Problems solved by technology

However, the cleaning action of these compositions on oily stains is not sufficient
In addition, it cannot meet the requirements of being easy to spread evenly on the skin and easily dissolving stains
[0009] In addition, none of the above-mentioned compositions has sufficient cleaning effect on oily stains and water-soluble stains, especially cosmetics that are difficult to come off due to sweat, tears, and meals, such as long-lasting mascara, lipstick, foundation, etc. In terms of cleaning performance not enough

Embodiment 1～16

[0054] Skin cleanser compositions having the compositions shown in Table 1 were produced, and the cleansing performance and ease of rinsing of oil-based mascara and water-based mascara were evaluated. The results are shown in Table 1 together. In addition, the viscosity at 25°C of the oily components used in the examples is also described.

[0055] method

[0056] The skin cleanser composition is prepared by directly using liquid raw materials at normal temperature, dissolving solid raw materials at normal temperature at one time, and then uniformly mixing all the ingredients.

[0057] By observing the appearance of the prepared skin cleanser composition, it can be seen that any composition is an isotropic single liquid phase. A composition having a bicontinuous structure can be confirmed by measuring the self-diffusion coefficient by NMR or the like.

Embodiment 17、 comparative example 1～16

[0071] Skin cleanser compositions with the compositions shown in Table 2 and Table 3 were produced in the same manner as in Example 1, and the cleansing performance and ease of rinsing of oil-based mascara and water-based mascara were evaluated. In addition, the phase state of the prepared skin cleanser composition was confirmed by observing the appearance and measuring the self-diffusion coefficient by NMR. The results are shown in Table 2 and Table 3 together.

Abstract

The present invention relates to a skin cleansing composition comprising (A) an oil component, (B) a hydrophilic nonionic surfactant, (C) a lipophilic amphiphile, (D) a water soluble solvent and (E) water. The composition has an isotropic liquid phase exhibiting a bicontinuous structure. The composition exhibits excellent detergency for the removal of both oil stains and water soluble stains and has high rinsability.

Description

technical field [0001] The present invention relates to skin cleanser compositions. Background technique [0002] As cleansing cosmetics, it can be used in emulsified, soluble, liquid crystal, and other formulations by using a combination of a composition containing oil for exfoliating cosmetics and various surfactants. Among them, especially soluble cleansing cosmetics are easy to spread evenly and combine with stains. [0003] The soluble type includes a dosage form in which the oil phase is soluble in the water phase, a dosage form in which the water is soluble in the oil phase, and a dosage form in which both the oil phase and the water phase form a continuous phase. Since the water phase in the formulation in which the oil phase is soluble in the water phase is a continuous phase, it has a high cleaning effect on water-soluble stains such as salts or water-soluble polymers, and has a high cleaning effect on oil-soluble stains such as wax or liquid oil. insufficient. ...
