KIT FOR CARING FOR KERATIN MATERIALSTECHNICAL FIELD
[0001] The present invention relates to a kit, preferably for caring for keratin materials. The present invention also relates to a non-therapeutic process for caring for keratin materials.BACKGROUND ART
[0002] Among all the compositions for caring for keratin materials, in particular the skin, masks are known to have high penetration efficacy on the keratin materials.
[0003] In the market, gel-type masks are popular due to their moisture effect and affinity to the skin.
[0004] However, gel-type masks generally face the difficulty in production since it is difficult for the gels to be filled into sachets due to the high viscosity of the gels.
[0005] Efforts have been made to produce gel-type masks comprising gels with low viscosity. However, it has been found that there is dripping issue for gel-type masks comprising gel with low viscosity. When such masks are taken out from sachets, the gel will drip from the mask substrate very quickly, which is unpleasant.
[0006] Therefore, it will be desired to provide gel-type masks without difficulty in production and without dripping issue.SUMMARY OF THE INVENTION
[0007] An object of the present invention is to provide gel-type masks without difficulty in production and without dripping issue.

[0010] A) a first container comprising a substrate and an aqueous composition comprising at least one carboxyvinyl polymer; and
[0011] B) a second container comprising an oily composition comprising at least one ion activator.
[0012] The inventors found that the kit according to the present invention can be easily prepared, gel-type mask without dripping issue can be formed from the kit according to the present invention.
[0013] The kit according to the present invention is suitable for being used as a mask, especially the one for caring for keratin materials.
[0014] According to a second aspect, the present invention provides a non-therapeutic process for caring for keratin materials with the kit according to the present invention, comprising:
[0015] a) mixing the oily composition and the aqueous composition to form a mixed system on the substrate; and
[0016] b) applying the substrate with the mixed system on the keratin materials.
