• fibres
  • EP0806199A2 ] - Colourant for keratin fibres, based on vegetable dyes, is in the form of a colour suspension containing (a) pulverised vegetable dye(s), (b) oil(s) and (c) direct dye(s). (epo.org)
  • proteins
  • Keratin ( / ˈ k ɛr ə t ɪ n / ) is one of a family of fibrous structural proteins . (hitchhikersgui.de)
  • By analysis of the primary structures of these keratins and other intermediate filament proteins, Hanukoglu and Fuchs suggested a model that keratins and intermediate filament proteins contain a central ~310 residue domain with four segments in α-helical conformation that are separated by three short linker segments predicted to be in beta-turn conformation.

  • Antisera were prepared to the unfractionated keratin proteins from the follicle and the specificity of these antisera examined by immunodiffusion and immunoelectrophoresis. (biologists.org)
  • composition
  • A composition for the oxidation dyeing of keratin fibers, such as human keratin fibers and further such as the hair, comprising, in a medium that is suitable for dyeing and that is free of glycerol and of cationic synthetic thickening polymer comprising at least one fatty chain, at least one oxidation. (google.com.au)
  • A composition for the oxidation dyeing of keratin fibers, such as human keratin fibers and further such as the hair, comprising, in a medium that is suitable for dyeing and that is free of glycerol and of cationic synthetic thickening polymer comprising at least one fatty chain, at least one oxidation dye, at least one fatty alcohol chosen from mono- and polyglycerolated fatty alcohols, and at least one particular polyol. (google.com.au)
  • A ready-to-use composition for the oxidation dyeing of keratin fibers, and, in particular, human keratin fibers such as the hair, including at least one oxidation base, at least one ammonia-generating 2-electron oxidoreductase type enzyme, and at least one donor for the enzyme, as well as a dyeing process.

  • form
  • Keratin monomers assemble into bundles to form intermediate filaments , which are tough and form strong unmineralized epidermal appendages found in reptiles , birds , amphibians , and mammals . (hitchhikersgui.de)
  • Fibrous keratin molecules supercoil to form a very stable, left-handed superhelical motif to multimerise, forming filaments consisting of multiple copies of the keratin monomer . (hitchhikersgui.de)
