Abstract

An absorbent article, such as a diaper, panty diaper, sanitary napkin or incontinence device includes a liquid-permeable topsheet, a backsheet and an absorbent core enclosed between the liquid-permeable topsheet and the backsheet. The absorbent core includes acidic fluff pulp having a pH of 5.5 or less and an organic zinc salt, in particular zinc ricinoleate. The combination of organic zinc salt and acidic fluff pulp exerts a synergetic effect in the suppression of ammonia.
