EGCG stands for Epigallocatechin Gallate. It is one of the main naturally occurring catechins (polyphenols) found in green tea (Camellia sinensis), especially in green tea extract. EGCG is a powerful polyphenolic antioxidant. It is responsible for much of the antioxidant activity associated with green tea.
EGCG in cosmetics: For a serum, cream, lotion, or eye product, EGCG can be used as an antioxidant active. However, it is relatively unstable, particularly when exposed to oxygen, light, heat and higher pH.
Important: EGCG is not the same as ordinary green tea powder or green tea extract. A product labeled, for example, EGCG 90–98% is a much more concentrated active.
Application Purpose
Skincare: Antioxidant and helps protect skin from oxidative stress
Anti-aging formulations: Supports formulations aimed at reducing the appearance of environmental/oxidative damage
Acne/oily-skin products: Commonly researched for sebum and blemish-related applications
Brightening products: Used in formulations targeting uneven-looking skin tone
Hair/scalp products: Used in antioxidant and scalp-care formulations
Dietary supplements: Used as a concentrated green-tea polyphenol
Functional foods/beverages: Added as a source of green-tea catechins
Antioxidant formulations: Helps protect formulations and biological systems from oxidative stress
Epigallocatechin Gallate EGCG
For a cosmetic formulation, generally recommend use is : 0.1–1%
EGCG as a starting formulation range, depending on the raw material purity and supplier specification.
Keep the formulation around slightly acidic pH where appropriate.
Use airless/opaque packaging.
Minimize oxygen exposure.
Consider a suitable chelator and antioxidant system.
