Complete Specification Left, 1st June, 1900-Accepted, 7th July, 1900
I, AUGUST ZIMMERMANN, of 9 and 10, St. Mary at Hill, in the City of London,
Merchant, do hereby declare the nature of this invention to be as follows:-
Mixtures of the aromatic products with alcohol or spirits of wine for the produc-
tion of articles of perfumery such as Eau de Cologne, lavender water, essence of
violet and others derive their usefulness and appreciation of quality from the
intensity of the more or less energetic diffusion of the alcoholic vapours, carrying
the scenting body.
I have found that by combining such aromatic products with alcoholic liquids
and adding to these formaldehyd I obtain a considerably increased pungency of
these aromatic mixtures by throwing off a greater intensity of the body of the
perfume and I thus obtain articles of perfumery superior to those which are now
in use.

I, AUGUST ZIMMERMANN, of 9 and 10, St. Mary at fill, 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 hy
the following statement:-
Mixtures of aromatic products with alcohol or spirits of wine for the produc-
tion of articles of perfumery, such as Eau de Cologne, lavender extract, essence
of violet, and others owe their usefulness and appreciation of quality to the
intensity of the more or less energetic diffusion of the alcoholic vapours impreg-
nated or laden with the aromatic body.
I have found that by the addition of formaldehyde either in dissolved or gaseous
form to the combinations of such aromatic products with alcoholic liquids or the
like, I obtain a considerably increased pungency of these aromatic mixtures,
caused apparently by an increased intensity of volatilisation of the perfume body,
and I thus obtain articles of perfumery superior to those which have hitherto been
compounded.
My improved perfumes also possess the advantage when sprayed in sick-rooms
or elsewhere employed to counteract offensive or foetid odours, that the said
offensive or foetid odours are not merely covered or disguised by a stronger odour,

page_text: but are in most cases destroyed and rendered innocuous by the action of the for-
maldehyde in combining with the noxious gases to form inert compounds.
As an example of the manner in which my invention may be performed, I add
to one hundred parts of Eau de Cologne or to a like quantity of alcohol or spirits
of wine, preferably before admixture with the specific aromatic constituents of the
perfume, one part of a concentrated aqueous solution of formaldehyde. I do not
however confine myself to these proportions, which must necessarily vary accord-
ing to the blending power of the aromatic products, nor do I limit myself to any
particular order of admixture of the ingredients of my improved articles of per-
fumery, although on account of the action of the concentrated formaldehyde
solution on some aromatic products when undiluted, I prefer generally to dilute
the formaldehyde solution or the aromatic product by means of alcohol before
mixing the same.
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. The preparation of articles of perfumery by the addition of formaldehyde,
either in dissolved or gaseous form, to combinations of aromatic products with
alcoholic liquids or the like.
2. As improved articles of perfumery, mixtures of formaldehyde with alcoholic
or similar solutions of aromatic products, substantially as described.
