Distearyl Phthalic Acid Amide
What is Distearyl Phthalic Acid Amide?
Distearyl Phthalic Acid Amide is a synthetic waxy compound formed by reacting phthalic acid with stearylamine, resulting in a lipid-like diamide structure with two long-chain C18 alkyl groups. Primarily used in anhydrous cosmetics such as lipsticks, foundations, and mascaras, it belongs to the emollient category. In products, it functions by reducing surface friction, providing a smooth glide during application, and mimicking skin's natural lipids to fill minor imperfections. Its hydrophobic nature helps stabilize formulations and supports even distribution of pigments. As a skin conditioning agent, it promotes a supple texture without greasiness, making it suitable for long-wear makeup. The ingredient's stability in oil-based systems prevents separation and enhances overall product performance.
