Arbutin, also known as arbutin, is a white needle-like crystal or powder. The leaves extracted from bear fruit can inhibit the activity of tyrosinase in the body and prevent the production of melanin, thus reducing the pigmentation of the skin, removing spots and spots, and also having the functions of sterilization and anti-inflammation. Mainly used for the preparation of advanced cosmetics.
Arbutin is a natural active substance from green plants, and it is a skin decoloring component that integrates "green plants, safety and reliability" and "efficient decoloration". It can quickly penetrate into the skin, effectively inhibit the activity of tyrosinase in the skin without affecting the cell proliferation concentration and blocking the formation of melanin. By directly combining with tyrosinase, it accelerates the decomposition and excretion of melanin, thus reducing skin pigmentation and removing spots.
It is the safest and most effective whitening raw material at present, and it is also the ideal skin whitening and freckle removing active agent in 2 1 century.
Precautions:
1, arbutin is easy to decompose in acidic environment. Pay attention to control the pH of systems such as cream emulsion at 5-7.
2. Dissolve arbutin in a small amount of water at 50℃ and add it at 50℃ after the cream is emulsified.
3. Add an appropriate amount of antioxidants into the cosmetic system to prevent discoloration.
4. After the emulsion is emulsified, add NaHSO3 and Na2SO3 (recommended dosage is 0.3-0.4%) which have been dissolved with a small amount of water at 50℃.
5. Adding natural vegetable oil containing oleic acid and linoleic acid can promote the synergistic effect of arbutin.
6. Adding 0.8-1.0% azone to the cosmetic system can promote the absorption of arbutin and prevent arbutin from depositing on the skin.
