The present invention relates to absorbent articles such as diapers, incontinence protectors, sanitary napkins, wound dressings and similar articles which are applied in contact with skin, and concerns methods which make it possible to use an article for an extended period of time without the appearance of unwanted side-effects such as, for instance, growth of undesirable micro-organisms. The absorbent body in the absorbent article comprises a pH-controlling substance in the form of a partially neutralised super-absorbent material in such a manner that the pH in the absorbent article after wetting is in the interval 3.5 - 4.9. Growth of undesirable strains of micro-organisms is prevented and unwanted side-effects resulting from use of the article are reduced.
L'invention concerne des articles absorbants, tels que des couches, des protections d'incontinence, des serviettes hygiéniques, des pansements et articles similaires, qui sont mis en contact avec la peau. L'invention concerne également des procédés permettant d'utiliser un article plus longtemps sans que pour autant n'apparaissent des effets secondaires indésirables, tels que la croissance de micro-organismes indésirables. Le corps absorbant de l'article absorbant comporte une substance de contrôle du pH se présentant sous la forme d'une matière super-absorbante partiellement neutralisée de telle manière que le pH de l'article absorbant se situe, après mouillage, entre 3,5 et 4,9. Ainsi la croissance de souches de micro-organismes indésirables est enrayée et les effets secondaires indésirables liés à l'utilisation de l'article sont réduits.
