Description

<p>Deodorant face masks generally make use of activated carbon. Activated carbon removes odors by physical adsorption, but adsorptioll of malodorous components in the extremely short time during which they pass through the mask is difficult to achieve, so these deodorant masks have fallen short of requisite deodorizing performance. A newly developed deodorant face mask of the nonwoven fabric type employs a high performance inorganic deodorizing agent that removes odors in an extremely short time by use of both physical adsorption and chemical reaction. After consideration of methods of evaluating the requisite deodorizing performance, the mask was optimized by assigning the deodorant processing conditions of a nonwoven fabric mask to an L18 orthogonal array with the amount of malodorous gas supplied as the input and the amount captured as the output, and introducing noise factors based on contemplated conditions of use. It was confirmed that in deodorizing performance, the newly developed deodorant face mask was superior to activated carbon masks.</p>
