Embodiment 1

[0038] Table 1 shows the storage stability of several exemplary stabilized concentrated cleaning solutions prepared according to the present invention, as well as several comparative solutions. Each solution was prepared by simply combining the components in the order and amounts indicated. Furthermore, all amounts indicated are percent by weight, based on the total weight of the solution.

[0039] Once prepared, the solutions were stored at or around room temperature (25°C) and visual evaluations were taken at 10 weeks, 3 months, 6 months and 1 year. The results of the evaluation were graded as follows: 0 = no deposits, 1 = minimal deposits, commercially acceptable, 2 = little deposits, commercially unacceptable, 3 = many deposits, commercially unacceptable.

Abstract

The invention is directed to stabilized concentrated cleaning solutions comprising a source of hypochlorite ions and to a method for providing the stabilized concentrated cleaning solutions. The stabilized concentrated cleaning solutions according to the invention comprise a hydroxide ion source, hypochlorite ion source, and a chelating agent, and are provided simply by mixing the various components together. The stabilized concentrated cleaning solutions exhibit stability against, e.g., dilution with a diluent comprising amounts of copper, iron, nickel cobalt, etc., as well as storage for periods of from about 10 weeks to up to about 1 year without undergoing visible deterioration and / or a substantial deterioration in efficacy.

Description

technical field [0001] The present invention relates to stabilized concentrated cleaning solutions and methods for their preparation. Background technique [0002] Commercial cleaning fluids that effectively clean, sanitize, and disinfect are of critical importance in many industrial and institutional settings and are even ubiquitous in healthcare, food manufacturing, education, government, agriculture, water treatment, and more. Due at least in part to cost considerations, these cleaning solutions are typically manufactured and sold in concentrated form and then diluted to their usable concentration at the point of use. [0003] Many users of these solutions maintain stock in stock and, as a result, the concentrated cleaning solutions may sit for extended periods before use. However, the storage stability of concentrated solutions has proven limited in some applications. Although clear when prepared, concentrated solutions may tend to partially decompose, or deteriorate, ...
