The invention is a lubricant concentrate composition, use solution, and method of use. The lubricant includes amine compounds of the formula R1 - O - R2 - NH2, R1 - O - R2 - NH - R3 - NH2, and mixtures thereof, wherein R1 may be a linear C6-C18 alkyl, R2 may be a linear or branched C1-C8 alkyl, and R3 may be a linear C1-C8 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.

L'invention concerne une composition concentré de lubrifiant, une solution d'utilisation et un procédé d'utilisation. Le lubrifiant comprend des composés amine de la formule R¿1? - O - R¿2? - NH¿2?, R¿1? - O - R¿2? - NH - R¿3? - NH¿2?, et des mélanges de ceux-ci, formule dans laquelle R¿1? peut représenter akyle C¿6?-C¿18? linéaire, R¿2? peut représenter un akyle C¿1?-C¿8? linéaire ou ramifié et R¿3? peut représenter un alkyle C¿1?-C¿8? linéaire, ainsi qu'un inhibiteur de corrosion. La composition de lubrifiant comprend de préférence un acide polycarboxylique ainsi qu'un inhibiteur de corrosion. La composition peut également comprendre un hydrotrope, un stabilisant et un tensio-actif destiné à conférer une détergence à la composition lors de sa dilution et de son utilisation. L'invention concerne également une solution d'utilisation de lubrifiant résultant de la dilution de ce concentré.
