Abstract
Abstract The invention relates to an aqueous detergent composition comprising (A) an alkali aluminum silicate, (B) an anionic surfactant, (C) an aliphatic monoalcohol of 5 to 18 carbon atoms or a C 8 -C 22 fatty acid/alkanolamine reaction product or an adduct of said compounds with an alkylene oxide, or an adduct of a C 8 -C 22 fatty acid, a trihydric to hexahydric aliphatic alcohol or an unsubstituted or substituted phenol with an alkylene oxide, and (D) an aqueous solution or dispersion of a polymer which contains carboxyl groups. This detergent composition is used for washing off prints or dyeings produced with reactive dyes on cellulosic fibre materials.
