Polyglyceryl-2 triisostearate

Polyglyceryl-2 triisostearate (CAS 120486-24-0, formula C60H116O8) is a triester of isostearic acid and diglycerol, commercially available under trade names including Cosmol 43, Cosmol 43V, Cosmol 43N, and Nikkol DGTIS. It carries no assigned E-code and is classified within the oils, fats, and waxes category.

In personal care formulations, it functions as a lipophilic emulsifier in water-in-oil systems such as sunscreens and color cosmetics, stabilizing dispersions by reducing interfacial tension between oil and water phases. It also acts as a carrier and solvent for pigments and UV filters, improving their uniform distribution across the skin surface.

Polyglyceryl-2 triisostearate is supplied in cosmetic-grade form and falls under REACH registration requirements for the European market. Procurement teams should confirm supplier compliance documentation, including safety data sheets and certificate of analysis, prior to sourcing. Packaging formats vary by supplier and should be confirmed at the point of inquiry.
