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: Disclosed herein are hard surface cleaners and methods for creating and using them. The cleaners combine a monocarboxylic acid with an ampholytic surfactant having no carboxyl groups, in an aqueous solution. In one aspect, lactic acid, water, and sodium caprylo ampho hydroxpropyl sulphonate are present.

Abstract: The invention relates to a composition for an aqueous rinsing solution for removing deposits from surfaces of showers and the like, and the use of such a composition for rinsing showers clean and for providing a pleasant sheen to shower surfaces without scrubbing or wiping. The composition includes a cleaning surfactant, an alcohol, and optionally, a super wetting surfactant, a disinfectant and a base for adjusting pH.

Abstract: An aqueous hard surface cleaner with improved soil removal is provided and has, as components, the following:(a) either a nonionic or amphoteric surfactant with optionally, a quaternary ammonium surfactant, the total amount of the surfactants being present in a cleaning effective amount;(b) at least one water-soluble or dispersible organic solvent having a vapor pressure of at least 0.001 mm Hg at 25.degree. C., present in a solubilizing--or dispersion--effective amount;(c) Ammonium ethylenediamine-tetraacetate (ammonium EDTA) as a chelating agent, present in an amount effective to enhance soil removal in said cleaner; and(d) the remainder, water.

Abstract: A floor stripper composition is provided, having a pH-value above 9.0, and comprising a soap, water and a glycine-N,N-diacetic acid compound, which is preferably methylglycine diacetic acid (MGDA). The diacetic acid is desirably in the form of a divalent metal complex thereof. A process is also provided for removing a zinc containing acrylate polymer film from a floor surface, wherein a floor stripper composition of the invention is applied. A good floor stripper performance could be obtained with this composition owing to its low foaming behaviour.

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: Effective, multi-use filter cleaning compositions include 5% to 60% of a strong acid, 1% to 40% of a surfactant, and 0.5% to 20% of a sequesterant/builder. The filter cleaning compositions optionally include 0.5% to 10% of a water soluble organic solvent, and/or 0.5% to 10% of a nonionic surfactant.

Abstract: A detergent composition for hard surfaces includes (a) 0.1-30 wt. % of a cationic surfactant represented by the general formula (1) or (2): ##STR1## wherein R.sup.1 is a linear or branched alkyl or alkenyl group having 6-11 carbon atoms, R.sup.2 is a methyl group or a linear or branched alkyl or alkenyl group having 6-11 carbon atoms, R.sup.3 is a linear or branched alkyl or alkenyl group having 6-11 carbon atoms, and X is a halogen atom or a residue of an alkylsulfuric acid; (b) 0.1-20 wt. % of a sequestering agent; and (c) 0.1-20 wt. % of a water-soluble solvent. The composition has a pH of 3-12. Since the detergent composition is excellent in the ability to decompose and solubilize metallic soap scum, the dirt on a bathtub and the like in a bathroom can be quickly and easily cleansed off.

Abstract: Cleaning compositions are presented which surprising exhibit increased cleaning performance as the amount of solubilizing coupler is increased beyond that necessary to fully solubilize a very slightly water-soluble organic solvent component. Methods of use of the compositions to remove hydrophobic soils and soap scum are also described.

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: Acidic aqueous cleaning compositions containing a strong acid and maleic acid are disclosed. The maleic acid provides improved surface safety.

Abstract: An acidic thickened composition which is sprayable and readily clings to vertical walls and is effective in removing heavy encrusted lime scale and soap scum.

Abstract: This invention relates to a liquid crystal composition comprising a water insoluble organic compound, a sulfonate surfactant, an abrasive, an ethoxylated alkyl ether sulfate surfactant, a cosurfactant and water.

Abstract: Acidic cleaning compositions which are self-thickened by a thickening system comprising a mixture of a quaternary ammonium compound cationic surfactant and a nonionic surfactant. The compositions are for hard surface cleaning and are specifically suitable for the removal of limescale.

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: The scale formed by use of alkaline salt-based cleaners and which comprises one or more alkaline salts and organic scale is removed by applying an aqueous solution comprising alkali metal carbonate salts and optionally, a hydrotrope to remove the organic scale. A mixture of potassium and sodium carbonate salts has been found to effect better descaling than use of either of the salts alone.
