The Trusted Brightening Ingredient for Global Skincare

ZLEY® α-Arbutin (CAS 84380-01-8):

The Trusted Brightening Ingredient for Global Skincare

Product Overview

α‑Arbutin (also known as arbutin) is a naturally derived bioactive ingredient primarily extracted from the leaves of the bearberry plant. It rapidly penetrates the skin without compromising cell viability. By binding with tyrosinase—the key enzyme in melanin production—α‑arbutin effectively inhibits tyrosinase activity and melanin synthesis. It also accelerates the breakdown and elimination of existing melanin. Additionally, it helps protect the skin from free radical damage. Its excellent water solubility makes it a popular choice in brightening products, especially in Asian markets—for example, as a signature brightening ingredient in Shiseido formulations.

ZLEY® is a professional supplier of α-Arbutin (CAS 84380-01-8), providing stable quality, technical support, and global delivery services covering over 60 countries.

Frequently Asked Questions (FAQ)

Q1: What is the difference between α-Arbutin and Beta-Arbutin?

A: α-Arbutin is more stable and significantly more effective than Beta-Arbutin. Studies show that α-Arbutin provides up to 10 times stronger tyrosinase inhibition than Beta-Arbutin, making it the preferred choice for cosmetic formulations seeking potent brightening effects.

Q2: What is the recommended pH range for formulations containing α-Arbutin?

A: α-Arbutin is unstable under acidic conditions (pH < 5.0). For optimal stability and efficacy, the final formulation pH should be above 6.0. Avoid combining with acidic ingredients (e.g., high concentrations of AHAs) unless proper stabilization measures are taken.

product type and desired results.

Q3: Does ZLEY® α-Arbutin require an antioxidant in the formula?

A: Yes. To maintain stability and prevent oxidation, it is recommended to add an antioxidant (such as Vitamin E, BHT, or sodium metabisulfite) to the formulation. This is especially important for water-based or emulsion systems exposed to air and light.

Q4: How should ZLEY® α-Arbutin be processed during manufacturing?

A: Dissolve the powder in water at temperatures below 45°C (113°F). Avoid excessive heat, as prolonged high temperatures may degrade the active. For best results, add the dissolved α-Arbutin during the cooling phase of emulsion manufacturing.
