Nickelammonium hydroxide combines not only with wool, but also with feather keratin, hide powder, egg albumen, casein, and formalised casein. Some proteins dissolve yielding red solutions, from which metal‐containing complexes may be obtained by addition of ethyl alcohol. The nickel content of these complexes is high. Polyglycine is soluble in concentrated solutions of nickelammonium hydroxide.
