PROVISIONAL SPECIFICATION.
An Improved Manufacture or Preparation of Antiseptics.
We FREDERICK GEORGE ADAIR ROBERTS, ARTHUR SHEARER and WILLIAM
BRANTINGHAM GILES all of Wharton Road Stratford in the County of Essex
Manufacturing Chemists do hereby declare the nature of thus Invention to be as
follows:-
"
This Invention relates to the manufacture or preparation of antiseptics in a dry
form and consists in intimately mixing salicylic acid with an alkaline sulphite or
alkaline sulphites in a powdered state.
One of the chief obstacles to the ready use of salicylic acid as an antiseptic is its
insolubility in water beer wine or other fermentable liquors or watery fluids.
We have discovered that if salicylic acid be mixed in certain proportions in the dry
state with certain soluble sulphites also in the dry state and in powder the mixture or
compound so obtained dissolves readily and completely in the aforesaid fluids. The
sulphites most suitable for our purpose are soluble compounds of sulphurous anhydride
with the alkalies such as for instance Sulphite of Sodium Sulphite of Potassium or
Sulphite of ammonium and of these we by preference employ Sulphite of Sodium.
We preferably prepare the mixture or compound by triturating the constituents
together in say about equal proportions by weight but we do not confine ourselves to
such proportions. The product is a dry powder which is readily and conveniently
transportable and which readily dissolves in water beer wines or other termented
liquors or watery fluids

Manufacturing Chemists 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 or preparation of antiseptics in a dry form
and consists in intimately mixing salicylic acid with an alkaline sulphite or alkalino
sulphites.
One of the chief obstacles to the ready use of salicylic acid as an anuseptic is its
comparative insolubility in cold water beer wine or other fermentable liquors or watery
fluids.
We have discovered that if salicylic acid be mixed in certain proportions in the
dry state, with certain soluble sulphites also in the dry state and in powder the mixture
or compound so obtained dissolves readily and completely in the aforesaid fluids. The
sulphites most suitable for our purpose are soluble compounds of sulphurous
anhydride with the alkalies such as for instance sulphite or double sulphite of
sodium sulphite of potassium or sulphite of ammonium and of these we by preference
employ sulphite of sodium.
We preferably prepare the mixture or compound by triturating the constituents
together in say about equal proportion by weight but we do not confine ourselves to
such proportion. The product is a dry powder which is readily and conveniently
transportable and which readily dissolves in cold water beer wines or other fermented
liquors or watery fluids.

page_text: The following is the best way with which we are acquainted for carrying this
Invention into effect :-
We take ordinary sulphite of solium (Na, SO, 7 Aq.) and subject it to heat (pre-
ferably a temperature of from 212° to 300° Fahrenheit) until it becomes dehydrated
sulphite of sodium (Na, SO.). To this after reducing to powder by grinding if
necessary we then add-about-an-equal-proportion of salicylic acid, and thoroughly
Incorporate the ingredients preferably by trituration. The dry product can be formed
into tabloids or be put into packets and be dissolved when required for use.
Having now particularly described and ascertained the nature of our sud
Invention and in what manner the same is-to-be performed-we- declare, that what
we claim is:
1. The manufacture or production of an antiseptic by mixing soluble sulphite in a
dry state such as sulphite or double sulphite of sodium, sulphite of potassium or,
sulphite of ammonium with salicylic acid in a dry state substantially as her einbefore
<described.
2. The manufacture or preparation of an antiseptic by taking sulphite or double
sulphite of sodium (or of potassium) and dehydrating it and then mixing or
the same with dry salicylic acid substantially as herein before described.
turating
3. As a new article of manufacture an antiseptic in a dry or solid form prepared
substantially as hereinbefore described and clanned.
