Description

Propylene Glycol Monostearate is a non-ionic, food-grade emulsifier and stabilizer derived from propylene glycol and stearic acid. This versatile compound is essential for creating and maintaining consistent textures, preventing ingredient separation, and improving mouthfeel in a wide range of formulations. It is a critical ingredient for manufacturers in the food, cosmetics, and pharmaceutical industries seeking reliable performance and regulatory compliance.

Application

• Food Industry: Acts as an emulsifier in baked goods, whipped toppings, coffee whiteners, and dairy analogs to ensure smooth texture and extended shelf life.
• Cosmetics & Personal Care: Used as a opacifier, thickener, and emollient in creams, lotions, shampoos, and deodorants to provide a rich, stable consistency.
• Pharmaceuticals: Serves as a lubricant and binder in tablet formulations and as an emulsifying agent in topical ointments and creams.
• Industrial Applications: Functions as a lubricant and anti-static agent in plastics processing and as a component in textile and paper coatings.
