摘要： The present invention provides an absorbent article that suppresses acetaldehyde odor. This absorbent article is obtained by layering at least a liquid-permeable sheet, an absorbent body containing a water-absorbing resin, and a liquid-impermeable sheet in this order, wherein at least some of a hydrazide compound is present on the liquid-permeable sheet side with respect to the absorbent body.

摘要： Provided is a water-absorbing resin with which the enzyme activity of a urease that generates ammonia from urea can be inhibited and a pH increase on the surface of an absorbent article, which causes skin rashes or the like, can be suppressed. This water-absorbing resin has an oxidation-reduction potential of a swollen gel of at least 260 mV, as measured by the following oxidation-reduction potential measuring method. (Oxidation-reduction potential measuring method) 60 mL of ion exchange water having an oxidation-reduction potential of 390±10 mV is added to a beaker. The oxidation-reduction potential of the ion exchange water is measured after an electrode of a pH meter is inserted into the ion exchange water and left alone for 15 minutes. Next, 2.0 g of a water-absorbing resin is added to the ion exchange water that is being stirred at 400 rpm, and the resultant is stirred to obtain a swollen gel. An electrode of a pH meter is inserted into the swollen gel and left alone for 15 minutes, and then the oxidation-reduction potential thereof is measured.
