After years of research FlushawayTM has perfected and patented the technology for replacing the plastic films used in napkins and liners, with its own B-9b film. This revolutionary film, enhanced by nanotechnology, has all the properties of regular plastic for the purpose of containing menstrual fluids, yet it begins to break down as soon as it comes in contact with the water in the toilet bowl. The swirling action and agitation in the bowl helps break down the napkin so that it is totally flushable. The rest of the material used in the napkins breaks apart while flowing through the pipes and biodegrades in 71 days; 66% faster than the ASTM D5988-03 International standard requires.
