A fibrous material, which can be an absorbent material, includes a plurality of natural fibers treated with a carboxylic acid-based odor control agent, which are able to withstand insults with an aqueous liquid without dissolving the odor control agent. The acid-based odor control agent is bound to the natural fibers by an organosilicone polymer binder. The binder is water-insoluble, and can form a highly gas permeable coating. The binder is also highly porous, so as to expose the odor control agent to ammonia and other odoriferous gases which it is intended to control.
