Abstract:
An additive comprising one or more C 3 -C 12  hydroxycarboxylic acids and/or one or more C 3 -C 12  hydroxycarboxylic acid salts may be added to an aqueous system having galvanized metallurgy or a carbon steel surface in an effective amount to passivate a galvanized coating on the metallurgy or to decrease white rust formation or other types of corrosion upon the galvanized metallurgy or carbon steel surface in an aqueous system. In a non-limiting embodiment, the C 3 -C 12  hydroxycarboxylic acid or the C 3 -C 12  hydroxycarboxylic acid salt additive may utilize the zinc in the galvanized coating to achieve passivation. The passivation may occur while the system is shut down or in service. The aqueous system may be or include a cooling tower, a cooling water system, and combinations thereof. The additive may be used with or in the absence of a phosphorous-containing compound.

Claim (Index 2):
The method of  claim 1 , wherein the at least one hydroxycarboxylic acid is selected from the group consisting of saccharic acid, glycolic acid, tartaric acid, mucic acid, hydroxymalonic acid, gluconic acid, and combinations thereof.
