1. Dishwashing detergent, characterized in that it contains at least four nonionic surfactants A, B, C, and D, wherein
i. surfactant A is described by the general formula R1O(AlkO)xM(OAlk)yOR2, wherein
R1 and R2 independently of one another stand for a branched or unbranched, saturated or unsaturated, optionally hydroxylated alkyl group having 4 to 22 carbon atoms,Alk stands for a branched or unbranched alkyl group having 2 to 4 carbon atoms,x and y independently of one another stand for values between 1 and 70, andM stands for an alkyl group from the group CH2, CHR3, CR3R4, CH2CHR3, and CHR3CHR4, wherein R3 and R4 independently of one another stand for a branched or unbranched, saturated or unsaturated, cyclic or acyclic alkyl or alkenyl group having 1 to 18 carbon atoms; ii. surfactants B and C, which are different, are both described by the general formula R1O[CH2CH(CH3)O]x[CH2CH2O]y[CH2CH(CH3)O]zCH2CH(OH)R2, in which
R1 stands for a linear or branched aliphatic hydrocarbon group having 4 to 22 carbon atoms,R2 denotes a linear or branched hydrocarbon group having 2 to 26 carbon atoms,x and z stand for values between 0 and 40, andy stands for a value of at least 15; and iii. surfactant D is described by the general formula R1O[CH2CH(R3)O]x[CH2CHO]y[CH2CH(R4) O]zC(O)R2, wherein
R1 stands for a branched or unbranched alkyl group having 8 to 16 carbon atoms,R3 and R4 independently of one another stand for hydrogen or a branched or unbranched alkyl group having 1 to 5 carbon atoms,R2 stands for an unbranched alkyl group having 5 to 17 carbon atoms,x and z independently of one another stand for a value from 1 to 5, andy stands for a value from 13 to 35. |
