Description

Polyoxyethylene Glyceryl Monostearate is a non-ionic surfactant and emulsifier derived from glycerin, stearic acid, and ethylene oxide. This versatile compound is valued for its ability to stabilize emulsions, control viscosity, and improve texture in complex formulations. It is a critical ingredient for manufacturers in the cosmetics, pharmaceuticals, and food industries seeking reliable and multifunctional excipients.

Application

• As a primary emulsifier and stabilizer in cosmetic creams, lotions, and ointments.
• Used in pharmaceutical formulations as a solubilizer and bioavailability enhancer for active ingredients.
• Functions as a dough conditioner and crumb softener in bakery and food products.
• Acts as a dispersing agent and viscosity modifier in industrial lubricants and coatings.
• Employed in the production of plasticizers and antistatic agents for polymers.
• Serves as a key component in textile auxiliaries for softening and finishing.
