PROVISIONAL SPECIFICATION.
A New or Improved Detergent or Tanning Substance.
I, PETER CAMERON DOUGLAS CASTLE of 7 Temple Street, Liverpool in the
County of Lancaster, Secretary and Manager of The Gum Tragasol Supply Co.
do hereby declare the nature of this invention to be as follows:-
This invention relates to a new or improved detergent or soap extracted from
the husks of the nut of the "soap berry" (Sapindus trifoliatus L.). I find that by
steeping the husks of this nut, preferably in stone-ware vessels in boiling water
which is kept up to a temperature of 180 to 190° F. and macerating for seven hours
all the detergent substance is held in suspension in the water.
The quantity of water which I have, as yet, found to produce the best results,
is one gallon to every pound of husk.
After seven hours maceration the whole must be pressed through a strong coarse
silk and then placed in evaporating pans taking care that the temperature does
not get much over 190° F., the best result being obtained when the solution is
kept at 180 to 190°. The result will be a thick sticky resinous substance which
becomes as hard as beeswax at any temperature below 60°, is readily melted with
either hot or cold water forming a powerful lather having much greater cleansing
properties than soap and yet free from free mineral alkali, and can be used either
alone or in combination with any other saponified substance with which it freely
mixes or dissolves. It can also be used for tanning and dressing any kind of
animals' skins and such like purposes.

all the detergent substance is held in suspension in the water.
The quantity of water which I have, as yet, found to produce the best results,
is one gallon to every pound of busk.
After seven hours maceration, the whole must be pressed through a strong coarse
silk, and then placed in evaporating pans taking care that the temperature does

claim is :-
The new or improved detergent or tanning substance formed by extracting the
soluble matter of the husks of the soap berry (Sapindus trifoliatus L.) and used
either alone or in combination with other soaps substantially as described.
