The present invention relates to a water-soluble solid composition that produces a lubricating liquid when dissolved in water. The composition is preferably prepared by kneading particles of a solid, such as sodium polyacrylate, with water and one or more optional additives to form a mixture. This kneaded mixture is then molded or otherwise formed into a desired shape, preferably one that is easily held such as a lump, sphere, or rod. The shaped composition may also be provided with a partial cover of a water-insoluble material or other modified surface so that it may be held more securely. In use a dry portion of the solid composition can be held in the hand and applied to an area of moistened skin to apply a lubricating liquid without also applying the lubricating liquid to the hand. Similarly, a portion of the solid composition may be moistened and then rubbed on dry skin to apply a lubricating liquid to the skin.
