See full text

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 resulting digested keratin product is a keratin-derived polyol useful for making polymeric materials such as polyurethanes. The digestion products provide a sustainable alternative to petrochemical based intermediates.
