Abstract

The aim of the invention is to improve the primary detergent power of washing and cleaning agents, in particular with respect to bleach-sensitive or enzyme-sensitive soiling. This is substantially achieved by the incorporation of alkoxy group-carrying sulfocalixarenes or carboxycalixarenes.

First claim

What is claimed is:

1 . A washing or cleaning agent, containing a compound of general formula (I)

in which n represents a number from 1 to 9, each R independently represents hydrogen or an alkyl group having 1 to 20 C atoms, each X independently represents hydrogen, —Y—COOM or —Y—SO 3 M, each Y independently represents a direct bond, an alkylene group having 1 to 12 C atoms, an arylene or heteroarylene group having 2 to 12 C atoms, a mono- or poly-alkyl-substituted arylene group or a mono- or poly-aryl-substituted alkylene group having 6 to 18 C atoms, and M represents hydrogen, an alkali metal atom or an ammonium group, wherein at least 1 substituent X is not hydrogen and that at least 1 substituent R is not hydrogen.

2 . The agent according to claim 1 , wherein it contains the compound of the general formula (I) in amounts of 0.1% by weight to 10% by weight.

3 . The agent according to claim 1 , wherein in the compound of general formula (I) n denotes a number from 3 to 7.

4 . The agent according to claim 1 , wherein in the compound of general formula (I) R denotes hydrogen or an alkyl group having 6 to 12 C atoms.

5 . The agent according to claim 1 , wherein in the compound of general formula (I) all substituents X are not hydrogen.

6 . A method for removing soiling from textiles or hard surfaces, comprising a step wherein the textiles or hard surfaces are contacted with a washing or cleaning agent and a compound of general formula (I)

in which n represents a number from 1 to 9, each R independently represents hydrogen or an alkyl group having 1 to 20 C atoms, each X independently represents hydrogen, —Y—COOM or —Y—SO 3 M, each Y independently represents a direct bond, an alkylene group having 1 to 12 C atoms, an arylene or heteroarylene group having 2 to 12 C atoms, a mono- or poly-alkyl-substituted arylene group or a mono- or poly-aryl-substituted alkylene group having 6 to 18 C atoms, and M represents hydrogen, an alkali metal atom or an ammonium group, wherein at least 1 substituent X is not hydrogen and that at least 1 substituent R is not hydrogen.

7 . The method according to claim 6 , wherein the compound of general formula (I) is added to a liquor containing washing or cleaning agent or is introduced into the liquor as a constituent of a washing or cleaning agent.

8 . The method according to claim 6 , wherein the concentration of the compound of general formula (I) in liquor containing the agent is in the range from 0.1 mmol/l to 2.5 mmol/l.

9 . The method according to claim 6 , wherein it is carried out by means of a domestic washing machine or dishwasher.
