KREOLIN. 375

and very impure, with an odor liice tar ; and in its impure state
is slightly irritating, slightly caustic and strongly acid, and re-
sembles in its properties the phenols. A purified preparation of
creolin is, however, as neutral as vaseline, and quite as inoffen-
sive 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 solu-
tion.
Therapeutic Uses and Medical Properties.—Creolin is both anti-
septic, 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 germi-
cidal power is somewhat below that of carbolic acid. Its anti-
septic properties are powerful, and it is not irritating nor poison-
ous. 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: ^. Creolin, gr. iss ; aquae destil., TTLcl,
which may be applied with a brush or in the form of spray.
Dental Uses.—Yor 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 dis-
agreeable odors from the teeth and mouth. It will also hold in
check acid-producing germs; it is also recommended for its ac-
tion 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.
