Whitening Alpha Arbutin Powder for Brighter Skin

Name and Origin

Alpha arbutin powder, the chemical name is 4-hydroquinone-alpha-D-glucopyranoside, also known as 4-hydroxyphenyl-alpha-D-glucopyranoside, its English alias is 4-Hydroquinone- alpha-D-glucopyranoside, a-Arbutin, etc., CAS number is 84380-01-8, molecular formula is C12H16O7, molecular weight is 272.25g/mole1235678.
Source: Mainly derived from the leaves of bearberry, a plant in the Ericaceae family.

Physical properties
Appearance: white powder or needle-shaped crystals.
Solubility: easily soluble in hot water and ethanol, slightly soluble in cold water.
Optical rotation: The optical rotation of α-arbutin (i.e. alpha arbutin) is about 180 degrees, which is one of the differences in physical properties from β-arbutin. The optical rotation of β-arbutin is about - 60 degrees.
Melting point: 203 - 207±1℃.

The Efficacy and Role of Alpha Arbutin Powder
1.Whitening and Lightening
Alpha Arbutin Powder is an efficient whitening ingredient. It can inhibit the activity of tyrosinase and block the formation of melanin, thereby reducing skin pigmentation and achieving whitening and lightening effects. Studies have shown that α-arbutin can significantly inhibit the activity of tyrosinase at a lower concentration, and its effect is nearly 10 times that of arbutin. In addition, alpha-arbutin can promote skin whitening and is suitable for all skin types.
2.Antioxidant and Anti-inflammatory
Alpha-Arbutin powder has antioxidant properties and protects the skin from damage caused by UV rays. It can reduce erythema and wrinkles caused by exposure to external light, and effectively inhibit epidermal hyperplasia of the skin caused by photosensitivity. In addition, alpha-arbutin also has anti-inflammatory and repairing effects, which can help heal damaged skin.
3.Protect Collagen Tissue
Alpha Arbutin Powder can protect collagen tissue, reduce the expression of symptoms caused by light, and increase the expression of COL-1. This helps maintain skin elasticity and firmness and fights skin aging.
4.Security and Stability
Alpha-arbutin powder does not produce hydroquinone when used, so it will not cause toxicity and irritation to the skin, nor will it cause side effects such as allergies. Its chemical properties are more stable than β-arbutin and can be more easily added to various whitening and brightening cosmetics.

How to Use and Precautions
When using Alpha Arbutin Powder, you need to pay attention to dissolving it in a small amount of water at 50°C, and add it at 50°C after the cream is emulsified. In addition, an appropriate amount of antioxidants should be added to the cosmetic system to prevent discoloration. Adding natural vegetable oils containing oleic acid and linoleic acid can promote the synergistic effect of arbutin. Adding 0.8-1.0% azone can promote the synergistic effect of arbutin. Absorption, while preventing the precipitation of arbutin on the skin.

To sum up, Alpha Arbutin Powder is a multifunctional skin care ingredient. It can not only whiten and lighten spots, but also has antioxidant, anti-inflammatory, collagen tissue protection and other functions. When using it, you should pay attention to the correct adding method and precautions to ensure the best effect.

Use in cosmetics
Effect
It is a pure, water-soluble active ingredient that promotes skin whitening and is suitable for all skin types. It inhibits the formation of epidermal melanin by blocking the oxidation of tyrosinase and dopa. The whitening effect is rapid and effective. It can inhibit the activity of tyrosinase at a very low concentration. The intensity is that of arbutin (here Refers to nearly 10 times that of β-arbutin), and has no effect on cell growth at higher concentrations. It has a significant effect on the spots caused by ultraviolet burns. Compared with the existing single ingredients, it has higher stability and efficacy in lightening spots and reducing skin damage after ultraviolet irradiation, making the skin appear brighter and more radiant.
It can be used to prepare skin care cream, freckle cream, pearl cream and other cosmetics. It can not only whiten skin care, but also reduce inflammation and resist irritation.
Adding amount: The recommended adding amount in cosmetics is 0.1% - 3%.
