This invention provides water-based compositions, particularly coating, ink, fountain solution and agricultural compositions, manifesting reduced equilibrium and dynamic surface tension by the incorporation of a surface tension reducing amount of an acetylenic diol ethylene oxide/propylene oxide adduct of the structure:where r and t are 1 or 2, (n+m) is 1 to 30 and (p+q) is 1 to 30. Also disclosed is a method for making random and block EO/PO adducts of acetylenic diols by reacting an acetylenic diol with EO and/or PO in the presence of a trialkylamine or Lewis acid.

The flowability of stored triethylenediamine is improved by admixing with a flow promoting amount of a salt, amide or ester derivative of a C.sub.8 -C.sub.22 fatty acid. Especially suitable flow promoting additives for triethylenediamine are sales of stearic acid.
