Polysorbate 65

Polysorbate 65 (CAS 9005-71-4), also identified by its food additive designation E436, is a polyoxyethylene sorbitan triester derived from stearic acid.

Where is Polysorbate 65 used?

• Food production: stabilizes fat dispersions in ice cream and whipped toppings, improving texture and preventing ice crystal formation
• Cosmetics: stable oil-in-water emulsions in creams, lotions and hair conditioners
• Pharmaceuticals: carrier and solubilizer for oil-soluble active ingredients
• Home care and industrial cleaning: disperses oils and waxes into aqueous systems
• It keeps oil and water phases from separating in finished products.

Good to know: Often selected when a heavier, waxy emulsifier is preferred over lighter polysorbate grades. Technical-grade material is offered for non-regulated applications where high purity standards are not strictly required.

Commercial specifications
