Abstract
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 GRAS additive containing compositions.
