COMPLETE SPECIFICATION..
A New or Improved Soap Extract, and a Process for Manufacturing
the same.
I, AUGUST LUHN, of Rittershausen, Barmen, in the Empire of Germany,
Soap Manufacturer, 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 :-
"
This invention relates to an improved "soap extract' and to a process for
manufacturing the same.
In preparing a soap lye it is necessary to reduce the hard soap (in the form of
cakes or bars) into small pieces, which process is very inconvenient. To save this
operation soap powders are largely used. In reducing soap to powder it is
necessary to thoroughly dry it and certain soaps lose a great deal of their washing
or cleansing power by this treatment. It will thus be seen that with such soaps it
is very necessary to avoid the drying process and to accomplish this is the object
of this invention.
It is already well-known that sal-ammoniac and turpentine added to a soap lye
in certain proportions produce a powerful cleansing effect. For making the
extract according to the present invention a white, chemically pure moulded soap
is preferably used with which is incorporated the two hereinbefore mentioned.
substances in such a manner that every particle of the soap absorbs as much as
possible of these substances.
In consequence of the oil of turpentine and the ammonia which this soap contains
it is impossible to reduce it to a powder, and it is also absolutely necessary to
divide it in such a manner as to permit the soap retaining the greatest possible
amount of these two substances.
According to this invention 180 parts of soda are dissolved in 300 parts of.
boiling water. Into this solution is allowed to melt 200 parts of pure soap having
a base of turpentine and ammonia to which is added 200 to 300 parts of dried sifted
neutral soap.
The soap thus obtained is shredded or divided into threads or filaments and
mixed by continual agitation with a pulverised neutral soap in the proportion
of 100 parts of the former to 200 parts of the latter, 3% of caustic ammonia being
added thereto.
The soap extract made according to this invention is well adapted for its purpose
and can be used as easily and conveniently as any of the numerous "soap
extracts at present on the market, while it has the merit of cheapness and
chemical purity.
"
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 :-
(1.) The improved process for manufacturing a washing or soap extract,
substantially as hereinbefore described.
(2.) The improved process for manufacturing a washing or soap extract
consisting in shredding or dividing the soap into threads, or filaments, the said soap
having a base of sal-ammoniac and turpentine and then mixing the said shreds or
ilaments of soap with a mass of powdered soap of such a kind as to prevent the
shreds or filaments from sticking to each other, as set forth.

described and claimed.
