Abstract
This article shows the results of solubility tests of keratin not only in basic media, close to the isoelec-tric point, but also in acidic media in the presence of different salts such as sodium and potassium halides, as well as several alkaline chlorides. The salt`s effect on the solubility of keratin or keratoses is described in terms of the law of matching water affinity, based on the distinct tendency of ions towards hydration. The application of this principle is focused on explaining the interaction`s competitiveness between inorganic salts` ions and ionized groups of keratin amino acids.
