Flushaway's sanitary towels and panty liners are flushable and offer the same characteristics and functionality as other brands. When the sanitary towels and panty liners are placed in the toilet bowl, the 'plastic-like' moisture barrier starts to break down immediately upon water contact. All materials used are environmentally friendly and biodegradable except for the positioning adhesive, which is inert. The product is safe for septic tanks and Porta Loo's. Flushaway has passed the international standards test for products that wish to be marketed as "biodegradable". The test measures the time taken for sanitary towels to degrade - the ASTM D5988-03 method. According to this standard, a product must degrade by 70% in six months. The Flushaway sample degraded by over 71% in just 70 days (about 2 months). This is well within the required parameter for the claim of "Biodegradable".
