EGCG (Epigallocatechin Gallate) — Bulk Raw Material

EGCG (Epigallocatechin Gallate) — Cosmetic & Nutraceutical Raw Material

EGCG (Epigallocatechin-3-gallate) is the principal bioactive catechin extracted from green tea (Camellia sinensis), supplied as high-purity bulk powder for cosmetic manufacturers, dietary supplement brands, and nutraceutical CDMOs. As the most extensively researched green tea polyphenol — with over 8,000 published studies — EGCG is a versatile active ingredient spanning antioxidant skincare, photoprotection, metabolic health, and anti-aging applications.

Why Manufacturers Source EGCG from Us

• Hot-water extraction + HPLC fractionation — solvent-free initial extraction yields a clean botanical profile; HPLC purification ensures ≥98% EGCG content
• Dual-market versatility — one ingredient powers both cosmetic antioxidant serums and metabolic health supplements
• Clinically validated — 200–800 mg/day oral dosing supported by human trials; 0.1–1.0% topical use level with demonstrated collagen protection
• pH-stabilized handling — processing guidance ensures EGCG stability across manufacturing pH conditions

Technical Profile for Formulators

• Mechanism: Polyphenolic antioxidant — direct ROS scavenging + Nrf2/ARE pathway activation + MMP inhibition (collagen protection)
• Solubility: Water-soluble at pH 3.0–5.0; solubility decreases in neutral-to-alkaline conditions
• Appearance: White to off-white crystalline powder
• Recommended use level: 0.1%–1.0% (topical cosmetic); 200–800 mg/day EGCG (oral supplement)
• pH: Optimal stability at pH 3.0–5.0; avoid alkaline formulations
• Temperature: Add at ≤ 40°C (cool-down phase)
• Synergists: Vitamin C (co-antioxidant), vitamin E (lipophilic complement), niacinamide (barrier support)
• Photoprotection note: EGCG absorbs UVB and reduces UV-induced MMP expression — ideal for day creams and sun care

Processing Cautions

• Oxidation-sensitive: Protect from air exposure; use airtight blending and nitrogen-flushed packaging
• Light-sensitive: Manufacturing areas with UV-filtered lighting recommended
• Metal ions: Avoid iron and copper contact (catalyze oxidation and cause discoloration)
