Diethylene glycol distearate

Diethylene glycol distearate (CAS 109-30-8) is a diester formed from diethylene glycol and stearic acid, belonging to the oils, fats and waxes category. It is commonly identified by the abbreviations DEGDS and DGD, and appears in trade under names such as Witconol CAD and Diglycol Distearate. No E-code applies to this substance.

In personal care formulations, DEGDS functions as an opacifier and emulsifier in shampoos and conditioners, stabilising oil-in-water systems while contributing a pearlescent effect. In plastics processing, it acts as an internal plasticiser and lubricant, reducing polymer melt viscosity and improving surface release. Textile and leather finishing applications exploit its softening action through interaction with fibre surfaces.

DEGDS is supplied in solid or flake form and is subject to REACH registration requirements for EU market supply. Procurement teams should confirm supplier compliance documentation, including safety data sheets aligned with EU GHS standards. Packaging formats typically include fibre drums or lined sacks for bulk industrial supply.
