The invention concerns a composition comprising an aqueous dispersion of particles (p) of hydrodynamic mean diameter ranging between 50 and 5000 nm, said particles containing, in combination: (A) polymers based on cyclodextrin units, including on the average at least 4 cyclodextrin units inside their structure; and (B) polysaccharide macromolecules including groups G capable of forming inclusion complexes with the cyclodextrins present in the structure of said polymers (A), the average number of groups G per polysaccharide molecule being not less than 3, said compounds (A) and (B) being water-soluble in isolated state. The invention also concerns the method for preparing said compositions, and their use for encapsulating compounds such as active principles. |
