<br>Natural glycerine can be extracted either from animal fats (the usual source) or from vegetable oils. We offer the pure, vegetable oil-extracted glycerine. It makes water ?wetter?, allowing water to absorb into the skin more easily and keeps absorbing moisture from the atmosphere for long lasting hydration. Natural and totally non-toxic, glycerine is a superior choice over the problematic propylene and butylene glycols routinely used in cosmetics.
