ABSTRACT:
A method for stabilizing organic metal finishing additives in aqueous metal treating baths by dissolving the organic metal finishing additive with a cyclodextrin and a common solvent therefor, so that an inclusion compound of the organic metal finishing additive in the cyclodextrin is formed, and then dissolving the inclusion compound in an aqueous metal treating bath. Aqueous metal treating baths having dissolved therein inclusion compounds of organic metal finishing additives in cyclodextrins are also described.
