POE 20 Sorbitan Mono Oleate (Polysorbate 80)

Overview

POE 20 Sorbitan Mono Oleate, commonly known as Polysorbate 80 (INCI: Polysorbate 80; CAS No.: 9005-65-6), is a highly versatile and widely utilized non-ionic emulsifier and solubilizing agent. Derived from polyethoxylated sorbitan and oleic acid (specifically, the fatty acid component often sourced from high-purity vegetable oils), it belongs to the polysorbate family, renowned for its efficacy in stabilizing diverse formulations. Its polyoxyethylene chains (typically 20 moles of ethylene oxide) impart excellent hydrophilicity, making it exceptionally effective in oil-in-water (O/W) emulsions.

At CanCastor, our extensive experience in oleochemistry ensures we deliver Polysorbate 80 with unparalleled purity and functional consistency. This ethoxylated ester is a critical workhorse in sectors ranging from pharmaceuticals and food & beverage to cosmetics and various industrial applications. Its unique chemical structure allows it to reduce interfacial tension between immiscible phases, promoting stable and homogenous mixtures where they would otherwise separate. Our commitment to expertise means we understand the intricate performance requirements of your specific application, from achieving desired dissolution rates in pharmaceutical suspensions to ensuring product stability in complex food matrices. We adhere strictly to global quality benchmarks, ensuring our product’s authoritativeness in the market.

As a global supplier, CanCastor leverages robust sourcing and manufacturing processes to guarantee the trustworthiness of our Polysorbate 80. We provide detailed certificates of analysis (COAs) and comprehensive safety data sheets (SDS) to affirm compliance with international standards such as USP/NF, BP, EP, FCC, Codex Alimentarius, and REACH. This commitment to transparency and quality assurance underpins every batch, ensuring it meets the most demanding regulatory and performance criteria.
