TL;DR. This ingredient is primarily used as an antioxidant botanical extract, helping protect formulas and skin from oxidation-related stress. It can also add mild soothing and astringent benefits depending on extract strength.
What does C. Sinensis Leaf Extract do in a cosmetic formula?
This ingredient is primarily used as an antioxidant botanical extract, helping protect formulas and skin from oxidation-related stress. It can also add mild soothing and astringent benefits depending on extract strength.
Is C. Sinensis Leaf Extract clean?
This ingredient is generally well accepted in clean-beauty standards and is usually low concern for irritation at typical cosmetic levels. As with many botanicals, quality depends on solvent choice, preservation system, and control of agricultural residues.
Is C. Sinensis Leaf Extract sustainable?
This material is plant-derived and based on a renewable agricultural feedstock, with good expected biodegradability. Sustainability depends on farming practices, residue management, water use, and whether the extract is made with water, glycerin, or ethanol rather than less preferred solvents.
Is C. Sinensis Leaf Extract COSMOS-approved?
It is permitted under COSMOS-natural and can be COSMOS-organic when the agricultural source and extraction process meet the standard. It aligns well with Green Chemistry when produced from renewable material using approved, lower-impact solvents and simple extraction steps.
How does C. Sinensis Leaf Extract work chemically?
This compound is a complex botanical mixture rich in polyphenols, including catechins, flavonoids, tannins, and small amounts of caffeine, rather than a single defined molecule. Typical use is often around 0.1% to 5% depending on extract concentration, and its polyphenols are more stable in mildly acidic to neutral systems, with light, oxygen, high pH, and metal ions increasing oxidation risk.
