Description
PEG-30 Dipolyhydroxystearate (CAS 827596-80-5) is a polyethylene glycol ester of polyhydroxystearic acid, commercially available under trade names including Arlacel P 135, Arlacel 135, Rapisol B 246, and B 246. It carries no assigned E-code. The molecular formula is expressed as (C18H36O3.C2H4O)x, reflecting its polymeric ether-ester structure.
In cosmetic formulations, it functions as a water-in-oil emulsifier, stabilising sunscreen and skin care emulsions by reducing interfacial tension between aqueous and lipid phases. In pharmaceutical manufacturing, it supports the preparation of topical creams and transdermal systems where controlled droplet size and long-term emulsion stability are required. It also contributes to rheology modification by influencing the viscosity profile of the continuous phase.
PEG-30 Dipolyhydroxystearate is subject to REACH registration requirements within the EU and is used in cosmetic applications governed by EU Cosmetics Regulation 1223/2009. Suppliers typically offer it in drum and IBC formats. Buyers should confirm grade specifications and impurity profiles directly with the supplier prior to procurement.
