  • Patent number: 4554097
    Abstract: An elastic detergent product which may also be used by children as a toy or plaything while taking a bath, includes a mixture of anionic and amphoteric synthetic organic detergents, gelatin and water. The products are substantially form-retaining and although they wear away during use, substantially retain their initial forms and elasticities for major proportions of their useful lives. They are easily manufactured and during the manufacturing process are moldable to finely figured and detailed shapes. Because of their elasticity they are resistant to breakage during shipping and use and because of their contents of both synthetic anionic and amphoteric organic detergents they exhibit less surface tackiness than other elastic detergent products or bars in which similar proportions of gelatin and water are present.

  • Patent number: 4544493
    Abstract: A process for neutralizing an organic sulfuric or sulfonic detergent acid, e.g., lauryl sulfuric acid or mixture of such acids, in liquid state, with a liquid solution or slurry of neutralizing agent of a low moisture content is conducted in a wiped film neutralizing reactor wherein a film of the organic acid(s) and neutralizing agent(s) is formed on an internal wall of the reactor, which wall (with the film) is continuously wiped during the neutralization reaction by a wall scraper or a plurality of scrapers which also agitate the reactants, whereby there is produced a pumpable aqueous slurry, having a high concentration of the detergent salt solids which is above a gel region which prevents the concentration of such detergents made by other processes that produce lower detergent concentrations. During the reaction, which is usually preferably conducted under vacuum, the heat generated is removed, usually by evaporation of water, so as to maintain a desirable temperature for the neutralization.

  • Patent number: 4543204
    Abstract: A detergent laundry bar, based on sodium higher fatty alcohol sulfate, which is resistant to breakage on handling, includes sodium higher fatty alcohol sulfate in which the higher fatty alcohol is of about 10 to 18 carbon atoms, water soluble builder salt for the sodium higher fatty alcohol sulfate, water insoluble particulate material which may also possess building properties, water and a higher fatty acid of 10 to 18 carbon atoms, with the proportion of higher fatty acid being such as to aid in overcoming the tendency of such laundry bars to crack, chip and break on handling. The water soluble builder salt will normally include an inorganic phosphate builder salt, such as sodium tripolyphosphate, and the water insoluble particulate material will normally include calcium carbonate and/or bentonite, and/or talc, usually being constituted of two or three of such materials. Preferably a higher fatty acid alkanolamide and a higher fatty alcohol will also be present.
