DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD AND PRIOR ART
The present invention relates to the perfume and cosmetic industry and, more particularly, to that of the body deodorants and antiperspirants.
The main function of a body deodorant or antiperspirant is that of preventing body malodor due to the bacterial decomposition and to the oxidation of the organic substances which make up the sweat. Conventionally, deodorants contain substances which are capable of masking this body malodor and of inhibiting the proliferation of the bacteria responsible for the deterioration of sweat, whereas antiperspirants comprise components which reduce perspiration while having a bactericidal activity.
In both instances, there is at present a tendency from the consumer to prefer deodorant products based on natural or nature identical (i.e., based on substances which are synthesized but the structure of which is identical to that of naturally occurring compounds) active principles. To satisfy this demand, one seeks to suppress in the body deodorants and antiperspirants the conventional bactericidal, bacteriostatic and antiperspirant substances, which are often allergenic, and to replace them by natural active principles. Thus, one has observed in the last few years the development of products whose bactericidal action is due essentially to the presence of perfuming compositions containing carefully selected perfuming ingredients, so as to ensure an adequate deodorising action without resorting to the classical bactericidal substances [see for example, G. W. Holzner in Aerosol Report 25, 354 (1986); see also published patent application EP 451 889 which contains quite a complete analysis of the art knowledge in the field of the bactericidal activity of synthetic or natural origin perfuming ingredients].
Another particular example of a composition representing this tendency is that of the compositions described in European patent application N.degree. 433 132, which comprise essential oils having an anti-bacterial and/or an anti-fungus activity dispersed in an aqueous phase stabilised by means of a lipid phase which comprises anionic and non-ionic amphiphile lipids.
On the other hand, a choice body deodorant must present as large a spectrum of bactericide activity as possible, i.e., it must prevent, as efficiently as possible, the growth of all the microbial organisms present on the skin. However, it is well known that the deodorant products based on perfuming substances do not have the same efficiency against all these varieties of organisms.
The aim of the present invention is to bring an original contribution to the solution of this problem.
DESCRIPTION OF THE INVENTION
The invention relates to a perfuming composition characterized in that it contains a cationic phospholipid, a perfuming base having antimicrobial activity ("PBAA") and a fatty alcohol having from 10 to 22 carbon atoms.
We have in fact discovered that the simultaneous presence of these three ingredients in the perfuming composition made it possible to inhibit the action of a great variety of microorganisms and imparted to said composition a remarkable deodorant power which rendered it particularly convenient for application in deodorant and antiperspirant articles, as it can be seen from the examples presented further on. It was surprisingly observed that the presence of the "PBAA" and of the fatty alcohol reinforced, in a synergic manner, the action of the cationic phospholipids and made it possible to obtain improved perfuming compositions, relative to the prior art ones.
Furthermore, we have also observed that the compositions according to the invention could have a considerable antiperspirant effect, even without resorting to the use of aluminium or aluminium and zirconium salts, currently used as active antiperspirant substances.
The cationic phospholipids are nature identical substances which are commonly used in cosmetics as emulsifiers or emollients. However, to our knowledge, there is no description in the literature concerning the use of these substances in body deodoran
