I, CHARLES DENTON ABEL of N° 28 Southampton Buildings, Chancery Lane, in
the County of Middlesex, Consulting Engineer and Patent Agent do hereby declare
the nature of this invention to be as follows:-
In the Specification to Glaser's Patent N° 4992 of 1882, are described processes
for the production of a body termed "Lanolin," that is to say, the combination of"
neutral fatty matter from wool with water, or the neutral fatty matter itself, in
which processes a separation of the raw Lanolin was effected by centrifugal action
upon either the waste waters from the wool washing establishments, in which the
wool fat has been formed into an emulsion by means of soap, soda or other alkalies,
or upon the emulsion liquid produced from the wool fat of commerce by means of
soap, soda, or other alkalies, rendered acid by fat acids or other acids.
"
The present improvements have firstly for their object to obtain the "Lanolin
or the neutral wool fat without employment of centrifugal action. If the emulsion
liquid is allowed to stand for a certain time at ordinary temperature, a separation
will of itself take place by subsidence without any other addition, forming an
upper layer containing the raw Lanolin and a lower layer containing mainly the
soap lye, and in some cases an intermediate layer between the two.
The upper,
creamy layer is removed from the lower layer and is either directly utilised as raw
Lanolin, as is possible for some purposes, or it is treated in the manner described in
the Specification to Patent N° 4992 of 1882.
Instead of causing the material to separate by subsidence, as described, the
separation may be more quickly effected by diluting the emulsion liquid. This
dilution is best effected by causing a strong and copious jet of water to flow into
the emulsion liquid, its effect being to prevent the wool fat-Lanolin-contained
therein from remaining in an emulsion-like condition, causing it to rise to the
surface in solid flakes and cheese-like masses. A stirring action may be carried on
by mechanical means at the same time as the introduction of the water.
flakey masses thus obtained are removed from the liquid by suitable scooping
The

page_text: arrangements such as sieves, collanders &c and are then kneaded with cold water
for the removal of the adhering soap solution.
The operations of subsidence and of dilution may both be employed by carrying
thêm out consecutively.
The separation may be still easier effected if the saponaceous matter contained
in the emulsion be converted into fat-acid combinations of the alkaline earths, or
of the heavy metals, which is effected by adding salts, soluble in water, of the
alkaline earths or heavy metals. Although by this method a compound of Lanolin
with fat-acid salts is obtained, from which the former cannot be readily separated,
and thus the preparation of a pure product by this means is rendered difficult, yet
a Lanolin compound is thus obtained that is sufficiently pure for cosmetics and
other similar purposes.
In preparing the emulsion liquid from the wool fat of commerce according to
Patent No 4992 of 1882 an addition of soap or alkalies is employed, carbonate of
soda and hydrate of soda being specially mentioned, which materials may obviously
be replaced by carbonate of potass, hydrate of potass, ammonia, and carbonate of
ammonia. Further experiments have shown that the formation of the emulsion
liquid from the wool fat of commerce can also be effected by the addition of amine
bases, or bi-carbonates, silicates and borates of the alkalies, also of vegetable
'emulsion materials, such as saponine and all drugs containing saponine, such as
Saponanaria officinalis, Cortex quillajae Chinensis, Gypsophila Struthio, Agros-
temmis Githago, Polygala Amara &c or of animal emulsion materials such as
Pancreatine &c.

from Compounds Containing Wool Fat.
I, CHARLES DENTON ABEL of N° 28 Southampton Buildings, Chancery Lane in
the County of Middlesex, Consulting. Engineer and Patent Agent, 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:-
In the Specification to Glaser's Patent No 4992 of 1882, are described processes
for the production of a body termed "Lanolin," that is to say, the combination of
neutral fatty matter from wool with water, or the neutral fatty matter itself, in
which processes a separation of the raw Lanolin was effected by centrifugal action
upon either the waste-waters from wool washing establishments in which the wool
fat has been formed into an emulsion by means of soap, soda or other alkalies, or
upon the emulsion liquid produced from the wool fat of commerce by means of
soap, soda or other alkalies, rendered acid by fat acids or other acids.
The present improvements have firstly for their object to obtain the "Lanolin"

soda and hydrate of soda being specially mentioned, which materials may obviously
be replaced by carbonate of potass, hydrate of potass, ammonia, and carbonate of

liquid from the wool fat of commerce can also be effected by the addition of amine
bases or bicarbonates, silicates and borates of the alkalies, also of vegetable emulsion
materials, such as saponine and all drugs containing saponine, such as saponanaria
officinalis, cortex quillajae chinensis, gypsophila struthio, agrostemmis, githago,
polygala amara, &c or of animal emulsion materials such as pancreatine &c.
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:
1. In the process for the preparation of raw Lanolin from the waste liquors of
wool washing establishments or from the emulsion liquor produced from the wool
fat of commerce, the method of separating the raw Lanolin from the emulsion
liquid obtained as described in the specification to Patent N° 4992 of 1882 by
allowing the emulsion liquid to stand until the raw Lanolin contained therein
forms an upper layer by subsidence of the other constituents, substantially as
herein described.
2. In the process for the preparation of raw Lanolin from the waste liquors of
wool washing establishments or from the liquor produced from the wool fat of
commerce, the method of separating the raw Lanolin from the emulsion liquid
obtained as described in the specification to Patent N° 4992 of 1882 by diluting
the emulsion liquid with water, whereby the Lanolin is made to separate in
flocculent form, substantially as herein described.
3. In the process for the preparation of raw Lanolin from the waste liquors of
wool washing establishments or from the liquor produced from the wool fat of
commerce, the method of separating the raw Lanolin from the emulsion liquid
obtained as described in the specification to Patent N° 4992 of 1882, by first
allowing the said liquid to stand for a time so as to separate into layers of different
specific gravity, and then diluting the liquid with water with or without conversion
of the saponaceous matter contained in the liquid into fat-acid compounds of the
alkaline earths or of the heavy metals by the addition of salts, soluble in water of
the alkaline earths or of the heavy metals, substantially as herein described.
4. In the production of emulsion liquid from the wool fat of commerce such as
is described in the specification to Patent No 4992 of 1882 the use, in lieu of the
alkalies mentioned in the said specification, of amine bases, or bicarbonates,
silicates, or borates of the alkalies or vegetable emulsion materials such as saponine
and all drugs containing saponine such as saponanaria officinalis, cortex quillajae
chinensis, gypsophila struthio agrostemmis, githago polygala amara, &c or animal
emulsion materials such as pancreatine and the like, substantially as herein
described.
