Abstract

The need for a liquid hard surface cleaning composition which provides improved shine, reduced slipperiness during drying, and also improved drying times is met formulating the composition using a ethoxylated alkoxylated nonionic surfactant, in combination with a detersive surfactant.

First claim

What is claimed is:

1. A method of improving shine, or reducing drying time of a hard surface, comprising the steps of:
diluting a liquid hard surface cleaning composition comprising an ethoxylated alkoxylated nonionic surfactant, amine oxide, and an anionic surfactant, to a dilution level of from about 0.1% to about 2% by volume, wherein the ethoxylated alkoxylated nonionic surfactant is an alkyl ethoxy alkoxy alcohol of formula (II):

wherein:
R is a branched or unbranched alkyl radical having about 8 to about 16 carbon atoms;
R 1 is a branched or unbranched alkyl radical having about 1 to about 5 carbon atoms;
n is a number from about 1 to about 10; and
m is a number from about 6 to about 35

and the ethoxylated alkoxylated nonionic surfactant provides a wetting effect of from about 60 to about 200, the wetting effect being measured according to EN 1772, using about 1 g/l of the ethoxylated alkoxylated nonionic surfactant in distilled water, at about 23° C., with about 2 g soda/l, and

(b) applying the diluted composition to a hard surface.

2. The method of claim 1 , comprising the further step of:
(c) rinsing the hard surface with water.

3. The method of claim 1 , wherein the hard surface is selected from the group consisting of: floors, walls, tiles, windows, cupboards, sinks, showers, shower plastified curtains, wash basins, water closet, fixtures and fittings, appliances, and combinations thereof.

4. A method of improving shine, or reducing drying time of a hard surface, comprising the steps of:
diluting a liquid hard surface cleaning composition comprising:
a. from 0.01 wt. % to 10 wt % of an esterified alkyl alkoxylated surfactant of formula (I):

wherein:
R is a branched or unbranched alkyl radical having about 8 to about 16 carbon atoms;
R 3 , R 1 independently of one another, are hydrogen or a branched or unbranched alkyl radical having about 1 to about 5 carbon atoms;
R 2 is an unbranched alkyl radical having about 5 to about 17 carbon atoms;
l, n independently of one another, are a number from about 1 to about 5; and
m is a number from about 8 to about 50;

b. an additional nonionic surfactant blend comprising an alkyl ethoxylated alcohol and amine oxide, wherein the alkyl ethoxylated alcohol is present in the liquid hard surface cleaning composition at about 1.0 wt % to about 10.0 wt %, based on the weight of the liquid hard surface cleaning composition, and the amine oxide is present in the liquid hard surface cleaning composition at about 0.05 wt % to about 6 wt %, based on the weight of the liquid hard surface cleaning composition, wherein the esterifield alkyl alkoxylated surfactant and the additional nonionic surfactant blend are present in a weight ratio of from 0.03 to 0.5; and
c. from about 0.05 wt % to about 5 wt % of an anionic surfactant, based on the weight of the liquid hard surface cleaning composition; and

applying the diluted composition to a hard surface.

5. The method of claim 4 , wherein the hard surface is selected from the group consisting of: floors, walls, tiles, windows, cupboards, sinks, showers, shower plastified curtains, wash basins, water closet, fixtures and fittings, appliances, and combinations thereof.
