TOILET ROUGES.
Are prepared of different shades by mixing fine carmine with talc
powder, in different proportions, say, one drachm of carmine to two
ounces of talc, or one of carmine to three of talc, and so on. These
rouges are sold in powder, and also in cake or china pots; for the
latter the rouge is mixed with a minute portion of solution of gum
tragacanth. M. Titard prepares a great variety of rouges. In some
instances the coloring-matter of the cochineal is spread upon thick
paper and dried very gradually; it then assumes a beautiful green tint.
This curious optical effect is also observed in "pink saucers." What is
known as Chinese book rouge is evidently made in the same way, and has
been imported into this country for many years.
When the bronze green cards are moistened with a piece of damp cotton
wool, and applied to the lips or cheeks, the color assumes a beautiful
rosy hue. Common sorts of rouge, called "theatre rouge," are made from
the Brazil-wood lake; another kind is derived from the safflower
(_Carthamus tinctorius_); from this plant also is made
PINK SAUCERS.
The safflower is washed in water until the yellow coloring-matter is
removed; the carthamine or color principle is then dissolved out by a
weak solution of carbonate of soda; the coloring is then precipitated
into the saucers by the addition of sulphuric acid to the solution.
Cotton wool and crape being colored in the same way are used for the
same purpose, the former being sold as Spanish wool, the latter as
Cr�pon rouge.
SECTION XV.
TOOTH POWDERS AND MOUTH WASHES.
TOOTH powders, regarded as a means merely of cleansing the
teeth, are most commonly placed among cosmetics; but this should not be,
as they assist greatly in preserving a healthy and regular condition of
the dental machinery, and so aid in perfecting as much as possible the
act of mastication. In this manner, they may be considered as most
useful, although it is true, subordinate medicinal agents. By a careful
and prudent use of them, some of the most frequent causes of early loss
of the teeth may be prevented; these are, the deposition of tartar, the
swelling of the gums, and an undue acidity of the saliva. The effect
resulting from accumulation of the tartar is well known to most persons,
and it has been distinctly shown that swelling of the substance of the
gums will hasten the expulsion of the teeth from their sockets; and the
action of the saliva, if unduly acid, is known to be at least injurious,
if not destructive. Now, the daily employment of a tooth powder
sufficiently hard, so as to exert a tolerable degree of friction upon
the teeth, without, at the same time, injuring the enamel of the teeth,
will, in most cases, almost always prevent the tartar accumulating in
such a degree as to cause subsequent injury to the teeth; and a flaccid,
spongy, relaxed condition of the gums may be prevented or overcome by
adding to such a tooth powder, some tonic and astringent ingredient. A
tooth powder containing charcoal and cinchona bark, will accomplish
these results in most cases, and therefore dentists generally recommend
such. Still, there are objections to the use of charcoal; it is too hard
and resisting, its color is objectionable, and it is perfectly insoluble
by the saliva, it is apt to become lodged between the teeth, and there
to collect decomposing animal and vegetable matter around such particles
as may be fixed in this position. Cinchona bark, too, is often stringy,
and has a bitter, disagreeable taste. M. Mialhe highly recommends the
following formula:--
MIALHE'S TOOTH POWDER.
Sugar of milk, one thousand parts; lake, ten parts; pure tannin, fifteen
parts; oil of mint, oil of aniseed, and oil of orange flowers, so much
as to impart an agreeable flavor to the composition.
His directions for the preparation of this tooth powder, are, to rub
well the lake with the tannin, and gradually add the sugar of milk,
previously powdered and sifted; and lastly, the essential oils are to be
carefully mixed with the powdered substances. Experience has convinced
him of the efficacy of this tooth powder, the habitual employment of
which, will suffice to preserve the gums and teeth in a healthy state.
For those who are troubled with excessive relaxation and sponginess of
the gums, he recommends the following astringent preparation:--
