Article Correctness Is Author's Responsibility: Triclosan Accumulates in Toothbrushes, Potentially Prolonging Users’ Exposure

In September, a ban on triclosan in over-the-counter antiseptic soaps, gels and wipes went into effect in the U.S. But the antibacterial ingredient is still allowed in toothpastes for its reported ability to reduce gum inflammation, plaque and cavities. Now a study in ACS' Environmental Science & Technology has found that triclosan accumulates in toothbrush bristles and elastomer parts, and is readily released when users switch toothpastes, potentially prolonging users' exposure to the compound.
