Abstract
A corrosion inhibitor system and method for inhibiting corrosion in aqueous compositions within aerosol containers. The composition comprises at least one Group I metal salt of benzoic acid and at least one phytate selected from the group consisting of Group I and Group II metal salts of phytic acid and mixtures thereof, when the ratio of benzoate to phytate is about 10:1 to 1:10 and preferably 2.5:1, the corrosion inhibitor system being present in an amount of about 0.1 to 4% by weight of the composition. The method comprises adding an effective amount of at least one Group I metal salt of benzoic acid and at least one phytate selected from the group consisting of Group I and Group II metal salts of phytic acid and mixtures thereof to reduce corrosion in steel aerosol containers containing corrosive aqueous compositions. The ratios of benzoate to phytate are effective to inhibit corrosion in the aqueous system.
