Preparation.—Take neutral cocoanut-oil-soda soap (or tallow-soda soap), 1 part; glycerin (sp. gr., 1.250), 4 parts. The soap must be exactly neutral and dried at 100° C. (212° F.). Dissolve the soap in the glycerin on a water-bath, and while still hot filter the solution.
Description and Uses.—This process yields a hygroscopic, odorless, light-yellow mass, having elasticity. The heat of the body is sufficient to liquefy it. This has been proposed by Hebra as an ointment base, the desired medicinal agents being added to it (Proc. Amer. Pharm. Assoc., 1891).
