TCP is a mild antiseptic, produced and sold in the United Kingdom by Pfizer. 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 sweet, medicinal odour can be identified by many as the generic smell of antiseptic.
The rights to TCP have been sold by Pfizer for "strategic reasons" to a Belgian company known as Omega Pharma.[1][2]
TCP can also be used as a mouthwash when diluted, and can also be used as a general disinfectant. Certain sources[1] suggest that when diluted it can be used as a vaginal douche, although the safety of this has not been fully ascertained.
Precautions
Care should be taken not to swallow large amounts of TCP as it may have an adverse effect on the kidneys. If one starts to feel unwell after using TCP, they should see a medical practitioner immediately. TCP should not be used on cats, as its phenol content makes it toxic to felines.[3]
Ingredients
TCP Liquid's active ingredients are halogenated phenols and phenol. (One source says each mL of TCP antiseptic contains, Chlorinated Phenols 6.0 mg; Phenol 1.75 mg; Iodinated Phenols 0.95 mg; Sodium Salicylate 0.5 mg.[2]) It also contains glycerol, concentrated phosphoric acid, E104 (quinoline yellow) and water.
