THICKENING AGENT

摘要

The invention relates to novel thickening agents of formula (I), R<1>O(CH2CH2O)n1CONH-X-NHCOO(CH2CH2O)mCONH-Y-NH-OC(OCH2CH2)N2OR<2> (I), wherein R<1> and R<2> 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-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> 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.
