The Chemistry Behind Vegetable Glycerin
Vegetable Glycerin is a polyhydric alcohol, also known as a sugar alcohol, and is naturally present in all fats, oils, and phospholipids. In skincare, it behaves as a humectant, pulling moisture into the skin’s intercellular spaces, improving hydration, and protecting the lipids of skin cells. Glycerin’s ability to dissolve a wide variety of water-insoluble ingredients makes it a common solvent in both cosmetic and herbal formulations. Produced via the hydrolysis of fats and the fermentation of sugars, Vegetable Glycerin is free of animal-derived components, making it a 100% vegan option.
