Science

Mechanism of Action

DIPENTAERYTHRITYL TETRABEHENATE/POLYHYDROXYSTEARATE is a complex ester, combining behenic and polyhydroxystearic fatty acids with pentaerythritol, a synthetic humectant. On the skin, it acts as an occlusive humectant, establishing a protective film that significantly reduces transepidermal water loss and contributes to a soft, smooth skin feel. Its unique composition, featuring behenic acid (a natural component of skin's sebum) and polyhydroxystearic acid (known for texture enhancement), improves the sensory profile of formulations and aids in pigment dispersion. This ingredient also adds substantivity to skincare products and enhances the stability of water-in-oil emulsions.
