Benefits of technology
The present invention provides a corrosion inhibitor that is made of a mixture of three components: a food-grade ester, an alkane or paraffin, and an imidazoline. This mixture is safe for use in various environments that come into contact with foodstuffs. The composition can be used as a lubricant composition, with mineral oil being a preferred choice. The technical effect of this invention is to provide a safe and effective corrosion inhibitor for use in various industrial applications.
Problems solved by technology
Such contamination creates obvious difficulties and potential hazards.
However, because of the odor of the inhibitor, attributable to the ketone, this lubricant is no longer deemed food grade.

example i
[0041]This example illustrates the preparation of a corrosion inhibitor additive in accordance with the present invention. Into a suitable vessel equipped with stirring means is added the following at room temperature:
IngredientAmount, pbvISOPAR G4.0Methyl laureate1.0Imidazoline0.5
[0042]The above corrosion inhibitor composition is then admixed with 94.5 parts of white oil at ambient conditions. The resulting composition is useful as a transmission fluid.
example ii
[0043]This example illustrates the preparation of a lubricant composition in accordance herewith.
[0044]Into a suitable vessel equipped with a suitable stirrer is charged a quantity of white oil. To the white oil is added, serially, food grade corrosion inhibiting components to form a lubricant.

Abstract
A food grade corrosion inhibitor for admixture with a food-grade petroleum-based oil is derived from an admixture of food-grade components. The corrosion inhibitor, a food-grade isoalkane, a food-grade ester and imidazoline. The additive is incorporated into a lubricating component such as mineral oil, etc.
Description
BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention concerns corrosion inhibitors. More particularly, the present invention relates to corrosion inhibitors for use with lubricants. Even more particularly, the present invention concerns food grade corrosion inhibitors for use with lubricants and lubricants prepared therefrom. 2. Description of the Prior Art[0003]As is known to those skilled in the art, lubricants are used in practically every environment where two parts undesirably mesh or rub together to create friction. Thus, every conceivable type of machinery including, for example, vehicles, factory equipment, agricultural equipment, simple mechanical devices, such a lawn mowers, etc. all employ lubricants of some sort to minimize the wear and tear and to reduce friction.[0004]While each type of lubricant is selected according to the environment in which it is employed, petroleum-based oil compositions are the most popular and widely employed lu...
