## Abstract

The present invention relates to a process of treating a hard surface with a composition comprising polyalkoxylate trisiloxane. More specifically, it relates to a process of treating an inclined or vertical hard surface, wherein a composition comprising polyalkoxylate trisiloxane is applied onto said hard surface.

## Claims

### Claim 1

A process of treating a inclined or vertical hard surface comprising the step of applying a liquid composition onto said hard surface, wherein said composition comprises, by total weight:
a. 0.1% to 0.5% of a polyalkoxylate trisiloxane having the formula (I):
(CH3)3Si—O(CH3)Si[(CH2)3—O—(CH2CH2O)4(CH2CH2CH2O)2H]—O—Si(CH3)3 (I);
b. 1% to 5% of an additional nonionic surfactant;
c. 1% to 5% of an anionic surfactant;
d. a water soluble or water dispersible co-polymer;
e. 0.01% to 5.0% of a chelating agent;
f. 0.2% to 0.8% of a fatty acid; and
g. 0.1 to 6% of a base.

### Claim 2 (depends on 1)

The process according to claim 1 wherein said composition is sprayed a onto said hard surface.

### Claim 3 (depends on 1)

The process according to claim 1 wherein the liquid composition has a pH above 9.

### Claim 4 (depends on 1)

The process according to claim 1 wherein said polyalkoxylate trisiloxane is present in the liquid composition in an amount of 0.5% of the total weight of the present invention.

### Claim 5 (depends on 1)

The process according to claim 1 wherein the liquid composition further comprises one or more ingredient selected from the group consisting of surfactants, builders, chelants, polymers, buffers, bactericides, preservatives, hydrotropes, stabilisers, radical scavengers, bleaches, bleach activators, soil suspenders, anti dusting agents, dispersants, pigments, silicones, perfumes, dyes and a mixture thereof.

### Claim 6 (depends on 1)

The process according to claim 1 wherein the liquid composition further comprises additional surfactants selected from the group consisting of an anionic surfactant, a non-ionic surfactant, a zwiterrionic surfactant, an amphoteric surfactant and a mixture thereof.

### Claim 7 (depends on 1)

The process according to claim 1 which further comprises the steps of leaving said composition on said hard-surface to act, optionally wiping said hard-surface, and then rinsing said hard-surface.

### Claim 8

A liquid composition comprising, by total weight:
a. 0.1% to 0.5% of a polyalkoxylate trisiloxane having a molecular weight of max 1000 and the formula (II):
(CH3)3Si—O(CH3)Si[(CH2)3—O—(CH2CH2O)4(CH2CH2CH2O)2H]—O—Si(CH3)3 (II)
b. 1% to 5% of an additional nonionic surfactant;
c. 1% to 5% of an anionic surfactant;
d. a water soluble or water dispersible co-polymer;
e. 0.01% to 5.0% of a chelating agent;
f. 0.2% to 0.8% of a fatty acid; and
g. 0.1 to 6% of a base,
wherein said composition is packaged in a spray dispenser.

### Claim 9 (depends on 8)

A liquid composition packed in a spray-type container according to claim 8 wherein said composition has a pH above 9.

### Claim 10 (depends on 8)

A method for obtaining good clinging and sheeting effect on inclined or horizontal hard surface comprising providing the composition according to claim 8 to said hard surface.

### Claim 11 (depends on 8)

A method for obtaining good filming and/or streaking performance, good shine performance, as well as good next time cleaning benefit performance on inclined or horizontal hard surface comprising providing the composition according to claim 8 to said hard surface.
