Improvements relating to the Manufacture of Perfumery.
We, PAUL HENRI LECORNU, of 105 Boulevard Magenta, Paris, Perfumer and
Chemist, and ANTOINE RAYNAUD of 53 Rue Gide, Levallois Perrer, Manufacturer of
Perfumery, both in France do hereby declare the nature of this invention to be as
follows:-
Our invention relates to the manufacture of perfumery in the form of sticks, blocks,
or the like, which are adapted to be rubbed against the articles to be perfumed in order
to impart their perfume thereto.
According to our said invention the essential oils, or the alcoholic extracts, tinctures,
or infusions of the materials from which the perfume is derived are incorporated with
substances, capable of absorbing and retaining them in more or less large quantities,
without however, in any manner, affecting the perfume thereof.
The most suitable absorbent substances are earthy, chalky or stony mineral
substances such as carbonate of lime, kaolin, porcelain clay, talc, or the like. In some
cases it is necessary in consequence of the physical nature of the perfume (essential oil
or alcoholic extract &c.) to give preference to certain substances. The selection which
can be made among these absorbent substances varies, moreover, according to the
durability which it is desired to obtain for the solid perfumes, that is to say according
to the more or less rapid wear of the stick, block or the like when in use.
The perfumes can be incorporated with the mineral absorbing substances, either by
simply soaking blocks, sticks, balls or the like of these mineral substances in the
perfumed alcoholic extracts, infusions, tinctures or the like; or by mixing the essential
oil or the alcoholic extract, infusion, tincture or the like with the minerai substances
in the form of powder a binding substance being subsequently added, so that the
mixture may be compressed or moulded to any desired shape.

page_text: The various modifications which are comprised in the manufacture of solid perfumes
will be easily understood from the examples which we give below.
1ST. MANUFACTURE OF A SOLID PERFUME HAVING A BASE OF ESSENTIAL OIL.
50 parts of pulverized carbonate of magnesia, and 50 parts of pulverized sulphate
of lime are intimately mixed and to the mixture is added water containing a little
starch or preferably a very thin solution of gum to form a very homogeneous paste.
The water may be employed in any proportion as it is subsequently evaporated. To
the paste thus formed is then added essential oil of the required perfume care being
taken to thoroughly mix the same.
"
The proportion of perfume added, especially in the case of essential oils which are
very costly, varies according to the price at which the product is to be sold, but
generally it forms at least 25% of the weight of the paste.
This perfumed paste we form into blocks, sticks, balls or the like, either by hand
upon marble tables, or in moulds where it is firmly compressed, the said blocks, sticks
or the like being finally loft for the required time to dry.
The absorbing earthy substances which we preferably employ by preference for the
manufacture of solid perfumes having a base of essential oils are: carbonate of
magnesia, sulphate of lime (alabaster, gypsum, etc.) and phosphate of lime, either
alone or mixed in proportions which vary according to the nature and the quantity of
essential oils to be absorbed and to the durability of the product to be obtained.
These substances readily absorb these essential oils and are assimilated therewith so as
to neutralize their oily principles.
2. MANUFACTURE OF A SOLID PERFUME HAVING A BASE OF ALCOHOLIC EXTRACT,
INFUSION, TINOTURE ETC.
A paste composed of 25 per cent. of powdered phosphate of lime, and 75 per cent. of
powdered carbonate of lime is made to which is added gummed water or any other
suitable binding substance. This paste is then left to dry after having been formed
into blocks, sticks, or the like. When the said blocks, sticks or the like are perfectly
dry they are plunged into the desired alcoholic extract infusion or tincture. After the
said blocks, sticks or the like have been immersed for a sufficient time to soak or
impregnate them with perfume, they are withdrawn and dried again.
3RD. MANUFACTURE OF A SOLID PERFUME HAVING A BASE OF ESSENTIAL OIL
COMBINED WITH AN ALCOHOLIC INFUSION, EXTRACT OR TINCTURE.
The perfume which is a mixture of essential oil, and of an alcoholic extract, tincture
or infusion is first prepared. This done 75 per cent. of pulverized carbonate of lime
and 25 per cent. of pulverized carbonate of magnesia are taken, and after the perfect
mixing of these two powders, a homogeneous paste is formed, to which the desired
cohesion is given by the addition of a binding material, as herein before described.
The perfume is then introduced, either directly by mixing it with the paste before the
moulding, or after the moulding, by soaking the blocks, sticks or the like for some
time in the mixture of essential oil and alcoholic extract tincture or infusion.
By this mode of operation we prepare compound perfume, for example that known
by the name of musked rose.
It is to be understood that these three modes of manufacture are applicable
irrespective of the number of essential oils, and alcoholic extracts, tinctures or infusions
which are to constitute the perfume.
As regards the arbsorbing substances mentioned they can be replaced by kaolin
porcelain clay, talc, or any other suitable earthy silicate, either simple or compound.

