Alpha Arbutin Powder for skin whitening
Introduction:
Alpha-arbutin (4-hydroxyphenyl-D-lucopyranoside) is a glycoside, it inhibits tyrosinase and prevents the formation of melanin.
Therefore alpha-arbutin is a functional active ingredient for skin lightening. 
Specification:

Premix solution :
Premix solution can be added onto formulation before emulsification.
Alpha-Arbutin Effects: Safety, Stability and Efficiency
1.Alpha-Arbutin Safety
Experiments have shown that α-arbutin has no cytotoxicity: α-arbutin can significantly reduce activity of tyrosinase in melanocytes; and it does not affect survival activity of cells. (Biological Effects of Arbutin on Skin Melanocyte Song Qiru, Li Wuping, Journal of Ningxia Medical College, 2004, period 05)
In July 2015, α-arbutin was identified as a safe and effective cosmetic whitening raw material by European Committee for Consumer Safety Science (SCCS). According to the latest opinion of SCCS, it is safe when α-arbutin is added in facial care product less than 2% and in body care product less than 0.5%.
2.Alpha-Arbutin Stability
Alpha-arbutin transformed by biological enzyme has high purity and stable structure (heat resistance and light resistance). It is not decomposed by β-glucosidase in human skin when using it. Alpha-arbutin has excellent stability in production and application.
3.Alpha-Arbutin Efficiency
Studies have shown that α-arbutin inhibits activity of tyrosinase by specific reversible competition. It blocks melanin formation, and accelerates decomposition and excretion of melanin. Accordingly, α-arbutin reduces deposition of skin pigments, and achieves whitening and anti-freckle effect. Therefore, α-arbutin has higher whitening efficacy and durability.
4.Other Alpha-Arbutin Effects
Alpha-Arbutin also has functions of moisturizing, healing wounds, sterilizing and anti-inflammatory. It is currently considered as a safe and effective whitening ingredient.

Function:
Ensures an even, lighter skin tone

Reduces the degree of skin tanning after UV expos
Application:
Intensive skin lightening products
Even skin tone care products

BB/CC cream
Arbutin Uses
1.α-Arbutin is easily soluble in water, and its solubility is 151 g/L (20°C).
2.It is compatible with other active ingredients at temperatures less than 60°C or low-medium temperature.
3.When prepare skin care products, add appropriate concentration antioxidants to prevent discoloration, such as adding Sodium Ascorbyl Phosphate.
4.Arbutin is not easily decomposed in reaction temperature range of 30~50 °C.
5.The pH of arbutin should be controlled at 5-7. Its stability should be controlled within adaptive range of human skin. Arbutin will change color in alkaline condition, and will decompose a little in acidity condition.
6.In order to accelerate absorption of arbutin, Sodium Ascorbyl Phosphate can be added in the formulation. Natural Penetrant Can Consider Piperine Or Phloretin.
7.Recommended dosage: 0.5-2.0%

Recommended dosage in different cosmetics:

In the preparation of whitening cream, α-arbutin can be combined with other whitening ingredients such as Ascorbic Acid 2 Glucoside (AA2G), niacinamide, etc. The recommended dosage of each ingredient is: α-arbutin: 1.0-2.0%; nicotinamide: 0.5-1.0%; AA2G: 1.0-2.0%.
