DESCRIPTION:
BRIEF SUMMARY
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 a manner known per sea Deo-Cologne of the following composition has been prepared:
