Abstract
Machine dishwashing detergents comprising builder(s), surfactant(s), and optionally further ingredients, and furthermore 0.1 to 50% by weight of one or more nonionic surfactants which, in 80% strength by weight solution in distilled water, have a viscosity (Brookfield, spindle 31, 30 rpm, 20° C.) of less than 450 mPas.
Claims27
A machine dishwashing detergent comprising one or more builders and 0.1 to 50% by weight of one or more nonionic surtactants that, in 80% strength by weight solution in distilled water, have a viscosity of less than 450 mPas, said nonionic surfactants comprising one or more surfactants of the general formula I:
- in which R1 is a straight-chain or branched, saturated or mono- or polyunsaturated C6-24-alkyl or -alkenyl radical;
- each group R2 and R3, independently of one another, is chosen from —CH3, —CH2CH3, —CH2CH2—CH3, CH(CH3)2 and the indices w, x, y, z, independently of one another, are integers from 1 to 6.
