Glycerin

Glycerin is a natural ingredient in vegetable and animal fats and oils, which mainly consists of triglycerides (compound of glycerol with three fatty acids). In cosmetic products glycerin is used as a moisturising agent due to its hygroscopic (water-attracting) properties. Besides that, it helps with the distribution of O/W emulsions (oil-in-water-emulsions) and it smoothes and protects the skin.
