Polyglyceryl-10 dioleate

Polyglyceryl-10 dioleate (CAS 33940-99-7) is a polyglycerol ester formed by esterifying decaglycerol with two oleic acid chains. It is sold under trade names including Sunsoft Q 172Y, Salacos PG 218, Nikkol Decaglyn 2O, and Decaglycerol dioleate. It carries no assigned E-code and is classified as a nonionic surfactant.

In food and nutrition applications, it stabilises oil-in-water emulsions by orienting at the oil-water interface, reducing interfacial tension and preventing droplet coalescence. In personal care formulations, it functions as a carrier and co-emulsifier in anhydrous systems, improving the spreadability and skin deposition of active ingredients. Pharmaceutical manufacturers use it to solubilise lipophilic actives in oral and topical delivery systems.

Polyglyceryl-10 dioleate is available in cosmetic and food-grade forms and is subject to REACH registration requirements within the EU. Suppliers typically offer it in drums or intermediate bulk containers. Buyers should confirm grade-specific compliance documentation, including safety data sheets and certificates of analysis, prior to procurement.
