PURPOSE:To provide an org. compsn. for a rust preventive agent which prevents corrosion of metal in moist air, water and above all, corrosive environment by incorporating >=1 kind of carboxylate and >=1 kind of oxine (deriv.) and N- lauroyl sarcosine. CONSTITUTION:A compsn. for a rust preventive agent contains 1-50wt% >=1 kind of the carboxylate expressed by the formula (component A) and 0.01- 5wt%, more particularly 0.05-2wt% >=1 kind of oxine (deriv.) and N-lauroyl sarcosine (compd. B). The compd. A is enumerated by, for example, n-C12H25 NH(CH2)2COONa and the oxine of the compd. B is enumerated by, for example, 8-oxyquinoline. Such compsn. for the rust preventive agent is constituted as the aq. soln. which is further added with an antiseptic such as salicylic acid, benzoic acid, lower alcohol such as methanol and ethanol, a solubilization agent selected from various surface active agents as well as perfume, dye, etc. and the balance water.
