COMPLETE SPECIFICATION.
An Improved Washing Material, and Process for Making the same.
I, GEORG REZEK of 10 Ladenburg Gasse, Vienna in the Empire of Austria,
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 improved washing material forms a valuable substitute for soft soap, and is
especially suitable for technical and also household purposes and may also be used
as a hand soap replacing cakes of soap.
The method of making the same is considerably quicker and easier than the
usual methods of making the ordinary soft soaps. As animal fat is entirely
excluded in its production, the manufacture is not coupled with nuisances, such as
bad smells, pollution of water, etcetera, as in the present manufacture of soap.
Finally, the process of manufacture effects a considerable saving of material
and apparatus and also of labour, as no preparation of a lye nor boiling of the soap
takes place.
These advantages are produced in the simplest manner by resin, more particularly
fir tree resin, being mechanically mixed with alkali carbonate, preferably with the
addition of water.
The resin may either be mixed with the alkali carbonates in a dry condition and
the mass then kneaded and rolled for a long time with a sufficient quantity of warm
or cold water until it has become homogeneous, or the two initial materials may be
stirred up in succession in water.
In the practical carrying out of the process I take to 125 kilogrammes of
ammonia soda and 60 kilogrammes of fir resin about 120 kilogrammes of water.
The dry and pulverised ammonia soda is thoroughly mixed with the fir resin, which
is equally ground and pulverised, and the mixture is then stirred up with the above
mentioned quantity of cold or warm water.
Or, 125 kilogrammes of ground ammonia soda may be first placed in 120 kilo-
grammes of water, and then 60 kilogrammes of pulverised fir resin be added thereto.
After the whole has been thoroughly mixed, the substances, after long continued
kneading or rolling, will become a more or less soft saponaceous substance.
In order to obtain given properties, larger or smaller quantities of glycerine,
benzine, fats, oils, perfumes and colours may be added according to requirements.
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. A washing material consisting of a mixture of alkali carbonates and resin.
2. A process for making the herein before described washing material, consisting
in mixing the dry pulverised materials (alkali carbonates and resin), then adding
the necessary quantity of water, and finally kneading and rolling the mixture until
the consistency of soft soap is imparted to the mass substantially as hereinbefore
set forth.
3. A modification of the process for making the hereinbefore described improved
washing material, consisting in conveying a given quantity of pulverised alkali
carbonate into warm or cold water, then adding the resin also pulverised and finally

substantially as herein before set forth.
