FAQ (Frequently Asked Questions)
1. What is CHEMKG Arbutin-Alpha?
CHEMKG Arbutin-Alpha is a high-purity, stabilized form of Alpha-Arbutin developed for advanced skin-brightening and pigmentation-control formulations in the personal care industry. This version offers improved efficacy and stability compared to traditional Beta-Arbutin.
2. How does CHEMKG Arbutin-Alpha differ from Beta-Arbutin?
Unlike Beta-Arbutin, which is less stable and may degrade over time, CHEMKG Arbutin-Alpha features a more stable α-glucosidic bond. This results in:
Enhanced stability in formulations
Higher efficacy in inhibiting tyrosinase activity (melanin production)
Reduced risk of hydroquinone release
Greater skin compatibility and safety profile
3. Why was Beta-Arbutin replaced with CHEMKG Arbutin-Alpha?
The transition to CHEMKG Arbutin-Alpha aligns with modern skincare demands for safer, more effective skin brightening solutions. Alpha-Arbutin demonstrates superior performance in reducing dark spots and uneven skin tone while offering better formulation stability in a wider pH range.
4. What are the benefits of using CHEMKG Arbutin-Alpha in cosmetics?
Brightens and evens out skin tone
Reduces appearance of hyperpigmentation, age spots, and melasma
Safe for long-term use
Stable in light and heat
Works effectively at low concentrations (0.2% to 2%)
5. What is the CAS number and INCI name of Arbutin?
CAS Number: 84380-01-8 (for Alpha-Arbutin)
INCI Name: Alpha-Arbutin
Note: Traditional Beta-Arbutin has a different CAS number (497-76-7) and slightly different properties. CHEMKG Arbutin-Alpha refers specifically to the Alpha-Arbutin form.
6. Is CHEMKG Arbutin-Alpha safe for all skin types?
Yes. Alpha-Arbutin is known for its excellent safety profile, making it suitable for all skin types, including sensitive skin. It is non-irritating and does not sensitize the skin, unlike some harsher brightening agents.

Brightening serums and creams
Spot correctors
Anti-aging formulations
Sunscreens
Whitening lotions and toners
Eye creams targeting dark circles
8. How is CHEMKG Arbutin-Alpha incorporated into formulations?
It is typically water-soluble and added during the cooling phase of formulation to prevent degradation. The recommended usage level is 0.2% to 2%, depending on the desired activity and product type.
9. Is CHEMKG Arbutin-Alpha compatible with other actives?
Yes. It works well with a variety of ingredients including niacinamide, hyaluronic acid, vitamin C derivatives, licorice extract, and peptides. It is also stable across a wide pH range (pH 3.5–6.5), making it versatile in formulation.
