All this info was gotten off their Wikipedia page:
Sensodyne is a brand of toothpaste that was first sold by Block Drug, a Brooklyn, New York-based company established in 1907 by pharmacist Alexander Block.[1]
In 2000, Block Drug was purchased by Smith Kline Beecham P.L.C.,[11] which became GlaxoSmithKline (NYSE:GSK).[12]
Sensodyne became a part of Haleon, a British multinational consumer healthcare corporation, in July 2022, following the establishment of Haleon as a separate entity through a corporate spin-off from GSK.[14]
