The present invention is directed to a concentrate for use as chain lubricant comprising: a) at least one ester selected from the group consisting of monoesters and diesters represented by the aa) general formula (1) R<1>-COOR<2>; ab) general formula (2) R<1>OOC-R<3>-COOR<2> ; ac) general formula (3) R<1>-COOR<3>OOC-R<2>, and mixtures thereof, whereby R<1> is a C1-C22-alkyl group or a C8-C22-alkenyl group, R<2> is a C1-C22-alkyl group or a C8-C22-alkenyl group, R<1> and R<2> being the same or a different, R<3> is a C2-C16-alkylene group, and the sum of carbon atoms present in R<1>, R<2> and R<3> of each monoester or diester being at least 10, and b) at least one anionic surfactant, and a lubricant solution comprising the concentrate and a suitable diluent. |
