Method of Producing Highly Concentrated Fat Solutions of Fragrant
Substances.
I, HEINRICH MACK, of 21 Kohlgasse, of Ulm on the Danube, Manufacturer, do
hereby declare the nature of this invention, and in what manner the same is to bo
performed, to be particularly described and ascertained in and by the following
statement:
It has repeatedly been tried of late to produce washing-means in which soap
[on account of its scouring influence upon the skin, and of its smell impairing
the odour of the fragrant substance used for perfuming it] was entirely dispensed
with. As to preventing the skin from being scoured, this effect has been attained
by some pulverous materials as starch powder (possibly tale) and also drugs (as
f.i. powdered violet root) [that preferably were compressed so as to form a handy,
piece], but then there arose some difficulties in perfuming the compressed pieces
of the pulverous materials as starch powder (possibly tale), and also drugs (as
f.i., powdered violet root), because the odours of the fragrant substances got soon
lost in consequence of these substances being dissolved in alcohol, and of the pieces
of the pulverous materials being comparatively loose in spite of these materials
being compressed.
In view of the fact that the odours of fragrant substances are preserved far
better in fat than in alcohol trials were made to perfume the pieces of pulverous
materials afore mentioned by means of fats that had no smell of their own [either
animal vegetable or mineral] and were rendered odourous by being macerated
with suitable flowers. It was found, however, that to properly perfume the
pieces of the pulverous materials with such a fat so great a quantity of this latter
had to be added to said materials that the pieces dissolved with difficulty in water
and made the skin greasy instead of cleaning it.
The object of my present invention is to do away with all theso drawbacks,
and I attain that purpose by manufacturing the solutions of the fragrant sub-
stances in a manner as hereinafter described.
A concentrated alcoholic solution of the respective fragrant substance [which
solution I may either prepare myself or buy it ready-made] is diluted with water; a
molten scent-less fat or vaseline [either animal vegetable or mineral] is then added
to said solution and the mixture is vehemently shaked [preferably by means of a
suitable apparatus, and with the application of heat] until the colour Iras passed
over from the solution to the fat. Even with a concentrated solution said passing
over of the odour occurs completely which is due to the solution having been
mixed with water. I may thus produce a highly odorous fat of which very small
quantities only need be admixed to the pulverous materials to properly perfume
these latter. Thus, in consequence of said quantities of the odorous fat being
but very small the dissolvability of the pulverous materials is not in the least
impaired, and in consequence of the odour being bound to fat the odour remains
with the pulverous material until this latter has been completely used up.

page_text: The fragrant substances employed may be either natural ones or artificial ones,
or a mixture of one with the other.
To 100 gr. vaseline I add 100 gr. of alcoholic solutions of the respective fragrant
substances, this solution is operated with, as herein before described until the
odour of the fragrant substances has passed over from the solution to the fat,
I then add further proportions of the alcoholic perfumed solutions in quantities
of 100 gr. at a time and by each such addition of the perfumo I effect the trans-
ference of the odour as herein before described, and repeat these proportions until
1 Ko. of the alcoholic fragrant solutions has been used up or employed in the
transference of the perfume of the same to the fat that is to say, to the first
mentioned 100 gr. of vaseline.
With regard to the proportions of the substances employed the following is an
6 parts of perfumed vaseline.
The above proportions are, as indicated, only intended as examples and I desire
it to be understood that I do not bind myself to such proportions, but reserve the
right of varying the same in accordance with the strength I desire to give to the
finished product.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what I
claim îs:-
1. The method of producing highly concentrated fat solutions of fragraut sub-
stances, characterised by dissolving the latter in alcohol, diluting the solution
with water, adding a scentless fat to the diluted solution, shaking the mixture
so as to cause the fragrant stuff to pass over to said fat, and separating the latter
from the liquor, as set forth.
2. The method of producing highly concentrated fat solutions of fragrant sub-
stances, characterised by dissolving the latter in alcohol, diluting. the solution
with water, adding molten vaseline in the diluted solution, shaking the mixture
so as to cause the fragrant stuff to pass over to the vaseline, and separating the
latter from the liquor, as set forth.
3. The method of producing highly concentrated fat solutions of fragrant sub-
stances, and perfuming pulverous washing-and toilet-means with the fat solu-
tion, consisting in dissolving the fragrant substance in alcohol, diluting the
solution with water, adding a scent-less fat to the diluted solution, shaking the
mixture so as to cause the fragrant stuff to pass over to said fat, separating the
latter from the liquor, and adding it to the respective pulverous stuff whilst
rubbing and agitating the latter, as set forth.
