This procedure can result in chronic ingrown nails causing more pain. Accordingly, in some cases as determined by a doctor, the nail matrix is coated with a chemical (usually phenol) so none of the nail will ever grow back. This is known as a permanent or full nail avulsion, or full matrixectomy, phenolisation, or full phenol avulsion. As can ...
While ingrown nails can occur in the nails of both the hands and the feet, they occur most commonly with the toenails (as opposed to fingernails). [citation needed] A common misconception is that the cause of an ingrown toenail is the nail growing into the paronychium, but it can also be caused by overgrown toe skin. [2]
Phenol spray, with phenol as the active ingredient, is used medically to treat sore throat. [38] It is the active ingredient in some oral analgesics. [38] Concentrated phenol liquids are used for permanent treatment of ingrown toe and finger nails, a procedure known as a chemical matrixectomy. The procedure was first described by Otto Boll in 1945.

TCP Liquid's active ingredients are halogenated phenols and phenol. One source says each millilitre (0.04 imp fl oz; 0.03 US fl oz) of TCP antiseptic contains, chlorinated phenols 6 milligrams (0.093 grains ); phenol 1.75 mg (0.0270 gr); iodinated phenols 0.95 mg (0.0147 gr); sodium salicylate 0.5 mg (0.0077 gr).

Step 1: Protonation of the phenol group Acetic anhydride is a source of acetyl cation (CH 3 CO +). In the presence of a Lewis acid catalyst like sulfuric acid, the acetyl cation can react with the lone pair of electrons on the oxygen atom of the phenol group of p-Chlorocresol to protonate it, forming a resonance-stabilized carbocation intermediate.
Their role is supposed to involve negotiating the cost of drugs to save patients money, but critics contend they are actually driving costs up. The U.S. Department of Health and Human Services ...
Chloroxylenol, also known as para-chloro-meta-xylenol (PCMX), is a chlorine substituted phenol with a white to off-white appearance and a phenolic odor.. The discovery of chloroxylenol was the result of efforts to produce improved antiseptics that began at the end of the 1800s, when scientists gradually realized that more substituted and more lipophilic phenols are less toxic, less irritant ...
