Abstract
Abstract An elastic detergent bar, useful as a functional article and bath plaything, includes a synthetic organic detergent, which is either an anionic detergent or an amphoteric detergent, gelatin and water. When the synthetic anionic detergent is employed a cross-linking or denaturing agent for the gelatin is also present. The articles made, in bar or cake form, are useful detergents and substantially form-retaining.Although they wear away somewhat during use they retain their general shapes and elasticities for major proportions of their useful lives. They are easily manufactured and molded or otherwise shaped to final form, are moldable to finely figured and detailed shapes and are resistant to breakage during shipping and use.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
198 words
A hand squeezable, elastic, solid molded detergent product comprising about 10 to 80% of a synthetic organic detergent selected from the group consisting of anionic sulfated and sulfonated synthetic organic detergents and amphoteric synthetic organic detergents, said anionic sulfated and sulfonated synthetic organic detergents being water soluble and selected from the group consisting of alkali metal, triethanolamine and ammonium linear higher alkylbenzene sulfonates, paraffin sulfonates, olefin sulfonates, higher fatty alcohol sulfates, monoglyceride sulfates and higher fatty alcohol polyethylene glycol sulfates and mixtures thereof and the amphoteric detergent being water soluble and selected from the group consisting of betaaminopropionates, betaiminodipropionates and imidazolium salts and mixtures thereof, about 5 to 30% of gelatin, about 5 to 60% of water and about 1 to 5% of a compound selected from the group consisting of cross-linking agents and denaturing agents for the gelatin and mixtures thereof when the synthetic organic detergent is an anionic detergent, which product is sufficiently squeezable and elastic so that a 2 cm. thickness thereof can be pressed between a thumb and forefinger to a 1 cm. thickness and upon release of such pressure will return within five seconds to within 1 mm. of the 2 cm. thickness.
Claim 2
Dependent Claim
198 words
A hand squeezable, elastic, solid molded detergent product comprising about 10 to 80% of a synthetic organic detergent selected from the group consisting of anionic sulfated and sulfonated synthetic organic detergents and amphoteric synthetic organic detergents, said anionic sulfated and sulfonated synthetic organic detergents being water soluble and selected from the group consisting of alkali metal, triethanolamine and ammonium linear higher alkylbenzene sulfonates, paraffin sulfonates, olefin sulfonates, higher fatty alcohol sulfates, monoglyceride sulfates and higher fatty alcohol polyethylene glycol sulfates and mixtures thereof and the amphoteric detergent being water soluble and selected from the group consisting of betaaminopropionates, betaiminodipropionates and imidazolium salts and mixtures thereof, about 5 to 30% of gelatin, about 5 to 60% of water and about 1 to 5% of a compound selected from the group consisting of cross-linking agents and denaturing agents for the gelatin and mixtures thereof when the synthetic organic detergent is an anionic detergent, which product is sufficiently squeezable and elastic so that a 2 cm. thickness thereof can be pressed between a thumb and forefinger to a 1 cm. thickness and upon release of such pressure will return within five seconds to within 1 mm. of the 2 cm. thickness.
Claim 3
Dependent Claim
