A colourless sweet viscous liquid derived from vegetable fats. It is a by-product of the soap-making process, which separates the glycerin from the fatty acids in the whole oil. In this case, the glycerin is extracted from non-palm sources.
Glycerin is a humectant or water-binding additive. It performs a number of functions in a formula including increasing solubility of some actives (herbal extracts, perfumes etc), acting as a moisture reservoir to prevent a product from drying out and/ or as a cost-effective skin conditioning agent.
It is often said that glycerin is a natural preservative. This is a slight over-simplification as while glycerin is self-preserving it is not a preservative. Glycerin works by keeping water bound up in a formula making it unavailable for microbes and if microbes have no water they can't thrive. To achieve this glycerin has to be at a high level, usually higher than the average cosmetic formula can bare thus making this an impractical way to keep a product preserved.
Use level: 1-5% is typical
Solubility: Water-soluble.
