Camphorated and Carbolated Powders

A camphorated tooth powder may be made by leaving out the oil of winter-green in the first formula and adding l.5 ounces of powdered camphor.

Carbolated tooth powder may likewise be made with the first formula by substituting 2 drachms of liquefied carbolic acid for the oil of wintergreen. But the tooth powder gradually loses the odor and taste of the acid. It is not of much utility anyway, as the castile soap In the powder is of far greater antiseptic power than the small amount of carbolic acid that can safely be combined in a tooth powder. Soap is one of the best antiseptics.

Alkaline salts, borax, sodium bicarbonate, etc., are superfluous in a powder already containing soap. The only useful purpose they might serve is to correct acidity of the mouth, and that end can be reached much better by rinsing the mouth with a solution of sodium bicarbonate. Acids have no place in tooth powders, the French Codex to the contrary notwithstanding.
