Abstract
The present invention relates to articles, preferably disposable absorbent articles like sanitary napkins and pantiliners, which comprise a cationic polysaccharide, preferably chitosan material, and silica. Such disposable absorbent articles deliver improved odor control performance (synergistic odor reduction) and improved fluid handling properties/absorption performance. In one embodiment of the present invention, articles are provided which comprise crosslinked silica-cationic polysaccharides. These articles deliver not only improved odor control and fluid handling properties when in use but are able to maintain these properties even upon prolonged wearing time, typically upon ageing of the bodily fluid in the articles and/or upon subsequent fluid discharge in the articles.
