Epigallocatechin Gallate (EGCG): Water-Soluble Catechin for Sensitive Skin Formulations and Aqueous Antioxidant Systems

Molecular Identity

• INCI Name: Epigallocatechin Gallate
• Molecular Formula: C₂₂H₁₈O₁₁
• Source: Extracted from green tea leaves (Camellia sinensis)

Functionality and Application Potential

Epigallocatechin Gallate (EGCG) is the predominant catechin in green tea and is widely used in water-based cosmetic formulations targeting oxidative stress, skin fatigue, and surface sensitivity. As a polyphenolic compound with high water solubility, it is ideal for use in toners, gels, micellar systems, and pre-serum hydrators.

• Antioxidant Activity: Helps neutralize reactive oxygen species in aqueous formulations
• Skin Sensitivity Support: Included in products designed for fatigued, urban-exposed or reactive skin
• Plant-Derived Identity: Extracted from natural sources for clean-label compatibility
• Compatible with Actives: Pairs well with niacinamide, allantoin, and betaine in sensitive care formulas

Common in facial mists, hydrating gels, after-sun tonics, and light emulsions for antioxidant defense. Supplied in bulk format for technical formulation and industrial manufacturing.

Recommended Usage

• Water-based serums and mists: 0.05–0.3%
• Sensitive skin emulsions: 0.1–0.5%
• After-shave and calming sprays: 0.05–0.2%

EGCG is water-soluble and should be added to the aqueous phase. Avoid prolonged high-temperature exposure. Recommended pH range: 4.5–6.5.
