Glycerine is a humectant, which means it has the property of attracting water to itself. It is a moisturizer that can attract water from the deeper skin layers or even the air to moisturize the outer layer of your skin. Bottom line – It is a moisturizer that actually attracts more moisture and helps slow the evaporation of water from your skin.
Glycerine is a natural by-product of the soap-making process, which means all handmade soaps have glycerine in them. Unfortunately, many commercial brands strip the glycerine from their soap and sell it off to be used in other lotions and moisturizers. This is why handmade soaps are more moisturizing and better for your skin. In fact, our soaps are so high in glycerine that occasionally you can actually see it in the soap. It will create a marble effect in the appearance of the soap and is clear or transparent. We call this clear marbling “glycerine rivers”. If you receive a soap with glycerine rivers, consider yourself lucky!
