    Product Description

    SepiWhite (INCI: Undecylenoyl Phenylalanine) is a bioactive, skin-brightening ingredient developed by SEPPIC, a French specialty chemicals company. Chemically, it is a lipoamino acid derived from phenylalanine, an essential amino acid, and undecylenic acid, a fatty acid. It exists as a white, odorless powder that is water-soluble and stable across a wide pH range, with optimal performance in slightly alkaline conditions. Notably, it is Ecocert-certified, free from preservatives, and compatible with various cosmetic ingredients, making it suitable for clean beauty formulations .
