ABSTRACT:
The invention relates to cyclodextrin derivatives of formula (I):in which:R1=—NH-E-AA-(L1)p(L2)qwhere E=a linear or branched C1-C15hydrocarbon-based group with, optionally, one or more hetero atoms; AA=the residue of an amino acid; L1and L2=a C6-C24hydrocarbon-based group with, optionally, one or more hetero atoms; p and q=0 or 1, at least one being ≠0;R2=H, —CH3, isopropyl, hydroxypropyl, sulphobutyl ether;R3=H or R2, except when R2=hydroxypropyl;all the R4=—OH or R2, except when R2=hydroxypropyl, or at least one of the R4=R1;n=5, 6 or 7.The invention also relates to a process for preparing them, and to inclusion complexes and organized surfactant systems comprising them.
