Abstract

The need for an antimicrobial hard surface cleaning composition which provides improved removal of greasy residues, especially greasy soap scum, is met by formulating the antimicrobial hard surface cleaning composition with an alkyl pyrrolidone surfactant and additional nonionic surfactant.

First claim

What is claimed is:

1. An antimicrobial liquid hard surface cleaning composition comprising:
(a) an alkylpyrrolidone surfactant, wherein the alkyl pyrrolidone is present at a level of from 0.1 to 10% by weight of the composition;
(b) additional nonionic surfactant, wherein the additional nonionic surfactant is present at a level of from 0.3% to 12% by weight of the antimicrobial liquid hard surface cleaning composition, and wherein the additional nonionic surfactant comprises alkoxylated nonionic surfactants and amine oxide nonionic surfactant, such that the antimicrobial liquid hard surface cleaning composition comprises:
(i) from 0.27% to 8.0% by weight of the antimicrobial liquid hard surface cleaning composition of alkoxylated nonionic surfactant; and
(ii) from 0.03% to 4.0% by weight of the composition of amine oxide surfactant;

(c) an antimicrobial agent; and
(d) a polyethyleneimine polymer;
wherein the liquid hard surface cleaning composition has a pH of greater than 4.0.

2. The antimicrobial liquid hard surface cleaning composition according to claim 1 , wherein the alkyl pyrrolidone is a C5-C12 alkyl pyrrolidone.

3. The antimicrobial liquid hard surface cleaning composition according to claim 1 , wherein the antimicrobial agent is selected from the group consisting of: quaternary ammonium compounds and mixtures thereof.

4. The antimicrobial liquid hard surface cleaning composition according to claim 1 , wherein the antimicrobial liquid hard surface cleaning composition comprises the antimicrobial agent at a level of from 0.01 to 2.0% by weight of the antimicrobial liquid hard surface cleaning composition.

5. The antimicrobial liquid hard surface cleaning composition according to claim 1 , wherein the antimicrobial liquid hard surface cleaning composition comprises polycarboxylated surfactant.

6. The antimicrobial liquid hard surface cleaning composition according to claim 5 , wherein the polycarboxylated surfactant is present at a level of from 0.05% to 5% by weight of the antimicrobial liquid hard surface cleaning composition.

7. The antimicrobial liquid hard surface cleaning composition according to claim 1 , wherein the polyethyleneimine polymer is present at a level of from 0.005% to 2.0% by weight of the total antimicrobial liquid hard surface cleaning composition.

8. The antimicrobial liquid hard surface cleaning composition according to claim 1 , wherein the antimicrobial liquid hard surface cleaning composition further comprises a chelant, selected from the group consisting of: amino-carboxylates carboxylated fructan, phosphonate chelating agents, and mixtures thereof.

9. The antimicrobial liquid hard surface cleaning composition according to claim 8 , wherein the antimicrobial liquid hard surface cleaning composition comprises the chelant at a level of from 0.025% to 5.0% by weight of the antimicrobial liquid hard surface cleaning composition.

10. The antimicrobial liquid hard surface cleaning composition according to claim 1 , wherein the composition has a pH of from 4.0 to 13 measured on the neat antimicrobial liquid hard surface cleaning composition, at 25° C.
