Abstract

The need for a liquid hard surface cleaning composition which provides reduced drying time is met by formulating the composition using copolymer comprising non-ionic monomeric units, a low level of cationic monomeric units, and other optional monomers.

First claim

What is claimed is:

1. A hard surface cleaning composition comprising a copolymer, wherein the hard surface composition comprises:
a) from about 0.1 to about 25 wt % of an ethoxylated non-ionic surfactant
b) from about 0.1 to about 7 wt % of the copolymer comprises:
i. from about 80 to about 90% by weight of at least one monoethylenically unsaturated polyalkylene oxide monomer of the formula I (monomer A)

 in which the variables have the following meanings:
X is —CO;
Y is —O—;
R 1 is hydrogen;
R 2 is ethylene, linear or branched propylene or mixtures thereof;
R 3 is methyl;
n is an integer from 20 to 50,

ii. from about 5 to about 20% by weight of at least one quaternized nitrogen-containing monomer, selected from the group consisting of at least one of the monomers of the formula IIa to IIc (monomer B)

 in which the variables have the following meanings:
R is C1-C4 alkyl or benzyl;
R′ is hydrogen or methyl;
Y —NH—;
A is C1-C6 alkylene;
X − is halide, C1-C4-alkyl sulfate, C1-C4-alkylsulfonate and C1-C4-alkyl carbonate,

iii. from about 1 to about 5% by weight of at least one anionic monoethylenically unsaturated monomer (monomer C), and
iv. from about 5 to about 20% by weight of at least one other non-ionic monoethylenically unsaturated monomer (monomer D),
wherein:
the weight ratio of Monomer A to Monomer B is from 3:1 to 5:1, the molar ratio of monomer B to monomer C is greater than about 1, the copolymer has a weight average molecular weight (Mw) from about 20,000 g/mol to about 500,000 g/mol,
and the copolymer and the non-ionic surfactant are present in a weight ratio of from about 0.03 to about 0.5, wherein the pH is from about 10.0 to about 11.

2. The hard surface cleaning composition according to claim 1 , wherein the weight ratio of monomer B to monomer C is greater than about 1.

3. The hard surface cleaning composition according to claim 1 wherein monomer B is a salt of 3-methyl-1-vinylimidazolium.

4. The hard surface cleaning composition according to claim 1 wherein monomer A is methylpolyethylene glycol (meth)acrylate.

5. The hard surface cleaning composition according to claim 1 wherein monomer A is methylpolyethylene glycol (meth)acrylate and wherein monomer B is a salt of 3-methyl-1-vinylimidazolium, and monomer D is N-vinylimidazole.

6. The hard surface cleaning composition according to claim 1 wherein the composition further comprises:
from about 0.05 wt % to about 6 wt % of the composition of amine oxide surfactant, and
from about 0.05 wt % to about 5 wt % of an anionic surfactant.

7. The hard surface cleaning composition according to claim 6 , wherein the composition comprises:
a) from about 0.05 to about 3 wt % of the copolymer;
b) from about 4.0 wt % to about 9.0 wt % of the non-ionic surfactant;
c) from about 0.1 wt % to about 4.5 wt % of the composition of amine oxide surfactant, and
d) from about 1.5 wt % to about 3.5 wt % of an anionic surfactant.

8. A method of improving shine of treated hard surfaces, the method comprising the following steps:
a) diluting a liquid hard surface cleaning composition of claim 1 ; and
b) applying the liquid hard surface cleaning composition to a hard surface.

9. The method according to claim 8 , subsequently comprising the step of rinsing.

10. The method according to claim 8 , wherein the liquid hard surface cleaning composition is sprayed onto the hard surface.

11. The method according to claim 8 , wherein the method also reduces the drying time of treated hard surfaces.
