MANUFACTURE OF RESIN SOAP
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
I, JOHN IMRAY of No 28 Southampton Buildings, Chancery Lane in the County
of Middlesex, Consulting Engineer and Patent Agent do hereby declare the
nature of the said invention for MANUFACTURE OF RESIN SOAP" (Communicated
by H. J. E. Hennebutte) to be as follows:-
This invention relates to the manufacture of resin soap almost colourless, without
causticity, freely soluble even in sea water, and having a slight agreable odour.
Resin pulverised when treated in the first place with dilute acid, preferably
sulphurous or sulphuric acid, is, after drainage, in condition to be freely attacked
by alkali producing a good soap. But if, instead of acid, a weak solution of
sulphate of alumina be employed, and the resin after treatment therewith be
carefully saponified, a soap liquor is produced almost colourless and having a
pleasant odour. This liquor cooled with a little agitation, produces white curd
which is readily separated from the excess of liquid. An excellent soap may be
made by mixing a little fat soap with this curd, or by adding to the curd a small
quantity of silicate of soda and slightly heating.
Dated this 19th day of March 1884.

page_text: I, JOHN IMRAY, of No 28' Southampton Buildings, Charicory Lano in the County
of Middlesex Consulting Engineer and Patent Agent do hereby declare the nature
of my invention for "MANUFACTURE OF RESIN SOAP" (Communicated by E. J.
E. Hennebutte) 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 the manufacturō'of resin soap almost colourless, without
causticity, freely soluble even in sea water, and having a slight agreable odour.
Rosin pulverisod, when treated in the first place with dilute acid, preferably
sulphurous or sulphuric acid, is, after drainage in condition to be freely attacked
by alkali, producing a good soap. But if, instead of acid, a weak solution of
sulphate of alumina be employed, and the resin after treatment therewith be
carefully saponified, a soap liquor is produced, almost colourless, and having a
pleasant odour. This liquor cooled with a little agitation, produces white curd
which is readily separated from the excess of liquid.
If a small quantity of fat soap be added to this curd, a soap of the best quality
will be produced. Also, without the addition of fat soap, a white and very firm
resin soap will be obtained by slightly heating the curd together with a small
quantity of silicate of soda.
By the above described means a white product is economically obtained which
is neither fatty nor adherent, nor caustic, and which is freely soluble and has an
agreeable odour.
Having now particularly described and ascertained the naturo of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
The above described improved manufacture of resin soap, wherein the resinous
matter is treated before alkaline saponifaction, with dilute sulphurous or sulphuric
acid, or with sulphato of alumina, the said soap being used either by itself or with
an admixture of fat soap or of silicate of soda.
This Oth day of December 1884.
