Alpha Arbutin Powder

High-End Cosmetic Grade Alpha Arbutin Powder Skin Whitening

1. Introduction of Alpha Arbutin Powder:

Alpha arbutin is a natural hydroquinone glycoside—you’ll find it naturally in plants like bearberry and blueberries, if you’re curious. For cosmetic use, the industrial-grade version (usually made via biosynthesis or chemical synthesis) has really high purity—makes sense, right? It’s designed specifically for skincare. That’s why it mixes so easily into all kinds of skincare formulas, no fuss. It’s an epimer of beta-arbutin, with a positive specific rotation (+174.0～+184.0°)—the main thing that sets it apart from beta arbutin, and you don’t need a chemistry degree to tell them apart. Anyway, what really makes it great for skincare is its solid stability and how well it soaks into your skin. It blends smooth into any cosmetic product, so you never have to deal with clumps or weird separation. And since there’s no irritating junk in it, even folks with sensitive skin can use it without any hassle.

2. Characteristics:

HIgh Purity: 99.9%

Good Solubility:Soluble in water, 151 g / l (20 ° C), in warm thermal (<70 ° C) or cold state, easy to fuse the other components in the formulation.

Good stability:Relative to β-arbutin, A-arbutin is not easily discolored and degraded;

After reaching 100 ° C. , A-arbutin remains stable;

At pH -6.5, α-arbutin is more stable than other whitening materials;

High effectiveness:Alpha-arbutin inhibits melanoma tyrosinase only, and its mechanism is presumed to be mixed inhibition. And the inhibitory strength of α-arbutin is 10 times that of β-arbutin.

High Security:Hydroquinone content ≤ 10ppm
The concentration of a-arbutin added is 7%, and only more than 7% of arbutin may be sensitive to light and low in irritation.
The a-arbutin skin care product contains hydroquinone in a concentration of less than 20 parts per million. Under such a low concentration limit, hydroquinone does not cause side effects such as anti-blackness of the skin.

3. Whitening Mechanism: 

Alpha-arbutin molecule contains two structural functional groups:

*Glucose residue - is hydrophilic and easily soluble in water.

*Phenol-melanin synthetase inhibition

Arbutin introduces a glucose molecule into the molecule, which reduces the stimulating effect, has the ability to interfere with melanocytes, and dilute the formed melanin. The sunscreen ability is good and the blemish effect is strong. It is used to treat pigments such as chloasma and freckles, and has good curative effect, especially sunburn.

4. Six steps for Whitening :

Alpha-Arbutin can effectively inhibit the activity of melanin-promoting enzymes during the growth of black.

1. Prevention: Reduce the absorption of ultraviolet light.

Physical sun protection and chemical sun protection:

2. Protection: Anti-free radical, anti-inflammatory.

3. Activation of melanin: reducing the products and activities of melanocytes.

4. Melanin production process: inhibits the activity of enzymes that promote melanin growth.

A- Arbutin can inhibit the activity of tyrosinase, inhibit the formation and excessive deposition of melanin, and reduce the appearance of pigmentation, thus achieving the purpose of whitening and freckle.

Arbutin as a whitening agent, its whitening mechanism is mainly to inhibit monophenolase activity, prevent tyrosinase from catalyzing the conversion of L-tyrosine to L-dopa, and α-arbutin to tyrosinase monophenol. Enzyme has a strong inhibitory effect, while α-arbutin has a certain activation effect on the tyrosinase diphenolase, and the mechanism of action is a competitive and non-competitive mixed activation. Numerous clinical studies have shown that α-arbutin has a unique effect in promoting even skin tone.

5. Generated melanin:

Reduce the generated melanin and fade and melanin.

6. Auxiliary steps:

Promote the metabolism of cells and smooth the excretion of melanin from the surface of the skin;

7. Main effects:

*Whitening spots:

Α-arbutin can rapidly penetrate deep into the skin, and can inhibit the activity of tyrosinase present in the pigment blast cells deep in the stratum corneum without affecting the cell proliferation concentration. It prevents the formation of melanin and forms a double effect on the surface of the skin, inhibiting the formation of melanin and achieving a whitening effect.

*Repair damage:

Arbutin can promote skin cell growth and help heal wounds. Human skin cells in vitro culture experiments show that arbutin

When arbutin is present in a trace amount (10-3mmol/L), the cell growth rate is significantly improved, and the skin has a nursing function.

*Antioxidants:

It also maintains cell viability while repairing damage.

*Sterilization and anti-inflammatory:

Arbutin is the main ingredient of the new type of scald medicine. It is characterized by rapid analgesia, strong anti-inflammatory ability, rapid elimination of redness, rapid healing and no scarring. Therefore, it is also a good medicine for inflammatory skin.

8. Suggested Addition Amount:

*Safe use of Cosmetics:5%

*The Recommended dosage:0.2%~2%

Over the counter OTC and Medicinal burns and other external use:10% 

9.Function:

When you talk about alpha arbutin for skin, its best traits are how precisely it brightens and how gently it repairs—that’s why so many people swear by it in their daily routines.

First off, it goes straight for melanin at the source. It never messes with your skin’s natural cell function; instead, it latches right onto the active site of tyrosinase—the enzyme that actually kickstarts melanin production. Plenty of skincare labs have done in vitro tests, and all of them back this up: its tyrosinase inhibition rate is over 9 times higher than beta arbutin’s. So basically, it stops melanin from forming before the process even gets going.

Second, it helps fade the dark spots you already have. It’s not just about blocking new melanin—it also speeds up how fast existing melanin in your skin breaks down and gets cleared away. This is super helpful for lightening UV-induced pigmentation, like sunspots or chloasma—you know the ones that linger long after a beach day or a hike, even when you’re out of the sun.

And here’s the best part: unlike harsher brightening ingredients (think certain strong acids), it’s gentle enough to use every single day. It even has anti-inflammatory benefits, which help heal those little bits of skin damage that usually come with sun exposure. So it’s not just making your skin brighter—it’s keeping it healthier, too.
