About Polyhydroxystearic Acid
Polyhydroxystearic Acid is a white powder characterized by excellent dispersibility and stability; it is used in the production of sunscreens, cosmetics, food additives, and other products. As an eco-friendly compound, it is free from harmful substances and poses no risk to human health or the environment. Thanks to its favorable properties and diverse applications, Polyhydroxystearic Acid holds promising market potential across the cosmetics, pharmaceutical, and food industries.
Polyhydroxystearic Acid serves as a high-performance dispersant for inorganic pigments and titanium dioxide in color cosmetics. It significantly boosts the SPF of pigment-containing sunscreens and minimizes the "whitening effect" upon application to the skin. Even at low dosages, it markedly reduces the viscosity of dispersions, allows for higher pigment concentrations, and enhances milling efficiency.
