Description
Polyethylene Glycol Distearate (CAS 9005-08-7) is a polyethylene glycol diester of stearic acid, also known by trade designations T 4, DGD, S 95, S 200, and s1013. It carries no assigned E-code and is classified under EC 618-408-8. The compound belongs to the nonionic surfactant family within the PEG ester category.
In personal care formulations, PEG Distearate functions as an opacifier and thickener in shampoos and body washes, increasing viscosity by forming structured lamellar networks within the aqueous phase. In pharmaceutical manufacturing, it serves as an emulsifying agent and carrier in topical creams, stabilising oil-in-water systems by reducing interfacial tension between immiscible phases.
PEG Distearate is available in grades compliant with Ph.Eur. and FCC monographs, with selection determined by the degree of ethoxylation. The substance is subject to REACH registration requirements within the EU. Packaging is typically supplied in fibre drums or lined cartons suited to solid-form handling.
