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.

Precautions for use:
1, Arbutin is easy to decompose in acidic environment, pay attention to the pH value of the system is controlled above 6.0;
2, when used, should be dissolved in a small amount of water at 45 ° C, after the cream is completely emulsified at 45 ° C;
3, should Add appropriate amount of antioxidants such as sodium bisulfite for formula system;
4, when formulated, can be effectively compatible with zwitterionic surfactants and anionic surfactants;
5, adding natural vegetable oil containing oleic acid, linoleic acid, Promote the synergistic effect of Arbutin;
6, azone, octadecyl dimethylamine oxide, etc. can promote the absorption of Arbutin;
