Description

Description Title: Oil-in-water cosmetic composition comprising pigments Technical area The present invention relates to the field of cosmetic compositions of the type emulsion oil-in-water (HIE) comprising pigments, particularly dedicated to makeup as for example compositions for foundation, and the use of these oil-in-emulsions water (O/W) as a foundation.
Technology background There is a strong demand for cosmetic compositions improving the appearance of the skin. In particular, makeup compositions such as foundations complexion, helps to beautify and even out the complexion or hide imperfections skin or skin irregularities such as spots, hyperpigmentation, pigs, wrinkles and fine lines. Foundation compositions must have good adhesion to skin powders and particulate coloring materials and a uniform dispersion of these powders and pigments so as to allow good spreading properties, makeup covering and homogeneous as well as good hold.
It is generally easier to make foundations in the form water emulsion in-oil to obtain good spreading properties, coverage and of homogeneity.
But oil-in-water emulsions (or direct emulsions) are particularly appreciated in the cosmetic field for the sensation of freshness they provide the application. We know, for example, oil-in-water compositions pigmented described in application W02016/087554 comprising an associative polyurethane, a surfactant no ionic, a fatty alcohol and 10% by weight of pigments coated with a compound hydrophobic.
However, oil-in-water emulsions are less suitable for products complexion because they have sensory properties that are less appropriate for this type of product that water-in-oil emulsions, particularly low slipperiness, good coverage insufficient and a application or handling time (play time) too short to be able to work the composition upon application and allow easy and uniform application of the colour.
In addition, compositions with high pigment contents are generally more difficult to stabilize without substantially compromising the sensory properties.
In addition to the instabilities linked to the emulsion (such as creaming, flocculation), other instabilities may be linked to migration, sedimentation or the agglomeration

2 pigments. However, good dispersion of pigments is essential and can be more difficult to be obtained with direct emulsions. These various instabilities can lead to changes in textures and/or hues of the composition over time.
Some Instabilities can also lead to a noticeable difference in color between that of the mass of the product (color of the composition) and that finally obtained a time that the composition is applied in the form of a film to the skin.
Finally, it is more difficult to obtain direct emulsions presenting, after application, satisfactory properties in terms of resistance over time. This lack of outfit can be in further exacerbated depending on temperature and humidity conditions surrounding. A
destabilization of the makeup film on the skin will have the effect of provoke, in a few hcurcs, a visual rendering of makeup that is heterogeneous and therefore unsatisfactory.
There thus remains the need to have cosmetic compositions, in particular For makeup or complexion products, which are effective in unifying the complexion and correct the imperfections and which have good spreading and holding properties with a result uniform, covering and natural on the skin. There is also a need for to have available cosmetic compositions for makeup which provide a sensation of freshness and lightness on application, while having good sensory properties, particularly easy to apply and spread, without feeling of braking upon application, no sticky, pleasant touch, leaving no greasy feeling and comfortable to wear throughout along the daytime.
In particular, there remains a need for cosmetic compositions for makeup, especially for foundations, which provide a sensation of freshness while presenting good sensory properties, good slipperiness, good ease spreading with a sufficient play time, good coverage and allowing to obtain a uniform makeup result.
At the same time, there is a need to have compositions cosmetics presenting good stability over time, in particular which are stable during the entire period of storage of the product until several months after its opening by the end user.
The applicant discovered in an unexpected and surprising manner that the whole death problems can be solved by the composition according to the present invention.
Summary of the invention According to one aspect, the present invention relates to a cosmetic composition form oil-in-water emulsion comprising at least one dispersed oily phase in aqueous phase and comprising:
a) at least one alkyl phosphate emulsifier;
b) at least one polyoxyalkylenated silicone emulsifier;

3 c) at least one aqueous thickener chosen from patterned polymers sulfonic; And d) at least one pigment treated on the surface with a silicone treatment agent polyoxyalkylenated.
Indeed, after much research, the inventors discovered that it is possible to provide a complexion product in the form of an oil-in-water emulsion, having Properties sensory properties of a water-in-oil emulsion, in particular very good ease spreading with good slipperiness and a sufficiently long handling time (play time ), all in retaining the qualities of freshness and lightness of oil-in-emulsions water. In others terms, the inventors have developed a composition making it possible to accumulate advantages of two different galenics. In particular, the compositions according to the invention allows a good distribution of pigments which, surprisingly, blend into the skin and provide good natural coverage and a uniform makeup result, which allows to unify the complexion but also to hide the imperfections of the reliefs skin, as by example wrinkles, fine lines and pores.
The particular combination of ingredients highlighted by the inventors allow to obtain a composition presenting both this sensoriality and maneuverability in application, very good homogeneity of color and hold as well as very good stability in the time.
Finally, the composition according to the invention has the advantage of obtaining oil-emulsions stable in-water without requiring significant proportions of surfactants, emulsifiers and thickeners. The body and the stability of the particular association of ingredients allows in addition to the integration of mineral or organic solar filters for daily protection without degrading the sensory properties or destabilizing playtime or coverage.
The composition according to the invention is suitable for topical application on the skin. She can be used for care and/or makeup, particularly for the skin. By example, she can be used as a skin care product, for example as a face cream protection, of treatment or care for the face, hands or body, or as a product of sunscreen. The composition according to the invention can also be used as product for skin makeup, particularly as a foundation.

