Sorry, I should have posted something about it.

Benzalkonium chloride/lidocaine (trade name Bactine among others) is an antiseptic, first-aid treatment distributed by Wellspring Pharmaceutical Corporation. Bactine was developed in 1947 and first marketed in 1950 by Miles Laboratories. It is a topically applied first aid liquid with active ingredients benzalkonium chloride (an antiseptic) and lidocaine (a topical anaesthetic). As an antiseptic, Bactine can help to prevent infections, while the topical anesthetic in Bactine serves to numb the surface of a body part and temporarily relieve pain and itching on the skin.
