Abstract
Absorbent articles such as diapers, incontinence protectors, sanitary napkins, wound dressings and similar articles which are applied in contact with skin, and 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 microorganisms. The absorbent body in the absorbent article comprises a pH-controlling substance in the form of a partially neutralized 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 microorganisms is prevented and unwanted side-effects resulting from use of the article are reduced.
