TECHNICAL FIELD
[0002] The present application relates to a composition, preferably a cosmetic or dermatological composition, comprising a combination of specific ingredients. BACKGROUND
[0003] In recent years, the emulsion market has been growing in North Asia and expanding globally. In terms of viscosity, the variety of emulsions is not so much, as they tend to have very low viscosity.
[0004] However, the lower the viscosity becomes, the more unstable the emulsion becomes. Thus, the color, odor and pH of the emulsion can change. In addition, phase separation or creaming can occur due to the aggregation of one or more oils in the emulsion.
[0005] Furthermore, there is still a need for emulsions that can provide a good texture, such as a smooth skin finish. SUMMARY
[0006] It is an object of the present application to provide a composition that is not only stable at low viscosity but also can provide a good texture, such as a smooth feel after application.

[0032] The present application also relates to a cosmetic process for treating keratin materials, comprising the step of applying to the keratin materials a composition according to the application. DETAILED DESCRIPTION
[0033] After diligent research, the inventors have discovered that it is possible to provide a composition which not only makes it possible to achieve a low viscosity, but which is also stable, and which makes it possible to provide a good texture, such as a smooth feel after application.
[0034] The composition according to the application is characterized by the following combination:
[0035] at least one relatively heavy oil;
[0036] at least one second polyglyceryl fatty acid ester having a specific HLB value range;
[0037] at least one anionic surfactant; and
[0038] at least one acrylic thickener.
[0039] An aspect of the application is therefore a composition comprising:
[0040] (a) at least one oil;
[0041] (b) at least one polyglyceryl fatty acid ester having an HLB of 8 to 11 ;
[0042] (c) at least one anionic surfactant;
[0043] (d) at least one acrylic thickener; and
[0044] (e) water,
[0045] wherein the specific gravity of the (a) oil(s) at 25°C is greater than 0.95, preferably greater than 0.96, and more preferably greater than 0.97.
[0046] The term "specific gravity" is well known as the ratio of the density of a target substance to the density of a standard substance. Here, the "specific gravity" means the ratio of the density of the oil(s) to the density of water (1 g / cm 3 ) at 25°C.
[0047] The composition according to the present application not only achieves low viscosity but also is stable. Therefore, even if the composition according to the present application has low viscosity, phase separation or cream layering of the composition can be prevented or reduced.
[0048] Here, the term "stable" reflects temperature stability and means that the appearance of the composition does not change over time at various constant temperatures such as 4°C, 25°C, 40°C, and 45°C.
[0049] Further, the composition according to the present application can provide good texture, for example, smooth touch after application. In other words, the composition according to the present application is not sticky after being applied to a keratin material (for example, skin). Here, the term "sticky" means a property that provides a sticky feeling to the skin.
[0050] Therefore, the composition according to the present application is particularly suitable for an emulsion having low viscosity.
[0051] Hereinafter, the composition according to the present application will be described in detail.
