Polyhydroxystearic Acid

Description

Polyhydroxystearic acid is a multifunctional cosmetic ingredient derived from stearic acid, a naturally occurring fatty acid. This polymer serves as an effective emollient and emulsifier in various skincare and makeup formulations. Its unique structure allows it to act as a dispersing agent for mineral UV filters, enhancing the stability and efficacy of sunscreen products.

In skincare formulations, polyhydroxystearic acid helps create smooth, non-greasy textures while improving the spreadability of products. It forms a protective barrier on the skin's surface, reducing transepidermal water loss and promoting hydration. This ingredient is particularly valuable in water-resistant formulations, contributing to the longevity of sunscreens and other protective products.

Polyhydroxystearic acid is compatible with a wide range of cosmetic ingredients and is suitable for use in both oil-in-water and water-in-oil emulsions. It is generally well-tolerated by most skin types and is considered safe for use in cosmetic products. Its ability to enhance the dispersion of pigments and minerals also makes it useful in color cosmetics, improving the overall performance and wear of makeup products.
