Coloring Perfumes
Chlorophyll
is a suitable agent for coloring liquid perfumes green. Care must be taken
to procure an
article freely soluble in the menstruum. As found in the
market it is prepared (in form of solutions) for
use in liquids strongly
alcoholic; in water or weak alcohol; and in oils. Aniline greens of various
kinds
will answer the same purpose, but in a trial of any one of these it
must be noted that very small
quantities should be used, as their tinctorial
power is so great that liquids in which they are incautiously
used may stain
the handkerchief.
Color
imparted by chlorophyll will be found fairly permanent; this term is a
relative one and not too
much must be expected. Colors which may suffer but
little change by long exposure to diffused light
may fade perceptibly by
short exposure to the direct light of the sun.
Chlorophyll
may be purchased or it may be prepared a follows: Digest leaves of grass,
nettles, spinach, or other greet
herb in warm water until soft; pour off the
water and crust herb to a pulp. Boil the pulp for a short time with
a half
per cent solution of caustic soda, and afterwards precipitate the
chlorophyll by means of dilute hydrochloric
acid; wash the precipitate
thoroughly with water, press and dry it, and use as much for the solution as
may be
necessary. Or a tincture made from grass as follows may be employed:
Lawn grass,
cut fine
... 2 ounces
Alcohol
..... 16 ounces
Put the
grass in a wide mouthed bottle, and pour the alcohol upon it. After standing
a few days, agitating occasionally,
pour off the liquid, the tincure may be
used with both alcoholic and aqueous preparations.
Among the
anilines, spirit soluble malachite green has been recommended.
A purple or
violet tint may be produced by using tincture of litmus or ammoniated
cochineal coloring. The former is made
as follows:
Litmus
.
2½ ounces
Boiling water
.
. 16 ounces
Alcohol
... 3 ounces
Pour the
water upon the litmus, stir well, allow standing for about an hour, stirring
occasionally, filter, and to the filtrate
add the alcohol.
