Abstract:
1. A cleaning composition comprising: (i) 0.1 to 10 percent by weight of the cleaning composition of a biofilm-removing detergent solution comprising a combination of an alkyl (C8-18) polysaccharide, a non-ionic surfactant and a nitrogen containing surfactant-biocide; (ii) 2 to 80 percent by weight of the cleaning composition of one or more polar solvent selected from the group consisting of a primary or secondary alcohol, an ester, an ether, a ketone, a glycol, an aromatic alcohol, and a cyclic nitrogen solvent containing 8 or less carbon atoms; (iii) 0.5 to 15 percent by weight of the cleaning composition of one or more amines selected from the group consisting of urea, methyl and ethyl urea, aminomethane, alkylamines containing 1 to 4 carbon atoms, pyridine, paratoludine, and tetra (2-hydroxypropyl) ethylene diamine; (iv) two or more chelating agents selected from the group consisting of a substituted di and tri ethylamine, derivatives of phosphonic acid and its substituted derivatives, derivatives of nitrilotriacetic acid, derivatives of gluconic acid, glycine and derivatives thereof; (v) 0.1 to 5.0 percent by weight of the cleaning composition of an alkaline buffer system providing a pH of about 11.5 to 13.3 in aqueous solution, comprising low molecular weight organic and/or hydroxyl organic acids containing 7 or less carbon atoms, and a mono valent alkali metal hydroxide; and (vi) 0.005 to 5.0 percent by weight of the cleaning composition of an organofunctional silane.
