Natural bar soap contains glycerin to moisturize the skin. Glycerin is a humectant that draws in water. This means that soap will become soggy if it is kept in a soap dish that allows water to collect around it, and unintended waste will result. Natural soaps should be kept on a high drainage soap mat that allows the soap to sit on a grooved drainage surface away from water. This will further minimize waste.
