Abstract
An elastic detergent bar of improved form-retaining ability during elevated temperature storage and of improved foaming power after use comprises an organic detergent which is an ammonium or lower alkanolammonium anionic organic detergent salt or a mixture of such anionic detergent with amphoteric synthetic organic detergent, gelatin and a lower di- or polyhydric alcohol. The bars made, which are essentially free of water, are of improved thermal stability, allowing them to be stored at higher temperatures than comparable bars, without distortion, and do not readily form inhibiting gel structures or coatings after use, which could otherwise diminish foaming power. Also within the invention is a method of making the described detergent bars.
Claims11
A hand squeezable, elastic, solid molded detergent product of improved form retaining ability and foaming power after use which is initially substantially anhydrous, and consists essentially of about 10 to 70% of an organic detergent selected from the group consisting of ammonium and lower alkanolammonium anionic organic detergent salts of detergent acids and mixtures of such anionic organic detergent salt(s) and amphoteric synthetic organic detergent(s), about 8 to 35% of gelatin and about 20 to 65% of a lower pluralhydric alcohol selected from the group consisting of lower di- and polyhydric alcohols and mixtures thereof, said anionic organic detergent acids being selected from the group consisting of higher fatty alcohol sulfuric acids, higher fatty acid monoglyceride sulfuric acids, higher alkylbenzene sulfonic acids, paraffin sulfonic acids, olefin sulfonic acids, higher fatty alcohol polyethylene oxide sulfuric acids, higher fatty alcohol polyethylene oxide sulfonic acids, alkylphenol polyethylene oxide sulfuric acids, alkylphenol polyethylene oxide sulfonic acids and higher fatty acids and mixtures thereof and the amphoteric synthetic organic detergent being selected from the group consisting of imidazolinium betaines, iminodipropionates and aminopropionates and mixtures thereof, which 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.
