ingredient provides emollient benefits ideal for daily use formulations, promoting a supple feel without heaviness.
