Abstract
A water-soluble polyamide or polyester is prepared or melted in the presence of a surface active agent. The polyamide or polyester is present in an amount of 5 to 95 wt % with the surfactant as the major portion of the balance. The composition is molded or shaped into long lasting detergent bars. In the specified range, compositions with more surface active agent are more suitable for detergent bars. Compositions with more polymer are more suitable for toys or shaped or molded articles.
