Description

technical field

[0001] The present invention relates to the field of alkoxylated aromatic polycarboxylic acid amides and methods for their preparation. The alkoxylated aromatic polycarboxylic acid amides can be advantageously used as anti-redeposition agents in washing applications. Background technique

[0002] Anti-redeposition agents used in laundry detergents help prevent soils from settling on fabrics after they have been removed during laundering. This can be achieved, for example, by dispersing the soil in the wash liquid.

[0003] Laundering soiled fabrics with laundry detergent compositions is essentially a two-step process. In the first stage, the detergent must remove the soil from the fabric and suspend it in the wash liquor. In the second stage, the detergent composition must prevent the redeposition of soils and other insoluble materials on the fabric prior to removal of the fabric from the wash liquor or rinse liquor. Polymers are known to assist both proc...
