Abstract: Microparticles and nanoparticles of hydrophobized polysaccharide and an alpha-cyclodextrin, obtained by self-association in an aqueous medium, the hydrophobized polysaccharide being obtained by grafting of alkyl chains derived from fatty acids, by an acylation reaction. These microparticles and nanoparticles constitute systems used for encapsulating substances of interest, in particular in the pharmaceutical field, and vectorization thereof for therapeutic purposes.

Abstract: A composition including hydrophobized chitosan can be used as an antiparasitic and/or antifungal agent or in the treatment of parasitic and/or fungal infections. The composition may include an antifungal agent and hydrophobized chitosan. The antifungal agent can be in association with the hydrophobized chitosan, with the latter being more preferably in the particle form, or the antifungal agent can be encapsulated in particles including the hydrophobized chitosan. The use of the composition as an antifungal agent or in the treatment of fungal infections, and a method for manufacturing the composition are also described.

Abstract: Microparticles and nanoparticles of hydrophobized proteins and an alpha-cyclodextrin, obtained by auto-association in an aqueous medium, the hydrophobized protein being obtained by grafting of alkyl chains coming from fatty acids, by an acylation reaction. These microparticles and nanoparticles constitute systems used for encapsulation of active substances of interest, in particular in the pharmaceutical field, and the vectorization thereof for therapeutic purposes.

Abstract: In the field of cosmetics or pharmaceuticals, and particularly to the dermatological field, disclosed are particles containing hyaluronic acid modified by hydrophobic groups and the use thereof as an agent for stimulating the epidermis and/or dermis. In particular, the assemblies are useful on the one hand, as a moisturising and/or plumping and/or volumising agent. On the other hand, the particles containing hydrophobised hyaluronic acid are useful for reactivating endogenous hyaluronic acid expression thereby making it possible to reduce and/or prevent skin imperfections such as filling in wrinkles and lines.
