A water soluble strip that includes a carrier film that include water soluble polymer, one or more actives and one or more agents such as heat forming agent and/or degrading accelerator. The water soluble strip can optionally include other additives. The actives includes antimicrobial agent, cleaning agent and/or surfactant. The water soluble strip can include other materials. The heat forming agent and/or degrading accelerator, when used, are designed facilitate in degrading or dissolving the water soluble strip and/or increase the activity of the one or more actives. The water soluble film can be used for a variety of applications such as a hard surface cleaning strip, dishwashing strip, laundry cleaning strip, stop removing strip, drain unclogging strip, toilet bowl cleaning strip and the like.

Detergent tablets are dispersed by means of gas entrapped within the detergent ingredients. Tablets for use in dishwashers provide an in-use alkaline wash liquor by dissolving quickly.

A composition is provided comprising two liquids which are separately maintained prior to forming an admixture during delivery to a surface to be treated, whereupon the admixture generates a foam sufficient for cleaning efficacy and stability. A first liquid preferably includes a hypohalite, or a hypohalite generating agent and a second liquid preferably includes a peroxygen agent. As the two liquids are initially separated, the hypohalite generating agent can be maintained in an environment free of peroxygen agent and otherwise conducive to their cleaning activity and stability up to the time of use. When the two liquids are allowed to mix, for example, by simultaneously pouring into a drain, the hypohalite and peroxygen react to liberate oxygen gas. As foam generation occurs, the escaping gas contacts surfactant in the solution, and creates foam which expands to completely fill the drain pipe. The expanded foam contains an excess of the hypohalite, which acts to clean the drain. A method of cleaning drains is provided which comprises the step of pouring into a drain at least one liquid which generates foam in situ, the foam characterized by a density of at least about 0.1 g/ml, a half life of greater than about thirty minutes, a volume of at least about 500 ml, and wherein the foam contains a cleaning-effective amount of a drain cleaning active.

Hand dish compositions such as those that are typically provided to the consumer in liquid form are disclosed. The hand dish composition is in the form of a flexible, porous, dissolvable substrate. The substrate may comprise hand care compositions. The article may take any number of suitable shapes.

Date Feb. 5, 1998Disclosed are detergent compositions with improved solubility having a bulk density of at least 600 g/l, comprising a branched surfactant and from about 1% to about 3% a particulate acid source which is citric acid and an alkaline source, wherein said acid source and alkaline source are capable of reacting together to produce a gas, and wherein about 80% or more of the acid source has a particle size in the range of from about 150 microns to about 710 microns, with at least 37% by weight of the acid source having a particle size of about 350 microns or less.

The present invention relates to a method of cleaning the interior surfaces of a non-loaded washing machine or a non-loaded automatic dishwasher with a particulate composition by forming in said washing machine or automatic dishwasher an acidic aqueous liquor comprising water and dissolved or dispersed therein said particulate composition, wherein said particulate composition comprises an effervescence system and sufficient acid to form an acidic aqueous liquor having a pH of below about 4.

An aerosol product comprises a foaming concentrate composition that comprises a surfactant and particulate material having a particle size of at least about 100 μm. The foaming concentrate composition and propellant are contained in a package comprising a container and a powder valve comprising an orifice having an orifice diameter of at least about 660 μm. Preferably, a ratio of the maximum particle size of the particulate material to the orifice diameter of the orifice is less than about 0.75.

This invention relates to a detergent composition comprising an anionic surfactant and a cationic surfactant, an acid source and an alkali source capable of reacting together in the presence of water to produce a gas.

This invention relates to an enzymatic detergent drain cleaner composition containing: 0.015-20 wt % of an acid cellulase enzyme having hydrolytic activity specific to beta -glucosidic bonds; 1-70 wt % of a water soluble carbonate salt; 1-70 wt % of a water soluble acid that reacts in an aqueous medium with the carbonate salt to form carbon dioxide that dissolves in the aqueous medium; 0.1-10 wt % of a surfactant; and 0.05-5 wt % of a thickening agent. This detergent composition may be used as an enzymatic detergent drain cleaner or in a method for removing or preventing bacterial cellulose deposits in an aqueous system at a solution temperature of up to about 60 DEG C. and a pH of about 2 to about 7.

A composition is provided comprising three liquids which are separately maintained prior to forming an admixture during delivery to a surface to be treated, whereupon the admixture generates a heated foam sufficient for cleaning efficacy and stability. A first liquid preferably includes a hypohalite, or a hypohalite generating agent, a second liquid preferably includes a peroxygen agent and a third liquid includes a reducing agent, such as a thiosulfate. The first liquid is thickened to a specified rheology, resulting in the generation of a highly effective foam. As the liquids are initially separated, they can be maintained in an environment free of reactants and otherwise conducive to their activity and stability up to the time of use. When the liquids are allowed to mix, for example, by simultaneously pouring into a drain, the hypohalite and peroxygen react to liberate oxygen gas, while the hypohalite and thiosulfate react to generate heat. As foam generation occurs, the escaping gas contacts surfactant in the solution, and creates foam which expands to completely fill the drain pipe. The expanded foam is hot as a consequence of athe exothermic reaction, and further contains an excess of the hypohalite, both of which act to clean the drain.
