Claim:
Amphiphilic, non-ionic oligoesters consisting essentially of the polycondesnation product of (A) from 20 to 50 mole % of one or more dicarboxylic acid compounds, (B) 10.1 to 29.9 mole % of one or more polyol compounds with at least three OH-groups, (C) 10.1 to 50 mole % of one or more water-soluble alkylene oxide addition products of one or more C 2 - to C 4 -alkylene oxides and a C 1 - to C 6 -alcohol in a ratio of 4 to 100 moles of alkylene oxide to 1 mole of alcohol, and (D) 0.1 to 30 mole % of a diol selected from the group consisting of ethylene glycol, 1,2-propylene glycol, 1,3-propylene glycol, neopentylglycol, 1,2-butylene glycol, 3-methoxy-1,2-propylene glycol, dimers and trimers thereof and mixtures thereof, said oligoesters being free-flowing at ambient temperatures between 15–25°C.
