Abstract
A thermoplastic porous water-permeable layer material has at least one odor-reducing surface which is wettable to aqueous liquids and capable of controlling a wide variety of malodors. The thermoplastic water-permeable layer material is treated with a surfactant-modified cyclodextrin prepared by mixing or chemically reacting a cyclodextrin-based odor absorbing material with a surfactant-producing compound. The layer material thus treated can be used in a wide variety of personal care and medical absorbent products, as well as other applications.
