Question 1

What does Aspalathus Linearis Leaf/Stalk Extract do in a cosmetic formula?

Accepted Answer

This ingredient is used as a botanical antioxidant and skin-conditioning extract, mainly to help support formulas aimed at soothing, redness-prone, or environmentally stressed skin. It can also contribute a light natural color depending on extraction and concentration.

Question 2

Is Aspalathus Linearis Leaf/Stalk Extract clean?

Accepted Answer

From a clean beauty perspective, this ingredient is generally well-tolerated and not a common restricted-list concern. The main quality questions are the extraction solvent, residual solvent control, and any preservatives added to the supplied extract.

Question 3

Is Aspalathus Linearis Leaf/Stalk Extract sustainable?

Accepted Answer

This material is plant-derived and typically sourced from cultivated leaf and stalk material, with a low persistence profile once diluted and rinsed away. Supply-chain quality depends on responsible farming, water management, and fair sourcing from its limited growing region.

Question 4

Is Aspalathus Linearis Leaf/Stalk Extract COSMOS-approved?

Accepted Answer

It is permitted under COSMOS-natural and COSMOS-organic when made with approved extraction solvents and compliant preservatives or carriers. It aligns well with Green Chemistry when produced through water, glycerin, ethanol, or other lower-impact extraction systems and handled with minimal processing.

Question 5

How does Aspalathus Linearis Leaf/Stalk Extract work chemically?

Accepted Answer

The molecule profile is a complex mixture rather than a single compound, rich in polyphenols such as C-glycosyl flavonoids, flavonols, and phenolic acids. Typical use levels for liquid cosmetic extracts are often about 0.1% to 5%, and the color and antioxidant profile can shift with high pH, heat, light, and repeated air exposure.
