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.

Un material permeable al agua poroso termoplástico de la capa tiene por lo menos una superficie olor-reductora que sea mojable a los líquidos acuosos y capaz de controlar una variedad amplia de malodors. El material permeable al agua termoplástico de la capa se trata con un cyclodextrin surfactant-modificado preparado mezclando o químicamente reaccionando un material absorbente cyclodextrin-basado del olor con un compuesto surfactant-que produce. El material de la capa tratado así se puede utilizar en una variedad amplia de cuidado personal y de productos absorbentes médicos, así como otros usos.
