Zusammenfassung:	A composition for the conditioning of water for industrial use, especially boiler feed water is disclosed which is added to the water for inhibiting scale deposit and corrosion, especially in high duty once-through forced-circulation boilers working at pressures above 150 bar and temperatures above 500 DEG C. The composition contains until 30% of a long-chain aliphatic polyamine, until 70% of ethanolamine, and until 40% of an alkyl substituted arylsulfonic acid salt or amide from which until 90% may be replaced by cyclohexylamine. The compositions are heat resistant under the above mentioned conditions of use and display outstanding effects against scale deposit and against corrosion of steel under severe conditions. They are limpid, homogeneous preparations and may be diluted with water in any ratio.
