Diglucosyl Gallic Acid

Product Description

Our high-purity Diglucosyl Gallic Acid (DGA) is manufactured under ISO-aligned biotech or synthesis controls with batch COA traceability, supplying cosmetic formulators direct factory pricing and flexible kilogram-to-tonne bulk volumes.

This water-soluble gallic acid diglucoside is enzymatically activated by skin microbiota to release gallic acid—modulating tyrosinase-linked melanin pathways, scavenging reactive oxygen species, and calming inflammatory signaling in brightening and sensitive-skin serums.

Unlike hydroquinone or high-irritation organic acids, this CosIng-listed DGA suits microbiome-friendly brightening portfolios where formulators want HPLC-verified assay, low irritation profiles, and direct factory supply.

Key Benefits & Applications

Diglucosyl Gallic Acid supports microbiome-friendly brightening, antioxidant, and tone-evening claims through microbiota-activated gallic acid release suited to sensitive-skin formulators.

• Tyrosinase Inhibition: Microbiota-released gallic acid helps modulate tyrosinase-linked melanin synthesis in brightening serums and essences.
• Whitening & Brightening: Supports radiance and tone-uniformity claims in clean-label daily brightening product lines.
• Even Skin Tone: Promotes uniform complexion appearance in tone-balancing emulsions and lightweight toners.
• Microbiome Balance: Microbiota-activated mechanism supports skin flora–friendly brightening in prebiotic-postbiotic complex care.
• Antioxidant Protection: Gallic acid moiety scavenges reactive oxygen species in daytime antioxidant brightening formulas.
• Anti-Inflammatory Modulation: Calms visible redness in sensitive-skin brightening and post-blemish recovery care.

Formulation Guidelines

Dissolve DGA in the aqueous phase; confirm assay, pH, and preservative adequacy for water-rich brightening bases.

• Recommended use level: 0.5–2% w/w in serums and emulsions; 0.5–1.5% in sensitive-skin toners (Typical).
• Optimal formula pH: Maintain 4.0–7.0; best stability and microbiota activation in mildly acidic systems (Typical).
• Processing: Add below 40°C to water or glycerin phase; pre-dissolve for clear essence formats.
• Compatibility: Works with niacinamide and prebiotics; avoid strong oxidizers that may degrade gallic acid moieties.
• Caution: Efficacy depends on skin microbiota activity—validate claims with appropriate testing protocols.
• Synergy: Pair Niacinamide at 2–5% with diglucosyl gallic acid in microbiome-friendly brightening essences for dual-pathway tone control.
