Abstract

See full text

The present invention relates to a method for preparing a cyclodextrin polymer and/or a hydrophilic polymer emulsion having cyclodextrins as well as lipophilic compounds, the emulsions having a remarkable stability. In particular, the method includes: (i) adding a lipophilic compound into an aqueous solution of a cyclodextrin unit polymer or hydrophilic polymer having cyclodextrins; (ii) forming an emulsion from the mixture resulting from step (i). The invention also relates to the resulting emulsions, i.e. stabilized emulsions by a non-covalent and non-crystalline inclusion complex consisting of (i) a cyclodextrin unit polymer or a hydrophilic polymer having cyclodextrins and (ii) a lipophilic compound. The invention also relates to the use of said emulsions in the cosmetic, pharmaceutical and/or agri-food fields.
