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.

A method of treating a drainage system includes puncturing, by a controller, a pod retained by a pod housing, wherein the pod contains a drain treatment compound, and introducing, by the controller, water from a water supply to the pod retained by the pod housing to deliver the drain treatment compound dispersed in the water to a drain.

The present invention relates to compounds which form, under perhydrolysis conditions, certain cationic organic peracids, to the use of said compounds for activating peroxygen compounds in the context of bleaching stains when washing textiles and cleaning hard surfaces, and to washing and cleaning agents that contain said compounds.

It is an object to provide a novel wet wiper in which a sterilization effect and a wiping/cleaning effect are maintained even when the wet wiper is stored for a long period of time. A wet wiper is provided which includes: a fabric; and a chlorine-based treatment agent included in the fabric, wherein the chlorine-based treatment agent includes at least one of chlorous acid (HClO.sub.2), chlorite ion (ClO.sub.2.sup.−), and chlorine dioxide (ClO.sub.2) as an effective chlorine component.

A washing agent portion unit includes a solid washing agent or cleaning agent, and a water-soluble wrapping that completely encloses the solid washing agent or cleaning agent, wherein the water-soluble wrapping consists at least in part of a water-soluble nonwoven. The present invention further relates to a method for producing said washing agent portion unit, and to a washing method using said washing agent portion unit.

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 invention relates to a method of automatic dishwashing, comprising: placing soiled wares inside a cleaning volume; providing a first cleaning composition comprising a bleach and a second cleaning composition different from the first composition; and delivering the first composition and the second composition separately to the cleaning volume to contact the soiled wares, wherein: the first composition is delivered to the cleaning volume as a mist and the second composition is delivered to the cleaning volume as a jet; and the first and second compositions are delivered to the cleaning volume at a temperature below 100° C. The invention also relates to a dishwasher and a kit for use in the inventive method.

Process for making a powder or granule containing (A) at least one chelating agent selected from alkali metal salts of methyl glycine diacetic acid (MGDA) and of iminodisuccinic acid (IDS), (B) at least one compound of general formula (I a) or (I b)

##STR00001## wherein A.sup.1 is selected from (CH.sub.2).sub.a wherein the variable a is in the range of from 4 to 20, e is selected from zero and 1, and R.sup.1 being the same or different and selected from O—C.sub.1-C.sub.10-alkyl and C.sub.1-C.sub.10-alkyl, and, optionally, (C) at least one homo- or copolymer of (meth)acrylic acid, partially or fully neutralized with alkali, said process comprising the steps of (a) providing an aqueous solution or slurry containing chelating agent (A) and said compound (B) and, if applicable, (co)polymer (C), with a pH value in the range of from 10 to 12, (b) removing most of said water by spray drying or spray granulation.

The present invention relates to a composition, preferably a laundry detergent composition or a laundry additive composition, comprising at least one bleaching agent, at least one bleach activator, at least one oxygen transfer agent, and at least one protease, wherein: the composition comprises between 20 wt. % and 50 wt. % of said at least one bleaching agent, based on the total weight of the composition; and the composition comprises between 0.001 wt. % and 2 wt. % of said at least one oxygen transfer agent, based on the total weight of the composition, wherein said at last one oxygen transfer agent is selected from the group comprising 3-methyl-1,2-benzisothiazol-1,1-dioxide, 1,2,3-Benzoxathiazine, 2,2-dioxide, and combinations thereof. The invention further relates to a method of a laundering a fabric in a laundry washing machine. It also relates to the use of the composition for the removal of stains, malodour removal, and preferably whiteness improvement.

The disclosure provides compositions and methods for making a colorized solution of an aqueous disinfectant that is both stable in bulk solution and will fade to clear within a predetermined period of time after being applied to a surface, for example as a spray or film. The compositions and methods described here allow an end user to visualize both the extent of coverage and the duration of contact of the disinfectant with the surface, thereby providing more efficient disinfection of the surface.
