Abstract

The invention relates to cleaning compositions comprising polyalkanolamine polymers. The present invention further relates to methods of cleaning dishware and hard surfaces using such cleaning compositions.

First claim

What is claimed is:

1. A cleaning composition which comprises a surfactant system and a polyalkanolamine polymer obtained by a process comprising step a), wherein
a) condensing component a1), which is triethanolamine,
wherein the sum of the amount of a1) is 100 wt. % in relation to the sum of the amount of all monomers employed in the condensation according to step a) in order to obtain a polyether having remaining hydroxyl groups and optionally remaining secondary amino groups, wherein the condensation in step a) occurs in the presence of 0.1% to 1% by weight of phosphoric acid at a temperature of from 180 to 240° C., wherein the condensation product has a viscosity in the range of 3,000 to 10,000 mPa S and has a number average molecular weight of from 1,000 to 15,000 g/mol, wherein the hydroxyl number of the resulting condensation products is from 300 to 1,000 g/mol, and
wherein the polyalkanolamine polymer is not alkoxylated.

2. A cleaning composition according to claim 1 wherein the cleaning composition is selected from the group consisting of hard surface cleaning compositions, liquid hand dishwashing compositions, solid automatic dishwashing compositions, liquid automatic dishwashing, and tab/unit dose form automatic dishwashing compositions.

3. A cleaning composition according to claim 1 wherein the detergent or cleaning composition comprises from about 0.05% to about 10% by weight of the detergent or cleaning composition, of the polyalkanolamine polymer.

4. A cleaning composition according to claim 1 wherein the surfactant system is selected from the group consisting of an anionic surfactant, cationic surfactant, nonionic surfactant, amphoteric surfactant, a zwitterionic surfactant, and mixtures thereof.

5. A cleaning composition according to claim 1 wherein the detergent or composition further comprises cleaning adjunct additives.

6. A method of cleaning dishware with a cleaning composition according to claim 1 , said method comprising the steps of applying the composition onto the dishware.

7. A method of cleaning a hard surface with a cleaning composition according to claim 1 , said method comprising the steps of applying the composition onto a hard surface.

8. A cleaning composition according to claim 1 wherein the detergent or cleaning composition comprises from about 0.15% to about 5% by weight of the detergent or cleaning composition, of the polyalkanolamine polymer.
