ABSTRACT:
This invention provides water-based compositions, particularly coating, ink, and agricultural compositions, manifesting reduced equilibrium and dynamic surface tension by the incorporation of an effective amount of certain N,N-dialkyl urea compounds of the structure ##STR1## where R and R' are independently C1 to C6 alkyl or cycloalkyl with the sum of the carbon atoms in both R.sub.1 and R.sub.2 being 6 to 12.
