Vegetable Glycerin ●
TL;DR. This ingredient primarily acts as a humectant, helping bind water in the outer skin layers and reduce formula dry-down. It also serves as a water-phase solvent and texture modifier in creams, cleansers, serums, and oral care.
What does Vegetable Glycerin do in a cosmetic formula?
This ingredient primarily acts as a humectant, helping bind water in the outer skin layers and reduce formula dry-down. It also serves as a water-phase solvent and texture modifier in creams, cleansers, serums, and oral care.
Is Vegetable Glycerin clean?
This ingredient is broadly accepted in clean-beauty frameworks and is generally well tolerated, including by sensitive skin. Clean-standard concerns are usually about source transparency rather than the molecule itself.
Is Vegetable Glycerin sustainable?
This material is commonly plant-derived from oils such as palm, coconut, soy, or rapeseed, and it is readily biodegradable. The main sustainability question is agricultural sourcing, especially whether palm-linked supply is traceable or certified.
Is Vegetable Glycerin COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic standards when sourced and processed according to the standard. Its fit with Green Chemistry is strong because it can come from renewable feedstocks, is biodegradable, and has a long safety record in water-based formulations.
How does Vegetable Glycerin work chemically?
The molecule is a small three-carbon polyol with three hydroxyl groups, which explains its strong water-binding behavior and high compatibility with aqueous systems. Typical leave-on use is about 2 to 10 percent, with higher levels increasing tack, and it is stable across the usual cosmetic pH range.
