PURPOSE: Provided are water-based compositions containing an organic or inorganic compound, particularly aqueous organic coating, ink, adhesive, fountain solution, agricultural and electronics cleaning compositions, having reduced equilibrium and dynamic surface tension by incorporation of an effective amount of an N,N,N'-trialkyl urea. CONSTITUTION: In a method for applying a coating of a water-based composition to a surface to partially or fully coat the surface, the composition contains an inorganic or organic compound and an effective amount of a surfactant for reducing the dynamic surface tension of the composition, the improvement which comprises employing as the surfactant a trialkyl urea of the structure where R1 and R2 are C2 to C6 alkyl groups, R3 is methyl or ethyl, and the total number of carbon atoms in R1, R2 and R3 is from 6 to 14.
