Glycerin (also called glycerol or glycerine) is an organic compound present in all natural lipids (fats). It usually comes in the form of a colourless, odourless, sweet-tasting liquid. Although it can be derived from tallow (animal fat), we only use glycerin from plant sources.

In our bodies, glycerin is naturally present in the skin and functions as a moisturiser, drawing moisture up through skin layers which slows or prevents excessive drying and evaporation. These moisture-retaining properties coupled with its mildness make it a particularly useful ingredient for people with sensitive skin. We use glycerin in many of our formulations as a humectant, which helps to increase the water content on the top layers of the skin, as well as preserve the moisture content of the product after production.

In toothpastes and oral care, glycerin can be used to help improve the smoothness and lubrication of the toothpaste, and to help protect teeth through its bacteriostatic action, which inhibits the reproduction of bacteria.
