Dipentaerythrityl tri-polyhydroxystearate is a water-retaining emollient polymer. After application to the skin or hair, it forms a waterproof film that helps to lock in moisture. It improves the manageability of hair, such as making hair less frizzy and easier to comb. Dipentaerythrityl tri-polyhydroxystearate can also be used as a dispersing agent for pigments. Dispersing agents improve the separation of particles in a formulation and reduce settling. Dipentaerythrityl tri-polyhydroxystearate also improves SPF values when used in sunscreen products. This ingredient can be found in a variety of products, such as creams, foundation, lipsticks, hair conditioner, and sunscreen.
