Description

Polyethylene Glycol Monostearate CAS NO 106-11-6 is a non-ionic surfactant and emulsifier derived from polyethylene glycol and stearic acid. This versatile compound is essential for creating stable emulsions and modifying the texture and consistency of a wide range of industrial and consumer products. It is a critical ingredient for manufacturers in the cosmetics, pharmaceuticals, food processing, and plastics industries seeking reliable performance and formulation stability.

Application

• Cosmetics & Personal Care: Acts as a primary emulsifier, opacifier, and viscosity modifier in creams, lotions, ointments, and hair care products.
• Pharmaceuticals: Used as an excipient in topical formulations, ointment bases, and controlled-release drug delivery systems for its emulsifying and stabilizing properties.
• Food Industry: Functions as an emulsifier, dispersing agent, and texturizer in baked goods, dairy products, and other processed foods.
• Plastics & Polymers: Serves as an internal and external lubricant, anti-static agent, and release agent in polymer processing and manufacturing.
• Textile Processing: Employed as a softener, lubricant, and anti-static agent in fiber and fabric treatment.
• Industrial Applications: Used in metalworking fluids, paper coatings, and leather processing as an emulsifier and dispersant.
