Description

Technical Field

[0001] The present invention relates to a composition, preferably a cosmetic composition, more preferably a stable sunscreen cosmetic composition with improved aesthetic feeling.

Background Art

[0002] Giving a comfortable texture to the skin is one of the main characteristics of cosmetics, especially sunscreen cosmetics.

[0003] Compositions that are unstable and easily cause the collapse of the composition structure should often be noted for providing a comfortable feeling of use. This means that it is difficult to simultaneously bring both a comfortable feeling during use and good stability.

[0004] So far, several techniques related to gel-like compositions or emulsion compositions that impart improved texture and stability have been reported.

[0005] For example, JP H11-246379A discloses a sunscreen cosmetic containing components of (A) ethanol, (B) starch powder having an average primary particle diameter of 1 μm or more and / or anhydrous silicic acid, and (C) a UV light scattering agent and / or a UV light absorber.

[0006] Also, WO 2007 / 144670 is a skin care composition in the form of an emulsion, a) an organic sunscreen component containing at least one sunscreen agent selected from the group consisting of bis-ethylhexyl oxy-phenol methoxyphenyl triazine and methylene bis-benzotriazolyl tetramethylbutyl phenol, b) a moisturizing system containing starch or a derivative thereof having wetting properties and a polymer quaternary compound salt, and c) a carrier containing an oil phase, an aqueous phase, and an emulsifying system, wherein the emulsifying system contains at least one emulsifier selected from anionic or nonionic emulsifiers, the carrier containing, discloses a skin care composition.

[0007] Also, WO 2017 / 103083 is a composition for caring for and / or making up keratin materials, in particular comprising at least: - at least one aqueous phase containing a hydrophilic gelling agent, and - at least: - from 3% to 15% by weight of at least one lipophilic gelling agent, based on the total mass of the material, - from 10% to 50% by weight of a filler, based on the total mass of the material, and - from 40% to 85% by weight of at least one fatty phase, based on the total mass of the material a dispersion of at least one anhydrous composite material formed from, and including, a composition is disclosed.

[0008] However, there is still a need for a composition that can provide an improved texture, such as a light / fresh feeling and a reduced greasy feel, to keratin materials and has good stability.
