Abstract

A cleaning composition for sanitizing and/or disinfecting hard surfaces, comprising: a cationic biocide, surfactant and low levels of VOC solvents. The cleaning composition is adapted to clean a variety of hard surfaces without leaving behind a visible residue and creates low levels of streaking and filming on the treated surface. The cleaning composition contains less than 5% by weight of VOCs. The cleaning composition may be used alone as a liquid or spray formulation or in combination with a substrate, for example, a pre-loaded cleaning wipe.

First claim

We claim:

1. A cleaning composition consisting of:
i. about 0.05-5% by weight of one or more cationic biocide,
ii. about 0.01-5% by weight of one or more nonionic surfactant,
iii. about 0.05-5% by weight of a first solvent comprising an ethylene glycol ether,
iv. about 0.01-2% by weight of a second solvent selected form the group consisting of: methanol, ethanol, isopropanol, propanol, butyl alcohol, sec-butyl alcohol, isobutyl alcohol, tert-butyl alcohol, pentyl alcohol, tert-pentyl alcohol, 2-pentanol, 3-pentanol, neopentyl alcohol, diols, C1-10 alkyl ethers of alkylene glycols, polyalkylene glycols, short chain carboxylic acids, short chain esters, isoparaffinic hydrocarbons, mineral spirits, alkylaromatics, terpenes, terpene derivatives, terpenoids, terpenoid derivatives, formaldehyde, pyrrolidones, and any mixtures or combinations thereof;
v. at least 80% by weight of water; and
vi. optionally, one or more adjuncts selected from the group consisting of: buffers, fragrances, perfumes, builders, defoamers, hydrotropes, enzymes, bleaching agents, and preservatives.

2. The cleaning composition as defined in claim 1 , wherein the buffer is present.

3. The cleaning composition as defined in claim 1 , wherein the fragrance is present.

4. The cleaning composition as defined in claim 1 , wherein said second solvent comprises isopropanol.

5. The cleaning composition as defined in claim 1 , wherein said nonionic surfactant comprises a surfactant containing ethylene oxide and propylene oxide groups.

6. The cleaning composition as defined in claim 1 , wherein said nonionic surfactant is selected from the group consisting of: ethoxylate surfactants, propoxylate surfactants, ethoxylate-propoxylate copolymer surfactants and any mixtures or combinations thereof.

7. The cleaning composition as defined in claim 1 , wherein said cationic biocide includes a quaternary ammonium compound.

8. The cleaning composition as defined in claim 1 , wherein said nonionic surfactant is selected from the group consisting of: ethoxylated alcohols, propoxylated alcohols, an ethoxylated/propoxylated alcohol, ethylene oxide and mixed ethylene oxide/propylene oxide adducts of alkylphenols, the ethylene oxide and mixed ethylene oxide/propylene oxide adducts of fatty acids, mixed ethylene oxide/propylene oxide block copolymers, and any mixtures or combinations thereof.

9. A cleaning composition consisting of:
i. about 0.05-5% by weight of one or more quaternary ammonium compound,
ii. about 0.01-5% by weight of one or more non-ionic surfactant comprising: at least one surfactant containing ethylene oxide and propylene oxide groups, and
iii. about 0.05-5% by weight of a first solvent comprising an ethylene glycol ether,
iv. about 0.01-2% by weight of a second solvent selected form the group consisting of: methanol, ethanol, isopropanol, propanol, butyl alcohol, sec-butyl alcohol, isobutyl alcohol, tert-butyl alcohol, pentyl alcohol, tert-pentyl alcohol, 2-pentanol, 3-pentanol, neopentyl alcohol, diols, C1-10 alkyl ethers of alkylene glycols, polyalkylene glycols, short chain carboxylic acids, short chain esters, isoparaffinic hydrocarbons, mineral spirits, alkylaromatics, terpenes, terpene derivatives, terpenoids, terpenoid derivatives, formaldehyde, pyrrolidones, and any mixtures or combinations thereof;
v. at least 80% by weight of water; and
vi. optionally, one or more adjuncts selected from the group consisting of: fragrances, perfumes, buffers, builders, defoamers, hydrotropes, enzymes, bleaching agents, and preservatives.

10. The cleaning composition as defined in claim 9 , wherein the buffer is present.

11. The cleaning composition as defined in claim 9 , wherein the fragrance is present.

12. The cleaning composition as defined in claim 9 , wherein the composition comprises at least 90% by weight of water.

13. The cleaning composition as defined in claim 9 , wherein said non-ionic surfactant further comprises a surfactant that is selected from the group consisting of: ethoxylate surfactants, propoxylate surfactants, ethoxylate-propoxylate copolymer surfactants and any mixtures of combinations thereof.

14. The cleaning composition as defined in claim 9 , wherein said second solvent comprises isopropanol.

15. A cleaning composition consisting of:
i. about 0.05-5% by weight of one or more cationic biocide comprising at least one quaternary ammonium compound,
ii. about 0.01-5% by weight of one or more non-ionic surfactant selected from the group consisting of: ethoxylate surfactants, propoxylate surfactants, ethoxylate-propoxylate copolymer surfactants, ethoxylated alcohol, propoxylated alcohol, an ethoxylated/propoxylated alcohol, ethylene oxide and mixed ethylene oxide/propylene oxide adducts of alkylphenols, the ethylene oxide and mixed ethylene oxide/propylene oxide adducts of fatty acids, mixed ethylene oxide/propylene oxide block copolymers, and any mixtures or combinations thereof;
