Description

Peg-4 Distearate CAS NO 142-20-1 is a non-ionic surfactant and emulsifier derived from polyethylene glycol and stearic acid. This compound is valued for its ability to stabilize emulsions, control viscosity, and provide conditioning effects in various formulations. It is an essential ingredient for manufacturers in the personal care, cosmetics, and pharmaceutical industries seeking reliable performance in product consistency and texture.

Application

• Cosmetic & Personal Care Formulations: Acts as a primary emulsifier and opacifying agent in creams, lotions, and makeup products.
• Pharmaceutical Topicals: Used as an emulsifying base in ointments, creams, and dermatological preparations for consistent drug delivery.
• Industrial Lubricants & Textiles: Serves as a lubricant, softener, and antistatic agent in fiber processing and metalworking fluids.
• Food Processing (where compliant): Functions as an emulsifier and dispersing agent in certain food-grade industrial applications.
• Paints & Coatings: Employed as a grinding aid and pigment dispersant to improve color development and stability.
• Plastics & Polymers: Used as an internal lubricant and anti-fogging agent in polymer processing and film production.
