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.
TCP is currently[when?] 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.
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.
Published advice states that TCP should not be swallowed, and recommends drinking plenty of water if 30ml or more of TCP is swallowed, and seeking medical advice if discomfort persists. Phenolic compounds such as those in TCP are harmful to cats.
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).) It also contains glycerol, concentrated phosphoric acid, Quinoline Yellow WS and water. Formerly, when the product was manufactured by Unicliffe Ltd, the bottle label's list of ingredients stated, referring to the solution of halogenated phenolic bodies, "with partial elimination of the ionisable halides".
In the media
TCP was referred to numerous times in a running gag in Episode 2 of Series 2 of the BBC sitcom One Foot in the Grave, alluding to its distinctive and long-lasting odour. TCP was mentioned as an ingredient in a tonic in the film The Strange Case of the End of Civilization as We Know It (1977). In the 1963 Ian Fleming story Agent 007 in New York, James Bond laments the fact that one of his lovers always gargles with TCP after their trysts. TCP is used as the subject of a song by the same name on The Boys' 1978 album Alternative Chartbusters written by Honest John Plain. TCP is mentioned in the song "Obsessions" by Suede.
