Description

Propylene Glycol Monostearate (Contains Ca. 35% Monopalmitate) is a non-ionic, lipophilic emulsifier and consistency agent derived from propylene glycol and stearic acid. This compound is valued for its ability to stabilize emulsions, modify texture, and improve the sensory properties of various formulations. It is an essential ingredient for manufacturers in the food, cosmetics, and pharmaceutical industries seeking reliable, high-quality excipients and additives.

Application

• Food Industry: Used as an emulsifier and stabilizer in baked goods, whipped toppings, coffee whiteners, and dairy analogs to improve texture and shelf life.
• Cosmetics & Personal Care: Acts as a co-emulsifier, opacifier, and viscosity modifier in creams, lotions, shampoos, and decorative cosmetics.
• Pharmaceuticals: Serves as an excipient in topical ointments, creams, and lotions for its emulsifying and stabilizing properties.
• Industrial Applications: Functions as a lubricant and release agent in plastic and rubber processing, and as a component in textile and paper coatings.
