POLYSORBATE 80

Origin

Polysorbate 80 is a synthetic, plant-derived nonionic surfactant and emulsifier created by the ethoxylation of sorbitan monooleate using fatty acids typically sourced from vegetable oils such as palm or coconut oil. It is valued for its versatility, stability, and ability to solubilize essential oils and other hydrophobic ingredients in water-based formulations.

Summary

Polysorbate 80 is a highly effective solubilizer and emulsifier used to disperse essential oils, fragrances, and lipophilic actives in cosmetic and personal care products. Known for its excellent stability and mildness, it helps achieve uniform emulsions while enhancing product texture and appearance. Its ability to stabilize both oil-in-water and water-in-oil systems makes it an indispensable ingredient in lotions, creams, and cleansing formulations.
