Accepted Answer

This ingredient is plant-derived and expected to be biodegradable, with sustainability depending on responsible harvesting and extraction practices. Bark-derived components especially benefit from supplier controls that document sourcing and regeneration practices.

Question 4

Is Amurense Bark/Polygonum Cuspidatum COSMOS-approved?

Accepted Answer

It can align with COSMOS-natural and COSMOS-organic when the plant material and extraction solvents meet the standard’s rules. From a Green Chemistry lens, it fits best when made with water, ethanol, glycerin, or other approved benign solvents and sourced through documented plant supply chains.

Question 5

How does Amurense Bark/Polygonum Cuspidatum work chemically?

Accepted Answer

This material is a complex botanical mixture that may contain polyphenols and alkaloid-type compounds, so activity and color can vary by harvest, plant part, and extraction method. It is usually used at low cosmetic active levels in leave-on products, and formulators typically protect it from excessive heat, light, and incompatible pH conditions to preserve extract quality.
