ABSTRACT:
Corrosion prevention compositions which contain lactobionic acid N-alkylamides are described. In particular, lactobionic acid N-alkylamides in which the saturated or unsaturated alkyl group bonded via the amide function has a chain length of 8 to 18 carbon atoms show a good corrosion-inhibiting action. The use of lactobionic acid N-alkylamides in corrosion prevention compositions and metalworking compositions is also described.
