When submerged, the hydrogen bonds holding the cellulose fibers together are broken by water molecules. The paper loses its structural integrity and turns into a sludge or pulp.
Even the most “flushable” toilet paper won’t break down properly if conditions are poor. Key factors include:
Most standard toilet paper is designed to dissolve in water, which is critical for avoiding clogs in plumbing and septic systems. Frank's Mr. Plumber does toilet paper dissolve
Unlike facial tissues, paper towels, or napkins (which are made with long, strong fibers and chemical binders to resist moisture), toilet paper is engineered for rapid disintegration. Manufacturers use:
You can see for yourself how well your brand dissolves: When submerged, the hydrogen bonds holding the cellulose
Where your waste goes determines how worried you should be about dissolving paper.
Once toilet paper enters the sewer system, it undergoes further breakdown. In a properly functioning sewer system: Key factors include: Most standard toilet paper is
| Product | Does it Dissolve? | Why? | | :--- | :--- | :--- | | | Yes | Made with short fibers and designed to break apart when agitated in water. | | Paper Towels | No | Designed for strength when wet. They have long fibers and high sizing to prevent disintegration. | | Facial Tissue | No | Treated with chemical binders to stay strong when you blow your nose. They create "slime" that clogs pipes. | | "Flushable" Wipes | No (mostly) | Made from synthetic non-woven fabrics. They eventually break down, but take months or years, unlike toilet paper which takes minutes. |
