POE 20 Sorbitan Monostearate (Polysorbate 60)

Overview

POE 20 Sorbitan Monostearate, commonly known as Polysorbate 60 (CAS No. 9005-67-8, INCI: Polysorbate 60), is a highly versatile and widely used non-ionic emulsifier in a diverse range of industries. Chemically, it is the polyoxyethylene (20) sorbitan ester of stearic acid, distinguishing itself by its excellent ability to stabilize oil-in-water emulsions, solubilize lipophilic substances, and act as a dispersing agent. Our Polysorbate 60 is derived from high-quality vegetable sources, ensuring consistent performance and compliance with stringent international standards such as USP, BP, and EP monographs, as well as Kosher and Halal certifications.

At CanCastor, we leverage decades of expertise in oleochemistry to produce Polysorbate 60 with superior emulsifying power and stability. Its hydrophilic-lipophilic balance (HLB) typically falls in the range of 14.9, making it exceptionally effective in systems requiring moderate to high hydrophilicity. Our commitment to ISO 9001:2015 quality management systems ensures that every batch of Polysorbate 60 meets the exacting specifications required by our global clientele in the food, pharmaceutical, cosmetic, and industrial sectors. Through rigorous quality control and a deep understanding of surfactant chemistry, we provide a product trusted for its performance, purity, and safety.
