摘要: Proteinaceous cellulose microparticles are provided. These microparticles comprise cellulose nanocrystals and one or more peptide, one or more protein, or a mixture thereof, wherein the nanocrystals and the peptide(s) and/or protein(s) are aggregated together to form the microparticles. In embodiments, the microparticles comprise silk fibroin and advantageously are hydrophobic and lipophilic. There are also provided cosmetic preparations comprising these microparticles. In advantageous embodiments, these cosmetic preparations comprise a water-in-oil emulsion or a lipophilic medium. Finally, there are also provided methods of producing the microparticles.

摘要: Porous cellulose microparticles and their use in, inter alias, cosmetic and pharmaceutic preparations are provided. These microparticles comprise cellulose I nanocrystals aggregated together, thus forming the microparticles, and arranged around cavities in the microparticles, thus defining pores in the microparticles. A method of for producing these microparticles is also provided. It involves mixing a suspension of cellulose I nanocrystals with an emulsion of a porogen to produce a mixture comprising a continuous liquid phase in which droplets of the porogen are dispersed and in which the nanocrystals of cellulose I are suspended; spray-drying the mixture to produce microparticles; and if the porogen has not sufficiently evaporated during spray-drying to form pores in the microparticles, evaporating the porogen or leaching the porogen out of the microparticles to form pores in the microparticles.

摘要: A microparticle comprised of dried cellulose nanocrystals agglomerated together and forming said microparticle is provided, wherein the CNCs are surfaced-reduced carboxylated CNCs, and wherein the microparticle is nanoredispersible into its constituting cellulose nanocrystals in both aqueous and non-aqueous solvents. A method for producing nanoredispersible microparticles comprised of dried CNCs is also provided.