page_text: Into the composition of the sticks or blocks may likewise be introduced substances
capable of overcoming the dryness of the earthy substances, and of imparting to them
greater oiliness to the touch, such as paraffin spermaceti, oxide of zinc or the like.
As we have stated above these solid perfumes can be moulded into any desirable
shapes and enclosed in casings or boxes of wood or other suitable material.
To perfume linen articles, envelopes visiting cards or the like with this solid perfume
it is sufficient to pass the stick or block over the articles slightly rubbing them.
By this friction, particles of the material of the said stick or block are detached
therefrom, and deposit the perfume which is incorporated therein upon the article to
be perfumed without sullying or wetting it.
Instead of preparing special agglomerates for the manufacture of these perfumed
sticks or blocks, the latter can be cut from natural earthy minerals, such as, for
instance chalk the pieces thus prepared being soaked for some time in essential oil,
alcoholic extract, infusion or tincture, or in the mixture of essential oil and alcoholic
extract, infusion or tincture.
Our blocks sticks or the like can be coloured in any shade by introducing suitable
colouring matters into the paste which composes them or into the perfume which is
absorbed by this paste.

Improvements relating to the Manufacture of Perfumery.
We, PAUL HENRI LECORNU, of 105 Boulevard Magenta, Paris, Perfumer and
Chemist, and ANTOINE RAYNAUD, of 53 Rue Gide, Levallois Perrer, Manufacturer
of Perfumery, both in France do hereby declare the nature of this invention and in
what manner
the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
Our invention relates to the manufacture of perfumes in the form of sticks, blocks,
or the like which are adapted to be rubbed against the articles to be perfumed in order
to impart their perfume thereto.
According to our invention the essential oils, or the alcoholic extracts, tinctures, or
infusions of the materials from which the perfume is derived are incorporated with
substances capable of absorbing and retaining them in more or less large quantities
without, however, in any manner affecting the perfume thereof.
The most suitable absorbent substances are earthy, chalky, or stony mineral sub-
stances; such as carbonate of lime, kaolin, porcelain, clay, talc, or the like; in some cases
it is necessary in consequence of the physical nature of the perfume (essential oil or
alcoholic extract) to give preference to certain substances. The selection which can be
made among these absorbent substances varies, moreover according to the durability
which it is desired to obtain for the solid perfumes, that is to say according to the more
or less rapid wear of the stick, block, or the like when in use.
The perfumes can be incorporated with the mineral absorbing substances, either by
simply soaking blocks, sticks, balls, or the like of these mineral substances in the
perfumed alcoholic extracts, infusions, tinctures or the like; or by mixing the essential
oil or the alcoholic extract, infusion, tincture or the like with the mineral substances
in the form of powder, a binding substance being subsequently added, so that the
mixture may be compressed or moulded to any desired shape.
The various modifications which are comprised in the manufacture of solid perfumes
will be easily understood from the examples which we give below.
FIRST. MANUFACTURE OF A SOLID PERFUME HAVING A BASE OF ESSENTIAL OIL.
50 parts of pulverized carbonate of magnesia and 50 parts of pulverized sulphate
of lime are intimately mixed and to the mixture is added water containing a little
starch, or preferably a very thin solution of gum to form a very homogeneous paste.

the paste thus formed is then added essential oil of the required perfume, care being
taken to thoroughly mix the same.

