page_text: I, HIPPOLYTE RICHEZ, of 23, rue Lamartine, Paris, France, Chemist, do hereby
declare the nature of this invention to be as follows:-
To introduce into the ordinary cosmetics in bricks or sticks, pastes or pomatums,
tinctorial elements mineral or vegetable capable of producing a fast dye to the
beard and the hair such is the general and new principle of the present inven-
tion.
In the mineral order one proceeds in the following way; one first of all pre-
pares in a proper dissolvent ammonia, alcohol, glycerine and the like in the
smallest possible quantity, in order not to make the composition too soft, a solu-
tion of metallic salts in powder, which one desires to use such as salts of silver,
bismuth, lead, and all metallic salts in general, apt to produce on the beard and
hair sulphurets of a proper colour fit to resist air and light.
The quantity of mentioned salt depending as is clear on the more or less dark
colour, to be obtained, generally, namely: from 1 to 10 grs. per cosmetic of about
100 grs.
On the other hand one allows the fatty substance which serves for the making
of the ordinary cosmetics (hog fat, suet of oxen, sheep and the like) to be melted
in a waterbath combined or not with yellow or white wax, in the proportion
required for the necessary consistency.
While cooling the metallic solution is added and is stirred and kneaded in
order to obtain the greatest possible homogeneousness. Before completing, a
quantity of flowers of sulphur is added in proportion to the chemical equivalents.
The stirring is continued with so that the dividing of the sulphur in the product
be almost completed. While the substance is still in a sufficiently soft state, some
scent may be added and the cosmetic is cast in the usual manner or, if required
into a mould of any shape.
It will then prove sufficient to dye oneself by saturating ones beard and hair as
thoroughly as possible with the cosmetic thus acquired.
The sulphur being oxydized by the oxygen of air to a state of hyposulphuric
or sulphuric acid and precipitated (on head hair or beard) in sulphuret, the metal
thus employed imparting a substantial dye which passes from fair to black accord-
ing to the greater or lesser concentration and strength of the constitutive parts
present.
Amongst other salts nitrate of silver (or any other salt of the same metal) being
therefore principally used on account of its fitness in imparting a substantial dye
under the form indicated.
The above salt may be employed singly on account of its decomposing when
exposed to light and more rapidly when in contact with organic substances by
communicating to the latter the substantial colour required.
In this particular case the addition of sulphur being especially meant while

page_text: producing sulphuret of silver to prevent the reddish colour peculiar to the dye
when this salt is used singly. The adding of sulphur in, this particular case is
not to be dispensed with.
In the vegetable order one acts in a similar manner as above mentioned to make
the cosmetic digest all the natural substantial colours known, in the proportions
necessary for obtaining dyes from fair to black, except that then the sulphur is
aseless, these colours dyeing sometimes naturally with or sometimes without an
appropriate mordant.
The proportions to be given being infinite and well known to all dyers, but as
vehicle of the colours, the use of alcohol is to be preferred.
In the same way as for the base metallic colours, one employs in this case
amongst other colours picric acid as a ground colour, "weakened," according to
the expression applied to dyeing, by all other colors, red, violet, brown, so that it
imparts on the beard and head hair the different tints from fair to black.
This distinction is the result of the validity of tint and the great affinity of this
product for the beard and hair affinity and soundness ascertained after innumer-
able comparative tests.
In conclusion this product is not only employed in cosmetics but besides (and
the above mentioned included) in a liquid form that is to say as a generator of
different waters for dyeing the beard and hair.

L. DUVINAGE,
Agent for Application.
I, HIPPOLYTE RICHEZ, of 23, rue Lamartine, Paris, France, Chemist, do hereby
declare the nature of this invention, and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following state-
ment:-
My invention has for object to introduce tinctorial elements, mineral or vege-
table, into ordinary cosmetics in bricks or sticks, paste or pomatum; the said
elements being capable of imparting a fast dye to the beard or hair.
The mineral composition is proceeded with as follows: First of all, a solution of
any pulverized salt desired to be used, such as salts of silver, bismuth, lead and all
metallic salts in general, capable of imparting a proper dye to the beard or hair
and fit to resist the effects of air and light, is prepared in a suitable dissolvent,
such as ammonia, alcohol, glycerine and the like, in the smallest quantity possible,
so as not to make the composition to soft.
The quantity of said salt naturally depends upon the darkness of the colour to
be obtained, generally from 1 to 10 grs. per cosmetic of 50 grs.
On the other hand, the fatty substance (pig fat, suet of oxen, sheep and the
like) which serves for the making of ordinary cosmetic, is allowed to melt in a
water bath, combined or not with yellow or white wax in the proportion required
for the necessary consistency.
°
While cooling, the metallic solution is added and is stirred and kneaded in order
to obtain the greatest possible homogeneousness.
Before completing, a quantity of flower of sulphur is added. The stirring is
continued so that the diffusion of the sulphur in the product be almost completed.
While the substance is still in a sufficiently soft state, some scent may be added
and the cosmetic is cast in the usual way, or, if required in a mould of any shape.

page_text: To dye oneself it suffices to saturate one's beard or hair as thoroughly as possible
with the cosmetic thus obtained.
The sulphur being oxydized by the oxygen of air forms with the metal of the
salt employed, a sulphide which precipitates on the hair or beard, when the
cosmetic is used, imparting a substantial dye which passes from fair to black
according to the greater or lesser concentration and strength of the constituent
parts present.
Amongst other salts nitrate of silver (or any other salt of the same metal) is
principally used on account of its fitness in imparting a substantial dye under the
form indicated.
As an example of the composition of a mineral dyeing cosmetic I may give the
following: cosmetic (wax and fat) 25 grammes, nitrate of silver 25 grammes,
sulphur 027 gramme, glycerine 2 grammes.
In the vegetable order the above-mentioned process is adopted to make the
cosmetic digest all the natural substantial colours known, in the proportions
necessary for obtaining dyes from fair to black, except that, then, the sulphur
is useless..
The proportions to be given being indefinite and well known to all dyers, but
as conveyer of the colours the use of glycerine is preferable.
In the same way as for the ground metallic colours, one employs amongst other
colours picric acid as a ground-colour "weakened " according to the expression
applied to dyeing, by all other colours, red, violet, brown, so that it imparts to the
beard and hair the different tints from fair to black.
As example of the composition of a vegetable dyeing cosmetic, I may give the
following: cosmetic (wax and fat) 20 grammes, dyeing substance 1 gramme,
glycerine 1 gramme.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is:-
1
New dyes for the beard and the hair composed of cosmetics, pastes, or pomatums
to which are added metallic salts and sulphur or vegetable colours, substantially
as described.
