A recent study by University of California at Davis School of Veterinary Medicine researchers claims that injected doses of 12.5 milligrams per kilogram body weight (mg/kg-bw) or more of triclosan impaired heart contractions in mice, while an injection of 40 mg/kg-bw caused an 18 percent decrease in grip strength.

In addition, fathead minnows swimming in water with 0.52 micromolars of triclosan had difficulty swimming. Triclosan is a high-production-volume chemical used in soap and other personal-care products as well as conveyor belts, fire hoses, dye bath vats, ice-making equipment, adhesives, fabrics, vinyl, plastics, floor wax, textiles, caulks, sealants, rubber, and carpeting.
