China Cosmetic Grade Beta-Arbutin CAS No 497-76-7

Arbutin can quickly penetrate into the skin, effectively inhibiting the activity of tyrosinase in the skin and blocking the formation of melanin without affecting the proliferation of skin cells. By combining itself with tyrosinase, it accelerates the decomposition and excretion of melanin, thereby reducing skin pigmentation. It is one of the popular cosmetic raw materials and a commonly used cosmetic active agent. Adding Arbutin to hair conditioners can inhibit the growth of dandruff. Arbutin can be combined with amphoteric surfactant cations to reduce skin irritation, some even non-irritating, and can control the adhesion of surfactants.
