Glycerine is an exceptionally good moisturizing, emollient and protective agent. Its ability to capture and retain water slows down the evaporation of water from the surface of the skin. It is also a humectant (wetting agent), which promotes hydration of the skin. Light Liquid Paraffin and White Soft Paraffin exert an emollient effect by forming an occlusive film that reduces trans-epidermal water loss, thus helping to maintain normal skin humidity levels.
