COMPLETE SPECIFICATION filed by the said Henri Adrien Bonneville
at the Office of the Commissioners of Patents, with his Petition and
Declaration, on the 8th April 1867, pursuant to the 9th Section of
the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRI
ADRIEN BONNEVILLE, of the British and Foreign Patent Offices, 24, Ruc du
Mont Thabor, Paris, in the Empire of France, and 38, Porchester Terrace,
Bayswater, in the County of Middlesex, Patent Agent, send greeting.
WHEREAS I am in possession of an Invention for "A NEW AND IMPROVED
KIND OF SOAP," a communication from Emeric de Werchin,.a person resident
at No. 15, Rue d'Antin, in the City of Paris aforesaid,. Manufacturer, and
have petitioned Her Majesty to grant unto me, my executors, administrators,
and assigns, Her Royal Letters Patent for the same, and made solemn
Declaration that it is a communication.

page_text: NOW KNOW YE, that I, the said Henri Adrien Bonneville, do hereby
declare that the following Complete Specification under my hand and seal
fully describes and ascertains the nature of the Invention and the manner in
which the same is to be performed, that is to say:-
The Invention communicated to me relates to the manufacture of a kind of
soap which may be advantageously employed in the useful arts, such as the
washing of wool in grease or tissues in whole pieces, as well as for domestic
purposes. This soap possesses the property, by reason of the substances which
enter into its composition, of destroying the insects, larvæ, animalcula, miasms,
or morbific principles that these wools, tissues, and clothes may contain; it is
equally fit for household washings, the cleansing of habitations, ships, stables,
and all such like infected places. In fine, whilst possessing superior qualities
as a dissolvent, and presenting incontestable advantages over all the various
kinds of soaps now used in the useful arts and for household purposes, it is at
the same time anti-putrid in its effects, and consequently eminently hygienic.
The principal ingredient that enters into the composition of this soap is the
bark of the American quillai tree, the root of the Egyptian saponaria, the root
of the indigenous saponaria or the plant itself, and the root of the lychnis of
China, brought back by solution to the state of more or less concentrated
extracts. This soap is made by combining together one or several of these
extracts with one or several of the following anti-putrid, anti-morbific, anti-
venimous, insect-killing, and disinfecting substances -Phoenic acid, camphor,
chlorine, benzoine, aloes, turpentine, sulphur, honey, and dextrine. In order
to arrive at the composition of my soap 1 subject either one or the other or
some or all of the above-enumerated extracts to the action of a little hydro-
chloric acid, in order to take back the magnesian salts which tend to become
precipitated when the concentration attains 8° or 10°; when this con-
centration has reached 12° I add to the solution some hyposulfate of soda in
the proportion of four pounds to every hundredweight of solution; part of this
byposulfate discomposes itself without disengaging any sulphuric acid; I find
therefore some sulphur liberated, an insect-killing substance, which destroys
any morbific germs, insects, larvæ, or other impurities that these extracts may
contain, and the quality of which by this first operation is improved so far as
regards the object I have in view. After these preliminary operations I con-
centrate the solutions, until 15° by the test sirup, and when that degree of
concentration is attained I proceed to mix substances the combination of which
with the extracts forms the soap made according to my method. When
phoenic acid is used I mix with it from twenty to a hundred pounds or there-
abouts per hundred litres of juice, according to the usage it is intended to make

page_text: of this soap;
I then concentrate the mixture until completely dessicated.
When camphor is used, after having dissolved it in phoenic acid I mix it with
an amount which must not exceed one hundred grammes per litre of juice,
which I concentrate until dessication. When chloride is used I take chloride
of lime, which I mix in the proportion of a hundred grammes per kilo of juice;
I then proceed as with phoenic acid. When benzoin is used I dissolve its
resin in phoenic acid in the proportion of three hundred grammes for two
hundred grammes of the latter; I then mix this solution in the proportion of
fifty grammes per litre of juice; I then concentrate until dessication. When
aloes are used I proceed as with the resin of benzoin. When spirits of tur-
pentine are used I mix in the proportion of five hundred grammnes per litre of
juice; I then concentrate until dessication. When sulphur is used I dissolve
it in the proportion of twenty grammes per hundred grammes of spirits of
turpentine, and mix this solution in the proportion of three hundred grammes
per litre of juice; I then proceed as with the phoenic acid. When honey is
used I mix it in the proportion of five hundred grammes per litre of juice;
I then proceed as with the phoenic acid. Finally, when dextrine or its deriva-
tives is used I mix it with an amount which must not exceed five hundred
grammes per kilo of juice, and I then proceed as with the phoenic acid.
All the soaps obtained by the combinations above indicated are homogeneous,
table, and dissolve perfectly well in all sorts of hot or cold water, even in
sea water, whilst, in addition to their eminently dissolving properties, they
possess also the qualities of the substances incorporated, and by combining
them the properties of each are collectively brought together.
Having now described and particularly ascertained the nature of the said
Invention, and the manner in which the same is or may be used or carried
into effect, I wish it to be understood that I do not restrict myself to the exact
details berein-before given, as, for instance, if I prefer operating at the degrees
of concentration herein-before indicated by me, because the solutions thus
treated and the products obtained are less imperfect, more homogeneous, and
preserve much better the properties of the combined substances, still it does
not follow that these operations may not take place, though less perfectly, at
higher or lower degrees of concentration. I would observe, in conclusion, that
what I consider and therefore claim as new and original is, the combination of
the bark of the quillai tree, the root of the Egyptian saponaria, that of the
indigenous saponaria (the ordinary saponaria) of the plant itself, and the root
of the lychnis of China, taken separately or collectively, with one or several of
the ensuing substances:-Phoenic acid, camphor, chlorine, benzoin, aloes,
turpentine, sulphur, honey, dextrine, and all other such like analogous

page_text: substances, in order to obtain a soap, either in a siropy or solid state, possess-
ing the dissolving qualities of these extracts, and anti-putrid, anti-morbific,
anti-venimous, hygienic, or other qualities of the incorporated substances, or
the combination of the soaps together.
In witness whereof, I, the said Henri Adrien Bonneville, have hereunto
set my hand and seal, this Sixth day of April, in the year of our Lord
One thousand, eight bundred and sixty-seven.
