| Résumé : |
With the intention of utilizing solubilized keratins as a biomaterial, the solubilities of cattle and pig hair keratins were studied. Samples of hair were collected from steer hides and pig skins with razors and treated with sodium thioglycolate or performic acid. The effects of concentration of the reducing or oxidizing agent, incubation temperature and time on the solubility of hair keratins were examined.
The results obtained were compared with those of human hair reported previously. About 60% of steer hair keratins and 50% of pig hair keratins were dissolved in 0.1M sodium thioglycolate at pH 11 and 35°C after 24 hr incubation. When oxidized with 90% formic acid - 3% hydrogen peroxide, the solubilities of steer hair and pig hair keratins were about 75% and 50% after 6 hr incubation, respectively. When the residues from hair oxidized with performic acid were incubated 0.2M sodium carbonate, additional keratins were dissolved. The total amount was about 95% of steer hair and 90% of pig hair after 24 hr incubation.
