Description

Sorbitan, Mono(2-Hydroxypropanoate) CAS NO 93980-57-5 is a non-ionic surfactant and emulsifier derived from sorbitol and lactic acid. This versatile compound is valued for its ability to stabilize emulsions and modify the surface properties of materials across diverse formulations. It is essential for manufacturers in the pharmaceutical, cosmetic, and food industries seeking reliable, high-purity ingredients for sensitive applications.

Application

• As a key emulsifier and solubilizer in topical pharmaceutical creams, ointments, and lotions.
• In cosmetic formulations for stabilizing water-in-oil (W/O) emulsions in skincare and makeup products.
• As a food-grade additive (where compliant) for emulsification in baked goods, confectionery, and dairy analogs.
• As a dispersing agent and wetting agent in industrial applications, including agrochemicals and coatings.
• In personal care products such as shampoos and conditioners for its mild surfactant properties.
• As a component in polymer and resin modification to improve compatibility and processing.
