Abstract: The composition of this invention is a stabilized acidic bleaching composition comprising an aqueous solution of a source of source of unipositive chlorine ion, a chlorine stabilizing agent, and an acidic buffer to stabilize the pH of the bleaching composition in the range from about 2 to 6.5, wherein the chlorine stabilizing agent and the source of source of unipositive chlorine ion are in a molar ratio of greater than about 1:1. Methods are described for removal of lime scale from a hard surface controlling microbial activity as well as reducing malodor by applying the composition of this invention.

Abstract: A cleaning composition for removing kinetically inert high oxidation state metal coordination complex stains, lime scale, soap scum, soil, grease, and biofilm deposits from ceramic surfaces, such as porcelain and glass, and other hard surfaces. The composition includes an acid component; a reducing component; a surfactant system component; and a complexing system component. In one aspect, the cleaning composition includes sulfamic acid, in an amount between about 20 and about 80 weight percent of the composition; isoascorbic acid, in an amount between about 0.1 and about 20 weight percent of the composition, for reducing kinetically inert high oxidation state metal coordination complex stains; a non-interfering surfactant system; and a complexing system comprising ethylenediaminetetraacetic acid and citric acid, the ethylenediaminetetraacetic acid comprising between about 0.

Abstract: A bleaching solution containing a peroxide and a saturated lactone bleaching enhancer in an alkaline medium is disclosed. Also disclosed is a bleaching system for forming the bleaching solution, as well as a method of preparing and using the bleaching solution. The bleaching solution may be employed as a cleaner for soiled hard surfaces, textiles and as a disinfectant.

Abstract: Disclosed herein are bleaching systems that contain a peroxide and an activator. The activator is a cyanopyridine N-oxide, preferably 2, 3, or 4-cyanopyridine N-oxide. The peroxide is preferably hydrogen peroxide. When such bleaching systems are utilized in an aqueous alkaline environment, they provide bleaching performance on a variety of stains on both hard and soft surfaces.

Abstract: A soft surface cleaning composition and method for effectively removing oxidizable and non-oxidizable stains without bleaching out the color of the soft surface. Comprising from about 0.2% to about 7.0% by weight of hydrogen peroxide, from about 0.5% to about 4.0% by weight of ethylene glycol n-hexyl ether, from about 0.2% to about 6.0% by weight of a surfactant and the balance water has a cloud point of at least 10.degree. C. remains a single phase at a temperature of about 20.degree. C. to about 40.degree. C. and dries to a non-tacky residue.

Abstract: Aqueous soft surface cleaning compositions comprising from about 0.1% to about 5.0% by wt. of a tertiary alkyl hydroperoxide; and from about 99.9% to about 95% by wt. of an aqueous alkaline cleaning composition comprising acetylenic alcohol and an anionic surfactant, which are stable, color-safe and produce satisfactory cleaning results, especially in removing red wine, grape juice, blueberry and blood stains from carpeting.

Abstract: Bleach activators are herein disclosed having the stoichiometric formula:[Cu(R.sub.1 R.sub.2 CHR.sub.5 (CH.sub.2).sub.n R.sub.6 CHNR.sub.3 R.sub.4)X.sub.m ] (I)wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5 and R.sub.6 are each a radical selected from the group consisting of hydrogen, alkyl, aryl, alkylaryl, arylalkyl, phenyl, benzyl and mixtures thereof,or R.sub.5 and R.sub.6 together form a hydrogen carbon ring,n is an integer from 0 to 1,m is an integer from 1 to 2, andX is selected from mono- and polyvalent anions.These bleach activators are combined with a peroxygen compound capable of releasing hydrogen perioxide in an aqueous solution. The combination is especially effective in the removal of hydrophobic stains from fabrics.
