Vesicles comprising an amphiphilic di-block copolymer and a hydrophobic compound

摘要

The invention relates to new vesicles structures, and their use for delivering actives. The vesicles according to the invention are obtained from di-block copolymers. The vesicles comprise an external shell of a di-block copolymer comprising a hydrophilic block and a hydrophobic block, and at least one internal shell of the same or another di-block copolymer comprising a hydrophilic block and a hydrophobic block, the hydrophobic block of the external shell facing the hydrophobic block of the internal shell(s), and further comprise a hydrophobic compound between the shells.
