Potassium Polysorbate
What is Potassium Polysorbate?
Potassium Polysorbate is a synthetic potassium salt of a polysorbate compound, created by reacting sorbitan esters—derived from sorbitol, a sugar alcohol—with fatty acids and ethylene oxide. Classified as a nonionic surfactant and emulsifier, it belongs to common cosmetic additives used in formulations like cleansers, toners, and moisturizers. In products, it lowers surface tension to blend immiscible ingredients such as oils and water, forming stable emulsions that prevent separation. It also solubilizes lipophilic components like fragrances into aqueous bases, enhancing clarity and even distribution. This functionality supports gentle cleansing and improved texture in rinse-off and leave-on items, contributing to overall product efficacy without pore-clogging tendencies.
Benefits
Stabilizes emulsions for smoother, consistent product textures
