A sponge including an elastic material having a lipid, such as an oil, a fat, or a combination thereof, integrally formed therewith. The elastic material includes an amount from between 0.5 to 20 parts by weight of the lipid, and the lipid is selected from the group consisting of esters of fatty acids, alkanes, squalane and derivatives thereof squalene, bisabolol, animal hair oils and fats, wax, lanolin and combinations thereof to provide the sponge with a gentle feel. The sponge may also be made by first foam molding the sponge from an elastic material, impregnating the sponge with a water-dispersed lipid and allowing the sponge to dry for a predetermined amount of time so that the lipid is substantially inseparable from the elastic material.
