Overview
What is Alpha‑Arbutin? Alpha‑Arbutin is a water‑soluble cosmetic active ingredient, listed in China’s Inventory of Existing Cosmetic Ingredients. It appears as white crystalline powder. Its mechanism is to competitively inhibit tyrosinase activity and interfere with melanin‑generation pathways. It can be used as a raw material for cosmetic formulations targeting even‑toned skin. Compared with Beta‑Arbutin, Alpha‑Arbutin delivers better stability in formulation systems. It is compatible with aqueous and emulsified formulations and features favorable thermal stability. Hydroquinone‑related impurities are controlled within specified limits during production. According to EU SCCS assessment, the maximum authorized concentration is 2% for leave‑on facial cosmetic products and 0.5% for leave‑on body care products. It is applicable to leave‑on cosmetic formulations such as even‑toning serums, creams, facial masks and after‑sun care products.
