Abstract: The invention relates to the use of substituted diureas, polyureas, bisurethanes, or polyurethanes of the formula R
1 X-CO-NR
3 R
4 , in which X represents R
2 N or O, and R
1 to R
4 represent hydrogen, alkyl groups, alkenyl groups, cycloalkyl groups, aryl groups, or aryl-alkyl groups independently of one another, wherein at least one variable must represent a group with at least four carbon atoms and the urea or urethane functionality must be present multiple times via bridge elements, in order to improve the use properties of mineral and synthetic nonaqueous industrial liquids.

Abstract: The invention relates to the use of substituted monoureas, diureas, polyureas, monourethanes, bisurethanes, or polyurethanes of the formula R
1 X-CO-NR
3 R
4 , in which X represents R
2 N or O, and R
1 to R
4 represent hydrogen, alkyl groups, alkenyl groups, cycloalkyl groups, aryl groups, or aryl-alkyl groups independently of one another, wherein at least one variable must contain four carbon atoms and the urea or urethane functionality can be present multiple times via bridge elements, in order to further improve the cold flow properties of mineral oils and crude oils which already contain an additional organic compound that is suitable for dispersing or aiding the dispersion of paraffin crystals precipitated at low temperatures and an additional organic compound that improves the cold flow behavior of mineral oils and crude oils.
