When these disposable diapers and sanitary pads absorb excrement from the body, they each generate an unpleasant odor. In the case of urine, urea, amino rR, etc. in the urine are decomposed by microorganisms and converted into malodor-producing substances such as ammonia. Also,
Physiological odor is also thought to be caused by microbial decomposition of excreted amino acids and the like.
