Quercus Suber Bark Extract ●
TL;DR. This ingredient is primarily used as an antioxidant and skin-conditioning botanical extract. It can also add mild astringency, which is useful in products aimed at excess oil feel or visible pore refinement.
What does Quercus Suber Bark Extract do in a cosmetic formula?
This ingredient is primarily used as an antioxidant and skin-conditioning botanical extract. It can also add mild astringency, which is useful in products aimed at excess oil feel or visible pore refinement.
Is Quercus Suber Bark Extract clean?
This ingredient is generally compatible with clean-beauty frameworks because it is plant-derived and has no common restricted-list profile. The main watchpoint is the natural tannin and polyphenol content, which can feel drying or sensitizing for some reactive skin at higher use levels.
Is Quercus Suber Bark Extract sustainable?
This material is sourced from tree it and is typically tied to a renewable it-harvesting system rather than whole-tree removal. It is expected to be biodegradable, with sustainability depending on responsible forestry and the solvents used for extraction.
Is Quercus Suber Bark Extract COSMOS-approved?
It can be permitted under COSMOS-natural and COSMOS-organic standards when the botanical source, extraction method, and solvents meet the standard’s requirements. It aligns well with Green Chemistry when made from renewable it material using water, ethanol, glycerin, or other approved lower-impact extraction systems.
How does Quercus Suber Bark Extract work chemically?
This material is a complex botanical extract containing polyphenols, tannins, phenolic acids, and lipophilic it barrier constituents rather than a single defined molecule. It is commonly used at low supplier-guided levels, often around 0.1% to 2%, and polyphenol-rich extracts can darken or lose activity with high pH, light exposure, oxygen, or trace metal contamination.
