Abstract

An aqueous cleaning composition comprising: (a) from 0.01 to 0.5% by weight of the composition of a grease loosening system comprising: i) 50% or more by weight of the system of a low emulsifying surfactant wherein the low emulsifying surfactant is a nonionic ethoxylate having an HLB value of from about 13 to about 20; and ii) 50% or less by weight of the system of a high emulsifying material wherein the high emulsifying material is selected from the group consisting of nonionic surfactant having an HLB value of less than 13, a surfactant other than nonionic surfactants; antimicrobial quats and mixtures thereof; (b) a shine polymer comprising at least one monomer comprising a substantially planar 5-7 membered ring, said monomer preferably being selected from the group consisting of vinylpyrrolidone, vinylimidazoline, maleimide, styrene sulfonate and vinylcaprolactam; and (c) optionally a non-quaternary ammonium compound antimicrobial agent.

Claims (30)

1. An aqueous cleaning composition comprising:

(a) from about 0.01 to about 0.5% by weight of the composition of a grease loosening system comprising:

i) 50% or more by weight of the system of a low emulsifying surfactant wherein the low emulsifying surfactant is a nonionic ethoxylate having an HLB value of from about 13 to about 20; and

ii) 50% or less by weight of the system of a high emulsifying material wherein the high emulsifying material is selected from the group consisting of nonionic surfactant having an HLB value of less than 13, a surfactant other than nonionic surfactants; antimicrobial quaternary ammonium compounds and mixtures thereof, wherein the quaternary ammonium compound is present in an amount of from about 0.01% to about 0.50% by weight of the aqueous cleaning composition; and

(b) a shine polymer comprising a first vinyl pyrrolidone monomer of chemical structure

wherein R1 and R2 are independently H, or a C1-C6 hydrocarbon chain, and where x is from about 50 to about 100,000; and

a second monomer of chemical structure

wherein R=CH 3 , Z=NH, N—CH 3 , m=1-4, R 1 and R 2 are CH 3 , R 3 is H, y is from about 10 to about 10,000, and X is a counter-ion.

2. A composition according to claim 1 further comprising a non-quaternary ammonium compound antimicrobial agent.

3. A composition according to claim 1 wherein the grease loosening system comprises 70% or more by weight of the system of the low emulsifying surfactant and 30% or less by weight of the system of the high emulsifying material.

4. A composition according to claim 1 wherein the nonionic ethoxylate of the low emulsifying surfactant has an HLB value of from about 14 to about 18.

5. A composition according to claim 1 wherein the nonionic ethoxylate of the low emulsifying surfactant comprises a material selected from the group consisting of polyethylene glycols, alcohol ethoxylate surfactants, ethoxylated polyols esterified with fatty acids, EO-PO block copolymers, polyols of ethylene diamine, and mixtures thereof.

6. A composition according to claim 1 wherein the nonionic ethoxylate of the low emulsifying surfactant comprises a mixture of a non-ionic ethoxylate surfactant with an HLB value of from about 13 to about 15.5 and a polyethylene glycol or methyl capped polyethylene glycol.

7. A composition according to claim 1 wherein the nonionic ethoxylate of the low emulsifying surfactant comprises a mixture of a non-ionic ethoxylate surfactant with an HLB value of from about 13 to about 15.5 and a polyethylene glycol or methyl capped polyethylene glycol in a weight ratio of from about 5:1 to about 1:5.

8. A composition according to claim 1 wherein the nonionic ethoxylate of the low emulsifying surfactant comprises a mixture of an alcohol ethoxylate surfactant having an HLB value of from about 13 to about 15.5 and an ethoxylate polyol esterified with fatty acid.

9. A composition according to claim 1 wherein the nonionic ethoxylate of the low emulsifying surfactant comprises a mixture of an alcohol ethoxylate surfactant having an HLB value of from about 13 to about 15.5 and polyoxyethylene (20) sorbitan monolaurate, in a weight ratio of from about 5:1 to about 1:5.

10. A composition according to claim 1 wherein the high emulsifying material is selected from the group consisting of amine oxide, non-ionic surfactant having an HLB below 13, alkyl polyglucosides and mixtures thereof.

11. A composition according to claim 1 comprising:

(a) from about 0.05% to about 0.5% by weight of the grease loosening system;

(b) from about 0.005% to about 0.5% by weight of the composition of the shine polymer;

(c) from 0.01 to about 0.25% by weight of the composition of the antimicrobial quaternary ammonium compound; and

(d) from about 90 to about 99% by weight of the composition of water.

12. A composition according to claim 1 further comprising a soil entrainment polymer wherein the soil entrainment polymer is selected from the groups consisting of polymer flocculants and coagulants.

13. A composition according to claim 1 further comprising a soil entrainment polymer wherein the soil entrainment polymer has a molecular weight greater than 500,000 and chemical structure:

wherein weight ratio y/z is from about 1:5 to about 5:1.

14. A composition according to claim 1 further comprising ethanol or isopropanol solvent and a fragrance.

15. An article treated with a composition according to claim 1 wherein the article is in the form of a disposable or partially reusable substrate comprising one or more nonwoven layers and wherein the substrate has a load factor of from about 3 times to about 10 times of solution per gram of nonwoven substrate.

16. A method of cleaning a hard surface comprising the steps of:

(a) contacting the surface with a composition according to claim 1 ; and

(a) wiping the surface.
