Component C is a nonionic surfactant with an HLB value of 2 to 6. A nonionic surfactant with an HLB value of 6 or less is a nonionic surfactant with low hydrophilicity and high lipophilicity. When such a nonionic surfactant is blended into an oil-based solid cleansing cosmetic, even if you try to wash it off with water or lukewarm water after cleansing, it is difficult to wash it off due to its low affinity with water. There is a problem in that it takes time until the slimy feeling of the cosmetic is no longer felt. For this reason, the combination of nonionic surfactants with low HLB values in oil-based solid cleansing cosmetics is generally avoided. However, by using specific amounts of component C and water in combination with the charcoal powder, the above-mentioned problems can be avoided and the agglomeration and sedimentation of the charcoal powder can be suppressed.

The HLB value of component C is 2 to 6, preferably 2 to 5, more preferably 2 to 4. When the HLB value is within the above range, agglomeration and sedimentation of the charcoal powder can be effectively suppressed.

Among these, polyglyceryl-2 triisostearate is preferred because it can suppress agglomeration and sedimentation of charcoal powder without impairing the feeling of use, such as the residual feeling when washed away.

The content of component C in the oil-based solid cleansing cosmetic composition of the present invention is 0.01 to 5.0% by mass, preferably 0.01 to 4.0% by mass. When the content is 0.01% by mass or more, agglomeration and sedimentation of the charcoal powder can be suppressed. Further, when the content is 5.0% by mass or less, agglomeration and sedimentation of the charcoal powder can be suppressed without impairing the residual feeling when washing away. The above content of component C is the total content of all components C in the oil-based solid cleansing cosmetic composition of the present invention.

[Component D]
Component D is a nonionic surfactant with an HLB value of 8 to 15. By using component D, it is possible to obtain an oil-based solid cleansing cosmetic that has excellent makeup compatibility during use and has a low residual feeling when washed off. Note that the HLB value in this specification can be calculated by the Griffin method.

The HLB value of component D is 8 to 15, preferably 8 to 14, more preferably 8 to 13. When the above HLB value is within the above range, makeup blendability during use and washability are excellent.
