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 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.
