Abstract
The invention includes lubricant concentrate and use solution compositions having an amine compound 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 saturated or unsaturated C.sub.6 -C.sub.18 alkyl, R.sub.2 is a linear or branched C.sub.1 -C.sub.8 alkyl, and R.sub.3 may be a linear or branched C.sub.1 -C.sub.8 alkyl. The concentrate also comprises an acidulant, optionally a stabilizing hydrotrope, and a surfactant. The lubricant use solution resulting from dilution of the concentrate has an amine compound in a concentration ranging from about 10 ppm to 10000 ppm. Also disclosed is a method of lubricating a conveyor system which includes providing a use solution of the lubricant concentrate composition.
