α-Arbutin Powder

Premium α-Arbutin Powder – Advanced Skin Brightening Ingredient for Professional Formulations

Hunan Clover Origins Biotech Co., Ltd. provides pharmaceutical grade α-Arbutin Powder with purity certified at 99% by HPLC. Our product is obtained by regulated enzymatic biosynthesis as a water-soluble white crystalline active ingredient with specific optical rotation between +174° to +184°. Our yearly production capacity is more than 5,000 tons and we are FDA, ISO 9001, HACCP, FSSC 22000, Kosher and Halal certified. This ensures consistent, batch-to-batch quality to cosmetic manufacturers worldwide. This premium ingredient provides 10x the tyrosinase inhibition of Beta-Arbutin, offering your formulations a safe, stable and highly effective alternative to hydroquinone for depigmentation and skin tone correction.

What Is α-Arbutin and Why Does It Matter?

Alpha-Arbutin is a biosynthetic hydroquinone glycoside, chemically known as 4-Hydroxyphenyl-α-D-glucopyranoside (CAS No. 84380-01-8). The Alpha form is more stable and more effective than the naturally occurring Beta isomer.

It works by competitive inhibition of tyrosinase (the enzyme that produces melanin). This means your formulations can target dark spots, melasma and post-inflammatory hyperpigmentation without any cytotoxic adverse effects.

This addresses three big issues for formulators. First of all, it replaces banned hydroquinone with a safer alternative. Secondly, it is more potent than Beta-Arbutin, which is quickly hydrolyzed. Third, it works in water-based systems where other actives do not.

Technical Specifications

Key Properties and Performance Advantages

Our product exhibits good water solubility (about 150 g/L at 20 °C) and is therefore most suited to aqueous and hydrogel settings. What sets it apart is its specific optical rotation of +174.0°~+184.0°, which is higher than the weaker Beta-Arbutin.

It is stable in the pH range 3.5 to 6.5, therefore it offers some flexibility for use in serums, creams and gels. It can also withstand temperatures of up to 100°C for short periods consistent with the manufacturing process.

Rigorously quality controlled. We maintain residual hydroquinone strictly below 10 ppm, with purity values of ≥99.5% by HPLC. This ensures dermatological safety and regulatory compliance in China, the EU and the US.

Applications in Professional Skincare Formulations

α-Arbutin Powder is used in three high-value application categories.

Advanced Brightening Serums & Ampoules: The secret behind spot correction treatments. It is water soluble and can readily be combined with hyaluronic acid or derivatives of Vitamin C such as Magnesium Ascorbyl Phosphate in oil free bases. The typical doses for best efficacy are from 1% to 2%.

Medical-Grade Post-Procedure Creams: Used in cosmeceuticals to address post-inflammatory hyperpigmentation (PIH), particularly following laser treatments or chemical peels. The product is stable and can be utilized in O/W and W/O emulsion systems without rapid oxidation if the manufacturing temperatures are below 70°C.

Suncare and Day Creams: Unlike retinol, this substance is not photosensitive. It inhibits the melanin formation prompted by UV exposure; consequently it is compatible with organic and inorganic UV filters in daily use formulations.

FAQ

Q: What is the difference between Alpha-Arbutin and Beta-Arbutin?

A: Alpha-Arbutin is roughly 9 to 10 times more efficient in blocking tyrosinase than Beta-Arbutin. It has better stability in formulations and it doesn't hydrolyze as quickly, so it is chosen for premium cosmetic goods.

Q: Can I use α-Arbutin on sensitive skin?

A: Yes. It is mild and non-irritating. It does not induce redness, peeling or cytotoxic effects as hydroquinone does. It is frequently used for after-care and is suitable for all skin types.

Q: Can I use α-Arbutin with Vitamin C/Niacinamide?

A: Definitely. It acts synergistically with derivatives of Vitamin C and Niacinamide to boost the brightening properties. Maintain pH stability between 3.5-6.5.

Q: What is the recommended usage concentration?

A: For professional formulas, concentrations between 1-2% are typically effective. In cases of focused spot treatments under dermatological direction, higher concentrations can be used.

Q: How do I store the product?

A: Store in a cool, dry place away from direct sunlight. Keep containers securely closed to exclude moisture. Proper storage will stabilize ingredients and improve shelf life.

Q: Do you have any examples and technical documents?

A: Yes. Free samples and technical documents are delivered within 12 hours. Our team offers full formulation support, analytical testing and regulatory guidance throughout your product development.
