Question 1

What does Nasturtium Officinale Leaf/Stem Extract do in a cosmetic formula?

Accepted Answer

This ingredient is used as a botanical skin-conditioning extract, mainly to add antioxidant and soothing support to water-based formulas. It is typically a secondary active rather than a structural emulsifier, preservative, or surfactant.

Question 2

Is Nasturtium Officinale Leaf/Stem Extract clean?

Accepted Answer

From a clean-beauty perspective, this ingredient is generally well accepted when made with standard cosmetic extraction solvents and properly preserved. As with many botanical extracts, trace natural aromatics and plant compounds can be a sensitivity factor for reactive skin.

Question 3

Is Nasturtium Officinale Leaf/Stem Extract sustainable?

Accepted Answer

This material is plant-derived and generally biodegradable, with a relatively favorable profile when sourced from responsibly managed agriculture. Its footprint depends mostly on farming practices, water use, extraction solvent, and preservation system.

Question 4

Is Nasturtium Officinale Leaf/Stem Extract COSMOS-approved?

Accepted Answer

It is generally compatible with COSMOS-natural and COSMOS-organic frameworks when produced from approved plant material using permitted solvents such as water, glycerin, or ethanol. It fits Green Chemistry principles reasonably well because it is renewable, biodegradable, and can be made with low-concern extraction systems.

Question 5

How does Nasturtium Officinale Leaf/Stem Extract work chemically?

Accepted Answer

The molecule profile is not a single compound, but a complex botanical mixture that may include polyphenols, flavonoids, glucosinolate-derived compounds, minerals, and water-soluble plant metabolites. Typical use is often in the 0.1% to 5% range, and formulators usually manage color, odor, oxidation, microbial preservation, and heat exposure during processing.
