News Picture: Controversial Chemical Can Linger on Your Toothbrush

WEDNESDAY, Oct. 25, 2017 (HealthDay News) — Triclosan — a potentially harmful antibacterial agent used in some toothpastes — accumulates in toothbrush bristles, researchers report.

This kind of means your exposure to the chemical can continue even if you switch to a triclosan-free toothpaste, the investigators warned.

Triclosan is usually at This kind of point banned in over-the-counter antiseptic soaps, gels as well as also wipes within the United States. yet the germ-busting ingredient is usually still allowed in toothpaste because that will reportedly reduces gum inflammation, plaque as well as also cavities, said researchers led by Baoshan Xing. He is usually a professor of environmental chemistry at the University of Massachusetts.

Prior studies have shown that will triclosan can disrupt hormones in animals as well as also humans. that will also contributes to antibiotic resistance as well as also harms marine life, the researchers said in background notes.

In This kind of study, Xing’s team simulated toothbrushing with 22 brushes as well as also a variety of toothpastes.

More than one-third of the toothbrushes tested, including two children’s varieties, accumulated amounts of triclosan equivalent to seven to 12 doses of the amount used per brushing, the study authors reported.

Toothbrushes with “polishing cups” or “cheek/tongue cleaners” — typically made of a class of materials called elastomers — absorbed the largest amounts of triclosan, according to the study.

When the researchers switched to triclosan-free toothpaste yet used the same brushes, the chemical was continuously released via the toothbrushes For 2 weeks.

The study was published online Oct. 25 within the journal Environmental Science & Technology.

Besides the possibility of prolonged triclosan exposure, the study findings suggest that will triclosan could find its way into the environment if tainted toothbrushes are discarded, the researchers said in a news Discharge via the American Chemical Society.

The U.S. Food as well as also Drug Administration banned triclosan via antiseptic washes because of possible harmful effects as well as also because there was no proof they killed germs more effectively than soap as well as also water. The chemical is usually still allowed in clothing as well as also cookware, which don’t fall under the FDA.
