Improvements in the Production of Solutions for Use as Anti-
septics, Disinfectants, Deodorants, Oxidants, and General
Sanitary Reagents.
I, CHARLES THOMAS KINGZETT, F.I.C., F.C.S., Vice President, Society of Public
Analysts, of "Trevena" Amhurst Park, London, do hereby declare the nature of this
invention to be as follows :-
In the course of investigations which I have conducted and accounts of which have
been published from time to time, I have ascertained that when spirits or Oil of
Turpentine, or Resin Spirit, or Cymene, or any essential oil containing a Terpene
(CH) is oxidised by air oxygen or ozone in the presence of water, there is
obtained an aqueous solution containing Peroxide of Hydrogen a substance which
exhibits peculiar antiseptic and oxidising properties and that this substance is
accompanied by others of a camphoraceous character which also exhibit antiseptic
properties.
This process of oxidation is now of commercial importance and is carried on under
Letters Patent granted to me and Maximilian Zingler, No. 274 of 1876.
My present invention relates to the same subject.
The first part concerns the apparatus employed in conducting the process of
oxidation previously referred to and consists in the employment of wooden, iron or
other vessels of suitable size and construction lined internally with pure metallic tin
and of perforated coils made of the same metal for the introduction of the current of
air oxygen or ozone into the mixture of Essential Oil or Hydrocarbon and water.
I have ascertained that this metal is not acted upon by the raw materials or the
manufactured products and its employment enables the manufacturer to use Oxidisers
of larger size and more convenient pattern than is otherwise practicable.
The second part relates to the process of manufacture and the products thereof and
consists in the employment of sea water (or its chemical equivalent made by dissolving
the substances found in sea water in ordinary fresh water) instead of ordinary water.
I have discovered that by the use of sea water the peroxide of hydrogen which is
produced in the process is not only not interfered with but is actually increased in
D

page_text: quantity and that the solution is more stable than that which is made with fresh water.
In other words the peroxide of hydrogen is preserved from chemical change.
Further, by the use of sea water new properties are given to the product its anti-
septic and preservative effects being thereby increased and the solution becomes
peculiarly applicable to a number of new sanitary and medical purposes.
The third part also partly relates to the process of manufacture and consists in the
employment of either fresh water or sea water charged with a proportion of any of
the following substances, viz: Borax, Phenol, Thymol, Lodoform, Camphoric acid,
Camphor, Cresol, Salicylic acid, Sulphophenic acid, Phenylpropionic acid, Phenylacetic
acid, Sulphuric acid or any antiseptic or disinfectant substance which is more or
less soluble in the fresh or sea water and which does not chemically react upon
the peroxide of hydrogen in the product. It is obvious that instead of charging the
water with these substances beforehand, they may be afterwards dissolved in the
aqueous solution resulting from the process of oxidation which I have described.
The advantage of this part of my invention is that the resulting products possess all
the advantages of the aqueous solution ordinarily resulting from the process of
oxidation as described while in addition they are fortified by the well known anti-
septic properties of the various added substances so far as they are dissolved in the
process of preparation, thus giving also a choice of active principles to the user.
As an alternative to the use of the solution of Peroxide of Hydrogen as prepared by
the oxidation of Turpentine or other suitable hydrocarbon, I can use peroxide of
hydrogen as prepared by other processes for admixture with the antiseptics and
disinfectants.

