Problems solved by technology

However, there are problems in that although it can be mixed uniformly, the appearance is opaque and cloudy, which loses its beauty, and it is easy to drip from hands due to its low viscosity.
Compared with conventional cleansing oils and double-layer cleansing cosmetics, these phases are viscous, but they do not reach a viscosity that does not prevent dripping at all
In addition, the removal effect on waterproof mascara and lipstick cannot be said to be sufficient
Furthermore, its appearance is a composition composed of one layer (oil phase) and does not change, so it may not be sufficiently satisfactory from the viewpoint of appearance.

[0072] Example

[0073] Hereinafter, the present invention will be described in more detail by way of examples, but the present invention is not limited by these descriptions at all. In addition, the compounding quantity represents mass %, unless otherwise stated.

[0074] The compositions of the respective examples were produced according to the formulations shown in the following Tables 1 to 3 by the following method.

[0075] The composition of each example was left to stand, and the appearance was visually observed to evaluate whether the two layers were separated into (A) bicontinuous microemulsion phase and (B) oil phase, the ratio of oil phase, and the state of each layer.

[0076] Next, the composition of each example was vigorously shaken 10 times to evaluate whether it became a single-layer gel, and then it was left to stand again to observe the return to the original two-layer separation state (speed of separation).

Abstract

The purpose of the present invention is to provide a multi-layer cleansing composition which maintains a sufficient cleansing effect as an oil, has a soft texture and easy washability as a gel, and has an attractive appearance. The present invention pertains to a multilayer cleaning composition containing (a) a nonionic surfactant having an HLB of 8-12, (b) an oil component, (c) a humectant, and (d) water, the ratio [(a)/(b)] of the blending amount of the nonionic surfactant (a) to the blending amount of the oil component (b) being in the range of 0.4-0.8, and the multilayer cleaning composition being characterized in that when the composition is left to stand, the amount of the nonionic surfactant (a) is less than the amount of the oil component (b), and the amount of the humectant (c) is less than the amount of the oil component (b). And separating into a plurality of layers containing (A) at least one bicontinuous microemulsion phase and (B) at least one oil phase. The composition reversibly becomes a single-layer gel by oscillation.
