Secaderm® is a registered trade mark of Wade Pharmaceuticals Ltd.

Warning: Although Secaderm works great (I still use it) it does contain nasty chemicals. I do not advise anyone to handle these substances, but there's one born every minute so I'll give you the information and hope that you heed the warnings. If you really must make your own, please make it without the phenol!

Secaderm Salve consists of:

Active ingredients:

  • Resin B.P. (Colophony) 26% w/w
  • Turpentine Oil 6.00%
  • Melaleuca Oil 5.6% (I think this is "tea tree oil")
  • Terebene 5.25%
  • Phenol B.P. 2.4% (toxic!)

    I don't know what the base 54.75% is but any pharmacist will. Maybe paraffin wax?

    Stock code: PL 0208/5007

    An Antiseptic analgesic treatment for boils, abscesses, whitlow and foot ailments.

    Directions: Apply Secaderm to the septic part and cover with a light dressing of gauze. Repeat treatment twice daily or as directed by your doctor.

    Orginally was made in England by Wade Pharmaceuticals Ltd., Witham, Essex, CM8 3AG. (A subsidiary of Radiol Chemicals Ltd.)

    Also was made in England by Fisons Consumer Health, 12 Derby Road, Loughborough, Leicestershire, LE11 0BB.


    Phenol is one of the nastiest things you can find in the lab. Small amounts can KILL. It causes burns, is absorbed through the skin, and takes out your kidneys.

    When working with more than say 10 ml phenol, always ensure there is a bottle of glycerol or PEG300 close by. If you are silly enough to spill some on you, absorb it with the glycerol or PEG before washing with lots and lots of water. Water alone just spreads the stuff around. Always wear gloves, always wear glasses and work behind a screen.

    In other words, be extremely cautious when making up these stocks. Better yet, get someone who knows what they're doing to do it.

    Buy phenol cast in the bottle, 100g maximum, Sigma catalogue #P1037. Once saturated, store under Tris at -20°C.



    Secaderm was banned for supply on subscription in 2003. I can't find a reason but the toxicity of Phenol is a probable cause. Please note that Terebene isn't a particularly nice chemical either!
