POE 20 Sorbitan Mono Laurate (Polysorbate 20)

Overview

POE 20 Sorbitan Mono Laurate, commonly known by its INCI name Polysorbate 20, is a highly versatile and widely utilized non-ionic surfactant (CAS No. 9005-64-5) derived from lauric acid and polyethoxylated sorbitan. As a polyoxyethylene (20) sorbitan monolaurate, it stands as a cornerstone excipient and additive across numerous industries, valued for its exceptional emulsifying, solubilizing, and dispersing capabilities. CanCastor’s Polysorbate 20 is meticulously manufactured to meet stringent quality benchmarks, including USP-NF, EP (European Pharmacopoeia), BP (British Pharmacopoeia), and FCC (Food Chemicals Codex) standards, ensuring its suitability for the most demanding pharmaceutical, food, and personal care applications.

Our deep expertise as an industrial chemist and global supplier ensures that CanCastor delivers a product known for its consistency, purity, and performance. Polysorbate 20's amphiphilic nature, characterized by its high HLB value (Hydrophilic-Lipophilic Balance), makes it an excellent choice for stabilizing oil-in-water emulsions, solubilizing hydrophobic substances in aqueous systems, and acting as a mild wetting agent. Its low irritancy profile and broad regulatory acceptance further cement its status as a preferred ingredient for formulators seeking reliability and efficacy.
