    Urea forms solid adducts with a wide range of liquid organic molecules. Many surfactant molecules are the right size and conformation to form adducts. A typical urea adduct can contain 40–60% surfactant and secondary components. Ethoxylated alcohols show great promise because they are good wetting agents and have already proven themselves as adjuvants. These liquid surfactants can be transformed into free-flowing, solid urea complexes which are highly effective in actual field trials.
