Year: 1881

page_text: LETTERS PATENT to Charles Denton Abel, of No. 28, Southampton Buildings,
Chancery Lane, in the County of Middlesex, for an Invention of “A New
OR IMPROVED MANUFACTURE OF LIQUID ROUGE." A communication from
abroad by Moritz Alfred Adolf Ludwig Lade, of Berlin, in the German
Empire.
PROVISIONAL SPECIFICATION left by the said Charles Denton Abel at
the Office of the Commissioners of Patents on the 9th August 1881.
CHARLES DENTON ABEL, of No. 28, Southampton Buildings, Chancery Lane, in
the County of Middlesex. "A NEW OR IMPROVED MANUFACTURE OF LIQUID
ROUGE." [A communication from abroad by Moritz Alfred Adolf Ludwig Lade,
of Berlin, in the German Empire.]
Rouge as heretofore employed has always been in the form of powder, which on
repeated use has a very prejudical effect on the health, as it consists mostly of
white lead powder coloured with carmine.
"
It has been endeavoured to substitute zinc white for the white lead, but even
this obstructs the pores of the skin and has a more or less unhealthy action. With
actors who have to employ such cosmetics continually diseases of the eye also are
frequently caused thereby, and other symptoms of lead poisoning are produced.
The present Invention has for its object the production of a liquid rouge that
shall obviate the above disadvantages, in only colouring the surface of the skin
with a perfectly innocuous substance that leaves the pores free, and that also has
the advantage that it will not come off with mere wetting, but will wash off readily.
with warm soap and water.
For this purpose there is mainly employed a solution of eosin which is mixed
with other ingredients as follows:—
Distilled water is heated to from 85° to 105° Fahr., and to it is added a small
quantity of eosin. Experiment has shown that for rouge to be used in daylight

page_text: about one part by weight of eosin to 1250 parts of water is sufficient, while for
gaslight from two to four parts of eosin should be used with the same quantity of
water.
When the solution has been cooled down to the atmospheric temperature, about
twenty parts by weight of glycerine are added, and after intimate admixture
hereof about 750 parts of alcohol or other suitable antiseptic liquid is added, the
compound thus produced being if desired scented with some essential oil, varying
in proportion from one tenth of a part to three parts; or rose water may for this
purpose be used in place of distilled water.
The liquid rouge having been prepared as above described, it is filtered either
through paper or through carbon for removing any suspended impurities, after
which it is ready for use.

Having thus described the nature of the said Invention, and in what manner the
same is to be performed, as communicated to me by my foreign correspondent,
I claim,-
The herein described manufacture of liquid rouge, consisting in the admixture of
heated distilled water with or without scent with a small quantity of eosin, to
which mixture is added first glycerine and then alcohol or other antiseptic liquid,
substantially as set forth.
In witness, whereof, I, the said Charles Denton Abel, have hereunto set my
