Synthol (mouthwash)

Synthol is a liquid medical product brand available in France since 1920, though the nature of the product has changed through the brand's history.

1920s

Synthol was developed by Maurice Bunau-Varilla, a prominent newspaper publisher of the early twentieth century, as a tonic. He promoted it as a cure-all tonic.[1]

Chloral hydrate based formula

The brand was acquired by GlaxoSmithKline.[2] Formerly the formula consisted of chloral hydrate, menthol, veratrol, resorcinol and salicylic acid. Sold mainly as a mouthwash in a distinctive black carton, it is also packaged as a gel and spray for the treatment of muscular pain(s).

Today

Following a rupture in supply 2014–2015[3] the product returned to French pharmacies in June 2016 with the same composition, minus chloral hydrate, now banned, and with the indication "mouthwash" («bain de bouche») removed.[4]

Among the new uses of the reformulation is endorsement of the Synthol gel as an umbilical cord antiseptic.[5]

SyntholKiné

A similarly named but unrelated product named SyntholKiné was launched by Glaxo in 2015.[6]
