Abstract: Concentrated cleaning compositions are described which exhibit an increase in viscosity simply upon dilution with water. The concentrated and diluted ("ready-to-use") versions are useful in removing food and petroleum grease from hard surfaces (particularly non-horizontal surfaces), and may be formulated as petroleum degreasers, hand soaps and bathroom cleaners. The inventive compositions include an aggregate-forming organic compound, for example an amine oxide, and a nonaggregating or mildly aggregating organic compound, such as an organic alkyl alcohol having from about 4 to about 20 carbon atoms.

Abstract: The present invention is drawn toward compositions and methods of using same, the compositions comprising (in diluted form):a) an effective amount of a phenyl substituted alkyl alcohol having a water solubility of at least 0.1 weight percent (preferably benzyl alcohol);b) a coupler; andc) water,wherein the amount of the coupler is at least 3.0 times the amount necessary to completely solubilize the phenyl substituted alkyl alcohol in the water. Preferred couplers are the salt of a monofunctional water-soluble amine and an organic acid comprising at least one water-insoluble organic acid having from 6-10 carbon atoms. Methods of removing coatings such as standard urethane/acrylic sealer finishes from floors using the inventive compositions are also described.

Abstract: Multi-surface cleaning compositions and methods of use are presented. Compositions within the invention which are substantially non-streaking on hard surfaces comprise:a) a surfactant selected from the group consisting of amine oxides within the general formula (I) ##STR1## and quaternary amine salts within the general formula (II) ##STR2## b) a very slightly water-soluble polar organic compound; and c) an effective amount of a water soluble organic compound selected from water soluble glycol ethers and water soluble alkyl alcohols.wherein R.sup.1 and R.sup.2 are the same or different and are selected from the group consisting of alkyl and substituted alkyl groups, R.sup.3 is selected from the group consisting of straight chain alkyls, branched chain alkyls, straight chain heteroalkyls, and branched chain heteroalkyls having from about 10 to 20 carbon atoms, R.sup.

Abstract: A nonwoven surface treating article suitable for treating surfaces which include calcium carbonate, such as marble floors, includes an open, lofty, three-dimensional nonwoven web of a plurality of thermoplastic organic fibers, a binder, and abrasive particles having an average particle diameter ranging from about 0.1 micrometer to about 30 micrometers. The abrasive articles of the invention do not rust, as do steel wool pads, and produce a high gloss, durable surface. A system for treating calcium carbonate-containing surfaces is also presented, the system including the articles and an acidic crystallization agent. Methods of treating calcium carbonate-containing surfaces with the system are also presented.

Abstract: A composition having a high chelation value may be made by blending about 50 to 80 wt-% of a polyether such as polyethylene glycol, about 20 to 50 wt-% of a polycarboxylate such as polyacrylate moiety or an acrylate monomer, and about 0.1 to 0.5 mole-%, based upon the polyacrylate moiety or the monomer, of an organic peroxy catalyst such as t-butyl perbenzoate at a temperature below about 110.degree. C. but sufficient to liquefy the blend and cause grafting of a polyether on the polycarboxylate.

Abstract: A uniform, continuous sanitizing film can be formed by simultaneously spraying a two-package aqueous sanitizing composition comprising in a first solution a quaternary ammonium salt compound and in a second solution a polymer containing acid functionality. The sprays are directed to areas of substantial overlap resulting in a reaction between the quaternary ammonium compound and the carboxylic acid functional polymeric compound resulting in formation of a water insoluble film.
