Novel odorant compositions comprising ethanol, perfume concentrate and panthenol.

The present invention is concerned with novel odorant compositions. More 
particularly, the invention is concerned with novel odorant compositions 
with prolonged diffusion after the application on the skin. 
It is well known that mixtures of perfume materials when deposited on the 
skin lose intensity and may change character with time, mainly due to 
factors such as differential evaporation and skin penetration. 
Many attempts have been made to minimize these drawbacks, but so far 
without notable success. Particularly, efforts have been made to prolong 
the diffusion, as well as to improve other characteristics of perfume 
materials, by e.g. increasing the perfume concentrate concentration or by 
using additives such as silicones, glycerol, polyethylene glycols and so 
on. Such perfume compositions, however, have never been really successful 
as the results obtained were only marginal. 
It thus actually existed a problem in this connection, which now has been 
overcome by the present invention. 
Surprisingly, it has now been found that the addition of panthenol 
significantly improves and particularly prolongs diffusion of perfume 
materials from the skin, without notably modifying the olfactive note of 
the product. The present invention thus concerns odorant compositions 
comprising from about 70 to about 99% of ethanol, from about 0.5 to about 
30% of perfume concentrate, from about 0.1 to about 20% of panthenol and 
from about 0% to about 30% of water. 
The term "odorant composition", as used in connection with this invention, 
means solutions of perfume materials in alcohol and stands for well known 
commercial products such as e.g. Deo-Cologne, Eau de Cologne, Eau de 
Toilette, Perfume Extrait and so on. 
The term "perfume concentrate" stands for the required mixture of perfume 
materials of synthetic and/or natural origin. 
The term "panthenol" as used in connection with the present invention 
stands for DL-panthenol or for D-panthenol. 
The percentages referred to in the scope of the present invention are on a 
weight by weight basis. 
The amount of perfume concentrate and thus also the amount of ethanol 
present depends upon the respective odorant composition and can be easily 
determined by the skilled artisan. The amount of panthenol can also vary 
within a range of from about 0.1 to about 20%, but lies preferably in the 
range of from about 0.5 to about 5%. By way of examples, in the following 
odorant composition the respective ingredients may be present in the 
following approximate amounts: 
______________________________________ 
a) Deo-Cologne: 
Perfume concentrate 0.5-3% 
Panthenol 0.5-2% 
Ethanol (98.degree.) q.s. 
b) Eau de Cologne: 
Perfume concentrate 2-7% 
Panthenol 0.5-3% 
Ethanol (88.degree. or 73.degree.) 
q.s. 
c) Eau de Toilette: 
Perfume concentrate 5-20% 
Panthenol 0.5-5% 
Ethanol (93.degree.) q.s. 
d) Perfume Extrait: 
Perfume concentrate 15-25% 
Panthenol 0.5-5% 
Ethanol (96.degree.) q.s. 
______________________________________ 
With the alcohol also water is introduced into the compositions, and the 
degrees of alcohol mean % v/v at 20.degree. C. 
Besides the ingredients mentioned before, the odorant compositions 
according to the present invention can also contain additives which are 
well known in the art. By way of example the following can be mentioned: 
colorants, UV-absorbants, antioxydants, preservatives, emollients, natural 
herbal extracts, germicides, deodorants and so on. If such additions are 
present their amount lies preferably between about 0.05 and about 2%. 
Furthermore, the odorant compositions can also contain vitamins, such as 
e.g. vitamin E, preferably in the form of the acetate, vitamin A, 
preferably in the form the acetate or any other common ester, vitamin C, 
preferably in the form of the palmitate, and so on.

The following examples are illustrative of the present invention and are by 
no means intended to limit the scope of the present invention.

In order to determine the efficacy of claimed odorant compositions the 
compositions according to Examples 2, 3 and 4 have been compared to 
analogous compositions containing no panthenol. The respective 
compositions were applied during several days to the left and the right 
arm of test persons who had then to identify which compositions have the 
longer diffusion after application and by how much the diffusion was 
extended. The results are summarized in the enclosed tables.
