ABSTRACT:
An elastic detergent bar of improved elevated temperature stability, so that it better maintains its shape on storage at temperatures somewhat higher than normal, includes an amphoteric synthetic organic detergent in mixture with an anionic synthetic organic detergent, gelatin, water and insoluble gas in very small bubble form distributed throughout the bar. The bars are substantially form-retaining during storage and although they wear away during use, substantially retain their initial forms and elasticities for major proportions of their useful lives. Compared to similar bars in which the insoluble gas, such as air, is not present, the invented bars are stable at higher storage temperatures, e.g., 5.degree. to 10.degree. C. higher, making them commercially much more acceptable. Additionally, the elastic detergent bars are resistant to breakage during shipment and use, exhibit less surface tackiness than similar control bars, are very easily molded to finely figured and detailed shapes and of course, because of their lower density, float. Also within the invention is a process for making the described products.
