PROVISIONAL SPECIFICATION.
Improvements in Soap and Plaisters.
Mrs. EDITH EMILY GILLAM 45 Penywern Road South Kensington S.W. do
hereby declare the nature of this invention to be as follows :-
For improvements in Soap and Plaisters.
:-
The object of my invention is the production of a disinfecting, antiseptic, anti-
spasmodic, and antifebrile soap, and plaister. In carrying this invention into effect I
combine with the soap while in its liquid state the essential oil known as "cajput" or
cajuput," either with or without a preparation of leaf, bark, or root of the "Melaleuca
Leucadendron ; or remelt the soap and combine the cajuput oil therewith, so that
when combined a new disinfectant, antiseptic, antispasmodic, and antifebrile soap
shall be produced.
"
The Plaister is similarly produced.
These productions I call respectively "Cajuputi Soap," and "Cajuputi Plaister."
These productions I call respectively "Cajuputi Soap," and "Cajuputi Plaister."
COMPLETE SPECIFICATION.
Improvements in Soap and Plaisters.
I EDITH EMILY GILLAM of 45 Penywern Road, South Kensington, London, S.W.,
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:-
The chief object of my invention is the production of a disinfecting, antiseptic,
anti-rheumatic, and antifebrile soap, suitable for use as a detergent of the skin.
It is applicable also in the production of plaisters for the removal of acute pain.
In the manufacture of a soap suitable for toilet use, 1 take, say, 100 parts, by
weight, of curd or pure soap, and this I steep in an essential oil known as cajuput or
cajeput oil prepared from the plant Mellaleuca Leucadendron.
The proportion of oil which I desire that the soap shall absorb, in the first instance,
is some 10% When the soap is thus saturated, I submit it to a milling operation,
by passing it through a roller mill composed of, say, two, three, or more pairs of
rollers, the action of which will be to amalgamate or thoroughly mix together the soap
and the essential oil. As some of the latter substance is, owing to its volatility, likely
to be lost, it is desirable that the soap shall contain not less than 10% of the oil when
submitted to the roller mill.
The mixture thus obtained may be moulded by pressure into slabs or other forms
suited for the market, and, if desired, these moulded pieces may be wrapt in tin foil to
prevent the loss of essential oil by evaporation.
For the production of a bath soap, proceed, in the first instance, as already
explained, and subsequently increase the proportion of the essential oil to, say, 20%-
This increased proportion of oil produces a compound more or less soft or viscid, and
therefore renders it desirable to introduce the manufactured soap into a metallic com-
pressible tube, when preparing it for the market, which covering will preserve it from
deterioration, and allow of its being expressed therefrom in the manner of artists'
colours.
In some cases, I may mix the leaves or bark of the Mellaleuca Leucadendron,
reduced to a pulverized state, with the more highly medicated soap, before submitting
the same to the roller mill.

page_text: This addition will render the soap more absorbent of the essential oil, and increase
the efficiency of its action upon the skin.
As this saponaceous compound is very efficient in removing rheumatic pains, I
propose to employ it as a plaister for the various parts of the body affected thereby,
and also for disorders of the chest arising from cold.
The plaister will be prepared in any well-known manner from the saponaceous
compound containing a percentage of essential oil of cajuput, equal or superior to that
of the bath soap.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, declare that what
I claim is
. The preparation of medicated soap as and for the purposes above described.
