Description
ANHYDROUS ANTIPERSPIRANT COMPOSITION COMPRISING A VOLATILE LINEAR C9-Ci7 ALKANE ; AEROSOL DEVICE
The present invention relates to an antiperspirant composition, characterized in that it comprises, in a cosmetically acceptable anhydrous liquid vehicle:
(a) at least one antiperspirant active principle;
(b) at least one volatile linear C9-Ci7 alkane or a mixture of volatile linear C9-C17 alkanes; and
(c) at least one propellant. The invention also relates to an aerosol device composed of:
(A) a container comprising a composition composed, on the one hand, of an anhydrous liquid phase (or dispensable) comprising at least one antiperspirant active principle .and at least one volatile linear C9-C17 alkane or a mixture of volatile linear C9-C17 alkanes, and
(B) at least one propellant and of a means for dispensing the said aerosol composition. The invention also relates to a method for the treatment of human perspiration and the human body odours and in particular axillary odours resulting therefrom using this composition.
In the cosmetic field, it is well known to use, in topical application, antiperspirant products comprising active substances of antiperspirant type to reduce the flow of sweat, indeed even to reduce body odours.
Antiperspirant substances have the effect of limiting the flow of sweat. They are generally composed of aluminium and/or zirconium salts.
The most widely used anhydrous aerosols in the field of antiperspirants mainly comprise a solid antiperspirant active principle suspended in an emollient oil by virtue of a modified clay. The phase proportion of dispensable to propellant generally lies within ratios of concentrations, expressed as percentage by weight, of between 10/90 and 30/70.
"Dispensable" is understood to mean the product
which is introduced into the aerosol device, to which a propellant gas is added in order to place it under pressure .
The qualities desired for an anhydrous antiperspirant composition in the aerosol form are:
- freshness and softness on application,
- no greasy feeling,
- ease of use due to a longer settling time.
The anhydrous antiperspirant aerosols known in the prior art generally comprise suspending agents of modified clay or silica type. However, the separation by settling of the antiperspirant active principle is often rapid and can result in nonhomogeneous deliveries of product. Moreover, the addition of these suspending agents, such as silicas, can cause blockage of the nozzle in the aerosol device. Clays, such as bentonites, can, for their part, introduce a greasy feel.
Furthermore, anhydrous antiperspirant aerosols generally comprise volatile emollient silicone oils which exhibit the advantage of having a good dry feel. However, the separation by settling of the antiperspirant active principle obtained in the presence of these volatile silicones often still remains excessively rapid and can result in deliveries of nonhomogeneous product.
The need thus remains to find novel anhydrous antiperspirant aerosol formulations having a rate of separation by settling of the antiperspirant active principle which can be substantially slowed down while simultaneously having good effectiveness and good cosmetic properties.
Three examples of antiperspirant compositions in the aerosol form are known from the published patent applications DE102008012457 and DE102008017031 :
After much research directed at this issue, the Applicant Company has now discovered, unexpectedly and
surprisingly, that, by partially or completely replacing the volatile silicones with at least one volatile linear C9-C17 alkane, anhydrous antiperspirant aerosol compositions are obtained in which the active principle settling time is substantially longer. The compositions in accordance with the invention simultaneously exhibit good effectiveness and good cosmetic properties.
This discovery forms the basis of the present invention.
A subject-matter of the invention is thus an antiperspirant composition, characterized in that it comprises, in a cosmetically acceptable anhydrous liquid vehicle: (a) at least one antiperspirant active principle;
(b) at least one volatile linear C9-C17 alkane or a mixture of volatile linear C9-C17 alkanes; and
(c) at least one propellant; with the proviso that the composition is different from the following formulations, in which the amounts of the ingredients are expressed as percentage by weight, with respect to the total weight of the composition:
The invention also relates to an aerosol device composed of:
(A) a container comprising a composition composed, on the one hand, of an anhydrous liquid phase (or dispensable) comprising at least one antiperspirant active principle and at least one volatile linear Cg-Ci7 alkane or a mixture of volatile linear Cg-Ci7 alkanes, and
(B) at least one propellant and of a means for dispensing the said aerosol composition; with the proviso that the composition formed by the said dispensable and the propellant is different from the above formulations A, B and C.
A second subject-matter of the present invention
is also a method consisting in using such a composition to prevent or limit the flow of sweat and thus to limit the body odours resulting therefrom.
"Anhydrous" is understood to mean, within the meaning of the invention, a composition having a content of free or added water of less than 3% by weight and preferably having a content of added water of less than 1% by weight, with respect to the total weight of the composition. The volatile linear alkanes in accordance with the invention comprise from 9 to 17 carbon atoms, in particular from 10 to 15 carbon atoms and more particularly from 11 to 13 carbon atoms.
The volatile linear alkanes in accordance with the invention can advantageously be of vegetable origin.
Such alkanes can be obtained, directly or in several stages, from a vegetable raw material, such as an oil, a butter, a wax, and the like.
Mention may be made, as examples of volatile linear alkanes suitable for the invention, of those described in the patent application from Cognis WO 2007/068371, DE102008012457 and DE102008017031.
These alkanes are obtained from fatty alcohols, themselves obtained from coconut or palm oil. Mention may be made, as examples of volatile linear alkanes suitable for the invention, of n-nonane (Cg) , n-decane (Cio) , n-undecane (Cn) , n-dodecane (C12) , n-tridecane (C13) , n-tetradecane (Ci4) , n-pentadecane (Ci5) , n-hexadecane (Ciε) and n-heptadecane (Ci7) , and their mixtures.
According to a particularly preferred form, use will be made of a mixture of undecane (Cn) and tridecane (C13) . More preferentially, the said mixture will comprise from 50 to 90% by weight of undecane and from 10 to 50% by weight of tridecane, with respect to the total weight of the mixture.
The volatile linear alkane or the mixture of volatile linear alkanes of the invention are preferably present in a content ranging from 10% to 95% by weight,
with respect to the total weight of the dispensable of the composition, and more preferably ranging from 30% to 95% by weight.

The ZAG complexes ordinarily exhibit an Al/Zr quotient ranging from approximately 1.67 to 12.5 and a metal/Cl quotient ranging from approximately 0.73 to 1.93.

Concrete but in no way limiting examples illustrating the invention will now be given. Examples
Two formulation examples 1 and 2 in the form of aerosols with 85% of propellant and 15% of dispensable were produced. The amounts of the various ingredients present are shown as percentages by weight.
Procedure
The whole of phase A (fatty phase) is weighed out in a beaker and mixing is carried out under an Ultra- Turrax at speed 2 for 15 min. Phase B (the thickener) is added little by little and the mixture is allowed to thicken, still under Ultra-Turrax stirring (speed 2), for 15 min. Finally, phase C (active principle) is added. Dispersing is carried out for 15 min. Subsequently, each of the formulations 1 and 2 is packaged in an aerosol container comprising 85% of isobutane (propellant) and 15% of dispensable.
Protocol for measuring the rate of settling
The measurment is carried out after pressurization . A demarcation line is traced, on a glass aerosol, at the level of the liquefied gas (at the top) and then a second demarcation line is traced
1 cm below. The aerosol is agitated manually for 10 seconds (time necessary to disperse the cake formed at the bottom of the aerosol) . The aerosol is immediately placed on a horizontal surface and the stopwatch is started as soon as the dispensable is positioned at the level of the top line. The stopwatch is halted as soon as the dispensable reaches the second line (1 cm below) . The time (in seconds) necessary in order for the dispensable to travel this distance is then determined. It is accepted that the rate of settling is within the standards when it is greater than or equal to 20 s.