Procedure for compositions 1 to 7:

An aqueous phase A is prepared by dissolving EDTA in a beaker disodium in water with stirring. Phase A is maintained under stirring Rayneri equipped of a deflocculator at 250 rpm (rotation per minute) for approximately 10 minutes and until dissolution of disodium EDTA. Furthermore, a phase B is previously prepared in mixing glycerin, propanediol and ethylhexylglycerin. Phase B
is then added to phase A and the whole is stirred for 5 minutes at 250 rpm. The thickener aqueous acryloyldimethyltaurate copolymer (phase C) is then added to the mixture aqueous previous. Everything is stirred until homogenized by increasing gradually the speed from 400 to 800 rpm. Then, the sodium polyacrylate (phase D) is added and the agitation is maintained for 5 minutes at 1000 rpm before heating everything to 80-85 C using of a plate heating. Phase E (alkyl phosphate or, where applicable, the mixture of DC esters polyglyceryl) is added to the hot mixture and stirring is maintained between 1000 and 1200 rpm for 10 minutes at 80-85 C. Phase F (polyoxyalkylenated silicone or, the case optionally, the mixture of stearic acid esters) is then added to the mixture hot watery and stirring is maintained at 1000 rpm for 5 minutes at 80-85 C.
The emulsion is then carried out by incorporating, with stirring (1500 to 1600 rpm), the fatty phase (phase G
comprising dimethicone) previously heated to 80 C, in the phase watery maintained at 80-85 C. Stirring is maintained (1500 rpm) for 10 minutes After the formation of the emulsion, always at 80-85 C. The heating plate is then removed for allow the mixture to cool, still stirring (1100 rpm). When the mixture arrives at 50 C, the pigments (phase H) are added and everything is homogenized under unrest in 2000 rpm for 10 minutes. Phase I (mixture of dimethicone and dimethiconol) is then added to the mixture and stirring is maintained for 5 minutes at 1100 rpm.
Phase J
(mixing a little water with the GRANSIL SIW-078 premix) is then added and stirring is maintained for 3 minutes at 1100 rpm. Once the mixture has reached 40 C, the perfume (phase K) is added and stirring is maintained for 3 minutes at 1100 rpm. A
composition for foundation is thus obtained.
Procedure for composition 8:
In this operating mode, the pigments used are in the form of a ready-made dispersion the use of iron oxide or titanium dioxide particles in a mixture water/glycerin.
The italicized percentages given in Table 2 take into account the overall percentage of each of these components in the final composition (glycerin and a part of the water being provided by the commercial dispersion of pigments used).
In this operating mode, disodium EDTA is dissolved in 43.82% water under stirring to prepare an aqueous phase A. This phase A is kept under stirring Rayneri equipped with a deflocculator at 250 rpm. A phase B is previously prepared in mixing propanediol and ethylhexylglycerin. This phase B is then added to the phase A and the whole is stirred for 5 minutes at 250 rpm. To this aqueous mixture are added the ready-to-use pigment dispersions (phase H): in total 23.88% by weight of dispersions are added, representing 11.94% by weight of pigments (per relation to weight total of the final composition) and 5.97% by weight of glycerin (relative to the total weight of the final composition). Everything is kept stirring for 5 minutes.
at 400 rpm. THE
phases C, D, E, F, G, I, J and K are then added in the same way as in the mode procedure described previously for compositions 1 to 7. A composition for background complexion is thus obtained.
Evaluations and observations:
- Stability:
The stability of the above compositions was studied after preparation and after storage in accelerated conditions at 40 C for 3 months (in a thermostatically controlled oven).
The compositions were evaluated by sensory analysis (appearance, color and smell). The appearance overall is evaluated with the naked eye and with a microscope (Olympus BH2 Microscope Magnification 10x10) in order to control the color, the surface, the possible phenomena of release, of phase separation, sedimentation or agglomeration, as well as the possible presence of precipitates, phase shift or volute. The smell is compared with the composition witness (stored in the dark at 20 C or in the refrigerator). The results are listed in the table 3 below, in which the following notation is used:
C= compliant (absence of phenomenon showing instability) NC= non-compliant (phenomena showing instability such as breakage of the emulsion, a inhomogeneous mixture, etc.).
Table 3:

2 NC Unstable emulsion, distribution no homogeneous pigments 3 NC Broken emulsion 4 NC Broken emulsion 5 NC The emulsion is not made 6 NC Presence of pigment agglomerates 7 NC Presence of pigment agglomerates

