COMPLETE SPECIFICATION.
The Manufacture of an Improved Soap.
I, WILLIAM RALPH DODD, of No. 2, St. Andrews Pavement, Stamford Hill,
in the County of Middlesex, Pharmaceutical Chemist, 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 :-
This invention relates to the manufacture of a new or improved soap especially
applicable to the washing of the head and hair, but which is also of great value
as a medicinal soap in a variety of simple skin diseases as well as for ordinary use.
In manufacturing my improved soap I mix and combine soap, borax and
camphor in suitable proportions and preferably in the manner hereinafter more
particularly described.
I am aware that borax and camphor have been used and have been found of
extreme value for the aforesaid purposes but owing to the fact that camphor is
so sparingly soluble in water (to the extent of about half a grain in the ounce)
the valuable properties of camphor have not hitherto been realized to the full.
I have ascertained that the valuable properties of both camphor and borax
may be made available for personal use by mixing or blending or incorporating
them in a suitable kind of soap.
In order to obtain practically the full benefit of the borax and camphor I cause
them according to one method of carrying out my invention to be finely dis-
integrated and intimately mixed and evenly distributed through a soap by the process
known as milling in the soap trade. This mode of proceeding I prefer but in
some cases I make the soap by incorporating the disintegrated camphor and
borax by the process known as re-melting.
I have also found that when, in manufacturing my improved soap by the
milling process, I make use of curd soap, it soon develops a tallowy odour and in
order to remedy this defect I add an extra quantity of soda, potash or other lye
when mixing with the soap the other ingredients referred to.
For example in preparing this kind of soap I take say about eighty pounds
of curd soap from which the required quantity of water has been removed to
render it suitable for the milling process and with this soap I mix about ten
n

page_text: pounds of borax and about ten pounds of camphor together with a sufficiency of
soda or potash lye of 36° B. suitably perfuming the same, the whole is mixed by
suitable machinery and moulded into tablets by the process known as milling.
The above process of manufacture is that which I prefer as I have found it
to give good results in practice but I sometimes as above stated remelt ordinary
yellow or other soap and mechanically incorporate therewith the aforesaid
ingredients and form the soap into tablets in the ordinary way.
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 :-
The manufacture and use of the hereinbefore described new or improved soap.
