COMPLETE SPECIFICATION.
An Improved Disinfectant or Composition for Antiseptic, Disinfecting,
Sanitary, and other Purposes.
I HERBERT HISCOTT of 56 and 57 Aldermanbury E.C. in the City of Loudon
Merchant, do hereby declare the nature of my said 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 consists of or relates to an improved disinfectant or composition
for antiseptic, disinfecting, sanitary and other purposes, and, by preference I
prepare the said composition in the fluid or semi-fluid form, although it may also,
if required, be solidified.
Having discovered that the antiseptic, disinfecting, and germ-destroying powers
of carbolic acid, cresylic acid, and what are known commercially as "tar-acids," or
"heavy-oils" are increased or enhanced by the presence of an alkaline fluoride,
silico-fluoride, or boro-fluoride (otherwise respectively called fluorate, fluo-silicate,
and fluo-borate) and also that in like manner the antiseptic and germ-destroying
powers of alkaline fluorides, silicofluorides and borofluorides are increased by the
presence of any of the tar-acids aforesaid or of their homologues. I take advantage
of the said discovery, for the purposes of this my invention by combining or mixing
a solution or emulsion of one or more of the said "tar-acids with a solution
or emulsion of one or more of the said alkaline fluorides, silico-fluorides or
boro-fluorides.
And I say that upon the principle herein recited I can prepare a compound or
compounds which is or are better adapted for; or are more powerful in action as
disinfectants and antiseptics than I can otherwise obtain from similar quantities of
either tar-acids or fluorides separately.
Now in order that my invention may be more clearly comprehended I will
proceed to describe more particularly the method of manufacture thereof. It must
however be distinctly understood that, inasmuch as different strengths and
consistencies of disinfecting compounds may be required, according to the purposes
for which they are intended, I do not confine myself to the precise details or
proportions which are here given, but may vary the same, from time to time as
required.

Thus for the preparation of one form of my improved disinfectant I take any
convenient weight of carbolic acid, or cresylic acid or any of their homologues,
whether under the name of "commercial carbolic acid," "crude phenol,"
acids or heavy tar-oils," and I dissolve, mix, or emulsify the same in the usual
manner by adding it slowly to from half, to nearly its own weight of resin or
colophony previously melted in a boiler or other suitable vessel, which, by preference
should be fitted with a mechanical paddle or stirrer. I further add a sufficiency of
a strong solution of caustic alkali, which may be either soda or potassa or (as I
prefer) a mixture of both. The exact proportions of resin and alkaline solution
requisite, depend upon the strength and quality of the tar-acids employed. A little
cotton-seed, or cocoa-nut oil soap, in quantity amounting to from four to eight
per cent. of the whole mixture may be added to assist the solution. Lastly when
the whole has become perfectly smooth and homogeneous, the alkaline fluoride,
silicofluoride, or borofluoride, (previously dissolved in a little hot water) may then
be added. Such fluoric salts may be either the fluoride of sodium or the fluoride
of potassium, or a silicofluoride, or borofluoride of either of the said alkaline

page_text: bases or of any other alkaline or earthy base provided always that the fluoric salt
or compound employed be a soluble one.
The proportion of the soluble fluoric salt or compound added, I regulate
according to the amount or percentage of soluble tar-acids or phenols intended to
lie present in my finished disinfectant compound, but for every hundred parts of
such soluble tar-acids or phenols used or taken, I add not less that ten parts of
such soluble fluoride or fifteen parts of such soluble silicofluoride or borofluoride.
Thus, for example if in the preparation of five hundred parts or pounds of my
improved disinfectant, one hundred parts or pounds of soluble tar-acids or phenola
are required or employed, I also add therein at least ten parts or pounds of
a soluble fluoride or fifteen parts or pounds of a soluble silicofluoride, or
borofluoride.
My invention thus prepared is in a fluid or semi-fluid state which is readily
soluble in or miscible with water and forms therewith an opalescent or milky
solution, enlsion, or mixture which even when extremely dilute is possessed of
very powerful disinfectant deodorant, nutiseptic, germicidal, insecticidal, and
detergent properties. Hence it may be employed for any purposes in which a
liquid or compound having such properties is necessary or expedient.
If my improved disinfectant be required in the solid form, in blocks, cakes, or
powder add thereto a sufficiency of any inert substance, such for instance as
infusorin earth, silica, plaster of Paris, sawdust or other suitable material to
effect the desired object.
For some purposes, such as the washing of infected linen, utensils or other
sanitary operations, I mix my improved disinfectant with a suitable proportion of
good soap and the said soap may then be advantageously used for such purposes
in place of ordinary soap.
And having now fully described and ascertained the nature, mode of preparation,
and application of my invention,- declare that what I claim is
The preparation of an improved disinfectant or composition for antiseptic,
disinfecting, sanitary and other purposes by the combination of, or admixture with
carbolic acid or other phenols tar-acids or heavy tar-oils, with alkaline, or other
soluble fluorides, silicofluorides, or borofluorides, upon the principles and
substantially according to the process and method hereinbefore recited and
described.
In witness whereof the said HERBERT HISCOTT have hereunto set my
hand and seal this Fifteenth day of October, in the year of our Lord
One thousand eight hundred and ninety-five.
HERBERT HISCOTT.
