COMPLETE SPECIFICATION.
An Improved Soap, and Process of Manufacture therefor.
I, WILLIAM SPARKS THOMSON, of 112, Fore Street, London, E.C., Manu-
facturer, 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 and process of manufacturing the
same and it has for its object the production of an ammonia soap, the ammonia being
incorporated therewith in such a manner as to allow it to blend firstly with the
lavender or other essential oils used for perfuming purposes and secondly with
the soap itself without combining with and injuring the fatty materials contained
therein which would be destructive to the soap, and also to mix the ammonia there-
with in a manner so as to prevent the formation of bubbles or blisters therein after
milling, permitting the ammonia to escape from the composition.
In carrying the invention into effect the soap after being prepared in the usual
way for milling is milled and upon the completion of the milling
the colouring matter, or superfatting or other ingredients that may
be desired are added. The whole is then again milled and liquid ammonia
combined with spirits of wine is rapidly added to the soap, whilst in the condition
arrived at after the two millings, a perfuming compound composed of essential
oils such as lavender, geranium, peppermint, or patchouli combined with liquid
ammonia and rectified spirits of wine is added immediately and rapidly after the
first addition of ammonia. The whole of this compound must be prepared at
least 48 hours before being added to the soap which after such addition is
immediately passed through the mill and is finished in the usual manner.
The actual process and proportion of parts is as follows: To the soap after
being milled, the colouring matter, or other ingredients, is added and the soap
passed through the mill and liquid ammonia in the following proportion is added:-
To 84 pounds of soap 2 oz. of liquid ammonia carefully mixed with 4 ozs. of
rectified spirits of wine and worked quickly into the soap whilst in the condition
arrived at after the two millings; next is added quickly a compound" composed
of 2 ozs. of ammonia mixed with 4 ozs. of rectified spirits of wine blended with
26 ozs. of mixed essential oils, the whole being in proportion of 32 ozs. of " com-
pound" to 84 lbs. of soap. The whole of the compound thus made must be mixed
at least 48 hours prior to using.

Although I have stated the total amount of ammonia as 4 oz. to 84 lbs. of soap
I do not wish to limit myself to such proportion as I may vary this to suit the
requirements of the consumer.
After working the compound into the soap it is milled a third time and may
then be finished in the usual manner.

invention, and in what manner the same is to be performed, I declare that what
I claim is:-
1. The improved soap substantially as herein described.
2. In the manufacture of a soap of the kind herein described the method
employed for mixing and combining the ingredients in the proportions stated,
substantially as herein described
