Question 1

What does Non-GMO Vegetable Glycerin do in a cosmetic formula?

Accepted Answer

It is primarily a humectant, pulling water into the outer skin layers to improve hydration. It also serves as a water-phase solvent and texture modifier in lotions, cleansers, serums, and gels.

Question 2

Is Non-GMO Vegetable Glycerin clean?

Accepted Answer

This ingredient is well-tolerated, low-irritation, and not a common allergen or clean-standard restricted material. At higher use levels it can feel sticky, which is a sensory issue rather than a safety concern.

Question 3

Is Non-GMO Vegetable Glycerin sustainable?

Accepted Answer

This material is usually made from plant oils and is often a co-product of soapmaking or biodiesel production. It is readily biodegradable, but feedstock traceability matters when palm, soy, or coconut supply chains are involved.

Question 4

Is Non-GMO Vegetable Glycerin COSMOS-approved?

Accepted Answer

It is permitted under COSMOS-natural and COSMOS-organic when the sourcing and processing meet the standard, including it inputs where relevant. It fits Green Chemistry well because it can come from renewable feedstocks, is readily biodegradable, and does not require aggressive chemistry in typical cosmetic use.

Question 5

How does Non-GMO Vegetable Glycerin work chemically?

Accepted Answer

The molecule is a small three-carbon triol with three hydroxyl groups, which makes it highly water-soluble, hygroscopic, and able to bind water through hydrogen bonding. It is commonly used around 2-10% for humectancy, can feel tacky at higher levels, is stable across typical cosmetic pH ranges, and can support preservation by lowering water activity at elevated concentrations.
