Product Description
Polyhydroxystearic Acid is a synthetic fatty acid derivative commonly used in cosmetics and personal care products. It is derived from stearic acid through hydroxylation, resulting in a molecule with both hydrophilic and lipophilic regions. This amphiphilic structure makes it an effective emulsifier, thickener, and texture modifier, widely valued for its ability to stabilize oil-in-water or water-in-oil emulsions and improve product consistency.
Polyhydroxystearic Acid (PHSA) is a cutting-edge cosmetic ingredient renowned for its exceptional emulsifying, stabilizing, and skin-conditioning properties. As a versatile biocompatible emollient, PHSA enhances texture, improves spreadability, and boosts the longevity of creams, sunscreens, and makeup formulations. Its non-greasy, hydrating effects make it ideal for sensitive and acne-prone skin, while its oxidation resistance ensures product stability. Trusted by cosmetic chemists, Polyhydroxystearic Acid delivers superior performance in water-resistant formulations, natural cosmetics, and premium skincare.

Frequently Asked Questions
What is the primary function of Polyhydroxystearic Acid in skincare?
It primarily acts as a powerful emulsifier and dispersing agent, helping to stabilize formulations and improve the spreadability of products like sunscreens and creams.
Is this ingredient suitable for sensitive skin?
Yes, its non-greasy and hydrating properties make it suitable for various skin types, including sensitive and acne-prone skin.
How does it improve sunscreen formulations?
Polyhydroxystearic Acid acts as a sunscreen enhancer by improving the dispersion of physical filters (like Zinc Oxide) and providing water-resistant properties.
What is the recommended usage concentration?
The typical usage level ranges from 1% to 25%, depending on the desired consistency and the specific type of cosmetic product being formulated.
Is Polyhydroxystearic Acid considered a natural ingredient?
It is a synthetic derivative of stearic acid (a fatty acid), often used in natural-oriented cosmetics due to its biocompatibility and effectiveness as a plant-derived fatty acid modification.
