Abstract:
A process for producing a protein hydrolysate derived from keratin containing material with an oxidative bleaching agent at an acidic pH and mixing the keratin hydrolysate as an additive to the wet-end of a papermaking process. The process achieves a paper with a lower porosity and greater breaking length.
