Thickeners corresponding to the general formula (I): R<1>O(CH2CH2O)n1CONH-X-NHCOO(CH2CH2O)mCONH-Y-NHOC(OCH2CH2)n2OR<2> (I) wherein R<1 >and R<2 >each independently represents an alkyl group having from 6 to 22 carbon atoms and up to 3 carbon-carbon double bonds; n1 and n2 each independently represent numbers, the combined value of which is from 0 to 100; m represents a number having a value of from 4 to 500; and X and Y each independently represents an alkylene group corresponding to the general formula (II): -[(CH2)z1-CR<3>R<4>]a1-[Ph]x-[CR<5>R<6>-(CH2)z2]a2- (II) wherein R<3>, R<4>, R<5 >and R<6 >each independently represents a hydrogen or an alkyl group having from 1 to 4 carbon atoms, Ph represents a phenyl group or an alkyl-substituted phenyl group, and x, a1, a2, z1, and z2 each independently represents a number having a value of 0 or 1; are described along with processes for producing the same and methods of using the same.
