Why Dettol Burns When You Apply It on Wounds

 Dettol is one of the most common antiseptics we use at home, but almost everyone feels a sharp burn when they put it on a cut. This reaction is normal and happens because Dettol contains strong germ-killing ingredients. When these ingredients touch broken skin, the exposed nerve endings react immediately, which creates the burning feeling.



The main antiseptic in Dettol is chloroxylenol. It kills bacteria effectively, but it also irritates fresh wounds for a few seconds. Dettol may also contain alcohol, which adds to the sting because alcohol evaporates quickly and tends to irritate open skin. Fresh cuts are already inflamed, so even a mild antiseptic can feel aggressive when applied.

The burning sensation usually settles in a short time. It doesn’t mean the wound is getting worse. If the cut is large or if someone has very sensitive skin, using saline water or a mild antiseptic wash is a more comfortable choice.
