Arbutin

Product Description

Green Stone Swiss supplies high-purity Arbutin manufactured under strict GMP-aligned quality systems, ensuring consistent batch-to-batch performance for professional cosmetic and personal care brands worldwide. Our direct factory supply model delivers reliable bulk quantities with full technical documentation and free sample support.

Arbutin here is the beta-glucoside of hydroquinone, not Alpha-Arbutin. It is used in leave-on spot and tone care as a water-soluble active associated with tyrosinase pathways. The material is a white crystalline powder that dissolves in water.

Brightening serums continue to specify this INCI when the formula calls for beta-arbutin rather than the alpha isomer. Cosmetic-grade Arbutin is a practical bulk active when the COA states the isomer and the assay.

Product Specification

• INCI Name: Arbutin
• CAS No.: 497-76-7
• Molecular Formula: C₁₂H₁₆O₇
• Molecular Weight: 272.25 Da
• Appearance: White crystalline powder
• Purity: Typical ≥98%
• Solubility: Soluble in water
• Suggested pH: 5.0–7.0 in finished systems
• Storage: Store in a cool, dry place; protect from light and moisture

Key Benefits & Applications

Arbutin is the beta isomer used in spot-care and even-tone leave-on systems.

• Used in serums targeting localized discoloration
• Distinct from Alpha-Arbutin; specify the beta isomer on the COA
• Dissolves in the water phase of essences and gels
• Pairs with niacinamide in a tone-evening chassis
• Typical use level: 1.0–3.0% in leave-on formulations

Formulation Guidelines

Follow these guidelines to keep beta-Arbutin dissolved and away from high pH.

• Suggested Use Level: Typical 1.0–3.0% in the finished formula
• pH Range: Suggested 5.0–7.0
• Addition: Dissolve in the water phase during cool-down, below 40°C
• Stability: Protect from light; confirm the isomer assay on each batch
• Combine with Niacinamide when a second tone-evening active is needed in the same chassis.
