Lubricant concentrate and an aqueous lubricant solution based on fatty amines, a process for its production and its use

A lubricant concentrate comprising from about 1 to about 40% by weight of at least one polyamine compound of formula (I):

• R--A--(CH.sub.2).sub.k --NH--((CH.sub.2).sub.1 --NH).sub.y --(CH.sub.2).sub.m --NH.sub.2.(H.sup.+ X.sup.-).sub.n (I)
• in which
• R is a substituted or unsubstituted, linear or branched, saturated or mono- or polyunsaturated C.sub.6-22 alkyl radical, the substituents being selected from amino, imino, hydroxy, halogen and carboxy, or a substituted or unsubstituted phenyl radical, the substituents being selected from amino, imino, hydroxy, halogen, carboxy and linear or branched, saturated or mono- or polyunsaturated C.sub.6-22 alkyl radical,
• A is either--NH-- or --O--,
• X.sup.- is an anion of an inorganic or organic acid,
• k, l and m independently of one another are integers of 1 to 6,
• y is 0, 1, 2 or 3 where A=--NH-- and 1, 2, 3 or 4 where A=--O-- and
• n is an integer of 0 to 6.
