Polyglycerin-6

Polyglycerin-6 (CAS 36675-34-0, EC 253-154-8), also known as hexaglycerol or hexaglycerin and sold under trade names including Natrulon H-6 and PCB 06, is a polyol produced by the controlled oligomerization of glycerol to a degree of polymerization of six. It carries no assigned E-code and is classified within the alcohols and glycols category.

In personal care formulations, polyglycerin-6 functions as a humectant by binding water within the skin matrix and as an emulsifier by reducing interfacial tension between oil and water phases, improving emulsion stability. In food and pharmaceutical applications, it serves as a carrier and co-solvent, improving the solubility and dispersion of active ingredients across both aqueous and lipid systems.

Polyglycerin-6 is available in cosmetic and food-grade specifications and is subject to REACH registration requirements within the EU. Suppliers typically offer the material in drums or intermediate bulk containers, and buyers should confirm grade suitability against FCC or relevant pharmacopoeial standards for regulated applications.
