Abstract
Absorbent articles containing both pH control agents and substantially water-insoluble, highly neutralized hydrogel material as a fluid-absorbing polymer are disclosed. By placing pH control agents and hydrogel in distinct discrete zones within the article, absorbent products such as diapers can be realized which are highly effective for absorbing discharged body fluids and which also serve to prevent or reduce diaper rash.
