Alpha arbutin powder is a naturally active substance isolated from various plant genera. Containing strong hydrophilic glucose residues, it can effectively retain skin moisture and easily penetrate the outer layer of the skin; Phenol groups are effective inhibitors of tyrosinase, which can effectively inhibit the biological activity of tyrosinase, limit and reduce the formation of melanin in cells, and have a whitening effect.
★Is Alpha Arbutin Powder water-soluble or oil-soluble? How to incorporate it?
Alpha-Arbutin is water-soluble. It dissolves readily in water, glycols (propylene glycol, butylene glycol), and glycerin. It is practically insoluble in oils. Incorporation method: Simply add Alpha-Arbutin to the water phase at room temperature or with gentle heating (up to 60°C). It dissolves quickly and remains clear. For clear serums, dissolve directly in deionized water. No special equipment is needed.
★What is the recommended dosage of Alpha Arbutin Powder in cosmetic formulations?
Due to its high potency, lower concentrations are effective:
Brightening serums / ampoules: 0.5-2% (optimal 1-2%)
Anti-spot creams / lotions: 1-2%
Daily moisturizers / toners: 0.5-1%
Sheet mask essences: 0.5-1.5%
Rinse-off products (cleansers, masks): 1-2% (less critical due to short contact)
For first trials, start at 1%. Do not exceed 2% in leave-on products for most markets (though no official limit, higher concentrations may cause mild irritation in sensitive individuals).
★Can Alpha Arbutin Powder be combined with other whitening or active ingredients?
Yes, Alpha-Arbutin is highly compatible and synergistic with many actives:
With niacinamide: Excellent combination for brightening and barrier repair (both water-soluble, stable at pH 5-6).
With tranexamic acid: Powerful melasma-fighting duo.
With vitamin C derivatives (MAP, SAP, ethyl ascorbic acid): Multi-target antioxidant and whitening.
With kojic acid: Additive tyrosinase inhibition (but note kojic acid stability issues).
With retinol: Can be used, but retinol may cause irritation; alpha-arbutin does not.
With AHAs/BHAs: Yes, but keep pH above 4.0 to ensure alpha-arbutin stability.
Avoid combining with high concentrations of strong acids (pH <3.5) for long-term storage.
★Is Alpha Arbutin Powder approved for cosmetic use in the EU, USA, and China?
EU: Listed in CosIng as Alpha-Arbutin (CAS 84380-01-8) with no concentration restriction (typical use ≤2%).
USA: Allowed as a cosmetic ingredient; FDA has no specific ban.
China (NMPA): Listed in IECIC 2021 (INCI: α-熊果苷) with no maximum concentration specified (typical use ≤2%).
We provide full registration documents including COA, MSDS, TDS, and China compliance declaration.
★What products is Alpha Arbutin Powder suitable for?
Whitening serums, spot-correcting creams, brightening toners, facial masks, lotions, sunscreens and sensitive-skin brightening products.
★What is the recommended usage rate in formulations?
Recommended addition concentration: 1%–3%, can be adjusted according to product positioning and efficacy requirements.
★What pH range is suitable for Alpha Arbutin Powder?
It remains stable and effective in pH 4.5–7.0 (weakly acidic to neutral environment).
★Is Alpha Arbutin Powder irritating to skin?
It is extremely mild and non-irritating, with extremely low sensitization risk, suitable for long-term daily use.
★What is the difference between Alpha Arbutin Powder and Beta-Arbutin?
Alpha-Arbutin: Higher stability, stronger tyrosinase inhibition, safer, suitable for high-end whitening products
Beta-Arbutin: Lower cost, weaker efficacy, easier to decompose
