The oxidizing agent may be hydrogen peroxide, sodium hypochlorite, chlorine dioxide, ozone, sodium hypobromite, sodium or potassium permanganate, or any combination thereof. The surfactant may include a C.sub.8-C.sub.10 alkyl polyglycoside and a C.sub.10-C.sub.18 alkyl polyglycoside.

A holder is formed of a single sheet, and includes two folding portions located at a predetermined distance in its longitudinal direction. The holder is folded in three by being divided by the two folding portions into a first holder-sheet portion, a second holder-sheet portion, and a third holder-sheet portion arranged in a stated order. A holding portion being a slit that holds a detergent packet, a rinse packet, and a support sheet is formed in the first holder-sheet portion.

wherein each R.sup.3 is independently selected from a hydrogen and a —C(O)CH.sub.3 group; and 10 to 65 wt % of structural units of formula III

##STR00003##

wherein each R.sup.4 is independently selected from a hydrogen and a —CH.sub.3 group; and wherein at least one of R.sup.1 and R.sup.2 is a C.sub.1-3 alkyl group in at least 1 mol % of the structural units of formula I in the dispersant polymer; wherein the dispersant polymer has a lactone end group and wherein the dispersant polymer has a weight average molecular weight of 1,500 to 6,000 Daltons.

An automatic dishwashing composition is provided including a builder selected from the group consisting of carbonate, bicarbonate, citrate, silicate and mixtures thereof; a nonionic surfactant; and a dispersant polymer comprising: (a) 5 to 75 wt % of structural units of itaconic acid; (b) 10 to 85 wt % of structural units having formula I

##STR00001##

wherein each R.sup.3 is independently selected from a hydrogen and a —C(O)CH.sub.3 group; and (c) 10 to 65 wt % of structural units of (meth)acrylic acid; wherein the dispersant polymer has a lactone end group and wherein the dispersant polymer has a weight average molecular weight of 1,500 to 6,000.

An automatic dishwashing detergent composition can include an alkoxylated polyalkyleneimine said alkoxylated polyalkyleneimine including a polyalkyleneimine backbone, alkoxy chains and quaternization groups wherein the alkoxylated polyalkyleneimine has a degree of quaternization of from about 40% to about 98% and wherein the polyalkyleneimine backbone represents from about 1% to about 40% by weight of the alkoxylated polyalkyleneimine and the alkoxy chains represent from about 60% to about 99% by weight of the alkoxylated polyalkyleneimine; percarbonate bleach; an amylase and a protease; and wherein the composition is free of bleach activator and bleach catalyst, or wherein the composition is free of bleach activator and includes manganese bleach catalyst.

The present disclosure pertains to surfactants for use in the formulation of detergents, foaming agents, emulsifiers, and degreasers. Some aspects of the invention include formulations suitable for cleaning and/or condition fabrics including upholstery. Some formulations are suitable for in home or commercial dry cleaning. Some of the formulations may be suitable for cleaning hard surfaces including plastic surfaces.

The present invention relates to a method of washing textile articles that can be carried out, for example, in a continuous batch tunnel washer. Embodiments of the present method can include treating the textile with an aqueous composition including cleaning agent and halogen-containing bleaching agent for a time sufficient to remove soil from the textile and contacting the halogen-treated textile with an aqueous composition including a peroxycarboxylic acid. The concentration of halogen after the sufficient time can be at a level that does not result in adverse interaction between the halogen-containing bleaching agent and the peroxycarboxylic acid. Embodiments of the present method can clean textiles with the results of more effective stain removal and less waste through destruction of the textile article. Further, the present invention can clean a textile contacted soiled by a composition including chlorhexidine gluconate without resulting staining of the textile, which staining could have been permanent.

The present invention relates to polypeptides having hexosaminidase activity, and polynucleotides encoding the polypeptides. The invention also relates to nucleic acid constructs, vectors, and host cells comprising the polynucleotides as well as methods of producing and using the polypeptides.

Formulations, methods using such a formulation, and systems encompassing such formulations and methods for reducing energy and/or water usage in an institutional laundry is provided. Such formulations, methods and systems allow for textiles and fabrics to be effectively washed even at temperatures as low as 20° C. A prewash formulation includes a surfactant enzyme booster with the surfactant enzyme booster having one but preferably more enzymes and one or more surfactants. The enzyme of the prewash formulation may include any one or more of a protease, a lipase, an amylase, a cellulase, a mannanase, a pectinase, a peroxidase, and a gluconase. A main wash formulation is used in a wash phase cycle of an institutional laundry where such a main wash formulation includes a bleach, bleach enhancer, a chelating agent, an anti-redeposition agent and/or a soil suspension agent, a surfactant, preferably a nonionic surfactant and an anionic surfactant, a solvent including an aqueous solvent and perhaps an organic solvent, and a builder. An institutional washing process using the formulations provided here are distinguished by the need to only include one rinse cycle—i.e., a rinse cycle between the prewash cycle and the main wash cycle is generally not needed or, at least, a full rinse cycle between the prewash cycle and the main wash cycle is not needed. The formulations, methods and systems provided reduce energy and water usage in an institutional laundry.
