1. A reduced-phosphate or phosphate-free detergent or cleaner formulation comprising 1 to 50% by weight of at least one surfactant and from 0.1 to 50% by weight, based on said detergent or cleaner formulation of polyacetals obtained by cationically initiated polyaddition of(a) divinyl ethers and(b) dihydroxy compounds and also, optionally,(c) monohydroxy compounds, the molar ratio of (a):
- (b) being from 2;
1 to 1.001;
1 and the molar ratio of the vinyl ether groups in (a) to the sums total of the hydroxyl groups in (b) and (c) being from 2;
1 to 1;
1, said polyacetals having K values, determined by the method of H. Fikentscher at 25°
C. in tetrahydrofuran at a polyacetal concentration of 1% by weight, of from 8 to 100.
