The present invention relates to a process for washing fabrics in the drum of an automatic washing machine.

A method for waste material treatment that results in a more stable, entombed treated waste product. A reactive treatment formulation can be dispensed with a waste material deposit into a self-contained non-contact agitating toilet to form a stabilized viscous mass. The reactive treatment formulation mixed with the waste material deposit prevents odors, bacterial growth, and stabilizes the waste material into a treated waste product to reduce spillage during disposal.

Methods of washing laundry in an automatic laundry machine using a multicompartment water-soluble unit dose article having a water-soluble film and a liquid laundry detergent composition, wherein the unit dose article has a height, a width and a length, wherein the length is the longest dimension and the height is the smallest dimension, and wherein the ratio of the maximum length to the maximum height is between about 2:1 and about 10:1, wherein the unit does article comprises a gas, and wherein the ratio of the volume of said gas to the volume of the liquid laundry detergent composition is between about 1:25 and about 1:10.

Methods of washing laundry in an automatic laundry washing machine using multicompartment water-soluble unit dose articles having a water-soluble film and a liquid laundry detergent composition, wherein at least one compartment of the unit dose article has the liquid laundry detergent composition and wherein the unit dose has a height, a width and a length, wherein; the maximum length is between about 2 and about 5 cm; the maximum width is between about 2 and about 5 cm; and the maximum height is between about 3 and about 5 cm; and wherein the volume of the liquid laundry detergent composition within the water-soluble unit dose is between about 10 and about 20 ml.

A detergent composition including an acyl hydrazone bleach catalyst and a protease having at least a 70% sequence identity to SEQ ID NO:1.

Water-soluble unit dose articles including a bleach catalyst and methods of their use.

A water-soluble unit dose article that includes a water-soluble film and powder composition, where the powder composition includes a) an acyl hydrazone bleach catalyst; b) from 1% to 10% by weight of the composition of an alkali metal carbonate; c) from 5% to 20% by weight of the composition of an alkali metal bicarbonate; d) from 5% to 20% by weight of the composition of an alkali metal silicate; e) from 5% to 20% by weight of the composition of an alkali metal sulphate.

A water-soluble unit dose article including a water-soluble film and a first compartment and a second compartment, where the first compartment includes a powder composition, where the powder composition includes an acyl hydrazone bleach catalyst; and where the second compartment includes a liquid composition, where the liquid composition includes between about 10% and about 25% by weight of the liquid composition of a non-aqueous solvent system; where the non-aqueous solvent system includes a polyol and a monoalcohol.

The invention provides a powdered composition of additives and a method of use thereof for increasing the visibility, potency and coverage of disinfectant solutions, such as bleach.

A detergent or cleaning agent, in particular a cleaning agent for hard surfaces, having at least two phases which are different from one another.
