Polysorbate 65 also known as Polyoxyethylene Sorbitan Tristearate (E-436), is the "Heavyweight" of the Polysorbate family. Unlike Polysorbates 20, 60, or 80 which are monoesters - Polysorbate 65 is a tristerate, meaning -three stearic acid chains attached to polyoxyethylene sorbitan core. Triple-chain structure significantly shifts its physical properties, making it a solid or semi-solid at room temperature with a much lower HLB of 10.5. Makes it most "fat-loving" (lipophilic) member of the ethoxylated sorbitan series. Polysorbate 20 has the shortest fatty acid chain (C12) and the highest HLB value (16.7). Thus making it most water-loving member of the family, specializing in solubilisation rather than just emulsification. Source High-Purity Polysorbate 65 (CAS 9005-71-4) from Scimplify, your authoritative global manufacturer of complex sorbitan esters. Unlike standard monoesters, E-436 features a triple-stearate structure, providing a unique HLB of 10.5, ideal for stabilising complex oil-in-water emulsions where standard emulsifiers fail. Our Food-Grade Polysorbate 65 is a critical anti-crystallisation agent for the fats and oils industry, preventing 'fat bloom' in chocolates and ensuring uniform texture in non-dairy creamers. As a leading surfactant supplier, we provide a material that excels as a defoamer in industrial processing and a viscosity modifier in cosmetic creams. Scimplify ensures Global, FDA and European safety compliance, providing the thermal stability, COA/SDS transparency, and reliable bulk supply required for high-volume manufacturing

Chemical Properties & Specifications
Fat bloom inhibition in chocolate and compound coatings. By modifying the crystal growth of cocoa butter, prevents white, unappealing film that forms on stored chocolate. Acts as a high-efficiency anti-foaming agent in sugar and yeast processing
Due to its waxy consistency-Opacifying agent in shampoos and liquid soaps to give them a "pearly" or creamy appearance. In skincare, it provides a "richer" skin feel and enhanced stability for heavy night creams
Textile industry as a component of spin finishes for synthetic fibers. Provides lubrication and anti-static properties, allowing for smoother high-speed processing of yarns
Highly stable. Waxy solid, it requires heating to approximately 35°C to 45°C to transition into a pumpable liquid
Store in a cool, dry place. Avoid prolonged exposure to temperatures above 50°C to prevent discoloration
Non-hazardous. 200kg open-top drums, or 1000kg IBCs (often fitted with heating blankets)
Polysorbate 65 has a lower HLB (10.5) compared to 60 (14.9). This makes it much more effective at interacting with the vegetable fats in creamers, providing better "whiteness" and preventing the oil from separating when the creamer is added to hot, acidic coffee.
In temperate climates, Polysorbate 65 will be a solid "plug" in the drum. If your facility does not have drum heaters or a "hot room," we can provide the material in an easy-to-use flake or bead form upon request, or you may need to plan for "melting time" in your production schedule.
Yes. Because it is less water-soluble than other polysorbates, it acts as a very effective "defoamer" in aqueous systems like industrial fermentation or sugar beet processing, where it breaks surface tension and collapses foam bubbles.
The triple-chain stearate structure is actually more chemically stable against hydrolysis than the monoesters. When stored correctly, Scimplify’s Polysorbate 65 maintains its assay and acid value for at least 24 months.
