Abstract (en)

[origin: WO2008095563A1] The invention relates to a phosphate-free dishwasher detergent which contains a builder, bleaching agents, and also a) a copolymer comprising i) monomers from the group of mono- or polyunsaturated carboxylic acids; ii) monomers of general formula R<SUP>1</SUP>(R<SUP>2</SUP>)C=C(R<SUP>3</SUP>)-X-R<SUP>4</SUP>, wherein R<SUP>1</SUP> to R<SUP>3</SUP> independently represent -H, -CH<SUB>3</SUB> or -C<SUB>2</SUB>H<SUB>5</SUB>, X represents an optional spacer group that is selected from -CH<SUB>2</SUB>-, -C(O)O- and -C(O)-NH-, and R<SUP>4</SUP> represents a straight-chain or branched saturated alkyl group with 2 to 22 carbon atoms or an unsaturated, preferably aromatic group with 6 to 22 carbon atoms; iii) optionally further monomers, b) a nonionic surfactant of general formula R<SUP>1</SUP>-CH(OH)CH<SUB>2</SUB>O-(AO)<SUB>w</SUB>-(A'O)<SUB>x</SUB>-(A''O)<SUB>y</SUB>- (A'''O)<SUB>z</SUB>-R<SUP>2</SUP>, wherein R<SUP>1</SUP> represents a straight-chain or branched, saturated or mono- or polyunsaturated C<SUB>6-24 </SUB>alkyl or -alkenyl group; R<SUP>2</SUP> represents a linear or branched hydrocarbon group with 2 to 26 carbon atoms; A, A', A'' and A''' independently represent a group selectected from -CH<SUB>2</SUB>CH<SUB>2</SUB>, -CH<SUB>2</SUB>CH<SUB>2</SUB>-CH<SUB>2</SUB>, -CH<SUB>2</SUB>-CH(CH<SUB>3</SUB>), -CH<SUB>2</SUB>-CH<SUB>2</SUB>-CH<SUB>2</SUB>-CH<SUB>2</SUB>, -CH<SUB>2</SUB>-CH(CH<SUB>3</SUB>)-CH<SUB>2</SUB>-, -CH<SUB>2</SUB>-CH(CH<SUB>2</SUB>-CH<SUB>3</SUB>), w, x, y and z represent values between 0.5 and 120, wherein x, y and/or z can be 0. The detergent according to the invention has good cleaning and rinsing results which are comparable to those of phosphate-containing dishwasher detergents or even outdo them.
