'Safe to flush' wipes MUST be biodegradable

Tests can be made by placing a wet wipe in a plastic bottle of water ... and waiting to see the result. One of Britains's largest supermarket's own brand wipes do NOT biodegrade. Another's start to biodegrade after a very long period of time. One of the smaller supermarket's wipes begin to biodegrade within hours. This inconsistency results in millions of wipes ending up up in our oceans and on our beaches.
