Dettol is a brand line of products used for disinfection and as an antiseptic. This brand was created with the introduction of Dettol antiseptic liquid in 1933 by the British-Dutch concern Reckitt Benckiser. The Dettol brand line has been expanded over the years and now includes products containing many different active ingredients. The name Dettol was invented by British scientist Lloyd Roake.[citation needed]

Dettol was a progressive idea of how germs spread at that time, since handwashing practices were still developing. Notably, it would help reduce infection rates of puerperal sepsis when delivering babies.
