Abstract:
1. An aqueous hard surface cleaning and disinfecting composition comprising: (a) a first acid sequestrant constituent comprising citric acid and at least one second acid sequestrant selected from the group consisting of cresylic acid, dodecylbenzene sulfonic acid, phosphoric acid, salicylic acid, sorbic acid, sulfamic acid, acetic acid, benzoic acid, boric acid, capric acid, caproic acid, cyanuric acid, dihydroacetic acid, dimethylsulfamic acid, propionic acid, polyacrylic acid, 2-ethyl hexanoic acid, formic acid, fumaric acid, 1-glutamic acid, isopropyl sulfamic acid, naphthenic acid, oxalic acid, phosphorus acid, valeric acid, benzene sulfonic acid, xylene sulfonic acid, sulfonic acids, maleic acid, acetic acid, adipic acid, lactic acid, butyric acid, gluconic acid, malic acid, tartaric acid, and glycolic acid; (b) a mixture of hydrophobic and hydrophilic solvents wherein said hydrophobic solvent exhibits a solubility in water of about 0 to about 20 ml per 100 ml of water, and which comprises about 51 to about 99 wt. % of said mixture of solvents, and wherein said hydrophilic solvent comprises about 1 to about 49 wt % of said mixture of solvents; (c) about 0.001 to less than about 1% by weight of a single constituent which exhibits both anionic surfactant and hydrotrope properties and is at least one selected from the group, consisting of alkyl phenoxy benzene disulfonates, linear alkyl benzene sulfonates, alkyl naphthalene sulfonates and salts thereof; (d) about 0 to about 20% by weight of one or more optional constituents; and (e) the balance to 100% by weight water, wherein the aqueous hard surface cleaning and disinfecting composition exhibits a pH of 7 or less.
