Improvements in the Manufacture of Soap.
JAMES WILLIAM BARCLAY 41 West Chislehurst Park Eltham Kent Gentleman,
do hereby declare the nature of this invention to be as follows:-
The object of this invention is an improved method for the manufacture of soap
whereby a large or small amount of unsaponifiable or other oils may be incorporated
with soap.
In order to effect this, the unsaponifiable oil (or other oil or oils) is first
solidified or rendered pasty or thickened by any convenient process or by any
known method, such as, treating with resin and alkali, or mixing with a sufficient
amount of resin or other soap, or by a combination of both methods. These
thickening or solidifying processes are applicable to petrolium, coal oil or other
mineral or unsaponifiable oil, and such oils are capable of being so treated and
used for the purposes of this invention.
The oil (or oils) solidified or thickened by such a process as that referred to is
then mixed in any desired proportion with any suitable soap-making materials such
as tallow and other fats, cocoanut and other oils &c. and the whole treated with
alkaline ley and made into soap in the usual manner.
A
The oil (or oils) in the solid or thickened form may be added to any soap at any
stage in the course of manufacture, for instance, they may be added to the boiling
soap or if preferred may be crutched into the finished soap or into remelted soap.
By this method of manufacture a much better and more homogenous soap can be
made than if plain liquid oil be used.
The soap so made may be used as an insecticide and may be diluted with or
dissolved in water for use for this purpose or for use as a disinfectant if coal oil or
similar oil has been used.
Several processes of solidifying oils are known but to make the meaning clearer
it may be instanced that the processes referred to would include such as those
described in Patents Nos. 4446 of 1891 and 952 of 1892.
Dated this Eighth day of October 1895
I JAMES WILLIAM BARCLAY, Chartered Accountant, of 41 West Chislehurst
Park Eltham in the County of Kent 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 :-
My invention relates to an improved method for the manufacture of soap whereby
a small or large amount of unsaponifiable or other oils may be incorporated with
soap.
In order to effect this, the unsaponifiable oil (or other oil or oils) is first
solidified or rendered pasty or thickened by any convenient process or by any known

of resin or other soap, or by a combination of both methods. These thickening or
solidifying processes are applicable to petroleum, coal oil or other mineral or
unsaponifiable oil, and such oils are capable of being so treated and used for the
purposes of this invention.
For example a convenient method is to dissolve in, say, an ordinary soap-pan
about 1 cwt, of rosin in about 2 cwts. of the warm oil or oils to be used, thereafter
the mixture is agitated and about 5 gallons of saturated soda lye is run in until
the whole becomes a pasty mass.
Another plan is to crutch in 1 cwt. of the warm oil or oils into 2 cwts. of any
melted soap till n complete mixture is obtained.
I do not however limit myself to these but may employ any known process.
The oil (or oils) solidified or thickened by a process such as above referred to is
then mixed in any desired proportion with any suitable soap-making materials such
as tallow and other fats cocoanut and other oils &c., and the whole treated with
alkaline ley and made into soap in the usual manner.
The oil (or oils) in the solid or thickened form may be added to any soap at any
stage in the course of manufacture, for instance, they may be added to the boiling
soap or if preferred may be crutched into the finished soap or into the remelted
вопр.
By this method of manufacture a much better and more homogeneous soap can
be made than if plain liquid oil be used.
The soap so made may be used as an insecticide and may be diluted with or
dissolved in water for use for this purpose or for use as a disinfectant if coal oil or
similar oil has been used.
The relative proportions may be varied according to the quality of the soap
desired. For disinfectant purposes about equal parts of the solidified oil or oils
and soap may be used. The oils for this purpose should consist principally of some
disinfectant such as coal oil or cresylic acid but any disinfectant (such as thymnol)
soluble in mineral oil may be employed; in the Inst noted case the disinfectant
should be dissolved in the oil before solidification.
To make a liquid disinfectant the foregoing proportions should be increased
to 80 or 90% of solidified oil and 20 to 10% of soap (preferably soft soap) the
whole being diluted with water to any desired strength such a solution containing
petroleum or paraffin oil is a useful insecticide.
Having now particularly described and ascertained the nature of this inveu-
tion and in what manner the same is to be performed I declare that what I
claim is-
1. The herein before described improvement in the manufacture of soap by
combining solidified or thickened uusaponifiable oil or oils with soap making
materials or with ordinary soap at any desired step of its manufacture substantially
as set forth.
2. The hereinbefore described process of solidifying mineral oil by mixing with
resin and alkali substantially as set forth.
3. The hereinbefore described manufacture of a disinfectant soap or fluid from
a disinfectant oil or disinfectant substance soluble in mineral oil substantially as
set forth.
4. The hereinbefore described manufacture of an insecticide sonp or fluid
substantially as set forth.
