Question 1

What does Stevia Rebaudiana Leaf/Stem Extract do in a cosmetic formula?

Accepted Answer

This ingredient is used mainly as a botanical skin-conditioning extract, with secondary antioxidant and soothing support depending on the extract composition. In lip and oral-care products, it can also contribute a naturally sweet taste profile.

Question 2

Is Stevia Rebaudiana Leaf/Stem Extract clean?

Accepted Answer

From a clean-beauty perspective, this ingredient is generally well tolerated and does not have notable restricted-list friction. As with many botanical extracts, sensitivity is possible for a small subset of users, especially in concentrated or poorly preserved formats.

Question 3

Is Stevia Rebaudiana Leaf/Stem Extract sustainable?

Accepted Answer

This material is plant-derived, renewable, and typically supplied in water, glycerin, or alcohol-based extracts. It is expected to be readily biodegradable, with the main sustainability variables being agricultural practices, solvent choice, and extract standardization.

Question 4

Is Stevia Rebaudiana Leaf/Stem Extract COSMOS-approved?

Accepted Answer

This ingredient is generally compatible with COSMOS-natural standards when made using approved extraction methods and solvents. It can fit COSMOS-organic positioning when the agricultural source is certified organic, and it aligns well with Green Chemistry when produced through simple aqueous, glycerin, or ethanol extraction.

Question 5

How does Stevia Rebaudiana Leaf/Stem Extract work chemically?

Accepted Answer

This extract contains a mixture of polar plant compounds, including sweet diterpene glycosides and phenolic constituents, rather than a single purified molecule. Typical cosmetic use is often in the low range, around 0.1% to 2% for leave-on products, with stability influenced by solvent system, preservation, pH, color, and odor management.
