ABSTRACT:
A multifunctional material is provided for use in personal care products. The multifunctional material has a permeability between 100 and 10000 Darcys and a capillary tension between about 2 and 15 cm. Structures containing this multifunctional material can have a runoff rate of less than 25 ml per 100 ml insult, over its life. The multifunctional material should have between about 30 and 75 weight percent of a slow rate superabsorbent, between 25 and 70 weight percent of pulp and from a positive amount up to about 10 percent of a binder component. The material preferably has a density between about 0.05 and 0.5 g/cc. The material has a liquid pass through function which desorbs a surge material across time frames consistent with user conditions and releases the liquid for distribution to remote storage locations. The material, when combined with the intake and distribution materials, defines a composite structure for use in personal care products.
