Summary of the Invention

Problem to be Solved by the Invention

[0004] Oily cleansing cosmetics are mainly composed of oily components. Although they have excellent cleaning performance against hard-to-remove makeup cosmetics such as eye makeup and lipstick, they contain a large amount of oily components, so it has been necessary to contain a large amount of surfactant to improve rinsability with water. On the other hand, when a large amount of surfactant is contained, there have been problems such as dry feeling of the skin after rinsing, and a sticky feeling when touching the skin in a wet state after rinsing.

Means for Solving the Problem

[0005] The present inventors have found that by using a combination of a specific oil agent, a specific amount of nonionic surfactant, and an oil gelling agent, an oily cleansing cosmetic can be obtained that achieves both reduction of dry feeling of the skin after rinsing and absence of stickiness as the skin dries after rinsing.

Here, the HLB value refers to the value calculated by Griffin's formula (J,Soc,Cosmet,Chem.,1,311(1949);5,249(1953)). Furthermore, when a mixture of two or more nonionic surfactants is composed of a mixture of surfactants, the HLB of the mixture is determined as follows: The HLB of the mixture is obtained by averaging the HLB values ​​of each nonionic surfactant based on their respective blending ratios. Mixed HLB=Σ(HLBx×Wx) / ΣWx HLBx indicates the HLB value of the nonionic surfactant X. Wx represents the mass (g) of the nonionic surfactant X having an HLBx value.

[0038] Examples 1-8, Comparative Example 1 Oily liquid cleansing cosmetics with the composition shown in Table 1 were manufactured, and their cleansing power against eyeliner, cleansing power against foundation, dryness of the skin after rinsing, and non-greasy feeling when the skin was touched while wet after rinsing were evaluated. The results are also shown in Table 1.

[0039] (Manufacturing method) (1) Components (A) and (C) were uniformly mixed at 25°C. (2) The mixture obtained in (1) was heated to 80°C, components (B) and (D) were added, and the mixture was homogenized. (3) The mixture obtained in (2) was cooled to 25°C while stirring, and degassed to obtain an oily liquid cleansing cosmetic.

[0040] (Evaluation method) (1) Cleansing power for eyeliner: An eyeliner (gel eyeliner, manufactured by Kanebo) measuring 4 cm in length and 0.2 cm in width was applied to a Bio Skin Plate (product number P001-001WHITE, manufactured by Beaulux Co., Ltd.) and allowed to dry for 1 hour. 1 mL of each oil-based liquid cleansing cosmetic was applied to the eyeliner, massaged in with constant pressure for 30 seconds, and then rinsed with running water. The degree to which the eyeliner was removed was visually evaluated on the following 5-point scale. The evaluation was performed by one person. 5: Very good. 4: Good. 3: Fairly good. 2: Defective. 1: Clearly defective.

[0041] (2) Cleansing power against foundation: A 4cm long, 1cm wide area of ​​foundation (Lunasol Light Spread Creamy Liquid, Kanebo Corporation) was applied to a Bio Skin Plate (product number P001-001WHITE, manufactured by Bealux Co., Ltd.) and allowed to dry for 1 hour. 1mL of each oil-based liquid cleansing cosmetic was applied to the foundation, massaged in with even pressure for 30 seconds, and then rinsed with running water. The degree to which the foundation was removed was visually evaluated on a 5-point scale. The evaluation was performed by one person. 5: Very good. 4: Good. 3: Fairly good. 2: Defective. 1: Clearly defective.

[0042] (3) Dryness of the skin after rinsing: Three cosmetic evaluation panelists applied 1 mL of each oil-based liquid cleansing cosmetic to the back of their hands, massaged it in, and then rinsed it off with water. They then evaluated the dryness of the skin on a 5-point scale based on the following criteria. The results are shown as the total score from the three panelists. 5: There is clearly no feeling of dryness. 4: It doesn't feel dry. 3: It doesn't feel very dry. 2: It feels slightly dry. 1: There is a noticeable feeling of dryness.

[0043] (4) The non-slippery feeling when touching wet skin after rinsing: Three cosmetic evaluation panelists applied 1 mL of each oil-based liquid cleansing cosmetic to the back of their hands, massaged it in, and then rinsed it off with water. They then evaluated the non-greasy feeling of the wet skin after rinsing, using a 5-point scale based on the following criteria. The results are shown as the total score from the three panelists. Furthermore, the non-greasy feeling on the skin as it dries after rinsing refers to the feeling that no oily residue of the cleansing cosmetic remains when you rinse off the oily liquid cleansing cosmetic from the back of your hand with running water, stop the water, and then rub the wet back of your hand with the fingers of your other hand. 5: It's clearly not slimy. 4: It doesn't get slimy. 3: It's hardly slimy at all. 2: Slightly slimy. 1: It's clearly slimy.
