Creolin is a liquid cresol, a product of the decomposition of coal tar.


It is obtained from English pit-coal by distillation, and is in the form of a brownish, syrupy liquid, complex and very impure, with an odor like tar; and in its impure state is slightly irritating, slightly caustic and strongly acid, and resembles in its properties the phenols. A purified preparation of creolin is, however, as neutral as vaseline, and quite as inoffensive to man and animals. It is slightly soluble in water, but soluble in ether, chloroform, and absolute alcohol; in the form of an emulsion it is as efficacious as an antiseptic as a true solution.

Therapeutic Uses And Medical Properties

Creolin is both antiseptic, germicide and hemostatic, being employed for the latter purpose in obstetrical practice; it is also used in tonsilitis. It is employed with great benefit in ulcers of the cornea. Its germicidal power is somewhat below that of carbolic acid. Its antiseptic properties are powerful, and it is not irritating nor poisonous. It is soluble in alcohol and glycerine, and it does not affect the skin nor corrode instruments, and the odor of the purified preparation is not disagreeable. It appears to have an anodyne effect, and is curative when applied to open wounds. Creolin has also been employed in antral disease. An aqueous solution of creolin is made of: R. Creolin, gr. iss; aquae destil., m cl, which may be applied with a brush or in the form of spray.

Dental Uses

For dental use it may be injected, or applied on floss-silk or cotton wool. Creolin is considered to be a good deodorizer of iodoform. One or two drops of creolin may be added to half a glass of water for a mouth wash, to correct disagreeable odors from the teeth and mouth. It will also hold in check acid-producing germs; it is also recommended for its action on mucous surfaces in soft and congested mouths, and to correct acid conditions, and in the treatment of fistulous tracts of suppurating surfaces; also in root canals to deodorize dead tissue. It will also remove the rust on instruments when applied by means of a felt wheel on a lathe. To sterilize instruments a two per cent. solution may be used; also on the hands, and a one per cent. solution for irrigation of wounds and treatment of mucous surfaces.
