I, PETER BRENTINI of 112 Fleet Street in the City of London, Merchant, do.
hereby declare the nature of my invention for "AN IMPROVED MANUFACTURE
OF SAPONACEOUS MATERIAL FOR WASHING PURPOSES to be as follows:-
According to my invention I prepare a saponaceous material for washing
purposes as follows:
About 10 lbs of Fucus are placed in about 50 lbs of cold water and heated for
6 hours, producing a colored liquor, which is then strained.
About 8 lbs of castor oil or cocoa nut oil are heated in a vessel together with
about 3 lbs of Colophone until melted, whereupon about 2 lbs of caustic soda
dissolved in about 4 lbs of water are added and the whole is boiled until it forms
a saponaceous paste. To this the above mentioned 50 lbs of Fucus extract are then
added and the whole is heated to near boiling point, after which 50 lbs of refined
alkali are added thereto, and after being well boiled, the mass is mixed in a vessel
with about 1 oz of mirbone or other scent, and stirred rapidly for about 40 minutes.
When cold, a yellowish solid saponaceous material is formed which is of great
efficacy for washing purposes, as a substitute for ordinary soap, such as for washing
linen to which it imparts great whiteness.

page_text: Purposes.
I, PETER BRENTINI of 112 Fleet Street in the City of London, Merchant 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:-
According to my invention I prepare a saponaceous material for washing 5
purposes as follows.
To produce 1 cwt of the saponaceous material or lessive, I take the following
ingredients
1 of Castor; Cocoa, or Palm Oil 6 lbs
2 Fucus Seaweed or Soapberry 4 lbs
3
4
5
6
"
"
"
"
"
Silicate of Soda of 24 overproof 6 lbs.
Resin or Colophonium powdered 6 lbs
Refined Alkali 48 overproof 50 lbs
Oil of Mirbane 4 ozs.
Of these ingredients, the Fucus or Soapberry is first allowed to simmer in about 1
5 gallons of water for about 6 hours, after which the liquid is strained off. The
ingredients Nos 1 and 3 are then heated together in a separate vessel and when they
become amalgamated, the above decoction is mixed with them and the whole is
heated to boiling point, whereupon ingredient No 4 is added and the mixture is
allowed to simmer until it becomes a kind of soapy paste. The mass having been
thoroughly incorporated, ingredient No 5 is added and thoroughly stirred in. This
compound is then passed through a metal strainer, after which ingredient N° 6 is
added and thoroughly stirred in for about 40 minutes, whereupon the compound
is allowed to cool and solidify.
Although I prefer to use the materials in the proportions indicated, I do not
limit myself to these, as they may be variously modified according to circum-
stances; thus if a more energetic action is required, the ingredients may be
increased so as to obtain a stronger compound, and in some cases other materials
such as carbonate of Potash and Calx Chlorinat may be added in small quantities.
The lessive or detergent produced as above described possesses the advantages,
among others, over ordinary soap or soda, that the expenditure of washing
material and of labor is less, no scrubbing being usually required, while the linen
silk and flannel goods so treated will last longer and will have a better color and a
pleasant odour imparted to them. Not being in any way poisonous or detrimental
to the hands or eyes, it may be used with perfect safety. It is also applicable with
advantage for scrubbing floors, pictures and picture frames, and the waste water
will tend to cleanse and purify and will not stop up the drains.
In using the lessive, the dirty linen &c is put in a tub with sufficient cold water
to make it thoroughly damp, The lessive is then dissolved in boiling water in the
copper to the extent of about one pound to every 5 gallons of water, and the linen

page_text: being introduced, it is boiled for a few minutes, after which it is gently rubbed in
the same water, and is finally rinsed in clean water.
For silk, flannel and colored articles a small quantity of the lessive is dissolved in
boiling water and used warm, the articles being simply soaked and slightly rubbed
in the solution, and afterwards rinsed in cold water. The water should not be
used too warm for flannel. No detriment to the material operated upon will
accrue if an excessive quantity of the lessive should by accident be introduced to
the solution.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is :-
A saponaceous or detergent compound or lessive, for washing purposes consisting
of Castor or Cocoanut or Palm oil, Fucus or Soapberry, Silicate of Soda Resin or
Colophone, Refined Alkali and Oil of Mirbane, prepared substantially, as herein
described.
