PROVISIONAL SPECIFICATION.
Improvements in Liquid Disinfectant Soaps.
1, JAMES BRAND MCARTHUR, of 3 Parkfield, Newferry, in the County of
Chester, Chemist, do hereby declare the nature of this invention to be as
follows:-
According to this invention I produce in the following manner a liquid
disinfectant soap, which will not congeal at ordinary, or even low winter
temperatures.
The fatty material used may be saponified or distilled oleic acid, recovered
oleines, animal oil, castor oil, olive oil, ground nut oil, or any liquid vegetable oil,
or mixtures of any of these with or without rosin.
The alkali used is preferably caustic potash or carbonate of potash.
The quifying agent is carbolic or cresylic acids, or the mixture of these
commercially known as "carbolic acid and creosote, tar oils, naphthol, and
similar disinfectants; mineral oils may also be added for special purposes.
The following is an example of the process and proportions, which however may
be varied :-
86 parts of 77 per cent. caustic potash are dissolved in 250 parts of "carbolic
acid at about 200° F. and 355 parts of distilled oleic acid stirred in, the water
being adjusted to about 12 per cent.
A less convenient method is to saponify the fat with the alkali, and then dissolve
this soap in the "carbolic acid."
The resulting liquid soap is readily miscible with water and is suitable for
general household and sanitary cleansing, or as a sheep dip, insecticide in
gardens &c.
Dated this 20th day of November 1895.

Improvements in Liquid Disinfectant Soaps.
I, JAMES BRAND MCARTHUR, of 3 Parkfield, Newferry, in the County of
Chester, Chemist 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 :-
According to this invention I produce in the following manner a liquid
disinfectant soap, which will not congeal at ordinary, or even low, winter
temperatures.
The fatty material used may be saponified or distilled oleic acid, recovered
oleines, animal oil, castor oil, olive oil, ground nut oil, or any liquid vegetable
oil, or mixtures of any of these with or without rosin.
The alkali used is preferably caustic potash or carbonate of potash.
The liquifying agent is carbolic or cresylic acids, or the mixture of these
commercially known as "carb. lic acid," and creosote, tar oils, naphthol, and
similar disinfectants or mineral oils may also be added for special purposes.

The resulting liquid soap is readily miscible with water, and is suitable for
general household and sanitary cleansing, or as a sheep-dip, insecticide in
gardens &c.
Other forms of soap may also be made by saponifying fats or fatty acids by
means of carbolate or cresylate of potash or soda.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed 1 declare that what
I claim is
1. Rendering oleic soap fluid by carbolic or cresylic acids.
2. The production of such a soap by the combination of oleic acid, castor oil, and
similar fats, with a carbolate or cresylate.
3. The manufacture of liquid disinfectant soaps substantially as described.
Dated this Ninth day of May 1896.
