I, GUILLAUME STECKEN, of Ostend, in the Kingdom of Belgium, Soap
Manufacturer, do hereby declare the nature of this invention to be as follows:-
My invention relates to the manufacture of soap.
Soap made according to my said invention gives by the washing operation a
cream tint to the fabrics.
I may also manufacture this soap so as to obtain other tints, for instance light
blue, thus dispensing with the blueing of the washed fabrics.
This soap is composed of the following materials:
(1.) 10 per cent. of cocoa-nut oil, palm oil, olein, olive oil, beef tallow or any
other animal or vegetable fatty material which is saponifiable.
(2.) 10 per cent. of caustic soda in 40 litres of water.
Let boil for about an hour until the saponification of these two materials is
complete.
(3.) 10 to 15 per cent. of colophony. Let boil for a quarter of an hour.
(4.) 2 per cent. of sea salt dissolved in 4 litres of water.
(5.) 2 per cent. of sodium sulphate dissolved in 4 litres of water.
Mix these two materials together and then use this mixture in the saponification
of the first three materials.
(6.)th per thousand of yellow chrysaniline or any other yellow colour capable
of withstanding the action of caustic soda, which is necessary for the manufacture
of my improved soap, and which like the chrysaniline gives a strong yellow tint
upon vegetable materials.
(7.)th per thousand of rosaniline or any other rose-coloured or red product
which accords with the chrysaniline and, like the latter, can withstand the action
of caustic soda and gives a strong rose-coloured tint upon vegetable materials.
For obtaining a variation in the shades of my improved soap I add or
1 per thousand of benzo blue which gives with white soap a blue tint, but which
when mixed with the before-mentioned product gives a more greenish yellow.
In like manner azo violet, which gives with white soap a lilac-coloured or violet
tint, gives when mixed with my improved product a more greenish or violet yellow;
Prussian blue with white soap gives a bluish white or azure tint, and when mixed
with my aforesaid product gives a more vivid greyish yellow.
By drying and grating this soap I obtain soap powder. For obtaining it in the
liquid or soft state I replace the caustic soda by potash.

page_text: I, GUILLAUME STECKEN, of Ostend, in the Kingdom of Belgium, 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 invention relates to the manufacture of soap.
Soap made according to my said invention gives, by the washing operation, a
permanent tint to the washed fabrics.
This soap is composed of the following materials :-
That is to say, 10 kilogrammes of cocoa-nut oil, palm oil, olein, olive oil, beef
tallow, or any other animal or vegetable fatty material which is saponifiable.
10 kilogrammes of caustic soda dissolved in 40 litres of water.
These materials are allowed to boil for about an hour until saponification is
complete, and to them may be added gradually
10 to 15 kilogrammes of powdered colophony (resin), the whole being well stirred
together and allowed to boil for a quarter of an hour.
The resin is employed to increase the bulk and cheapen cost of production, as is
now well known, and is not necessary for the purposes of my invention.
I next take a material which will serve to neutralize any excess of alkali in the
saponified mass, such as sea salt, as is well known, two kilogrammes being dissolved
in 4 litres of water, and also a material which will act as a mordant, such, for
instance, as sodium sulphate, 2 kilogranimes of which are dissolved in 4 litres of
water.
I mix them together, and then add this mixture to the soap while still in the
semi-fluid state.
I next take the coloring matter, which may be yellow chrysaniline, or any other
suitable yellow dye capable of withstanding the action of the caustic soda which
has been used in the manufacture of my improved soap, in the proportion of about
one gramme of dye to one kilogramme of soap, and I stir it well into the semi-fluid
soap, which is then allowed to cool and harden, and is made up into cakes or bars
for the market, in the usual way.
If a red soap be required, I take about one half gramme of dye per kilogramme
of soap, say, rosaniline, or any other suitable rose colored or red product which
will also withstand the action of the caustic soda, and stir it well into the mass of
soap.
If the colouring matter is in a solid form, it will be dissolved in water before
adding it to the soap.
For obtaining a blue shade in my improved soap, I may take from 5 to
10 grammes per kilogramme of soap of benzo blue dye, which gives with white
soap a blue tint, but which, when mixed with the before mentioned yellow product,
gives a greenish yellow.
In like manner I may use in varying proportions azo violet which gives with
white soap a lilac colored or violet tint, or when mixed with my yellow product a
greenish or violet yellow. Prussian blue with white soap gives a light blue or
azure tint, and when mixed with my aforesaid yellow product a more vivid greenish
yellow.
Of course various other tints may be obtained by mixing two fundamental colors,
such as red and yellow, to make orange, or red and blue to make purple, and so on.
It will be obvious that the proportions given above are by way of illustration
only, and can be varied without departing from the nature of my invention.
I may also use any of the so-called "aniline" colors which resist soda, however
produced, for the purposes of my invention, the essential object of which is, to

page_text: allow of the permanent production of all tints upon cotton and silk by one single
operation, which has not heretofore been obtained.
I may also add any suitable chemical substance, mineral, vegetable, or animal,
in place of sea salt, sulphate of soda, or resin, for similar purposes, without in any
way deteriorating or altering the soap, for instance, in some cases, oxide of zinc
may be used as a mordant.
My soap
thus composed may serve for permanently tinting cotton, silk and wool.
By drying and grating this soap I obtain soap powder; and for obtaining a soft
soap, I replace the caustic soda by potash, as is well understood.
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 :-
An improved soap for imparting, by the washing operation, a permanent cream,
or any other tint, to the stuff or material treated, the soap being composed as
hereinbefore described.
