I, JOSEPH THOMAS POTTS, of Bromboro' Pool, in the County of Chester, do hereby
declare the nature of this invention to be as follows:-
According to this invention I produce in the following manner a liquid soap which
will not congeal at ordinary or even low winter temperatures.
The fatty material used is liquid cocoanut oil and rosin, together with one or more
of the following oils:-animal, neatsfoot, lard, fish, castor, cotton, olive, ground-nut,
rape, linseed, saponified or distilled oleic acid, recovered oleines or any vegetable
fatty oil.
The alkali used is preferably caustic potash and caustic soda, ammonia may also
be used.
The following is an example of the process and proportions, which however may be
varied-24 parts of liquid cocoanut oil, 4 parts cotton oil, and 12 parts of rosin are
melted together in a steam jacketted pan, and 3.14 parts of caustic soda and
4.39 parts of caustic potash dissolved in 52:47 parts of water added, and the mixture
stirred at intervals for about 2 hours. The temperature is then allowed to fall, and
any loss of water by evaporation made up by the addition of more water. For special
purposes the soap may be perfumed, or have a small quantity of mineral oil or
glycerine added.
The resulting liquid soap is readily miscible with hot or cold water, and is suitable
for all household purposes.

I, JOSEPH THOMAS POTTS, of Bromboro' Pool, in the County of Chester, 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 soap which
will not congeal at ordinary or even low winter temperatures.
The fatty material used is liquid cocoanut oil and rosin, together with one or more
of the following oils: animal, neatsfoot, lard, fish, castor, cotton, olive, ground-nut,
rape, linseed, saponified or distilled oleic acid, recovered oleines or any vegetable

any loss of water by evaporation made up by the addition of more water. For special
purposes the soap may be perfumed, or have a small quantity of mineral oil
turpentine or glycerine added.
The resulting liquid soap is readily miscible with hot or cold water, and is suitable
for all household purposes.
I am aware that liquid soaps have before been made from mixtures of two or more
fatty acids but the fluidity of these soaps has resulted from the presence of an excess
of water whereas whilst the individual soaps formed from the fatty acids I employ
would be solid or semi-solid my soap is liquid its fluidity resulting not from an excess
of water but from the blending of the fatty acids.
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. Liquid soaps whose fluidity results from the blending of two or more fatty acids
without the necessity for an excess of water.
2. Liquid soaps made from a mixture of two or more solid or semi-solid soaps.
3. Liquid soaps made from cocoa-nut oil, resin and one or more of the oils specified.
4. Liquid soaps substantially as described.
