PEG-150 Distearate

What PEG-150 Distearate is & what it does

PEG-150 Distearate is a polyethylene glycol diester of stearic acid, made by attaching two fatty-acid chains to a long PEG backbone. Its main job in a formula is as a thickener and viscosity builder, especially in surfactant-based products like body washes, shampoos, and facial cleansers where it adds body and a richer texture. It can also act as a mild co-emulsifier. It is widely used and generally regarded as gentle in rinse-off products.
