Camellia Sinensis Leaf Extract*[1][2][3] ●
TL;DR. This ingredient is primarily used as an antioxidant and skin-conditioning botanical extract. It also supports soothing, mild astringency, and protection of formulas from visible oxidative discoloration.
What does Camellia Sinensis Leaf Extract*[1][2][3] do in a cosmetic formula?
This ingredient is primarily used as an antioxidant and skin-conditioning botanical extract. It also supports soothing, mild astringency, and protection of formulas from visible oxidative discoloration.
Is Camellia Sinensis Leaf Extract*[1][2][3] clean?
From a clean-beauty perspective, this ingredient is generally well accepted and is not a common restricted-list concern. Sensitivity is uncommon, though extract quality, solvent system, and residual preservative package matter for very reactive skin.
Is Camellia Sinensis Leaf Extract*[1][2][3] sustainable?
This material comes from renewable it biomass and its polyphenol-rich components are expected to be readily biodegradable. Its sustainability profile depends mainly on agricultural practices, water use, and the extraction solvent system, with water, glycerin, or ethanol extracts being the cleaner options.
Is Camellia Sinensis Leaf Extract*[1][2][3] COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic when produced from approved plant material using allowed extraction solvents and processing aids. It aligns well with Green Chemistry when sourced from renewable cultivation and extracted with benign solvents such as water, glycerin, or ethanol.
How does Camellia Sinensis Leaf Extract*[1][2][3] work chemically?
The molecule profile is a complex mixture rather than a single compound, typically containing polyphenols, catechins, flavonoids, tannins, amino acids, and small amounts of caffeine depending on extraction. Typical use is often around 0.1% to 5%, and the polyphenol fraction is more stable in mildly acidic to neutral systems but can oxidize faster with high pH, heat, light, or metal ions.
