The present invention relates to articles, preferably disposable absorbent articles like sanitary napkins and pantiliners, which comprise a cationic polysaccharide, typically chitin-based material and/or chitosan material, and an acidic pH buffering means. Such disposable absorbent articles deliver improved odor control performance even upon prolonged wearing time of the articles.
