It can also help enhance the stability of water in oil emulsions and is touted as a pigment dispersant for color formulations. You’ll also find this ingredient in hair care, where it helps minimise frizz and contributes to a smoother comb-through. Chemically speaking, it is the triester of polyhydroxystearic acid combined with a portion of pentaerythritol (a synthetic humectant). This combination helps bind moisture and improves formulary texture. As a raw material, it is a yellow-hued liquid. Usage levels range from 0.5–5%, with amounts between 2–3% used in moisturisers and water-resistant sunscreens. Related ingredients: Polyhydroxystearic Acid
