Title: Digestion of keratin

Abstract: The present invention relates to the chemical digestion of keratin, such as avian feathers and wool. The digestion product is made by heating the feathers or wool with a solvent selected from glycols, alkanolamines, polyamines, and combinations thereof.

The digestion products provide a sustainable alternative to petrochemical based intermediates.
