COMPLETE SPECIFICATION.
Improvements in the Manufacture of Soaps and Saponaceous
Compounds.
I JESSE ASCOUGH of Handsworth in the County of Stafford Gentleman do
reby declare the nature of this invention and in what manner the same is to be
formed, to be particularly described and ascertained in and by the following
statement :-
This invention relates to improvements in the manufacture of soaps and
saponaceous compounds by means of which their antiseptic properties are
increased.
The improvements consist mainly in the incorporation of the chemical element
boron as it exists in boracic, borate and biborate compounds preferably in a fluid
hot state in the case of hard soaps and in a warm solid or semi solid condition in
the case of dry or "powdery " saponaceous compounds and by such methods and
in such proportions that the tendency heretofore existing of the boron compound
to disassociate itself from the finished soap when exposed to damp especially so in
the case of hard soaps as also in regard to soap powders is avoided. By
developing and retaining according to this invention the antiseptic cleansing
purifying and decay arresting properties of the said boron element these
properties can be utilized to the best advantage in the manufacture of soaps
and saponaceous compounds especially in the case of hard soaps for washing:
tablet soaps for toilet purposes: mineral soaps for polishing sponge and brush
cleansing powders, tooth powder soaps, skin soap and toilet powders but even more
especially in the case of soap powders for general purposes and with or without
perfume for bathing toilet and other uses.
In carrying out my invention as applied to hard soaps (whether such soaps are
to be cut into bars or moulded into cakes or tablets) to be used for household or
toilet purposes, soap powders, washing powders and similar saponaceous compounds
in powder for general washing, for use in the household, the bath or in the toilet,
for cleaning sponges and brushes and for all cleansing purifying and sanitary
purposes take :-
Boracic acid in powder
Dry sodium carbonate
Water (boiling)
Tincal borate in fine powder

I place these substances in the proportions stated in a boiling pan and
occasionally stir the contents and heat gradually until the temperature of the
mass is sufficiently raised to hasten the process of dissolving the substances and
continue the stirring until effervescence has nearly ceased and chemical com-
bination approximately completed. I then (in the case of hard soaps) transfer
the proportion of two pounds of this boron compound while still hot and fluid to
each hundred weight of boiling soap already in any convenient vat or pan in the
course of manufacture according to any well known formula and when such soap is
nearing its finished condition in such soap vat or pan and I agitate, stir or move
about the contents of the said vat or pau until the soap and the boron compound
are thoroughly mixed. The finished soap is then cleansed and transferred to the

page_text: and to either the two first or to the last mentioned I add :-
Boracic acid in fine powder
Calcium borate

These ingredients are placed in the boiling pan and I proceed to combine them
and afterwards add the compound to the soap vat in which any ordinary ingredients
composing soap of this class are being treated or prepared in the usual manner in
the quantity and in like manner as above described in connection with the
manufacture of "hard" soaps according to this invention.
I do not bind myself to use the exact quantities of each of the various
ingredients herein mentioned as the same may be slightly varied without
departing from my invention. Nor do I claim the mere admixture of boron
compounds with soap and saponaceous substances but
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. In the manufacture of hard soaps the admixture therewith of boron com-
pounds in a hot and fluid state substantially as hereinbefore specified and for the
purposes stated.
2. In the manufacture of saponaceous compounds in a powdered condition the
admixture therewith of boron compounds in a warm state substantially as herein-
before specified and for the purposes stated.
3. In the manufacture of soaps and saponaceous compounds mixing combining
and incorporating with hard soaps for household or toilet purposes, soap powders,
washing powders, and similar saponaceous compounds in powder for general
washing for use in the household the bath or in the toilet, for cleaning sponges
and brushes and for all cleansing purifying and sanitary purposes, boracic acid,
tincal borate and dry sodium carbonate and water, or sodium crystal carbonate,
in about the proportions and in the manner hereinbefore specified.
4. In the manufacture of soaps and saponaceous compounds mixing, combining

page_text: and incorporating with mineral or polishing soaps boracic acid, calcium borate and
dry sodium carbonate and water or sodium crystal carbonate in about the
proportions and in the manner hereinbefore stated.
5. The improvements in the manufacture of soaps and saponaceous compounds
herein set forth.
