Abstract
The present invention relates to nanoparticles for encapsulating compounds, the preparation and uses thereof, said nanoparticles being based on half (C1-C4) alkyl esters of poly (methyl vinyl ether-co-maleic anhydride) (PVM/MA) copolymers. Said nanoparticles can encapsulate or incorporate a product of interest for use in the agricultural, cosmetic, food or pharmaceutical fields.
Claims22
A nanoparticle selected from the group consisting of:
- a) a matrix nanosphere, wherein said matrix nanosphere comprises a matrix, said matrix comprising a half (C1-C4) alkyl ester of a poly (methyl vinyl ether-co-maleic anhydride) (PVM/MA) copolymer;
- and
- b) a core-shell vesicular nanocapsule, wherein said core-shell vesicular nanocapsule comprises a core and a shell, said shell comprising a half (C1-C4) alkyl ester of a PVM/MA copolymer,
- wherein the nanoparticle has long-term stability in aqueous media.
