    Abstract: Corrosion inhibitors for aqueous media comprise a triazole, an alkali metal borate, benzoate, and silicate and an alkali metal salt of a C.sub.7 to C.sub.13 dibasic acid. They may be used in antifreeze compositions for motor vehicles. Since neither nitrites and amines are required the danger of forming toxic nitrosamines by the reaction of these materials is overcome.
