Science
Mechanism of Action
Operating primarily as an emulsifier, Sorbitan Olivate stabilizes oil-in-water emulsions by reducing interfacial tension, ensuring consistent product integrity and appearance. Its unique ability to form biomimetic liquid crystal structures closely mimics the skin's natural lipid matrix, significantly strengthening the skin barrier, optimizing hydration levels, and potentially enhancing the penetration of other active ingredients. Additionally, it imparts emollient properties, contributing to a soft skin feel, and exhibits mild surfactant qualities for gentle cleansing.

Dusting Analysis
Sorbitan Olivate is utilized in concentrations of 0.5% to 7.5% for its fundamental roles as an emulsifier, co-emulsifier, and emollient, directly contributing to product texture, stability, and skin barrier support. These usage rates are within effective therapeutic ranges, indicating it is not typically 'dusted' at low, ineffective concentrations.
