Carbolic soap Carbolic soap Carbolic soap is a mildly antiseptic soap containing carbolic acid and/or cresylic acid, both of which are phenols derived from either coal tar or petroleum sources. In 1834, German chemist Friedlieb Ferdinand Runge discovered a phenol, now known as carbolic acid, which he derived in an impure form from coal tar. In August 1865, Dr. Joseph Lister, 1st Baron Lister applied a piece of lint dipped in carbolic acid solution onto the wound of an eleven-year-old boy at Glasgow Royal Infirmary, who had sustained a compound fracture after a cart wheel had passed over his leg.

Deoxycholic acid deoxycholic acid is approximately 2.4–4 mM. Sodium deoxycholate, the sodium salt of deoxycholic acid, is often used as a biological detergent to lyse cells and solubilise cellular and membrane components. Sodium deoxycholate mixed with phosphatidylcholine, is used in mesotherapy injections to produce lipolysis, and has been used as an alternative to surgical excision in the treatment of lipomas. Deoxycholates and bile acid derivatives in general are actively being studied as structures for incorporation in nanotechnology. They also have found application in microlithography as photoresistant components. In the United States, deoxycholic acid, under the trade name Kybella, is approved by the
