COSMETIC COMPOSITIONS IN THE FORM OF WATER-IN-OIL EMULSIONS
INCLUDING A JASMONIC ACID DERIVATIVE
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.
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 antiaging
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.
To overcome this disadvantage, it is possible to increase, in the case of waterin-
oil emulsions (W/O), the dispersed aqueous phase content, which enables
stability to be improved by increasing viscosity. However, if the water content is too
high, the cosmetic application properties of the composition are altered.
There is therefore a need to provide compositions in the form of a W/O
emulsion 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.
This invention relates to a composition including a physiologically acceptable
medium containing:
- at least one coloring agent; and
- at least one jasmonic acid derivative compound with the following formula (I):
in which:
. R represents a radical COOR3, with R3 designating a hydrogen atom or a
C1-C4 alkyl radical, optionally substituted by one or more hydroxyl groups;
. R2 represents a hydrocarbon radical, saturated or unsaturated, and linear
with 1 to 18 carbon atoms, or branched or cyclic with 3 to 18 carbon atoms;
as well as their optical isomers and corresponding salts;
wherein said composition is in the form of a water-in-oil emulsion including an
aqueous phase dispersed in a fat phase,
wherein said aqueous phase represents 40% to 55%, in particular 42% to 52%, and
preferably 44% to 50%, by weight with respect to the total weight of said
composition.
The compositions according to the invention are cosmetic compositions
intended for skincare and/or makeup.
The emulsions obtained have good stability over time, a pleasant appearance
and, during application, comfortable sensation properties.
The term "stable emulsion" refers to an emulsion that, after 7 days of storage
at room temperature (20-22 °C), does not show any macroscopic change in color,
odor or viscosity.

The particles with a metallic sheen capable of being used in the invention are
in particular chosen from:
- particles of at least one metal and/or at least one metal derivative,
- particles comprising an organic or inorganic substrate, made of a single
material or of multiple materials, covered at least partially by at least one layer with a
metallic sheen, including at least one metal and/or at least one metal derivative, and

company (Darmstadt). For example, these pigments may be pigments with a silica /
titanium oxide / tin oxide structure sold under the name XIRONA MAGIC by the
MERCK company, pigments with a silica / brown iron oxide structure sold under the
name XIRONA INDIAN SUMMER by the MERCK company and pigments with a

large 0.3m3 chamber temperature-controlled at a temperature of 25 C, and
humidity-controlled with a relative humidity of 50%. The liquid is left to evaporate
freely, without stirring, by providing ventilation with a fan (PAPST-MOTOREN,
reference 8550 N, rotating at 2700 rpm) positioned vertically above the crystallizer
containing the solvent, with the blades directed toward the crystallizer and at a

Procedure
The constituents of phase A 1 are weighed into the main beaker, then
homogenized using 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.
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 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
These results show that the composition is stable when the aqueous ph
percentage is greater than 40%.
B - Influence of the aqueous phase content on cosmetic properties
The comparison of the fluid foundation examples 1 and 8 shows that, when
the aqueous phase content is greater than 55%, the cosmetic properties of the
foundation are not as good.

Procedure of example 8
The constituents of phase A 1 are weighed into the main beaker, then
homogenized with a Moritz mixer at a speed of 1500 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 1600 rpm, then the agitation is continued for
20 minutes.
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 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.
Sensory evaluation
We asked a panel of 4 women, between the ages of 20 to 50 years, to apply
the two foundations, one on each half of their face.
This evaluation showed found that the foundation of example 1 (invention) is
easier to apply, smoother and more comfortable. The foundation of example 8
(comparative) gives a more powdered makeup result, which has a tendency to
increase the visibility of raised imperfections (pores, wrinkles). After application, it
leads to a harder and stickier film.
In the end, the women on the panel prefer the foundation of example 1
(invention).
