Abstract
The invention is a lubricant concentrate composition, use solution, and method of use. The lubricant includes amine compounds of the formula, EQU R.sub.1 --O--R.sub.2 --NH.sub.2, EQU R.sub.1 --O--R.sub.2 --NH--R.sub.3 --NH.sub.2, and mixtures thereof wherein R.sub.1 may be a linear C.sub.6 -C.sub.18 alkyl, R.sub.2 may be a linear or branched C.sub.1 -C.sub.8 alkyl, and R.sub.3 may be a linear C.sub.1 -C.sub.8 alkyl, and a corrosion inhibitor. The lubricant composition preferably includes a polycarboxylic acid as a corrosion inhibitor. The composition may also include a hydrotrope, stabilizer, and a surfactant to provide detergency to the composition upon dilution and use. The invention also includes a lubricant use solution resulting from dilution of this concentrate.
