Polyesters obtainable by condensation of (a) an at least dicarboxylic acid, or an ester or anhydride or a mixture thereof, (b) an at least dihydric alcohol or an addition product of from 1 to 5 mol of at least one alkylene oxide of 2 or 3 carbon atoms with 1 mol of an at least dihydric alcohol, or a mixture thereof, and (c) a water-soluble addition product of from 5 to 80 mol of at least one alkylene oxide with 1 mol of a C8-C24-alcohol, a C8-C18-alkylphenol or a C8-C24-alkylamine in a molar ratio of (a):(b):(c) of 100:(25-2500):(5-110) at not less than 120 DEG C. up to a weight average molecular weight of from 2000 to 50000, are used in amounts of from 0.05 to 15% by weight as grayness inhibitors and soil release promoters in detergents. |
