Abstract

The invention provides an aqueous, antimicrobial, no-rinse hard surface cleaner with significantly improved residue removal and substantially reduced filming/streaking, said cleaner comprising:

(a) an effective amount of a solvent selected from C_1-6 alkanol, C_3-24 alkylene glycol ether, and mixtures thereof;

(b) an effective amount of a surfactant selected from amphoteric, nonionic surfactants, and mixtures thereof;

(c) an effective amount of a quaternary ammonium surfactant;

(d) an effective amount of a builder; and

(e) the remainder as substantially all water.

Claims

1. An aqueous, antimicrobial hard surface cleaner with significantly improved residue removal and substantially reduced filming/streaking, said cleaner comprising:

(a) an effective amount of a solvent selected from C_1-6 alkanol, C_3-24 alkylene glycol ether, and mixtures thereof;

(b) an effective amount of amine oxide surfactant;

(c) an effective amount of a quaternary ammonium surfactant, said surfactant being a C₁₄ alkylbenzyl, dimethyl ammonium chloride;

(d) an effective amount of alkali metal ethylenediaminetetraacetate builder; and

(e) the remainder as substantially all water;

the ratio of b;

d ranging from about 2;

1 to about 6.3;

1.

2. The hard surface cleaner of claim 1 wherein said solvent is an alkylene glycol ether which is selected from the group consisting of ethylene glycol monobutyl ether, ethylene glycol monopropyl ether, propylene glycol monopropyl ether, propylene glycol monobutyl ether, and mixtures thereof.

3. The hard surface cleaner of claim 2 wherein said solvent is ethylene glycol monobutyl ether.

4. The hard surface cleaner of claim 1 further including a nonionic surfactant other than the amine oxide.

5. The hard surface cleaner of claim 4 wherein said nonionic surfactant is an ethoxylated alcohol.

6. The hard surface cleaner of claim 1 further comprising a buffer selected from the group consisting of ammonium, alkali metal and alkaline earth metal hydroxides, alkali metal carbonates, alkali metal silicates, and mixtures thereof.

7. The hard surface cleaner of claim 6 wherein the buffer is alkali metal hydroxide.

8. A method of cleaning soil, without substantial residue remaining, from a hard surface comprising applying the cleaner of claim 1 to said soil and removing said soil and said cleaner.
