TCP (antiseptic)

TCP (antiseptic) is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand TCP (antiseptic) rather than just read about it. In short: TCP is a mild antiseptic, produced in France by Laboratoires Chemineau in Vouvray and sold in the United Kingdom by Omega Pharma. Introduced in 1918, the brand name comes from its original chemical name, which was trichlorophenylmethyliodosalicyl.

Key takeaways

  • TCP (antiseptic) belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect TCP (antiseptic) to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of TCP (antiseptic) from memory before moving on to harder problems.

Reference excerpt

TCP is a mild antiseptic, produced in France by Laboratoires Chemineau in Vouvray and sold in the United Kingdom by Omega Pharma. Introduced in 1918, the brand name comes from its original chemical name, which was trichlorophenylmethyliodosalicyl. The liquid form of TCP is one of the best-known brands of antiseptic in the UK, and its distinctively strong medicinal odour can be identified by many as a generic antiseptic smell.

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

Forms As of October 2013, TCP was 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. A TCP throat lozenge is also available. TCP was available formerly as an ointment, TCP Original Antiseptic Ointment 30 g. A spray plaster was or is available under the TCP brand.

Uses 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.

Harmful effects 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.

Ingredients 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 popular culture 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. In the Black Mirror episode Metalhead (series 4 episode 5), a broken bottle of TCP is seen being pulled out of a backpack in advance of minor surgery. A bottle of TCP is also briefly seen in the film Shallow Grave (1994) in the scene following Ewan McGregor's character Alex being beaten up. It was also referenced in TV sitcom ‘’Only Fools and Horses’’ where lead character Del Boy is said to have treated a stab wound with “TCP and a flannel”, owing to his fear of hospitals. In Series 7, Episode 1 of Call the Midwife, Christopher tells Trixie that he got something for her while he was at the cash and carry. Trixie responds, “What? Six packets of corn plasters and a bottle of TCP?”

Worked examples

Example 1 — a first encounter with TCP (antiseptic)

Start with the simplest possible case. Write down what TCP (antiseptic) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to TCP (antiseptic) before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about TCP (antiseptic) ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of TCP (antiseptic)

In research
TCP (antiseptic) appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses TCP (antiseptic) in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
TCP (antiseptic) is common in secondary-school and first-year university syllabi. It links to neighbouring topics Antiseptics, Products introduced in 1918, so understanding it makes those chapters shorter.
In everyday life
Look for TCP (antiseptic) outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
