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.

Disclosed are microwave assisted methods and systems for decontaminating a variety of contaminated surfaces. The systems and methods comprise treating the surfaces with benign chemical formulations followed by exposing to microwave irradiation for short periods of time to achieve at least 6-log reduction in biological contaminants including spores of B. anthracis, B. thuringiensis, and P. roqueforti. Chemical formulations may comprise copper (II) chloride in water. The formulations may include a surfactant such as a polyethylene sorbitol ester surfactant.

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

The oxidizing and bleaching effect of peroxygen compounds at low temperatures was to be improved. This was substantially achieved through the use of organic peroxoacids under perhydrolysis conditions with compounds which form cationic groups and in which a quaternary nitrogen atom is part of a heterocyclic 5-membered functional group.

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.

An encapsulation composition is described. The composition comprises a plurality of capsules, each capsule comprising an amphiphilic material encapsulating a pyrethroid. The encapsulated pyrethroid has a release rate less than the release rate of the unencapsulated pyrethroid. Coated fabric products are also described.

A method of laundering fabric, where the method includes the steps of: (a) in a main washing step, washing soiled fabric with an aqueous wash bath including detersive surfactant and photo-bleach; and (b) in a rinsing step, rinsing the soiled fabric with an aqueous rinsing solution including perfume, where an artificial light source is present and turned on during at least part of the main washing step (a) and provides light to the wash liquor in such a manner that activates the photo-bleach present in the wash liquor, and where the artificial light source is turned off during at least part of the rinsing step (b) and does not provide any light to the aqueous rinsing solution.

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.

Methods, systems, and apparatuses for producing one or more of trioxygen, reactive nitrogen species, hydrogen, oxygen, and electronically modified oxygen derivatives from oxidizing agents that are exposed to certain frequencies of radiation, exposed for certain amounts of time, and exposed to certain intensities of radiation. The oxidizing agent or oxidizing agents can be exposed to multiple frequencies of radiation and multiple exposures of radiation. A combination of one or more oxidizing agents and radiation of certain wavelengths forms a synergistic reaction. The synergistic reaction generates, among other agents, RNS, EMODs, which can further produce variation in the standard chemical reaction associated with the decomposition of the oxidizing agent. This reaction variation may produce RNS, trioxygen, hydrogen and/or its isotopes, and/or oxygen and/or its isotopes and/or electronically modifies oxygen derivatives. This synergistic reaction has a relationship to EMOD creation, Oxygen and its isotope generation and hydrogen and its isotope generation.

A composition in the form of a tablet for neutralizing toilet odor and preventing bacterial growth comprising proteolytic enzymes (protease) and a complex of sodium bicarbonate, citric acid, and a surfactant for foaming, as well as EDTA disodium (Trilon B), sodium percarbonate, dye, and fragrance.
