Description

Glycerol Monohydroxystearate is a non-ionic surfactant and emulsifier derived from glycerin and hydroxystearic acid. This versatile compound is valued for its ability to stabilize emulsions, control viscosity, and provide a smooth, creamy texture in formulations. It is an essential ingredient for manufacturers in the cosmetics, personal care, pharmaceuticals, and food industries seeking reliable and multifunctional performance additives.

Application

• Cosmetic & Personal Care: Acts as a primary emulsifier and opacifier in creams, lotions, and makeup, providing stability and a rich, luxurious feel.
• Pharmaceuticals: Used as an excipient in topical ointments, creams, and controlled-release formulations for its emulsifying and consistency-enhancing properties.
• Food Industry: Functions as an emulsifier and stabilizer in baked goods, dairy analogs, and whipped toppings to improve texture and shelf life.
• Industrial Applications: Serves as a lubricant and anti-static agent in plastics processing and as a component in specialty coatings and polishes.
• Animal Nutrition: Employed as a pellet binder and feed emulsifier to improve feed consistency and nutrient absorption.
