Abstract

The invention relates to a liquid detergent or cleaning agent, comprising a) an anionic surfactant neutralized with an amine, b) an alkoxylated oxo alcohol having 7 or 8 alkoxy units, and c) up to 10 wt. %, relative to the entire detergent or cleaning agent, of water. The liquid detergent or cleaning agent has very good cleaning performance toward soiling containing fat and can be a component of water-soluble packagings.

First claim

The invention claimed is:

1. A liquid washing or cleaning agent comprising:
a) an anionic surfactant neutralized with an amine;
b) an alkoxylated oxo alcohol with 8 alkoxy units; and
c) up to about 10 wt. % water, based on the total washing or cleaning agent
wherein the washing or cleaning agent is packaged in a water-soluble covering.

2. The liquid washing or cleaning agent according to claim 1 , wherein the amine is chosen from choline, triethylamine, monoethanolamine, diethanolamine, triethanolamine, methylethylamine and mixtures thereof.

3. The liquid washing or cleaning agent according to claim 1 , wherein the anionic surfactant neutralized with an amine is chosen from neutralized alkylbenzenesulfonic acids, neutralized olefin sulfonic acids, neutralized C 12-18 alkanesulfonic acids, neutralized sulfuric acid monoesters with fatty alcohols, neutralized fatty acids, neutralized sulfuric acid monoesters with ethoxylated fatty alcohols and mixtures thereof.

4. The liquid washing or cleaning agent according to claim 1 , wherein the anionic surfactant neutralized with an amine is chosen form alkylbenzenesulfonic acids neutralized with monoethanolamine, fatty acids neutralized with monoethanolamine and mixtures thereof.

5. The liquid washing or cleaning agent according to claim 1 , wherein the alkoxylated oxo alcohol is C 13-15 oxo alcohols with 8 EO and mixtures thereof.

6. A water-soluble package containing a liquid washing or cleaning agent and a water-soluble envelope, wherein the liquid washing or cleaning agent comprises:
a) an anionic surfactant neutralized with an amine;
b) an alkoxylated oxo alcohol with 8 alkoxy units; and
c) up to about 10 wt. % water, based on the total washing or cleaning agent.

7. The water-soluble package according to claim 6 , wherein the water-soluble envelope comprises polyvinyl alcohol or a polyvinyl alcohol copolymer.

8. A method of cleaning a fat-containing soil from a cloth, the method comprising the step of applying a washing or cleaning agent to the soil on the cloth, the washing or cleaning agent comprising:
a) an anionic surfactant neutralized with an amine;
b) an alkoxylated oxo alcohol with 8 alkoxy units; and
c) up to about 10 wt. % water, based on the total washing or cleaning agent
wherein the washing or cleaning agent is packaged in a water-soluble covering.
