  • Patent number: 11913164
    Abstract: The disclosure provides a composition comprising a modified cellulosic surface having aliphatic fatty acid molecules and amine-silica particles that are covalently bonded to cellulose fibers of the cellulosic surface. Also disclosed is a composition comprising a modified cellulosic surface including low surface energy molecules and amine functionalized nanotubes decorated with silica nanoparticles that are covalently bonded to cellulose fibers of the cellulosic surface. Also disclosed is a process for increasing hydrophobicity of a cellulosic surface. Also disclosed is a process for increasing hydrophobicity and surface roughness of a cellulosic surface. Also disclosed are products comprising the compositions and modified cellulosic surfaces of the present invention.

  • Publication number: 20230000748
    Abstract: Disclosed is a method of crosslinking hair or other keratin fibers by (i) providing a crosslinking agent comprising an oxidized sugar having at least two aldehyde groups; and (ii) infiltrating a plurality of non-crosslinked hair or other keratin fibers with the crosslinking agent under conditions effective to cause protein molecules contained in the non-crosslinked hair or other keratin fibers to become crosslinked, thereby yielding a population of crosslinked hair or other keratin fibers. The protein molecules include amine groups that react with the aldehyde groups of the oxidized sugar to yield the crosslinked hair or other keratin fibers. Also disclosed are formulations for crosslinking hair or other keratin fibers and methods of using the formulations to treat human hair to maintain a desired three dimensional structure. This formulation includes a crosslinking agent having a plurality of oxidized sugars having at least two aldehyde groups or mixture thereof.

  • Patent number: 11530300
    Abstract: Disclosed is a method of crosslinking protein fibers, including wool fibers, by (i) providing a crosslinking agent including an oxidized sugar mixture having a plurality of different oxidized sugars of different molecular lengths and having at least two aldehyde groups (e.g., oxidized soy flour sugars); and (ii) infiltrating a plurality of non-crosslinked protein fibers with the crosslinking agent under conditions effective to cause protein molecules contained in the non-crosslinked protein fibers to become crosslinked. This method yields a population of crosslinked protein fibers, where the protein molecules of the non-crosslinked protein fibers include amine groups that react with the aldehyde groups of the oxidized sugars to achieve the crosslinking of the protein molecules to yield the crosslinked protein fibers.
