Bio-Soft liners are flushable diaper liners that make clean-up a breeze. There's no need to sacrifice convenience when you choose cloth diapers - there will be no rinsing of poopy cloth diapers in the toilet. Bio-Soft liners contain the solid waste: you simply discard the soiled liner in the toilet and flush away the mess. They are non-irritating and ever so soft and comfortable against baby's sensitive skin. Our Bio-Soft liners are made of a non woven material with no binder, and will biodegrade very quickly (within 8 days in a sewage treatment system or 20 days in a septic tank). They are 100% viscose rayon, a cellulosic fibre derived from natural sources, and are made to our specifications in England.
