UNIEMUL PS 20 (POLYSORBATE 20)
General Information
UNIEMUL PS 20 is a non-ionic surfactant and solubilizer based on Polysorbate 20. It is derived from the esterification of sorbitol with fatty acids, typically from lauric acid, followed by ethoxylation. Widely used in cosmetic and pharmaceutical formulations, UNIEMUL PS 20 helps emulsify essential oils, fragrances, and active ingredients in aqueous solutions, providing clarity and stability.
