The development of formulations dedicated to caring for and/or making up the skin and/or lips, is permanent. Said formulations have to show satisfactory properties in terms of application, such as easy usage, and also in terms of sensory, such as hydration and/or moisturizing feeling after application.
The skin is the protective barrier for the human body. It protects the interior of the body from physical injury (such as trauma) and biological injury (such as bacteria, viruses or fungi). The skin of the human body comprises the dermis and the epidermis. The epidermis is the top most layer of the skin, and its superficial layer is called the stratum corneum.
Cosmetic compositions applied on skin may present different properties.
Two-phase compositions which appeal to consumers on account of their aesthetic nature currently exist on the market, but not in the form of a suspension having visible droplets. The current compositions generally consist of two mutually immiscible phases, which are mixed together extemporaneously by shaking before use.
The desire for light-colored and even-toned skin remains the most important factor driving demand for skin whitening products in the global cosmetics industry. In addition to skin lightening cream and lotion for the face, the retail market is inundated with skin-whitening solutions for body, armpits, elbows, arms and feet. Moreover, the conventional fairness products existing in the market mostly contain surfactants. These surfactants can be irritant for certain skins, specifically sensitive ones.
Thus, thefe is a need for surfactant free cosmetic compositions which may bring an effect of light-colored and even-toned skin.
However, cosmetic suspensions comprising visible oil droplets containing pigments in suspension in a gel or liquid carrier are not available today, as it is difficult to stabilize the droplets in such a formulation. They have a tendency to destabilize the product upon manufacture and on storage over time. Indeed the pigment droplets generally either settle or spurt eventually, thus affecting the aqueous phase; or they coalesce, leading to an unstable and unappealing product.

There is thus a need for a cosmetic composition which would be stable, while being not irritant, in the form of a suspension having visible oil droplets containing pigment suspended in carrier. Said composition would be used for caring, protecting and/or making up skin.
The Applicant has now discovered that it is possible to formulate such compositions having the desired properties as described above.
Specifically, the Applicant has discovered that it is possible to formulate compositions for caring for and/or making up of keratin materials, which are stable, non-irritant, which confer moisturization, hydration and/or softening after application onto skin, and which confer light-coiored and/or even-toned skin. Said compositions comprise visible oil droplets which are homogenously dispersed.
Accordingly, the present invention relates to a composftran, preferably a cosmetic composition, in the form of a stable oil-in-water dispersion, comprising:
a) oil droplets comprising at least one oil and at least one pigment; and
b) a continuous aqueous phase comprising at least one polymer chosen from a copolymer of ammonium acryloyldimethyltaurate, dimethylacrylamide, lauryl methacrylate and laureth-4 methacrylate, crosslinked with trimethylolpropane triacrylate; dehydroxanthan gum; and copolymers comprising at least one (meth)acrylate monomer and at least one monomer which is an ester of methacrylic acid with an ethoxylated fatty alcohol having a fatty chain of 15 to 30 carbon atoms,
wherein said composition is substantially free of surfactants.
The composition of the invention has the appearance of a homogenous dispersion of oil droplets, which are visible with the naked eye, in the aqueous phase. As it is stable, it does not need-to be shaken before use.
The composition of the invention is very easy to spread, while bringing a moisturizing feeling after application. The composition of the invention further shows a very good whitening benefit. Said composition is stable, and is processed at room temperature. Finally, said composition is substantially free of surfactants.
By "substantially free of surfactants", it is meant that the composition of the invention comprises less than 1% by weight, preferably less than 0.5% by weight, more preferably less than 0.3% by weight, preferably less than 0.1% by weight of the total composition of surfactants. More preferably, the composition of the invention is devoid of any surfactant.

By "stable", it is meant that the composition of the invention does not show any coalescence of the oil drcp'ets or dephasing (i.e. separation of the aqueous phase from the oil droplets which form a fatty phase), and does not show any pigment spurting, over time, especially during at least 14 days, under a high temperature (50°C).
Other subjects and characteristics, aspects and advantages of the invention will emerge even more clearly on reading the description and the examples that follows.
In that which follows and unless otherwise indicated, the limits of a range of values are included within this range, in particular in the expressions "of between" and "ranging from ... to ...".
Moreover, the expression "at least one" used in the present description is equivalent to the expression "one or more".

scattering using a commercial granulometer such as the MasterSizer 3000 machine from
Malvern. The data are processed on the basis of the Mie scattering theory. This theory,
35 which is exact for isotropic particles, makes it possible to determine, in the case of non-

Conclusion:
Results of Table 2 indicate that formulations F1, F3 and F5 are the single formulations which give stable gels with visible droplets which are uniform in size and show good sensorial.
Formula F1 was tested on voluntary women, and was shown to bring skin lightening and instant skin whitening. It was also evaluated as moisturizing.
