When chicken feathers are treated in aqueous NaOH at high pH and elevated temperature, they completely solubility in water.On their dissolution, added dopant/modifiers react with exposed functional groups such as carboxylic (−COOH), thiol (−SH), amino(−NH2) and hydroxyl (−OH) group changing chemical behavior of interaction forces. Thereafter, pH adjustment can evolve rich precipitates of completely modified form of regenerated keratin at isoelectric point of reaction mixture.
