Question 1

What does Leonurus Sibiricus Flower/Leaf/Stem Extract do in a cosmetic formula?

Accepted Answer

It is used as a botanical skin-conditioning extract, mainly to support antioxidant, soothing, and calming claims in leave-on and rinse-off products. It contributes minor bioactive character rather than structure, cleansing, or preservation.

Question 2

Is Leonurus Sibiricus Flower/Leaf/Stem Extract clean?

Accepted Answer

Clean-beauty frameworks generally view this ingredient as a low-concern botanical extract, with no common restricted-list flag. As with many plant extracts, batch composition and trace fragrance allergens depend on source, extraction solvent, and final use level.

Question 3

Is Leonurus Sibiricus Flower/Leaf/Stem Extract sustainable?

Accepted Answer

This material is plant-derived and expected to be biodegradable in typical cosmetic use. Its footprint depends on agricultural practices, harvest controls, extraction solvent, and whether the supplier uses water, glycerin, or alcohol-based extraction.

Question 4

Is Leonurus Sibiricus Flower/Leaf/Stem Extract COSMOS-approved?

Accepted Answer

It is generally compatible with COSMOS-natural and COSMOS-organic when the plant material and extraction system meet approved sourcing and processing rules. It fits Green Chemistry best when made with renewable solvents such as water, glycerin, or ethanol and managed as a readily biodegradable extract.

Question 5

How does Leonurus Sibiricus Flower/Leaf/Stem Extract work chemically?

Accepted Answer

This material is a complex botanical mixture rich in polar phenolics, flavonoids, and other secondary metabolites rather than a single molecule. It is commonly used at low percentages, often around 0.1% to 5% as supplied, with stability driven by the carrier, preservation system, pH, and gradual oxidation that can shift color or odor over time.
