TCP (antiseptic)

TCP is a mild antiseptic, produced in France by Laboratoires Chemineau in Vouvray and sold in the United Kingdom by Omega Pharma.

TCP was introduced in 1918. The brand name comes from its original chemical name, which was trichlorophenylmethyliodosalicyl (not to be confused with trichlorophenol, a common fungicide). Trichlorophenylmethyliodosalicyl was replaced as the active ingredient by a mixture of phenol and halogenated phenols in the 1950s. The liquid form of TCP is one of the most well-known brands of antiseptic in the UK, and its distinctive overbearing medicinal odour can be identified by many as a generic antiseptic smell.

Omega Pharma acquired the rights to TCP from Pfizer in 2004.

TCP is currently available in 50-millilitre (1.8 imp fl oz; 1.7 US fl oz), 100 ml (3.5 imp fl oz; 3.4 US fl oz), 200 ml (7.0 imp fl oz; 6.8 US fl oz) and 500 ml (18 imp fl oz; 17 US fl oz) bottles as a clear yellow liquid. It is also available as throat lozenges, and was formerly available as a cream.

A spray plaster was or is available under the TCP brand.

The instructions on the TCP bottle state that TCP can be used for sore throats, mouth ulcers, cuts, grazes, bites and stings, boils, spots and pimples.

It can also be used as a mouthwash when diluted, and can also be used as a general disinfectant. A Pfizer representative in South Africa stated that if diluted, it can be used as a vaginal douche, although the safety of this has not been fully ascertained.
