The present invention relates to a method of generating chlorine dioxide from chlorite salts in the presence of an iron ion-containing complex, a method of treating a substrate with a chlorine-containing oxidant in the presence of an iron ion-containing complex and related aqueous media, kits and compositions.

Solid, concentrated, multi-use, stabilized peroxygen bleach compositions are disclosed. The solid compositions employ a C6-C18 fatty acid binding system for improving shelf stability of an activated bleach composition containing a peroxygen source and a bleach activating agent. Methods of formulating and methods of use are further provided.

A method of washing dishware in a dishwasher comprising the step of delivering into the dishwasher: a) a first composition comprising oxygen bleach and substantially free of enzymes; followed by b) a second composition comprising enzymes wherein the first composition has a pH of at least 11 and the pH of the first composition is at least 1 pH unit greater the pH of the second composition wherein the pH is measured at wash concentration at 20 C.

Cleaning compositions may include at least 0.001 ppm of a polypeptide having hexosaminidase activity. The cleaning compositions may include a polypeptide having at least 60% sequence identity to the mature polypeptide shown in one or more of the motif(s) of SEQ ID NO 7, SEQ ID 8, SEQ ID 9, SEQ ID 10, SEQ ID 11, or combinations thereof. The cleaning compositions may be or include laundry detergents, fabric finishers, acidic cleaning agents, neutral cleaning agents, alkaline cleaning agents, hand dishwashing agents, automatic dishwasher compositions, or combinations thereof.

An HVAC fluid conditioning system may utilize chlorine (or other chemical) rods to treat an HVAC fluid. The chemical rod preferably has a length longer than a width (or diameter) of the rod to prevent the rod from tipping within a receptacle of the HVAC fluid conditioning system. The chemical rod may have a substantially circular cross-section wherein the width is equal to the diameter of the cross-section. The rod may have a length longer than about three inches and a width or diameter of about one inch or less. The circular rod may be formed by placing a rod with a substantially rectangular (e.g., square) cross-section into a press and pressing the rectangular rod between two molds, each having a semicircular opening, to form a rod having a substantially circular cross-section. A releasing agent may be applied to the rod or mold to facilitate easy release.

The present invention relates to a method of generating chlorine dioxide from chlorite salts in the presence of a manganese ion-containing complex, a method of treating a substrate with a chlorine-containing oxidant in the presence of a manganese ion-containing complex and related aqueous media, kits and compositions.

A water-soluble bleach additive for laundry detergents and surface cleaning detergents, of the type comprising a bleach agent, a bleach agent activator, and a builder. The bleach additive further comprises a sticky surfactant and, preferably, a water-soluble high molecular weight polymer and a plasticizer which allow to form the bleach additive in pellets through an extrusion process.

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.

Cleaning compositions may include polypeptides having hexosaminidase activity. The cleaning compositions may include a polypeptide having one or more of the motif(s) GXDE (SEQ ID NO 27), [EQ][NRSHA][YVFL][AGSTC][IVLF][EAQYN][SN] (SEQ ID NO: 28), HFHIGG (SEQ ID NO: 29), FLHLHF (SEQ ID NO: 30) or DHENYA (SEQ ID NO: 31), or combinations thereof. The cleaning compositions may be or include laundry detergents, fabric finishers, acidic cleaning agents, neutral cleaning agents, alkaline cleaning agents, hand dishwashing agents, automatic dishwasher compositions, or combinations thereof.

The present invention comprises chlorinated and non-chlorinated alkaline cleaning compositions for removal of proteinaceous and fatty soils at low temperature, i.e. less than 120 F., with little or no deleterious affect on cleaning performance. According to the invention, applicants have found that adding additional alkalinity makes protein removal more difficult and reducing the amount of alkalinity actually improves performance. According to the invention optimized combinations of chlorine and alkalinity components for low temperature cleaning as well as a surfactant system optimized for low temperature fatty soil removal are disclosed.
