Dipentaerythrityl Tetrahydroxystearate/Tetraisostearate

What is Dipentaerythrityl Tetrahydroxystearate/Tetraisostearate?

Dipentaerythrityl Tetrahydroxystearate/Tetraisostearate is a complex polyester created by reacting dipentaerythritol, a polyol, with tetrahydroxystearic acid from hydrogenated castor oil derivatives and branched-chain isostearic acid from fatty acid processing. This results in a waxy, high-molecular-weight ingredient suited for anhydrous cosmetics like lipsticks, foundations, and mascaras. It functions as an emollient by forming a protective film that maintains skin hydration and suppleness while acting as a rheology modifier to increase viscosity, prevent phase separation, and ensure even pigment distribution. Its non-greasy feel supports long-wear properties and enhances product payoff without stickiness, making it ideal for color cosmetics requiring structure and creaminess.
