Abstract
An interlabial absorbent article configured for disposition primarily within the vestibule of a female wearer includes a generally liquid permeable cover sheet, a generally liquid impermeable back sheet, and an absorbent material disposed between the cover sheet and the back sheet. The back sheet has a water vapor transmission rate that is at least about 20% of a water vapor transmission rate of the cover sheet. The cover sheet and said back sheet may have a contact angle mismatch of less than about 25%. The absorbent material may have a density greater than water. Upon being flushed, the article has an initial neutral buoyancy and subsequently sinks within about 7 days from being flushed.
