Polyglyceryl-10 oleate

Polyglyceryl-10 oleate (CAS 79665-93-3, EC 279-230-0) is a polyglycerol ester formed by esterifying decaglycerol with oleic acid. It is sold under trade names including Decaglyn 1O, Sunsoft Q 17S, Santone 10-10, and SY-Glyster MO 750. No E-code is assigned under current EU food additive legislation.

In food and beverage manufacturing, it functions as an oil-in-water emulsifier, stabilising emulsions by reducing interfacial tension between aqueous and lipid phases. In personal care formulations it solubilises fragrance oils and lipophilic actives into water-based systems. Pharmaceutical applications include its use as a carrier and co-emulsifier in topical and oral liquid preparations.

Polyglyceryl-10 oleate is available in cosmetic and food-grade specifications and falls under REACH registration requirements for EU supply. Suppliers typically offer it in drums or intermediate bulk containers. Buyers should confirm grade suitability against FCC or relevant regional food-contact standards before procurement.
