Question 1

What does Hypericum Perforatum Flower/Leaf/Stem Extract do in a cosmetic formula?

Accepted Answer

This ingredient is used as a botanical skin-conditioning extract, mainly to support soothing, antioxidant, and appearance-calming claims in creams, oils, serums, and after-sun products.

Question 2

Is Hypericum Perforatum Flower/Leaf/Stem Extract clean?

Accepted Answer

It is generally accepted in clean-beauty frameworks and is not a common restricted-list material, but it carries a yellow signal because certain plant pigments can be photosensitizing at higher exposure levels. As with many botanicals, individual sensitivity depends on extract strength, solvent system, and overall formula context.

Question 3

Is Hypericum Perforatum Flower/Leaf/Stem Extract sustainable?

Accepted Answer

This material is plant-derived, renewable, and expected to be biodegradable when extracted with simple solvents. Sustainability depends mostly on agricultural practices, wild-harvest controls, and whether the carrier is water, glycerin, ethanol, vegetable oil, or a petroleum-derived glycol.

Question 4

Is Hypericum Perforatum Flower/Leaf/Stem Extract COSMOS-approved?

Accepted Answer

It can be permitted under COSMOS-natural and COSMOS-organic when the plant source and extraction solvents meet the standard. Its Green Chemistry profile is strongest with renewable sourcing, biodegradable solvent systems, and low-energy extraction, and weaker when petrochemical carriers are used.

Question 5

How does Hypericum Perforatum Flower/Leaf/Stem Extract work chemically?

Accepted Answer

This compound is a complex botanical mixture containing flavonoids, phenolic acids, tannins, and red naphthodianthrone pigments, so performance and color vary by plant part, harvest, and extraction method. It is typically used at low levels in finished products, often below a few percent, and formulas should account for light sensitivity, color transfer, and oxidation of phenolic constituents.
