Description

Glyceryl Monostearate CAS NO 31566-31-1 is a non-ionic surfactant and emulsifier derived from glycerol and stearic acid, widely recognized for its excellent stabilizing and texturizing properties. This versatile compound is critical for creating stable, uniform emulsions and improving the consistency and shelf-life of a vast range of consumer and industrial products. It is an essential ingredient for manufacturers in the food, pharmaceutical, and personal care industries seeking reliable performance and compliance with stringent safety standards.

Application

• Food Industry: Acts as a key emulsifier and stabilizer in baked goods, dairy products (like ice cream and whipped toppings), margarine, and confectionery to prevent ingredient separation and improve texture.
• Pharmaceuticals: Used as a lubricant, binder, and solubilizing agent in tablet and capsule formulations, and as an emulsifier in creams and ointments.
• Cosmetics & Personal Care: Serves as a primary emulsifier and opacifying agent in creams, lotions, makeup, and hair care products to provide a rich, stable consistency.
• Industrial Applications: Functions as an anti-static agent, lubricant, and processing aid in the production of plastics, textiles, and other polymer-based materials.
• Nutritional Supplements: Employed as an excipient and emulsifier in protein powders, meal replacements, and fat-soluble vitamin preparations.
