A method of laundering articles, the method comprising combining a detergent composition and water to provide a detergent solution, wherein the detergent composition comprises a surfactant system containing a betaine, then introducing into a washing machine basket the detergent solution so as to dampen articles in the basket; and then waiting for a duration of time during which no water or further detergent solution is added to the basket containing the dampened articles.

A concentrate aqueous composition for removing Type I and Type III rouge from various stainless-steel items. The liquid composition comprises oxalic acid, a phosphonic acid, and various amines. The use of an amine has been found to provide synergistic results in removal of the noted types of corrosion from various stainless-steel items that include medical instruments, machines, equipment, pipes, tools, mixing and storage vessels, and the like.

An aqueous cleaning composition for removing paraffin, asphaltene, and scale deposits or plugs from a hydrocarbon system. The aqueous cleaning composition is formed of a cleaning composition and an aqueous liquid. The cleaning composition contains about 21-33% of a silicate, about 20-35% of a peroxygen, about 3-15% of a phosphate, about 15-40% of a carbonate or bicarbonate, about 1-10% of a chelating agent, about 1-5.5% of a surfactant combination. In one embodiment, the surfactant combination includes a surfactant polymer mixture containing a block polymer and a reverse polymer, and a wetting agent containing a sulfonated material or an ethoxylated alcohol.

A method of making a non-fibrous laundry detergent sheet can include dispensing a microcapsule onto a precursor non-fibrous laundry detergent sheet, wherein the precursor non-fibrous laundry detergent sheet can include: (a) at least one surfactant; (b) at least one film former; and (c) a thickness ranging from 0.1 mm to 10 mm.

A water-soluble bleach additive for laundry detergents and surface cleaning detergents, of the type comprising a bleach agent, a bleach agent activator, and a builder. The bleach additive further comprises a sticky surfactant and, preferably, a water-soluble high molecular weight polymer and a plasticizer which allow to form the bleach additive in pellets through an extrusion process.

Disclosed are inhibitor/cleaner compositions comprising alkyldiphenyloxide disulfonates, and methods of inhibiting corrosion of and removing schmoo from metal containments in contact with corrosive water sources. Also disclosed are metal containment assemblages comprising inhibitor/cleaner compositions and metal containment therefore. The alkyldiphenyloxide disulfonates are soluble or substantially soluble in the water sources and inhibit corrosion of the metal containments by the water sources containing corrodents. The alkyldiphenyloxide disulfonates also remove schmoo from the metal containments. The inhibitor/cleaners of the invention are useful for addition to produced waters and other corrosive water sources resulting from enhanced oil recovery operations. The inhibitor/cleaners inhibit corrosion of tanks, devices, and other metal containments such as carbon steel pipes which come into contact with produced waters from the oil recovery operations, while also providing schmoo reduction and removal from the metal containments. The inhibitor cleaners are also useful for addition to other corrosive aqueous fluids to inhibit corrosion of metal containments with which the aqueous fluids come into contact, such as corrosive aqueous discharge from mines and other industrial operations such as paper-making.
