Improvements in the Manufacture of Disinfecting Preparations.
I, GEORGE DAWSON, of 18 Miller Street, Reddish, near Stockport, in the
County of Lancaster, Foreman of Chemical Works, 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 object and nature of this invention is to gelatinize or make into more or less
stiff pastes the concentrated liquid mixtures of the phenol series of tar acids,
carbolic cresylic and their homologues whether the said acids are derived from tars
produced in the manufacture of coal gas or by condensation of the volatile matters
given off in the manufacture of coke in ovens or otherwise and which said
gelatinized preparation of the tar acids is more convenient for package and
carriage and less liable to cause accidental or other injury to persons using or
employing the said tar acids without interfering materially with their concentrated
state or effective strength as disinfectants or germicides.
To effect this object I dissolve in the said liquid mixtures of the tar acids named
or their homologues one or any of the waxes enumerated below-
Bees wax
Carnauba wax
Ceresine wax
Paraffin wax
Chinese or insect wax
Palm tree wax
and the proportions I find most convenient for a temperate climate are 97 parts
of liquid tar acid and 24 parts of wax using a little heat to facilitate solution the
jelly or paste being formed on cooling. These proportions I vary necessarily
according to the climate in which the preparation is intended to be used and cannot
therefore bind myself to them.
A. tropical climate would require an increase in the proportion of wax dissolved
in the tar acids while a lesser proportion would suffice for the purpose of fixing or
gelatinizing them in a colder one.
As already specified it is immaterial for the purposes of my invention whether
the tar acids have been produced from the tars obtained in the manufacture of coal
gas or by the condensation of the volatile products evolved in the manufacture of
coke or otherwise.
The admixture of wax with and the preparation by this means of such acids in
the form of jelly or paste as described I believe to be novel and to afford increased
facilities for package and carriage as well as to obviate almost entirely any liability
to accidental or other injury to the public generally when employing them for
disinfecting purposes.
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 :-
The new or improved preparation of the concentrated liquid mixtures of the
nhenol series of tor acids namely carholio prosulio and their homalacuse in the

page_text: form of a jelly or paste obtained by the combination with or solution therein of
one or any of the varieties of wax named herein substantially as set forth.
Dated this 18th day of June 1895.
