International Classification:

C11D 936
C11D 710
C11D 3386

US Classification:

510317

Abstract:

A granular detergent composition is provided. The detergent composition comprises at least about 1% by weight of a surfactant and at least about 1% by weight of a builder. The detergent composition also includes from about 6 to about 9% of a particulate foam control agent. In addition, the detergent composition includes from about 0. 1 to about 10% of hydrated magnesium sulfate, from about 0. 05 to about 0. 4% of a protease enzyme, and from about 0. 05 to about 0. 2% of a cellulase enzyme. The detergent composition produces the low level of foam required for optimal cleaning in washing machines employing a low water wash process.

International Classification:

C11D 172

US Classification:

510321

Abstract:

An emulsified detergent composition is provided. The detergent composition comprises from about 0. 1% to about 70%, by weight of the detergent composition, of a detersive surfactant wherein at least from about 70% to about 90%, by weight of the detersive surfactant, is a nonionic surfactant. The detergent composition also includes an electrolyte, in an amount sufficient to render the cloud point of the detergent composition to be less than about 20. degree. C. , and water. The detersive surfactant and the water are in two phases in a weight ratio of about 1:10 to about 10:1 in the detergent composition. Superior cleaning and stain removal results because the emulsified detergent composition provides separation of the water and surfactant phases in a low water wash system over a broad temperature range and allows for cleaning below the cloud point of the surfactant system.

US Classification:

8137

Abstract:

A method of laundering soiled fabrics comprises contacting the fabrics in an aqueous laundering solution with a granular detergent composition comprising at least about 1% by weight of a surfactant, at least about 1% by weight of a builder, from about 6% to about 9% by weight of a particulate foam control agent, from about 1% to about 5% by weight of bleach activator, from about 0. 3% to about 7% by weight of a peroxygen bleaching agent and from about 0. 05% to about 0. 2% by weight of a cellulase enzyme, wherein the detergent composition produces the low level of foam required for optimal cleaning in washing machines employing a low water wash process.

International Classification:

C11D 1706
C11D 112
C11D 137

US Classification:

252549

Abstract:

A process for making a detergent composition in form of agglomerates is provided. The process for making a detergent composition comprises the step of adding a paste mixture to a mixer/densifier, wherein the paste mixture includes from about 1% to 50% by weight of a detersive surfactant system comprising at least about 30% of a sulfated suffactant selected from the group consisting of alkyl sulfates, alkyl ethoxy sulfates, secondary alkyl sulfates and mixtures thereof, and from about 1% to 50% of a hydrotrope selected from the group consisting of sulfyl succinates, xylene sulfonates, cumene sulfonates and mixtures thereof. The process also includes the steps of mixing at least about 1% by weight of a detergency builder into the mixer/densifier, and agglomerating the paste mixture and the builder into detergent agglomerates which are substantially free of phosphates. The anionic surfactants in the detergent composition have significantly improved dissolution in aqueous laundering solutions, especially those kept at cold temperatures, i. e. 5. degree. C. to 30. degree. C.

Abstract:

A detergent composition in form of agglomerates is provided. The detergent composition contains from about 1% to about 50% by weight of a detersive surfactant system. The surfactant system itself includes, by weight of the surfactant system, at least about 30% of a sulfated surfactant selected from alkyl sulfates, alkyl ethoxy sulfates, secondary alkyl sulfates and mixtures thereof. The detergent includes from about 1% to about 50% of a hydrotrope selected from the group consisting of sulfyl succinates, xylene sulfonates, cumene sulfonates and mixtures thereof. Also, the detergent composition includes at least about 1% by weight of a detergency builder to enhance cleaning. The surfactant system, hydrotrope and builder are agglomerated to form detergent agglomerates which are substantially free of phosphates. The anionic surfactants in the detergent composition have significantly improved dissolution in aqueous laundering solutions, especially those kept at cold temperatures, i. e. 5. degree. C. to 30. degree. C.

US Classification:

510349

Abstract:

A detergent composition containing an inexpensive detergent builder in the form of a selected crystalline calcium carbonate that has been coated with a hydrotrope is provided. The crystalline calcium carbonate can be calcite and the hydrotrope can be xylene sulfonate. The crystalline calcium carbonate of the present invention is extremely inexpensive because it performs well even when used at large median particle sizes (e. g. less than 10 m. sup. 2 /g surface areas).
