CASl84380-01-8 alpha-Arbutin 4-hydroquinone-alpha-d-glucopyranoside alpha-arbutin Top quality manufacturer supply

Arbutin, also known as arbutin, chemical formula C12H16O7, is a component extracted from the leaves of the bear fruit of the rhododendron family.
Arbutin is mainly extracted from Bearberry leaves. Arbutin can also be found in some fruits and other plants. It has the effect of brighting the skin, can quickly penetrate into the skin without affecting skin cells, and combines with tyramine acid, which causes the production of melanin. It can effectively block the activity of tyrosinase and the generation of melanin, and accelerate the decomposition and elimination of melanin.

[Precautions]
1. The aqueous solution of A-Arbutin is stable between PH3.5 and 6.5; The recommended temperature is below 70℃.
2. A-arbutin can achieve better results when used together with chemical UV absorbent with good solubility (sunscreen) and ethanol;
3. A-arbutin can be applied to the water phase of the formula at 50℃, or can be added at a very late stage of the formula;
4. Adding an appropriate amount of vitamin E in the formula (generally 1% ~ 3%) has a stabilizing effect on it, adding an appropriate amount of vitamin E (the recommended amount of addition is 0.1-0.2%) can prevent body discoloration.
5. In the emulsifying system, adding vegetable oils such as grape seed oil and sweet almond oil containing oleic acid and linoleic acid can promote the synergistic effect of arbutin; The pH of cream emulsion system is controlled at 6-7.
