Abstract: An alkaline aqueous cleaning composition for cleaning a substrate, e.g., a plastic or metal substrate, contaminated with industrial-type soil contaminants contains (i) an aqueous portion and (ii) an active-ingredient portion composed of (A) an alkalinity-providing agent and (B) a surfactant mixture containing (a) an active concentration of an N-octyl-2-pyrrolidone surfactant and (b) an active concentration of at least one aminocarboxylic acid surfactant such as N-coco-beta-aminopropionic acid. The active-concentration ratio of surfactant (a) to surfactant (b) is such as to provide the cleaning composition with the ability to remove a substantial portion of the contaminants from the substrate. At an active-concentration ratio of surfactant (a) to surfactant (b) of about 2.5:1, the surfactants have a synergistic effect on the industrial-soil-removing ability of the aqueous composition.

Abstract: The present invention discloses an alkaline cleaning composition for cleaning heavily soiled metal surfaces such as food fryers, baking pans, high temperature pasteurizers, and beer kettles, ceramic surfaces such as restaurant grade ceramic china plates and platters, and plastic surfaces. The cleaning composition is noncaustic and includes a peroxygen compound, a chelate, and a metasilicate and/or sesquisilicate. A preferred cleaning composition further includes a surfactant and hydrated builder.

Abstract: A surface disinfectant and cleaning composition includes (a) a biocidal agent selected from the group consisting of glyoxal, glutaraldehyde, and mixtures thereof, (b) 0.001 to 1% by weight of a fluoroaliphatic tenside selected from the group consisting of perfluoroalkanoic acids wherein the alkane residue has 1 to 10 carbon atoms, alkali and ammonium salts thereof, and mixtures thereof, (c) 0.002 to 5% by weight of at least one ultraviolet absorber, (d) 0.001 to 3% by weight of an optical brightener selected from the group consisting of benzotriazole derivatives, stilbene disulfonic acid derivatives, and mixtures thereof, and (e) a solvent selected from the group consisting of water, water-soluble alcohols, and mixtures thereof, and having a pH value of 2.5 to 5.0.

Abstract: This invention relates to particular aqueous coating compositions comprising particular organic acids and processes of using these compositions to treat plastic moldings.

Abstract: Hydroxamic acids and hydroxamic acid ethers I and II ##STR1## where Z.sup.1 and Z.sup.2 are --NH --OY, --NR.sup.1 --OY or --OX, where in the case of (I) at least one of Z.sup.1 or Z.sup.2, and in the case of (II) Z.sup.1 is --NH --OY or --NR.sup.1 --OY, andR.sup.1 is C.sub.1 -C.sub.18 -alkyl,X is hydrogen, alkali metal, ammonium or substituted ammonium, andY is hydrogen, alkali metal, ammonium, substituted ammonium or C.sub.1 -C.sub.18 -alkyl, andL is a C.sub.1 -C.sub.100 linker which can also carry oxygen and nitrogen functional groups,with the exception of N,N-bis(carboxymethyl)-2-aminoacetohydroxamic acid.

Abstract: Limescale removing compositions contain a low level of surfactant, i.e., less than about 1% and maleic acid and have a pH of from about 0.1 to about 4.5. The surfactant can be anionic, nonionic, amphoteric, or cationic, but is preferably cationic. The composition can be used neat, or diluted, by applying it to the surface to be treated, leaving it to react, and then rinsing.

Abstract: The present invention discloses an alkaline cleaning composition for cleaning heavily soiled surfaces such as food fryers, baking pans, high temperature pasteurizers, beer kettles and similar equipment that normally requires caustic soda based cleaners to clean. The present invention is also useful in cleaning ceramics such as restaurant grade ceramic china plates and platters. The present invention is particularly useful in cleaning brass and aluminum parts and equipment without causing corrosion damage. Further, since the cleaning composition of the present invention is not based on caustic soda, the composition is not considered hazardous. Further, the cleaning composition of the present invention dissolves readily in water, providing a solution that can be used in mechanical sprayers, soak-tanks and clean-in-place equipment. Also the cleaning composition may be effectively used at lower temperatures than caustic cleaning agents.

Abstract: A solvent composition containing at least one of an alkyl .alpha.-alkoxyisobutyrate, an alkyl .beta.-alkoxyisobutyrate, and an alkyl .alpha.-hydroxyisobutyrate as an active component is disclosed. The solvent composition is of low toxicity and harmless to humans, has an extremely high dissolving power for high polymers, fats and oils, fluxes, liquid crystals, etc., produces no environment destructive substance, gives off no offensive odor, and has a relatively high boiling point indicative of safety and ease in handling.

Abstract: A biodegradable, acidic aqueous composition, with an anionic surfactant for the removal of rust, inorganic and organic deposits from a variety of surfaces. Said composition comprising Hydrochloric Acid, Phosphoric Acid, Tetrasodium EDTA, Anionic Surfactant, Perfume Oil, Dye and Water.

Abstract: Detergent compositions comprising nonionic detergent surfactant; unsaturated soap, i.e., oleate and/or ricinoleate; hydrophobic cleaning solvent; and aqueous solvent system. The compositions have excellent detergency properties and excellent filming/streaking properties. Preferred soaps are specific betaaminoalkanolammonium soaps, which provide superior filming/streaking properties as compared to, e.g., sodium soap.

Abstract: An improvement is described in microemulsion compositions which contain an anionic detergent, a nonionic surfactant, a grease release agent, a hydrocarbon ingredient, and water which comprises the use of a water-insoluble odoriferous perfume as the essential hydrocarbon ingredient in a proportion sufficient to form either a dilute o/w microemulsion composition containing, by weight, 1% to 20% of an anionic detergent, 6 to 50% of a cosurfactant, 1% to 10% of a grease release agent, 0.4% to 10% of perfume and the balance being water as well as a grease release solution, an all purpose hard surface cleaning composition or light duty liquid detergent compositions which contain a grease release agent.
