Abstract
There is provided a BM containment system for personal care products having an expandable material which expands upon contact with fluids to form a compartment in which BM may be contained. The system may optionally have a dewatering layer on the side away from a wearer of the personal care product. The system may also be in liquid isolation from other personal care product components which are located on the side away from a wearer in order to keep the BM containment system from expanding from exposure to urine. Liquid isolation may be provided by a film between the other system components and the traditional personal care product components.
