Question 1

What does -Glycerin: Nourishes do in a cosmetic formula?

Accepted Answer

This ingredient is primarily a humectant, meaning it binds water and helps keep skin and hair hydrated. It also improves product feel and can support barrier comfort in creams, cleansers, serums, and hair care.

Question 2

Is -Glycerin: Nourishes clean?

Accepted Answer

This ingredient is widely accepted in clean-beauty frameworks because it is well tolerated, non-sensitizing for most users, and not a common restricted-list concern. High levels can feel tacky or briefly sting compromised skin, but that is a formulation and skin-condition issue rather than a broad clean-standard concern.

Question 3

Is -Glycerin: Nourishes sustainable?

Accepted Answer

This material can be sourced from plant oils or produced synthetically, with plant-derived supply often linked to vegetable oil processing. It is readily biodegradable and has low environmental persistence when used in rinse-off or leave-on personal care.

Question 4

Is -Glycerin: Nourishes COSMOS-approved?

Accepted Answer

It is permitted under COSMOS-natural and COSMOS-organic when sourced and processed according to the standard. From a Green Chemistry perspective, it aligns well when made from renewable feedstocks, with good biodegradability and a long safety record in water-based formulations.

Question 5

How does -Glycerin: Nourishes work chemically?

Accepted Answer

The molecule is a small three-carbon triol with three hydroxyl groups, which explains its strong water-binding behavior and broad compatibility in aqueous systems. Typical use levels are about 2% to 10% for hydration and skin feel, sometimes higher in masks or treatment products, and it is stable across normal cosmetic pH ranges.
