ABSTRACT:
Scale formation as well as deposition of incrustations in aqueous systems are prevented by the addition of a monophosphoric acid ester of a hydroxy alkyl urea compound or of salts of such an ester. Preferred esters of this type are the esters obtained by reacting hydroxyl alkyl urea compounds with urea phosphate. The esters are highly effective even when they are added in substoichiometric amounts calculated with respect to the scale and hardness causing compounds present in aqueous systems.
