Abstract

Compositions and methods to improve the cleaning performance of washing agents during laundering of textiles are disclosed. Compositions described use 6-desoxy-6-amino-celluloses. Methods for laundering textiles, in which a detergent and a soil release active ingredient are used in the form of a cellulose derivative as defined above, are also included. These methods can be performed manually or as appropriate with the aid of a conventional domestic washing machine.

Claims

1. A detergent, comprising a cellulose derivative selected from the group consisting of ω

-methoxyethylamino cellulose and ω

-methoxyethyl methyl amino cellulose and wherein the detergent further comprises from 2 wt. % to 25 wt. % of a synthetic anionic surfactant, from 1 wt. % to 30 wt. % nonionic surfactant, and from 0.1 wt. % to 5 wt. % of saturated fatty acid soap.

2. The detergent according to claim 1, wherein it comprises the cellulose derivative in amounts of from 0.05 wt. % to 10 wt. %.

3. A method for laundering textiles, comprising a step wherein the detergent according to claim 1 is contacted with textiles in a washing liquor.

4. The method according to claim 3, wherein the concentration at which the cellulose derivative is used in the washing liquor is 0.0001 g/L to 1 g/L.

5. The method according to claim 4, wherein the concentration at which the cellulose derivative is used in the washing liquor is 0.001 g/L to 0.2 g/L.
