Method of preparing solutions from keratinous protein materials based on hydrolysis of the keratinous protein material using a strong organic base, or a mixture of organic bases or their solutions provided that the resulting product obtained by the said alkaline conditions is water soluble. At least one amine, the boiling point of which at normal pressure is below 200 °C, is used as strong organic base. The at least one amine can be selected from the group comprising cyclohexylamine, isopropylamine, diisopropylamine, butylamine and diethylamine. |
