1. The difference betweenα- Arbutin andβ- Arbutin
Most of the Arbutin isβ- Arbutin,α- Arbutin is produced by only a very small number of manufacturers and the price is eight times of the former one,but the whitening effect is fifteen times of β- Arbutin.
The biggest difference is rotation in physical properties between them , α-Arbutin is about 180 degrees, andβ- Arbutin is about -60.

2.Is Arbutin synthetic or natural ? content ?
α- Arbutin is natural, β- Arbutin is synthetic. The content is more than 99.5%.
3. What are the limits of adding temperature and how much ? how much is the PH value limited in ?
1. Arbutin is easy to decompose in an acidic environment, pay attention to cream system pH and controlled in 5-7.2.dissolve the Arbutin in a small amount of water at 50℃,add when the cream emulsion completed at 50℃.
3.Adding proper amount of antioxidant system to prevent discoloration in cosmetics
4.add a small amount of water dissolved NaHSO3 and Na2SO3 at 50℃ when the emulsion is completed , (recommended the addition amount of 0.3-0.4%).
5. Add the natural plant oil containing oleic acid and linoleic acid can promote the Arbutin synergistic effect.
6. Adding 0.8 -1.0% of cosmetics in the system of azone can promote the absorption of Arbutin, At the same time, to prevent the precipitation of Arbutin on the skin.
4. How about the stability of the Arbutin?
The Stability ofα- Arbutin is good butβ- Arbutin’s is slightly worse in contrast.
5. How much is the added amount of Arbutin?
The adding amount of Arbutin is related to the whitening and freckle effect ,the effect is not obvious when the adding amount is blow 3％and it will be effective in a long time. According to the foreign related company's experimental results, the adding amount of Arbutin is best in 7%-9%.according to the situation of our country, considering two factors of cost and effect, it is suggested between 6-7%.
6. What is the function of Arbutin?
Arbutin is a natural active substances derived from the set of "green plants, safe and reliable" and "efficient decolorizing" three harmonious unity in one of the skin bleaching component. it can quickly penetrate into skin ,not affecting cell proliferation in the concentration at the same time and can effectively inhibit the activity of tyrosinase in the skin, blocking the formation of melanin, directly through its own binding and tyrosine enzyme, accelerating the melanin decomposition and excretion, thus reducing the skin pigment deposition, eliminating stains and freckles, but will not produce toxicity, irritation, sensitization and Other side effects on melanoma cells, at the same time it also has bactericidal, anti-inflammatory function. It is the most popular as a safe and effective whitening material and the ideal material to whitening freckle in twenty-first century.
Benefits:
1.For advanced cosmetics，it can be made into cream, freckle cream, senior pearl cream and can beauty skin care, but also anti-inflammatory, anti irritation.
2.Burning and scald ingredient: Arbutin is a major component of model burn and scald, characterized by rapid analgesic, anti-inflammatory and strong, rapid elimination of swelling, heal quickly, does not leave scar. Dosage: spray or smear.
3.Intestinal anti-inflammatory drug raw materials: sterilization, anti-inflammatory effect, no toxic side effect。
Additional remarks: In fact, the main effect of Arbutin is a skin lightening effect (skin lightening) can make the skin look young and beautiful.

7. Why is your price of α- Arbutin 4000 while Others’ is just about 2000?
Our company is professional to produce the α- Arbutin andβ- Arbutin, there are many who quote price 1800 - 2800 Yuan /kg now on the market, the alpha Arbutin is the normal market price of 4200 Yuan. DSM offers the highest, 9000 Yuan /Kg, in the face of such confusion price, according to the market research, our company took the α- Arbutin blow 3000Yuan/kg to do the testing and found that α- Arbutin which in accordance with the proportion of ginseng β- Arbutin.

Attention：please be careful when you buy the α- Arbutin of low price, we have tested several times, found that almost β- Arbutin which mixed in α- Arbutin , theβ- Arbutin market price is just 700 Yuan /kg.
8. How about the dissolution ratio of α- Arbutin in water?
About 150 grams per liter 0.15:1 1 liter is 1000 grams of 150:1000.
9. Does Arbutin ingredient in cosmetics have side effect?

Ursolic Acid:
Ursolic acid is a kind of three terpenoids present in natural plants, with sedation, anti-inflammatory, antibacterial, anti diabetic, antiulcer, reduce blood sugar and Other biological effect. In recent years, experts found that it has anti carcinogenic, tumor promotion, teratoma induced F9 cell differentiation and angiogenesis, it is very likely to become the new anti-cancer drugs with low toxicity and high efficiency. In addition, ursolic acid has the effect of anti oxygen function, so it is widely used in medicine and cosmetics raw materials.
