Epigallocatechin ●
TL;DR. This ingredient functions mainly as an antioxidant and skin-conditioning active, helping limit oxidative change in formulas and on the skin surface.
What does Epigallocatechin do in a cosmetic formula?
This ingredient functions mainly as an antioxidant and skin-conditioning active, helping limit oxidative change in formulas and on the skin surface.
Is Epigallocatechin clean?
This ingredient generally fits clean-beauty expectations when it is purified from botanical sources and preserved in a stable formula. It is usually well tolerated, though high-polyphenol materials can cause sensitivity for some users depending on concentration and formula context.
Is Epigallocatechin sustainable?
This material is commonly plant-derived, with sourcing tied to tea and other botanical supply chains. It is expected to be biodegradable, but its sustainability profile depends on agricultural practices, extraction solvent choices, and purification efficiency.
Is Epigallocatechin COSMOS-approved?
It can align with COSMOS-natural and COSMOS-organic when obtained through permitted botanical extraction and processing methods. From a Green Chemistry perspective, it scores best when sourced from renewable plant material using water, ethanol, or other lower-concern solvents.
How does Epigallocatechin work chemically?
The molecule is a flavan-3-ol polyphenol with multiple phenolic hydroxyl groups, which explains its reducing and radical-scavenging behavior. It is prone to oxidation, especially with heat, light, oxygen, and higher pH, so formulators often use airtight packaging, chelators, and mildly acidic systems to improve stability.
