Cosmetic-grade α-Arbutin

α-Arbutin is a skin-brightening and depigmenting agent that acts by inhibiting tyrosinase, a key enzyme in melanin biosynthesis. It is gentler and more stable than β-arbutin and hydroquinone, making it suitable for daily use in sensitive skin formulations. α-Arbutin may be used as an analytical reference standard for the determination of the analyte in cosmetics by high-performance liquid chromatography with UV detection (HPLC-UV) method.

Cosmetic Grade α-Arbutin Product Overview

α-Arbutin is widely utilized in both skincare and cosmetic products due to its various beneficial properties. It is primarily employed for its skin-lightening and brightening effects. It helps to reduce the appearance of hyperpigmentation, age spots, and melasma, promoting a more even skin tone. It is often incorporated into formulations to provide skin-enhancing benefits. By imparting a brightening effect, it helps to create a more luminous and youthful appearance. Additionally, the antioxidant properties of α-Arbutin make it useful in protecting the skin against free radicals and environmental damage, contributing to overall skin health.

α-Arbutin Production

α-Arbutin is a synthetic substance that can be produced by enzymatic glycosylation of hydroquinone in the presence of α-amylase and dextrin. Producing α-arbutin via microbial fermentation is an efficient and eco-friendly alternative to chemical synthesis. The process relies on glucosyltransferases to attach glucose to hydroquinone (HQ), yielding α-arbutin with high regioselectivity and purity. It has been done in recombinant Escherichia coli, using amylase of Bacillus subtilis and sucrose phosphorylase of Leuconostoc mesenteroides.

Microbial Hosts for α-Arbutin Production

Commonly Used Strains	Capabilities
Escherichia coli	Recombinant production of glucosyltransferase	Engineered for high expression
Bacillus subtilis	GRAS host for UDP-glucose-based production	High secretion potential
Xanthomonas campestris	Natural source of amylosucrase	Produces α-arbutin from sucrose & HQ
Corynebacterium glutamicum	Engineered platform strain	Good for large-scale bioproduction

Substrate Feeding Strategy

Substrate	Function	Feeding Strategy
Hydroquinone (HQ)	Acceptor molecule	Typically 0.5–2 g/L; toxic above 3 g/L
Sucrose / Glucose	Sugar donor (UDP-glucose precursor)	Fed to maintain carbon flux
Uridine	Precursor for UDP-glucose	Used in some engineered strains

Extraction and Purification

Centrifuge culture to remove cells

Filter supernatant (0.45 μm)

Concentrate via rotary evaporation or membrane filtration

Purify Methods

Ion exchange chromatography
Reverse-phase HPLC
Crystallization (from ethanol-water)

Customer Reviews

Partnering on microbial α-arbutin production has been a game-changer for us. The purity and consistency exceeded our expectations, and the team’s tech transfer support was truly world-class. We’ve already integrated it into our brightening serum line with excellent results.

-Dr. Isabelle Chen

R&D Director

We’ve worked with multiple suppliers before, but this team’s fermentation-derived α-arbutin was by far the cleanest and most stable. Their documentation for cosmetic regulatory use in Asia was extremely helpful, and deliveries have always been timely.

-Dr. Marisol Rivera

Product Development Manager

The cosmetic-grade α-arbutin met ISO and EU cosmetic safety requirements and was easy to incorporate into both emulsions and gels. We especially appreciated the detailed COA, heavy metal analysis, and microbial test reports. Highly recommended for premium skincare brands.

-Ms. Laura Feldmann

Senior Formulation Scientist

We needed an eco-friendly and non-synthetic alternative for our skin tone corrector. Their bioproduction process and high-purity α-arbutin gave us the edge in launching a truly green cosmetic. Customer support was fast and transparent.
