  • Patent number: 4619774
    Abstract: A fabric softening heavy duty liquid detergent, useful for both cleaning and softening laundry, includes certain proportions of sodium linear higher alkylbenzene sulfonate, sodium alkyl polyethoxy sulfate, builder salt (highly preferably a mixture of sodium tripolyphosphate and sodium carbonate), finely divided swelling bentonite and water. Such product is a stable pourable liquid, convenient for use in washing machines, for hand washing of laundry and for pre-treatment of badly soiled portions of items to be laundered. Preferably, the liquid detergent comprises about 9% of sodium linear tridecylbenzene sulfonate, about 2% of sodium alkyl polyethoxy sulfate wherein the alkyl is of 12 to 15 carbon atoms and the polyethoxy is of 3 ethylene oxide groups, 10 to 17% of sodium tripolyphosphate, e.g., 12% and 15%, 2 to 6% of sodium carbonate, e.g., 2% and 6%, about 12% of Wyoming bentonite, and 55 to 65% of water.

  • Patent number: 4604280
    Abstract: A method for stabilizing a cosmetic composition containing carrageenan, specifically, a toothpaste, wherein microwave radiation, preferably in the 0.8 to 3 gigahertz frequency range, is directed onto the toothpaste so as to raise its temperature to at least the gel-sol transition temperature of the carrageenan, after which the toothpaste is quiescently cooled to room temperature. The use of microwave radiation facilitates an even heating of the toothpaste, so that temperature sensitive components thereof are not adversely affected, and promotes excellent control of temperature regulation. Heating of the dentifrice, with improved thickening and stabilization thereof, is obtainable by passing it through a conduit while directing microwave radiation onto it and then filling it into suitable dispensing containers, or by filling the dentifrice into such containers and then subjecting them to microwave radiation.

  • Patent number: 3940220
    Abstract: Variegated detergent bars are made by mixing together pieces of soaps of contrasting colors in a vacuum zone and plodding the mixture in such manner as to fuse the different soaps together but maintain colors separate, thereby producing a desired pattern therein, preferably resembling marble. The pattern is controllable by variations of the proportions of material charged, plasticities thereof, speeds of the worms, design of the compression-extrusion head and preferably, by extruding the soaps through small openings in a plate after the final plodder worm, cutting the extrudates and imparting transverse or radial motions to them before final extrusion.Also described are plodding and extruding apparatuses utilized to practice the variegating process.
