Abstract
(EN)
The present invention also provides lignin nanoparticles comprising a hydrophobic active agent. The present invention provides a process for the production of lignin nanoparticles comprising a hydrophobic active agent, the process comprising the following steps: (i) dissolving modified lignin and a hydrophobic active agent in an organic solvent having low solubility in water; (ii) combining the solution with water and a surfactant to form a pre-emulsion; (iii) forming an emulsion from the pre-emulsion: and (iv) crosslinking the modified lignin to form lignin nanoparticles comprising the hydrophobic active agent, wherein the modified lignin is lignin which is chemically modified to comprise at least two functional groups suitable for polymerization and /or crosslinking.

La présente invention concerne des nanoparticules de lignine comprenant un agent actif hydrophobe. La présente invention concerne un procédé pour la production de nanoparticules de lignine comprenant un agent actif hydrophobe, le procédé comprenant les étapes suivantes : (i) dissoudre la lignine modifiée et un agent actif hydrophobe dans un solvant organique ayant une faible solubilité dans l'eau ; (ii) combiner la solution avec de l'eau et un tensioactif pour former une pré-émulsion ; (iii) former une émulsion à partir de la pré-émulsion ; et (iv) réticuler la lignine modifiée pour former des nanoparticules de lignine comprenant l'agent actif hydrophobe, la lignine modifiée étant la lignine qui est modifiée chimiquement pour comporter au moins deux groupes fonctionnels appropriés pour la polymérisation et/ou la réticulation.