Improvements in the Production of Solutions for Use as Anti-
septics, Disinfectants, Deodorants, Oxidants, and General
Sanitary Reagents.
I, CHARLES THOMAS KINGZETT, F.I.C., F.C.S., Vice President Society of Public
Analysts, of "Trevena," Amhurst Park, London, 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 :-
In the course of investigations which I have conducted and accounts of which have
been published from time to time, I have ascertained that when Spirits or oil of
Turpentine, or Resin Spirit, or Cymene, or any essential oil containing a Terpene
(CH) is oxidised by air oxygen or ozone in the presence of water there is obtained
an aqueous solution containing Peroxide of Hydrogen, a substance which exhibits
peculiar antiseptic and oxidizing properties and that this substance is accompanied by
others of a camphoraceous character which also exhibit antiseptic properties."
This process of oxidation is now of commercial importance and is carried on under
Letters Patent granted to me and Maximilian Zingler, No. 274 of 1876.
My present invention relates in part to the same subject.
The first part concerns the apparatus employed in conducting the process of
oxidation previously referred to and consists instead of using oxidisers made of
earthenware as described in the English Patent above referred to, in the employment
of wooden, iron or other vessels of suitable size and construction lined internally with
pure metallic tin and of perforated coils made of the same metal for the introduction
of the current of air, oxygen or ozone into the mixture of Essential Oil or other
Hydrocarbon and water. I have ascertained that pure tin is not acted upon by the
raw materials or the manufactured product and its employment enables the manu-
facturer to use Oxidisers of larger size and more convenient pattern than is otherwise
practicable.
The second part relates to the process of manufacture and the products thereof and
consists in the employment of sea water (or its chemical equivalent made by dissolving
the substances found in sea water in ordinary fresh water) instead of ordinary water.
I have discovered that by the use of sea water the peroxide of hydrogen which is
produced in the process is not interfered with and that the solution is more stable
than that which is made with fresh water. In other words the peroxide of hydrogen
is preserved from chemical change. Further, by the use of sea water new properties
are given to the product its antiseptic and preservative effects being thereby increased
and the solution becomes peculiarly applicable to a number of new sanitary and
medical purposes.
The third part also partly relates to the process of manufacture and consists in the
employment of either fresh water or sea water charged with a proportion of any of
the following substances, viz-Borax, Phenol, Thymol, Iodoform, Camphoric Acid,

page_text: Camphor, Cresol, Salicylic acid, Sulphophenic acid, Phenylpropionic acid, Phenyl-
acetic acid, Sulphuric acid, or any other antiseptic or disinfectant substance
which is more or less soluble in the fresh or sea water and which does not
chemically react upon the peroxide of hydrogen in the product. It is obvious
that instead of charging the water with these substances beforehand, they may be
afterwards dissolved in the aqueous solution resulting from the process of oxidation
which I have described. The advantage of this part of my invention is that the resulting
'products possess all the advantages of the aqueous solution ordinarily resulting
from the process of oxidation as described while in addition they are fortified by the
well known antiseptic properties of the various added substances so far as they are
dissolved in the process of preparation, thus giving also a choice of active principles to
the user.
These active principles may be dissolved in any proportions (within their
limits of solubility) from one to ten per cent or upwards by weight in volume.
As an alternative to the use of the solution of Peroxide of Hydrogen as prepared by
the oxidation of Turpentine, or other suitable hydrocarbon, I can use peroxide of
hydrogen as prepared by other processes for admixture with the antiseptics and
disinfectants as described.
For example I take peroxide of hydrogen as made from peroxide of Barium by the
action of acids thereon, of such a strength as may be desired, say capable of evolving
five times its own volume of oxygen gas when decomposed as shown in the following
equation: H₂O₂ = H, O+ O and dissolve in it 5 per cent of perchloride of mercury
using also 5 per cent of common salt in order to preserve the mercuric compound
from decomposition when kept.
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
1. The use of oxidisers lined with pure tin for carrying on the process as first
described in the specification.
2. The process herein before described of manufacturing antiseptic, disinfecting,
deodorizing or oxidizing solutions consisting in oxidizing spirit or oil of turpentine
(or other essential oil containing cymene or a terpene) in presence of sea water or its
chemical equivalent.
3. The process herein before described of manufacturing antiseptic, disinfecting,
deodorizing or oxidizing solutions consisting in oxidizing spirit or oil of turpentine
(or other essential oil containing cymene or a terpene) in presence of water having
previously dissolved in it an antiseptic or disinfecting substance which will not
chemically react upon the peroxide of hydrogen obtained in the product.
4. The herein described composition of matter to be used for antiseptic disinfecting
deodorizing or oxidizing purposes consisting of an aqueous solution containing
peroxide of hydrogen and also having dissolved in it Borax, Phenol, Thymol
Todoform, Camphoric acid, Camphor, Cresol, Salicylic acid, Sulphophenic acid,
Phenylpropionic acid, Phenylacetic acid, Sulphuric acid or any other antiseptic or
disinfecting substance which is soluble in water and which does not chemically react
on the peroxide of hydrogen in the solution.
