Epigallocatechin Gallate, commonly abbreviated as EGCG, is a naturally occurring polyphenolic compound belonging to the catechin family. It is a gallate ester of epigallocatechin and is one of the characteristic polyphenolic constituents associated with green tea.
Epigallocatechin Gallate has the CAS Number 989-51-5, molecular formula C₂₂H₁₈O₁₁, and molecular weight 458.4 g/mol. It is also known as (-)-Epigallocatechin Gallate, EGCG, and Epigallocatechin-3-gallate.
EGCG belongs to the polyphenol and gallate ester classes and contains multiple hydroxyl groups within its molecular structure. Its physicochemical characteristics make it a specialty ingredient for formulation development.
In cosmetic formulation development, Epigallocatechin Gallate can be evaluated for skincare products where antioxidant and skin-conditioning properties are desired. Potential product formats include facial serums, creams, lotions, masks and other specialty personal-care formulations.
EGCG has limited stability under certain formulation conditions, so formulators should carefully evaluate pH, temperature, oxygen exposure, light exposure, packaging and compatibility with other ingredients.

Epigallocatechin Gallate is a catechin-derived polyphenol and gallate ester. It is also called EGCG or epigallocatechin-3-gallate.
The chemical identity of EGCG is associated with CAS 989-51-5. Its molecular formula is C₂₂H₁₈O₁₁, and its molecular weight is 458.4 g/mol.
EGCG should be distinguished from epigallocatechin, which has a different molecular formula, CAS number and molecular weight. Epigallocatechin is C₁₅H₁₄O₇, CAS 970-74-1, with molecular weight 306.27 g/mol.
Important technical information includes:
Important: If the SDP product is purified EGCG rather than a Camellia sinensis extract, the CMS INCI field should be matched to the actual commercial ingredient identity and regulatory documentation, rather than automatically using a plant-extract INCI name.
EGCG can be evaluated as a specialty cosmetic ingredient in formulations focused on antioxidant and skin-conditioning properties.
Potential applications include:
The appropriate concentration should be established according to the actual product grade, formulation requirements and applicable cosmetic regulations.
Epigallocatechin Gallate can be evaluated in suitable facial serum formulations.
Potential formats include:
Formulators should evaluate EGCG stability during formulation development, particularly with respect to pH, oxygen, light, temperature and interaction with other ingredients.
EGCG can also be evaluated in compatible cream and lotion systems.
Potential applications include:
Finished formulations should be evaluated for color, uniformity, stability, active distribution and compatibility.
Important formulation considerations include:
Because EGCG is a polyphenolic compound, formulation developers should evaluate oxidative stability and color changes during development.
