| abstract |
The invention relates to cyclodextrin derivatives of formula (I): n nin which: n R 1 ═—NH-E-AA-(L 1 ) p (L 2 ) q n nwhere E=a linear or branched Cl-Cl 5 hydrocarbon-based group with, optionally, one or more hetero atoms; AA=the residue of an amino acid; L 1 and L 2 =a C 6 -C 24 hydrocarbon-based group with, optionally, one or more hetero atoms; p and q=0 or 1, at least one being ≠0; n R 2 ═H, —CH 3 , isopropyl, hydroxypropyl, sulphobutyl ether; R 3 ═H or R 2 , except when R 2 =hydroxypropyl; all the R 4 ═—OH or R 2 , except when R 2 =hydroxypropyl, or at least one of the R 4 ═R 1 ; 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. |