SECOND. MANUFACTURE OF A SOLID PERFUME HAVING A BASE OF ALCOHOLIC
EXTRACT, INFUSION, TINCTURE ETC.
A paste composed of 25% of powdered phosphate of lime and 75% of powdered
carbonate of line is made, to which is added gummed water or any other suitable
binding substance. This paste is then left to dry after having been formed into blocks,
sticks, or the like. When the said blocks, sticks or the like are perfectly dry they are
plunged into the desired alcoholic extract, infusion, or tincture.
After the said blocks, sticks, or the like have been immersed for a sufficient time to
soak or impregnate them with perfume; they are withdrawn and dried again.
THIRD. MANUFACTURE OF A SOLID PERFUME HAVING A BASE OF ESSENTIAL OIL
COMBINED WITH AN ALCOHOLIC INFUSION, EXTRACT, OR TINCTURE.
The perfume which is a mixture of essential oil, and of an alcoholic extract, tincture,
or infusion is first prepared. This done, 75% of pulverized carbonate of lime and
25% of pulverized carbonate of magnesia are taken, and after the perfect mixing of
these two powders a homogeneous paste is formed, to which the desired cohesion is
given by the addition of abinding material, as herein-before described. The perfume
is then introduced, either directly by mixing it with the paste before the moulding, or
after the moulding, by soaking the blocks, sticks, or the like for some time in the
mixture of essential oil and alcoholic extract tincture or infusion.
By this mode of operation we can prepare a compound perfume, for example that
known by the name of musked rose.
It is to be understood that these three modes of manufacture are applicable
irrespective of the number of essential oils, and alcoholic extracts, tinctures or
infusions which are to constitute the perfume.
As regards the absorbing substances mentioned they can be replaced by kaolin,
porcelain clay, talc or any other suitable earthy silicate, either simple or compound.
Into the composition of. the sticks or blocks may likewise be introduced substances
capable of overcoming the dryness of the earthy substances, and of imparting to them
greater oiliness. to the touch, such as paraffin, spermaceti, oxide of zinc or the
like.
As we have stated above, these solid perfumes can be moulded into any desirable
shapes. By way of example we have represented in the accompanying drawing a
crayon perfume having an oval end, and enclosed in casings or boxes of wood or other
suitable material.
To perfume linen articles, envelopes, visiting cards or the like, with this solid
perfume it is sufficient to pass the stick or block over the articles lightly rubbing them.
By this friction, particles of the material of the said stick or block are detached there-
from, and deposit the perfume which is incorporated therein upon the article to be
perfumed without sullying or wetting it.
Instead of preparing special agglomerates for the manufacture of these perfumed
sticks or blocks, the latter can be cut from natural earthy minerals, such as, for instance,

page_text: chalk, the pieces thus prepared being soaked for some time in essential oil, alcoholic
extract, infusion, or tincture or in the mixture of essential oil and alcoholic extract,
infusion or tincture.
Our blocks sticks or the like can be coloured in any shade by introducing suitable
colouring matters into the paste which composes them or into the perfume which is
absorbed by this paste.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed we declare that what we claim is
First. The manufacture of perfumery in the shape of blocks, sticks or the like from
earthy substances which are caused to absorb any perfume which they can impart to
other bodies, such as linen articles, envelopes, letter-paper, visiting cards and the like
without wetting them, by depositing thereon particles of their constitutive material
by rubbing the said blocks or sticks upon the article to be perfumed as above
described.
Second. The incorporation of essential oils, or mixtures of essential oils of alcoholic
extracts, infusions, or tinctures in earthy substances which serve as a base for the
perfumed blocks, sticks or the like, the intimate mixing of these oils or mixtures of oils
and of alcoholic extracts, infusions or tinctures with a paste formed of earthy substances
to which is added a suitable binding material, and the ulterior moulding of this paste
into any desirable shape as above described.
Third. The preparation of blocks, sticks or the like of earthy substances by moulding
through the medium of a paste formed of earthy substances to which a suitable
binding material is added, these blocks, sticks or the like, absorbing the perfume by
simple immersion in alcoholic extracts, infusions or tinctures, or in a mixture of
essential oils and alcoholic extracts, infusions or tinctures as above described.
Fourth. The preparation of blocks, sticks or the like of earthy substances by
cutting them from natural earthy minerals, such as chalk, and the ulterior immersion
of these crayons in alcoholic extracts infusions or tinctures or in a mixture of essential
oils and of alcoholic extracts, infusions or tinctures, with the object of causing them to
absorb the perfume as above described.
