PROVISIONAL SPECIFICATION.
An Improved Soap Powder and the Method or Means of
Manufacturing the same.
I, JOHN MILLS MCCALLUM, of the Caledonia Soap Works, Paisley, in the County of
Renfrew, North Britain, Soap Manufacturer, do hereby declare the nature of this
invention to be as follows:—
This Invention relates to an improved Soap Powder and consists in the incorpora-
tion of paraffin oil along with the other ingredients used in the manufacture of soap
powder.
In accordance with my Invention I manufacture the soap powder by boiling the
ordinary soap along with the alkali which is recovered from the inanufacture of caustic
lye; after cooling 1 add the paraffin oil with or without salts and in this state I put
the substance through a process of grinding whereby it is made suitable for being put
up in packets or cakes ready for the market.
The soap powder produced in accordance with my said Invention has greater
cleansing power than that of soap powders as at present in use.

1, JOHN MILLS MCCALLUM, of the Caledonia Soap Works, Paisley, in the County of
Renfrew, North Britain, 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 :-
My said Invention relates to an improved Soap Powder and consists in the incor-
poration of paraffin oil along with the other ingredients used in the manufacture of
soap powder, my process of manufacture being as follows.
I boil the ordinary soap along with the Alkali which is recovered from the manu-
facture of Caustic lyc. About fifteen minutes after the soap as above has come to the
boil, and is in a pasty condition, I add paraffin oil, with or without salts, in the
proportion, preferably, of about nine per cent. to the whole, that is to say to the soap,
salts, and alkali combined.
After the addition of the paraffin oil, the mixture is poured into wooden trays, or it
may be equivalent of such, as the drying process, and is then raked about till the soap
is brought into a lumpy condition. After the soap has become thoroughly dried it is
put through any suitable grinding machine, and is finally produced as a fine powder,
suitable for being put up into packets or in the form suitable for the consumer.
The soap powder produced in accordance with my said invention, has greater
cleansing power than that of any soap powders as at present in use.
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
1st. In the manufacture of a soap powder for laundry and other purposes the
employment of paraffin oil incorporated therewith, substantially as hereinbefore
described.
2nd. In the manufacture of a soap powder, the combination of processes substantially
as described for the purpose of incorporating paraffin oil.
