摘要:
This invention relates to extend the benefits of using hypochlorite compounds such as sodium hypochlorite to clean and disinfect articles while reducing or eliminating the side effects of treating an article with a strong oxidant material. The invention relates to a single step process involving mixing of precursor compositions of a suitable hypohalite or hypohalous acid with a solution of a reducing agent. Optionally a buffer may be present in either or both precursor compositions, such that at time of use such active hypohalous acid concentration in the resulting aqueous mixture remains at a sufficient activity level to effect one or more desired benefits against a target substrate for a desired period of time. The oxidant is substantially consumed by reaction with the reducing agent after the time needed for achieving the desired benefit has passed.

Compositions and methods for improved cleaning using neutral cleaners are disclosed. In particular, neutral pH cleaning compositions according to the invention employ a synergistic combination of water insoluble surfactants and an anionic hydrotropes capable of forming a stable, low-foaming solution. The neutral cleaning solutions provide significant benefits over water insoluble microemulsions traditionally used for neutral cleaning compositions and provide at least equivalent cleaning efficacy as non-neutral cleaning compositions.
摘要:
A cleaning composition comprises at least one surfactant and at least one colorant. The cleaning composition can have a pH of about 3 or less. The colorant exhibits one of several specified structures at a pH of about 7. A method for cleaning a surface utilizes the cleaning composition.

Control systems for use of electrolysis solutions for automated recirculating or single-pass cleaning systems, such as clean-in-place (CIP) applications are disclosed. Control systems and methods for using automated chlorine output solutions for various cleaning applications are measurable over broad pH ranges. The control systems generate consistent and predictable electrolytic solutions and include a measurement system that identifies chlorine oxyanion concentration across broad ranges of pH, overcoming the sensitivity of chlorine monitors to pH and permitting use of the control systems to control cleaning systems.
摘要:
The present invention relates to acidic sanitizing and/or cleaning compositions comprising a specific quaternary antimicrobial system consisting of C1-C4 hydroxyalkyl carboxylic acids, C5-C18 alkyl monocarboxylic acids, unsubstituted or substituted, saturated or unsaturated C4-dicarboxylic acids and additional inorganic or organic acids. The compositions of the present invention can be present in the form of concentrates and in the form of diluted use solutions. They can be used in a process for sanitizing and/or cleaning hard surfaces, preferably in a cleaning-in-place (CIP) and/or sanitize-in-place (SIP) process for cleaning and/or sanitizing plants in the food, dairy, beverage, brewery and soft drink industries.
摘要:
A process is provided for producing target concentrations of peroxycarboxylic acids from carboxylic acid esters. More specifically, carboxylic acid esters are reacted with an inorganic peroxide, such as hydrogen peroxide, in the presence of an enzyme catalyst having perhydrolysis activity under conditions where control of reaction pH by selection of buffer concentration and concentration of perhydrolase and reactants produces a targeted concentration of peroxycarboxylic acids. The present perhydrolase catalysts are classified as members of the carbohydrate esterase family 7 (CE-7) based on the conserved structural features. Further, disinfectant formulations comprising the peracids produced by the processes described herein are provided, as are corresponding methods of use.
摘要:
A manual spray cleaner for removing dirt and stains from fabrics and carpets comprising a spray bottle having two separate chambers and a single dispensing spray outlet for dispensing controlled amounts of liquids from each of the chambers. One of the chambers has a fabric/carpet cleaning composition therein and the other chamber has an oxidizing composition that enhances the cleanability of the fabric/carpet cleaning composition. The fabric/carpet cleaning composition and the oxidizing composition are simultaneously drawn from their respective chambers and mixed together at the time that they are dispensed from the spray bottle. At least one of the oxidizing composition and the fabric/carpet cleaning composition includes a fabric/carpet protectant. The two compositions are mixed before or after they are sprayed from the bottle. The two compositions can be pressurized with an aerosol propellant or drawn from their respective chambers by a mechanical pump.
