Low viscosity mixtures of (I) from 40 to 97.5% by weight of amphiphilic nonionic graft copolymers comprising, in copolymerized form, (a) at least 20% by weight of polyalkylene oxide units or polyvinylpyrrolidone units as hydrophilic part of the molecule and (b) at least 40% by weight of vinyl ester and/or (meth)acrylic ester units as hydrophobic part of the molecule, and (II) from 2.5 to 60% by weight of at least one viscosity-reducing additive selected from the group consisting of polyalkylene glycols, alkoxylated alcohols, alkoxylated alkylphenols, alkoxylated amines and hydroxy compounds having from 1 to 4 OH groups and from 2 to 10 carbon atoms, the molecular mass M N of the polymers in each case being not more than 2500, and (III) from 0 to 40% by weight of homogenizing or phase-stabilizing additives, for example water, monobasic and dibasic carboxylic acids having from 8 to 25 carbon atoms, fatty alcohol sulfates and fatty alcohol sulfonates or mixtures thereof, are useful as detergent and cleaner additives.
