Is Hamamelis Virginiana Leaf Extract COSMOS-approved?
It is generally permitted under COSMOS-natural and COSMOS-organic frameworks when sourced and extracted with approved materials. It fits Green Chemistry best when made from renewable plant material using low-concern solvents such as water, glycerin, or ethanol.
How does Hamamelis Virginiana Leaf Extract work chemically?
The molecule profile is not a single compound, but a water-soluble mixture rich in hydrolyzable tannins, flavonoids, phenolic acids, sugars, and other minor plant constituents. Typical use is often around 0.5% to 5%, and the polyphenol fraction can darken or shift odor with oxygen, light, high heat, or trace metals, so chelation and good preservation are common formulation supports.
