We ANDREW MACALISTER 414 Duke Street, Glasgow in the County of Lanark
Chemist and WILLIAM STEWART, 175 St. Vincent Street, Glasgow aforesaid Writer
do hereby declare the nature of this invention to be as follows:-
The preparation of a combination of iodine with olive, castor or any other vegetable
oils for the purpose of external application to the human or animal skin or as a
medicine for internal use. The oil is in the first place treated with strong sulphuric
acid. It is then allowed to lie from 12 to 24 hours, then washed twice or thrice with
water or a strong saline solution preferably of common salt in water at about
20° Twaddle and then after brisk agitation for about half an hour the oil is allowed to
settle for from 24 to 36 hours by which time the oil has come to the surface & it is
thereafter separated from the saline liquor beneath it in any convenient way. After
this a solution of caustic ammonia potash or soda in water is added till the oil is
slightly alkaline. Then there is added a solution of iodine in alcohol or other solvent
of such strength & quantity as may be desired when it will be found that the iodine
combines with the oil and forms a clear iodised oil suitable for the purposes before
mentioned.

page_text: Mrs. HELENA GARTH NIXON or MACALISTER, residing at 19 Reidvale Street
Glasgow Executrix of the deceased Andrew Macalister, Chemist Glasgow and
WILLIAM STEWART, 175, St. Vincent Street, Glasgow aforesaid Writer, 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:-
The said invention has for its object the preparation of a combination of iodine with
olive, castor or any other vegetable oils for the purpose of external application to the
human or animal skin or as a medicine for internal use. Hitherto it has not been
found practicable to form a combination of iodine or a solution of iodine with oil as the
iodine or iodine solution invariably separates from the oil. This difficulty has been got
over by the said invention. The mode in which this combination is effected by the
said invention is as follows. The oil is in the first place treated with about twenty
per cent. of its weight of strong sulphuric acid-it is then allowed to lie for from
twelve to twenty four hours then washed twice or thrice with water or a strong saline
solution preferably of common salt in water at about 20° Twaddle and then, after brisk
agitation for about half an hour, the oil is allowed to settle for from twenty four to
thirty six hours, by which time the oil has come to the surface. It is thereafter
separated from the saline liquor or water beneath it in any convenient way-after
this a solution of an alkali preferably ammonia or caustic potash or soda in water at
about 12° Twaddle is then added with constant stirring till the oil is neutral or only
slightly acid and quite clear and thereafter a small quantity more of the alkali solution
is again added to prevent the oil from becoming clouded. Thereafter there is added
to the oil so prepared a solution of iodine in alcohol or other solvent of such strength
and quantity as may be desired when it will be found that the iodine combines with
the oil and forms a clear iodized oil suitable for the purposes before mentioned.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed we declare that what we claim to be
novel and original in the said invention is-
The combining of the said solution of iodine with the oil in the mode before
mentioned so as to prevent the iodine or iodine solution separating from the oil.
