Zusammenfassung:Hydrolyzed keratin-containing materials, methods of preparing such materials, and compositions that include such materials are described. The method can include combining a keratin-containing material with an acid, processing the keratin-containing material by steam hydrolysis, and reducing a particle size of the keratin-containing material. The hydrolyzed keratin-containing material can include 1.0% by weight or less of lanthionine, relative to the total weight of the hydrolyzed keratin-containing material. Se describen materiales que contienen queratina hidrolizada, métodos para preparar dichos materiales y composiciones que incluyen dichos materiales. El método puede incluir combinar un material que contiene queratina con un ácido, procesar el material que contiene queratina mediante hidrólisis con vapor y reducir el tamaño de partícula del material que contiene queratina. El material que contiene queratina hidrolizada puede incluir 1.0% en peso o menos de lantionina, con respecto al peso total del material que contiene queratina hidrolizada.
