Abstract: A stabilized built single-phase enzyme-containing liquid detergent composition is provided comprising:(a) from about 8 to 20%, by weight, of one or more surface active anionic detergent compounds;(b) from about 5 to 25%, by weight, of a water-soluble non-phosphate detergent builder salt;(c) an effective amount of an enzyme or enzyme mixture selected from the group consisting of alkaline protease enzymes and alpha-amylase enzymes;(d) an enzyme stabilizing system containing, based on the weight of the detergent composition, (i) from about 12 to 25% of propylene glycol and (ii) from about 1 to 5% of a boron compound selected from the group consisting of boric acid, boric oxide and alkali metal borates; and(e) from about 25 to 75%, by weight, water.
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.

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.
Abstract: A concentrated aqueous single-phase built liquid detergent composition is provided comprising:(a) from about 15 to 18%, by weight of a water-soluble non-phosphate detergent builder salt;(b) from about 15 to 23%, by weight, of a surface active nonionic detergent compound which is the condensation product of 5 to 9 moles of ethylene oxide with one mole of an aliphatic alcohol containing 12 to 15 carbon atoms;(c) from about 1 to 6%, by weight of at least one amphoteric detergent compound selected from among a group of described betaine detergent compounds;(d) from about 5 to 8%, by weight, of a solubilizer consisting essentially of an alkali metal salt of octyl phosphonate; and(e) from about 35 to 65%, by weight, water.
Abstract: Anhydrous dentifrice having desirable rheological, sensory and hygienic characteristics containing a polysaccharide gum and glycerine humectant. Ingredients at least partially incompatible when water is present, such as zeolite or molecular sieve, may be included. The polysaccharide is clarified or non-clarified deacetylated heteropolysaccharide S-60.
Abstract: Gel dentifrice of desirable consistency having a low water content and a hydrous silica gel polishing agent and an antinucleating agent containing at least one phosphonic group. Optimum consistency is attained by incorporating the antinucleating agent into a gel phase containing humectant and gelling agent prior to incorporation of the polishing agent therein.
Abstract: A non-antibacterial oral composition effective to promote oral hygiene containing tranexamic acid as antigingivitis agent and an additive which reduces staining of dental surfaces caused by said agent without substantially diminishing the antigingivitis activity of said agent. The antistain additive is a peroxydiphosphate salt, preferably tetrapotassium peroxydiphosphate (K.sub.4 P.sub.2 O.sub.8).
Abstract: A periodontal dental preparation is disclosed comprising folic acid, a dentally acceptable water-insoluble polishing agent which reduces the soluble folic acid present in the preparation and a fluorine-containing agent which increases retention of soluble folic acid in said preparation, the fluorine-containing agent comprising an alkali metal fluoride, and alkali metal monofluorophosphate, or a mixture thereof.
Abstract: An antibacterial oral composition effective to promote oral hygiene containing a quaternary ammonium antibacterial antiplaque agent and an additive which reduces staining of dental surfaces without substantially diminishing the antibacterial and antiplaque activity of the agent. Benzethonium chloride and cetyl pyridinium chloride, are typical examples of such antibacterial agents. The antistain additive is mellitic acid, 1,2,3,4,5,6-hexahydromellitic acid and/or an orally acceptable salt thereof.
Abstract: Laundry detergent compositions containing halloysite, kyanite or mixtures of these with each other or with metakaolin or bentonite. Compositions preferably contain a quaternary ammonium fabric softener.
Abstract: An improved antiperspirant composition is prepared by spray drying together a mixture of aluminum chloride, aluminum chlorhydrate, and urea. The impalpable powder which is formed is incorporated into an aerosol antiperspirant formulation.
Abstract: Quaternary ammonium salts having a lipophilic group covalently linked to the quaternary nitrogen through hydroxysuccinyloxy or hydroxysuccinylamino radicals are disclosed. These quaternary ammonium salts are useful as monomeric emulsion stabilizers.
Abstract: Heated lather is dispensed from a liquid body pressurized under gaseous propellant. Material is passed to a holding chamber which prevents reverse flow and wherein the separated portion is electrically heated. A second electrical device induces a current in the first electrical structure to elevate the temperature after which the material is discharged in an expanded state.
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.
