Glycerin Oil
Glycerin is a sweet-tasting colorless thick liquid. Glycerin can be dissolved in water or alcohol, but not oils. But many things can be dissolved into glycerin, so it is a good solvent. Glycerin absorbs water from the air. So 100% pure glycerin placed on the skin would be dehydrating, but when mixed with water, glycerin softens the skin. Some people say this softening is the result of the glycerin attracting moisture to your skin. But others say the glycerin has some other properties which are helpful to the skin. But either way, the bottom line is that glycerin does soften the skin.
