Sorbitan Ester

**Sorbitan Trioleate Description** Sorbitan Trioleate is a widely used non-ionic surfactant and emulsifier derived from the esterification of sorbitan with oleic acid. It belongs to the family of sorbitan fatty acid esters and is valued for its exceptional emulsifying properties in various industries, including cosmetics, pharmaceuticals, and food. In cosmetic formulations, Sorbitan Trioleate serves as a versatile emulsifier, enabling the creation of stable oil-in-water emulsions. It facilitates the uniform dispersion of oil-based ingredients in water-based formulations, resulting in smooth textures and enhanced stability. This makes it a common ingredient in products such as creams, lotions, serums, and makeup formulations. Additionally, Sorbitan Trioleate is known for its ability to improve the solubility and bioavailability of poorly water-soluble active ingredients in pharmaceutical formulations. It is also used in the food industry as an emulsifier and stabilizer in various processed foods, including spreads, dressings, and confectionery products. Farmoganic, a reputable supplier of high-quality ingredients, offers premium-grade Sorbitan Trioleate to meet the needs of formulators in the cosmetic, pharmaceutical, and food industries. Their Sorbitan Trioleate is rigorously tested to ensure purity, stability, and efficacy, making it a reliable choice for achieving optimal results in formulations.

Sorbitan Trioleate

Sorbitan Trioleate (STO), also known as Span 85, is a non-ionic surfactant and emulsifier, typically a pale yellow viscous liquid. It's derived from sorbitol and oleic acid, and its main function is to stabilize oil-in-water and water-in-oil emulsions. STO is used in various applications, including cosmetics, pharmaceuticals, textiles, and industrial processes, where it helps with emulsification, lubrication, and as a processing aid.

Synonyms: Sorbitan Trioleate or Tween 85 CAS Number: 26266-58-0, Molecular Weight: 957.49, Chemical Formula: C60H108O8, EINECS EC Number: 247-569-3, FEMA: ----, Sorbitan Trioleate (Tween 85) is a triester of oleic acid and hexitol anhydrides derived from sorbitol. It functions as a surfactant and emulsifying agent. Sorbitan Trioleate USP NF Grade Specifications: DEFINITION Sorbitan Trioleate is the triester of Oleic Acid and Sorbitol and its mono- and dianhydrides. It yields, upon saponification, NLT 85.5% and NMT 90.0% of fatty acids, and NLT 13.0% and NMT 19.0% of polyols (w/w). IDENTIFICATION A. Sample: Residue obtained in the Assay for Fatty Acids Acceptance criteria Fats and Fixed Oils, Acid Value: 192 to 204 on 1-g sample Fats and Fixed Oils, Iodine Value: 75 to 95 B. Thin-Layer Chromatographic Identification Test: To pass the test. ASSAY Fatty Acids: Sample: 8.6 g Analysis: Transfer the Sample to a 500-mL conical flask. Cautiously add 100 mL of alcohol and 3.5 g of potassium hydroxide, then add a few glass beads, and mix. Connect a suitable condenser to the flask, reflux the mixture on a hot plate for 2 h, add 100 mL of water, and heat on a steam bath to evaporate the alcohol, adding water occasionally to replace the alcohol. Continue the evaporation until the odor of alcohol can no longer be detected, and transfer the saponification mixture, with the aid of 100 mL of hot water, to a 500-mL separator. Using extreme caution, neutralize to litmus paper with a mixture of equal volumes of sulfuric acid and water, noting the volume used, and add a 10% excess of the dilute acid. Allow the solution to cool. If salts appear, add sufficient water to produce a clear solution. Cautiously add 100 mL of solvent hexane, shake thoroughly, and withdraw the lower layer into a second 500-mL separator. Similarly extract with two more 100-mL portions of solvent hexane. Extract the combined hexane layers with 50-mL portions of water until neutral to litmus paper. Combine the extracts with the original aqueous phase to use for the Assay for Polyols. Evaporate the solvent hexane in a tared beaker on a steam bath nearly to dryness, dry under vacuum at 60C for 1 h, cool in a desiccator, and weigh the fatty acids. Acceptance criteria: 85.5% to 90.0%
