Abstract: An anal pad for preventing soiling of underwear due to undesired anal discharge. The anal pad includes a thin outer shell enclosing a semi-rigid shell. The semi-rigid shell may be a layer on one interior surface of the outer shell and it may also partially cover the opposite interior surface of the outer shell. An absorbing layer is located within the outer shell and the semi-rigid layer. The absorbing layer contains glycerin which absorbs hydrogen sulfide gas and the combination of the absorbing layer and the semi-rigid shell acts as a sound muffling camera so as to decrease the noise due to flatus. The absorbing layer is made of a light porous materials, the semi-rigid layer is made of compressed paper and the outer shell is made of a thin sheet of lignin paper. A layer of glue is provided on the outer surface of the anal pad for attaching it to a user's underwear.
