[0001] The present invention relates to a cosmetic composition. In particular, the present invention relates to a composition for caring for and / or making up keratin materials. In addition, the present invention also relates to a non-therapeutic method for caring for and / or making up keratin materials.BACKGROUND ART
[0002] The development of products dedicated to caring for and / or making up the skin and / or lips, is permanent.
[0003] For example, some products are developed to nourish the skin by forming a nourishing film on the skin.
[0004] There are some commercial products for nourishing the skin comprising a large amount of oil.
[0005] However, some products comprising a large amount of oil are not satisfying since they deliver a greasy sensory.
[0006] It is desired that such cosmetic compositions do not deliver a greasy sensory.
[0007] It is also desired the products for nourishing the skin is stable.
[0008] Thus, there is still a need to formulate a stable composition for caring for and / or making up keratin materials, especially the skin, which can nourish the keratin materials, especially the skin, and / or deliver a fresh sensory.
[0009] In addition, the formulation of environmentally-friendly cosmetic products, which are designed and developed considering environmental issues, is becoming a major goal in an effort to meet global challenges.
[0010] It is therefore essential to propose more sustainable compositions to address these environmental concerns.
[0011] In this context, it is important to develop new ingredients and / or active ingredients respectful of the environment, particularly of natural origin, more specifically bio-sourced and / or from sustainable sources not from petrochemicals, and / or biodegradable and / or obtained by extraction processes requiring low energy and water consumption in order to offer compositions that reduce the environmental impact of products.SUMMARY OF THE INVENTION
[0012] The inventors have now discovered that it is possible to formulate such compositions having the desired properties as described above.
[0013] Specifically, the inventors have discovered that it is possible to formulate stable compositions, preferably for caring for and / or making up of keratin materials, which can nourish the keratin materials, especially the skin, and deliver a fresh sensory.
[0014] Accordingly, in a first aspect, the present invention relates to a composition, preferably for caring for and / or making up keratin materials, comprising:

[0016] (ii) at least one alkyl polyglucoside; and
[0017] (iii) at least 12 wt. %of at least one fatty compound, relative to the total weight of the composition.
[0018] The inventors have found that the composition according to the present invention is stable and can nourish keratin materials well, in particular the skin.
[0019] The inventors have further found that in some preferred embodiments, the composition according to the present invention can deliver a fresh sensory.

[0083] Pasty compounds
[0084] As used herein, the term "pasty" refers to a lipophilic compound with a reversible solid / liquid change of state, notably having in the solid state an anisotropic crystal organization and comprising a liquid fraction and a solid fraction at room temperature.
[0085] In other words, the starting melting point of the pasty compound may be lower than room temperature. The liquid fraction of the pasty compound, measured at room temperature, may represent 9%to 97%by weight of the pasty compound. This fraction that is liquid at room temperature preferably represents between 15%and 85%, more preferably between 40%and 85%, by weight.
[0086] As mentioned herein, the melting point corresponds to the temperature of the most endothermic peak observed on thermal analysis (DSC) as described in standard ISO 11357-3; 1999. The melting point of a material may be measured using a differential scanning calorimeter (DSC) , for example the calorimeter sold under the name MDSC 2920 by TA Instruments or the calorimeter sold under the name DSC Q100 by TA Instruments with the TA Universal Analysis software.
[0087] The measurement protocol for the melting point of a pasty compound is as follows:
[0088] A sample of 5 mg of pasty compound placed in a crucible is subjected to a first temperature rise passing from-20℃ to 100℃, at a heating rate of 10℃ / minute, it is then cooled from 100℃ to-20℃ at a cooling rate of 10℃ / minute and it is finally subjected to a second temperature rise passing from -20℃ to 100℃ at a heating rate of 5℃ / minute. The melting point of the pasty compound is the value of the temperature corresponding to the top of the peak on the curve representing the variation in the difference in power absorbed as a function of the temperature.
[0089] It should be noted that the liquid fraction by weight of the pasty compound at room temperature is equal to the ratio of the heat of fusion consumed at room temperature to the heat of fusion of the pasty compound.
[0090] The heat of fusion of the pasty compound is the heat consumed by said substance in order to pass from the solid state to the liquid state. The pasty compound is said to be in the solid state when all of its mass is in crystalline solid form. The pasty compound is said to be in the liquid state when all of its mass is in liquid form.
[0091] The heat of fusion of the pasty compound is the amount of energy required to make the pasty compound change from the solid state to the liquid state. It is expressed in J / g. The heat of fusion of the pasty compound is equal to the area under the curve of the thermogram obtained.
[0092] The pasty compound may in particular be chosen from synthetic pasty compounds and fatty compounds of plant origin.

[0186] Fresh sensory and nourish residue
[0187] Fresh sensory and nourish residue delivered by each of compositions of invention examples 1-2 and comparative examples 1-3 were evaluated by 5 skin experts as follows.
[0188] 0.1 ml of a sample to be evaluated was took onto the back of a hand with a pipette and applied with fingers for 20 rounds (1 round / second, applied in diameter 5 cm) and the fresh sensory was scored by each skin expert within 1-5 according to the following standard and then averaged.
[0189] 1: Skin feels excessively oily and looks very shiny
[0190] 2: Skin feels noticeable oily and looks noticeable shiny
[0191] 3: Skin feels slightly oily and looks little shiny
[0192] 4: skin feels little watery and looks little watery radiant
