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.sub.8 -C.sub.22 fatty acid/alkanolamine reaction product or an adduct of said compounds with an alkylene oxide, or an adduct of a C.sub.8 -C.sub.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.
Claims21
An aqueous detergent composition comprising
- (A) 20 to 60% by weight of an alkali aluminum silicate,
- (B) 0.5 to 20% by weight of an anionic alkylene oxide polyadduct of the formula
- Y--O--(CH.sub.2 CH.sub.2 O).sub.m --X
- wherein Y is alkyl or alkenyl, each of 8 to 22 carbon atoms, alkylphenyl containing 4 to 16 carbon atoms in the alkyl moiety, or o-phenylphenyl, m is 2 to 40, and X is the acid radical of an inorganic oxygen-containing acid, or is the radical of an organic acid, said acid radical X being in the form of the free acid or its salt,
- (C) 1 to 20% by weight of an aliphatic monoalcohol of 5 to 18 carbon atoms or a C.sub.8 -C.sub.22 fatty acid/alkanolamine reaction product or an adduct of said compounds with an alkylene oxide, or an adduct of C.sub.8 -C.sub.22 fatty acid, a trihydric to hexahydric aliphatic alcohol or an unsubstituted or substituted phenol with an alkylene oxide, and
- (D) 2 to 30% by weight of an aqueous solution or dispersion of a polymer which contains carboxyl groups, in the substantial absence of chelating phosphorous compounds, electrolytes, ion exchangers and/or other chelating agents.
A detergent composition according to claim 8, wherein component (D) is a 1.5 to 3% aqueous solution of a macromolecular copolymer of ethylene and maleic anhydride in the molar ratio of 1:1, based on the copolymer.