8 NC Unstable emulsion Compositions 2 to 8 do not present a satisfactory appearance to allow a good application and a homogeneous result, unlike the composition according to the invention. THE
results show that the particular combination of ingredients according to the invention allows to obtain a composition with a homogeneous distribution of pigments. There composition according to the invention also has very good stability over time, contrary to to comparative compositions. In fact, composition 1 according to the invention is stable in the accelerated conditions generally used in cosmetics to guarantee stability in time, such as 3 months at 40 C. Here, composition 1 is also stable in more severe conditions such as 1 month at 50 C in a thermostatically controlled oven.
- Sensory:
5 Five expert panelists evaluated the texture and sensory properties of the face powder obtained according to composition 1 of the invention, and in particular the softness, the effect non-sticky, freshness upon application, slipperiness, duration of handling (play-time), coverage and the uniformity of the film obtained.
Composition 1 according to the invention has a soft, fine texture, not sticky and not 10 fatty touch. In addition, the texture is light and does not provide a feeling of heaviness.
Surprisingly, composition 1 according to the invention combines both a Good freshness upon application, very easy spreading with good glide, duration sufficiently long manageability and good coverage. In particular, the composition according to the invention makes it possible to obtain uniform makeup without marking the imperfections of the 15 skin (such as pores or fine lines). The composition according to the invention combines thus a fresh effect with good sensory properties and good homogeneity of color and of sprawl.

Procedure for compositions 9 to 12:
An aqueous phase A is prepared by dissolving EDTA in a beaker disodium in water with stirring. Phase A is maintained under stirring Rayneri equipped of a deflocculator at 250 rpm (rotation per minute) for approximately 10 minutes and until dissolution of disodium EDTA. Tromethamine (phase B) is then added in order to make the mixture basic before introducing the sulfonic acid phenylbenzimidazole (phase C), still under Rayneri stirring with deflocculator. The agitation is maintained until solubilized. Furthermore, a phase D is prepared by mixing glycerin, propanediol, ethylhexylglycerin and phenoxyethanol. Phase D is then added to previous aqueous mixture (A+B+C) and everything is stirred, still stirring Rayneri with deflocculator. Acryloyldimethyltaurate copolymer aqueous thickener (phase E) is then added to the previous aqueous mixture. Everything is agitated until homogenization in gradually increasing the speed from 400 to 800 rpm. If applicable, the compound alkyl phosphate (phase F for compositions 9, 10 and 11) is added to the blend previous under agitation detloculcusc Rayncri. Then, if necessary, silicone emulsifier polyoxyalkylenated (phase G for compositions 9, 10 and 12) is added under hustle Rayneri deflocculator. Furthermore, an H phase is prepared by mixing under stirring Rayneri deflocculator ethylhexyl salicylate, homosalate, octocrylene, UV filter inorganic and dimethicone. The H phase is then added to the mixture previous watery with stirring deflocculates Rayncri and the emulsion obtained is stirred for 5 minutes. THE
pigments (phase I) are then added and everything is homogenized for 5 minutes under stirring Rayneri deflocculator. In the case of composition 12 (the emulsion of which after phase addition fatty is heterogeneous and not smooth), a J phase (mixture of dimethicone and dimethiconol) is added to the previous mixture and stirring is maintained for 5 minutes. A
composition for foundation is thus obtained.
Results :
Comparative composition 11 differs from composition 9 according to the invention in what she doesn't does not contain the polyoxyalkylenated silicone emulsifier (PEG-11 Methyl Ether Dimethicone).
The evaluations show that, from 24 hours of storage, composition 11 presents an aspect less luminous, grayer and more heterogeneous (lumpy) than composition 9 according to the invention.
Comparative composition 12 differs from composition 10 according to the invention in that she does not contain the compound alkyl phosphate (potassium cetyl phosphate). THE
evaluations show that, from 24 hours of storage, the stability of composition 12 is compromised with a non-smooth appearance and non-homogeneous emulsion.
Furthermore, the evaluation of the sensory properties shows that the comparative composition 11, although it applies easily and has a dry feel after 5 minutes (dry quickly), it has a sticky texture and marks the pores. She also has a touch more rough (less smooth and soft when passing with a finger).
Composition 10 according to the invention combines a good fresh effect and an appearance smoother than composition 12. It is also felt as less sticky, less rough, more fine on the skin, with more playtime.
Composition 9 according to the invention also combines a fresh effect with a Good homogeneity of color and spreading.
In conclusion, the combination of ingredients according to the present invention allows to obtain homogeneous and stable oil-in-water compositions over time, even with a content high in pigments, while combining both a fresh effect upon application (characteristic oil-in-water emulsions) and spreading properties comparable to those of water-in-oil emulsions, in particular good glide, a duration of maneuverability sufficiently long and uniform makeup with good coverage, without training dc packs and without marking skin imperfections (piglines or fine lines).
