The invention relates to novel thickening agents of formula (I), R1O(CH2CH2O)n1CONH-X-NHCOO(CH2CH2O) mCONH-Y-NH-OC(OCH2CH2) n2OR2 (I), wherein R1 and R2 independently represent linear or branched, saturated or unsaturated alkyl radicals having 6 to 22 carbon atoms and 0 and/or between 1 and 3 double bonds, the sum of n1 and n2 is equal to 0 or a number between 1 and 100, and m represents a number between 4 and 500, -[(CH2) z1-CR3R4] a1-[PH] x-[CR5R8-(CH2) z2] a2- (II) wherein R3, R4, R5, and R6 independently represent hydrogen or alkyl radicals having between 1 and 4 carbon atoms, Ph represents an optionally alkyl-substituted phenyl radical and x, a1, a2, z1 and z2 independently represent 0 or 1. |
