Zusammenfassung:	Lecithin and 2-bromo-2-nitropropane -1,3 diol (BNPD) are used to inhibit corrosion in boiler steam condensate systems. Aqueous steam condensate corrosion inhibiting compositions of these components are also disclosed. BNPD is also used as a preservative in lecithin containing and in other generally regarded as safe (GRAS) additive containing compositions.
