Description

COSMETIC COMPOSITIONS IN THE FORM OF WATER-IN-OIL EMULSIONS INCLUDING A JASMONIC ACID DERIVATIVE AND A SILICONE SURFACTANT
This invention relates to skincare and/or makeup compositions. More specifically, the invention relates to cosmetic compositions in the form of water-in-oil emulsions, including a jasmonic acid derivative and a specific silicone surfactant.
Consumers look for cosmetic skincare or makeup products that can be easily and quickly spread on the skin in the form of a deposit that should not be thick, but that should instead blend as much as possible with the support, and they also look for anti-aging products.
Consumers are therefore increasingly looking for cosmetic products that combine foundation makeup properties and skincare properties, in particular for fighting the effects of aging.
These products usually contain active ingredients recognized for their anti- aging activity and colored particles such as pigments or nacres enabling the signs of aging to be hidden.
Among anti-aging active ingredients, it is possible to cite alpha-hydroxy acids such as lactic acid and citric acid, beta-hydroxy acids such as salicylic acid, and also jasmonic acid derivatives in particular described in the application EP 1 333 021 .
These jasmonic acid derivatives have the advantage of being well tolerated and of not causing skin discomfort such as tingling, tightness or redness.
However, the addition of these compounds to cosmetic formulations, in particular in the form of emulsions, may significantly alter their stability and cause a phase change or a reduction in viscosity over time.
There is therefore a need to provide compositions in the form of W/O emulsions that are stable and that have good cosmetic application properties.
This invention is intended to provide water-in-oil emulsions intended for use in skincare and/or makeup compositions.
This invention is intended to provide skincare and/or makeup compositions in the form of water-in-oil emulsions that are stable over time.
This invention is intended to provide skincare and/or makeup compositions having a good compromise between stability and cosmetic properties.
Thus, the invention relates to a composition, in the form of a water-in-oil emulsion including an aqueous phase dispersed in a fat phase, in which said composition includes a physiologically acceptable medium containing: - at least one jasmonic acid derivative compound with the following formula (I):

EXAMPLES
Examples 1 to 6: Influence of the nature of the surfactant
Examples 1 to 6 of the W/O emulsion make it possible to show the influence of the structure of the surfactant on stability.
For all of these examples, the surfactant content is 2% by mass. When the latter is mixed with one or more other constituents, the content of the mixture is adjusted so as to preserve this value.
Figure imgf000026_0001
The compositions of examples 1 to 6 were prepared according to the following procedure.
Procedure
The constituents of phase A are weighed into the main beaker, then homogenized using a Raynerie mixer at a speed of 400 rpm at room temperature.
The constituents of phase B are weighed separately and homogenized by means of a magnetic mixer at room temperature.
Then the emulsification is produced by pouring phase B into the main beaker while progressively increasing the agitation speed to 2500 rpm, which agitation is then continued for 5 to 10 minutes according to the consistency of the product.
It is then agitated for two more minutes at 1500 rpm and the product is packaged in a glass jar.
Emulsification results The macroscopic quality of the emulsion is examined once the agitation has been completed:

Figure imgf000029_0001
Procedure
The constituents of phase A1 are weighed into the main beaker, then homogenized with a Moritz mixer at a speed of 1200-1400 rpm at room temperature.
Phase A2 followed by phase A3 are then added, which have been previously prepared by mashing by hand, and, finally, phase A4 is added, while agitating for 15 minutes until homogenization.
Phase A5 is prepared separately by grinding three times, in a three-roll mill, the mixture of pigments and cyclohexasiloxane. Phase A5 is added to the main beaker while progressively increasing the agitation speed of the Moritz mixer to 1400-1500 rpm, then the agitation is continued for 20 minutes while keeping the beaker at room temperature by means of a water bath.
The constituents of phase B are weighed separately, with the exception of the jasmonic acid derivative and the phenoxyethanol. It is homogenized using a magnetic mixer at a temperature of around 30-35°C, then the jasmonic acid derivative and the phenoxyethanol are incorporated.
Then the emulsification is produced at room temperature by pouring phase B into the main beaker and progressively increasing the agitation speed to 4000 rpm, and then maintaining it at that speed for 10 minutes.
The agitation speed is then slightly reduced and the ethanol and the perfume are added. The mixture is agitated again for two minutes and the product is packaged in a glass jar.
Stability results
The formulas of examples 12 and 13 are stable for 1 month at 4<Ό, 20°C and 37°C, i.e. they do not show any macroscopic change at these temperatures.
The stabilities at room temperature (20 'Ό) are tested on 300g of product, packaged in a 660ml glass jar that is hermetically sealed with an aluminum lid.
The stabilities at 4°C and 37 <Ό are tested on 20g of product, packaged in a 30ml glass jar that is hermetically sealed.
