Melrose Pure Vegetable Glycerine is a natural humectant that has emollient-like properties, which can soften and soothe the skin and helps the outer skin layer (the epidermis) to retain moisture. Vegetable glycerine is a clear, colourless, and odourless liquid with a sweet taste and has the consistency of a thick syrup. Glycerin can be used as an effective natural sweetener as it does not significantly elevate blood sugar levels.
