Abstract
The invention relates to amphiphilic, non-ionic oligoesters that are free-flowing at an ambient temperature. Said oligoesters are produced by reacting dicarboxylic acid compounds, polyol compounds of water-soluble alkylene oxide addition products and optionally diol compounds. The invention also relates to detergent formulations and concentrates containing the aforementioned oligoesters and the use of oligoesters as additives in detergents, in particular for cleaning hard surfaces.
Claims10
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 C2- to C4-alkylene oxides and a C1- to C6-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.
