COMPLETE SPECIFICATION.
A Superfatted Biniodide of Mercury Soap.
I, CHARLES RUMNEY ILLINGWORTH of 12 Baron's Court Road, West
Kensington, in the County of Middlesex, Doctor of Medicine, 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 consists of an improved medicated soap for use in cases of
infectious fevers, all contagious disorders of the skin, and similar purposes of
disinfection; and is a combination of any superfatted soap with a solution
of biniodide of mercury, this solution of biniodide of mercury having been ascer-
tained to be the most potent known germicide and of great value as a general
disinfectant. In order to prepare the soap according to this invention I take
properly measured ingredients of any suitable superfatted soap and submit them to
the usual process of saponification. When this is complete, and the soap has been
dehydrated I add a solution of the biniodide of mercury in a solution of the iodide
of potassium or sodium which I prepare in the following manner:-To a certain
weight of either finely powdered corrosive sublimate or the biniodide of mercury, I
add an excess of potassium or sodium iodide dissolved in water, until the red
precipitate is all dissolved and a more or less clear solution is formed. The solution
having been added to and thoroughly incorporated with, the superfatted soap, by
any suitable machinery, the mass is compressed for the purpose of stamping. I add
the solution prepared as above in the proportion preferably of from a half to one
per cent. of the mercurial salt, but I do not limit myself to these proportions as the
soap may be made stronger or weaker as desired.
This powerful and penetrating, yet non-irritant and non-poisonous soap, may be
put up either in a fluid form (or cream) for shaving purposes, or in the solid, and
preferably milled, form, for purposes of disinfection of any part of the body or of
any material whatsoever.

page_text: 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 :-
A combination of superfatted soap with a solution of biniodide of mercury
substantially as described.
