Epigallocatechin Gallate (EGCG) is the most abundant and potent catechin found in Green Tea (Camellia sinensis). It is a phenomenal multi-functional active renowned for its extraordinarily high antioxidant capacity, offering superior defense against UV and environmental damage. EGCG also exhibits powerful anti-inflammatory, oil-regulating, and collagen-protective effects, making it a versatile ingredient for anti-aging, acne, and sensitive skin formulations.

|---|---|
| CAS No. | 970-74-1 |
| Source | Green Tea (Camellia sinensis) Leaf Extract |
| Appearance | White to light brown powder |
| Core Function | Antioxidant, Anti-inflammatory, Sebum Regulation, UV Damage Mitigation, Collagen Preservation |
EGCG is recognized as one of the most clinically relevant molecules in botanical skincare, with its antioxidant power far exceeding that of many traditional vitamins. The strong consumer demand for effective, naturally derived “superfoods” and “clean beauty” actives firmly establishes EGCG as a premium ingredient in formulations targeting skin defense, visible inflammation, and sebum control.
Extreme Antioxidant: Possesses a highly reactive chemical structure that efficiently and rapidly scavenges various free radicals and Reactive Oxygen Species (ROS).
Anti-Inflammatory Cascades: Directly inhibits several inflammatory enzymes (like COX-2 and LOX) and suppresses pro-inflammatory signaling pathways (like NF–kB), effectively calming redness and irritation.
Sebum Control: Shows promise in reducing sebum excretion by targeting the androgen receptor pathway in sebocytes, making it excellent for oily and acne-prone skin.
Photoprotection: Mitigates the immunosuppressive and damaging effects of $text{UV}$ radiation on skin cells, protecting cellular DNA and structure.
| Parameter | Specification (High Purity Grade) |
| Purity | ≥90% (HPLC) |
| Molecular Weight | 458.37 g/mol |
| Recommended Dosage | 0.5%-3.0% (as standardized extract) |
| Solubility | Water soluble (requires specific formulation for optimal stability) |
| Stability | Highly unstable (sensitive to high pH, heat, and oxidation) |
| Storage | Cool, dark, dry, inert atmosphere preferred for powder |
Scientifically Proven Potency: Backed by substantial clinical research confirming its efficacy across multiple skin concerns (acne, aging, sun damage).
Aesthetic Benefits: Provides visible calming and reduction in redness, offering instant gratification to users with irritated skin.
Holistic Skin Solution: Addresses the root causes of both aging (oxidation) and acne (inflammation and sebum), offering broad market appeal.
Natural Origin: Derived from one of the most trusted and globally recognized botanical sources (Green Tea).
Integration Phase: EGCG is water soluble. It must be dissolved in the aqueous phase. To maximize stability, it should be added in the cooling phase (below 40°C).
Concentration: Usage ranges from 0.5% to 3.0% of the high-purity powder/standardized extract for functional claims.
Stability Management: EGCG is highly prone to oxidation, especially at a high pH (above 7.0). Optimal formulation pH is typically slightly acidic (4.0 – 6.0). Co-antioxidants like Vitamin C derivatives or Ferulic Acid are crucial stabilizers.
Aesthetics: The powder can impart a light brownish color to the final product.

Technical Dossier (Certificate of Analysis – COA, Technical Data Sheet – TDS, Material Safety Data Sheet – MSDS)
Acne & Oily Skin Serums: Targeted formulas for sebum control, pore refinement, and anti-inflammation.
Daily Antioxidant Protection: Serums and creams for morning use to fight environmental damage.
Soothing & Redness Relief: Treatments for sensitive, compromised, or irritated skin.
Anti-Photoaging Formulas: Products designed to mitigate the cumulative effects of UV exposure.
Anti-Inflammatory Power: Extensive studies show EGCG‘s efficacy in suppressing inflammatory signaling molecules relevant to acne, rosacea, and general skin irritation.
Sebocyte Control: Research confirms its ability to reduce the size and lipid production of sebaceous glands, a key factor in controlling oily skin.
DNA Protection: In-vitro data supports its protective effect on skin cell DNA against UV induced damage, highlighting its photoprotective role.
A: EGCG is highly susceptible to oxidation in water, especially at neutral or high pH. Stability is best achieved by formulating in slightly acidic pH, using specialized delivery systems (e.g., liposomes), and combining it with synergistic antioxidants like Ferulic Acid.
A: No. EGCG is the specific, single most potent catechin within Green Tea Extract. Sourcing pure, standardized EGCG powder ensures superior potency and reliable results compared to using a non-standardized raw leaf extract.
A: No. EGCG is photoprotective. When used topically before sun exposure (underneath sunscreen), it is highly effective at reducing the oxidative damage caused by UV light. It should be used daily for its defense benefits.
