Possible Causes: Some grades of toilet paper contain lanolins, dyes, and other compounds that provide certain benefits to consumers (i.e. softness, fragrance, strength) yet inhibit the proper breakdown of the paper in flowing water.
There are also many brands of paper that use raw materials of different types with different breakdown characteristics. For example, most paper manufactured by Fort Howard uses White Pine to create the paper pulp. Other companies may use whatever material is prevalent in their region, i.e. Southern Pine in the south.
