COMPOSITIONS AND FILMS COMPRISED OF AVIAN FEATHER KERATIN.

摘要

A composition suitable for making films, wherein the composition contains keratin obtained from avian feathers and at least one OH containing plasticizer Protein-based films containing at least one protein and at least one OH containing plasticizer, wherein the protein is a protein whose PE value is 2.5 where PE=(S+T+Y)/C where PE is plasticizer efficiency and where S, T, Y, and C are the amino acids serine, threonine, tyrosine, and cysteine, respectively, in the protein. Preferably the protein is keratin obtained from avian feathers.
