Description

Polyethylene Glycol Monostearate CAS NO 106-07-0 is a non-ionic surfactant and emulsifier formed by the esterification of stearic acid with polyethylene glycol. This versatile compound is valued for its ability to stabilize emulsions, modify viscosity, and act as a solubilizer and dispersing agent across numerous industrial formulations. It is an essential ingredient for manufacturers in the personal care, pharmaceutical, food processing, and industrial chemical sectors seeking reliable performance and formulation consistency.

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 drug delivery systems, including creams and ointments, for its emulsifying and stabilizing properties.
• Food Industry: Functions as an emulsifier and dispersant in food products, baked goods, and food packaging materials (where compliant with relevant regulations).
• Industrial Applications: Serves as a lubricant, anti-static agent, and processing aid in textile manufacturing, plastics, and metalworking fluids.
• Agrochemicals: Employed as a surfactant and emulsifier in pesticide and herbicide formulations to enhance spreading and adherence.
• Detergents & Cleaners: Used in industrial and institutional cleaning products for its detergent and soil-suspending capabilities.
