[0203] As a volatile solvent, light liquid isoparaffin was mixed in an amount of 50 parts by mass with respect to 100 parts by mass of the sum of the above-described components 1 to 16.

[0204] The details of the above-described components are similar to those already mentioned above.

[0205] <Production Method>

[0206] Components 7 to 16 were uniformly dispersed with a Henschel mixer, and mixture I was obtained. Components 1 to 6 were heated to 70 C. and uniformly dispersed, and mixture II was obtained. While mixture I was stirred with a Henschel mixer, mixture II was added thereto, the mixture was uniformly dispersed, and a cosmetic base material was obtained. To 100 parts by mass of this cosmetic base material, 50 parts by mass of light liquid isoparafilm was added as a volatile solvent, the mixture was kneaded with a kneading machine, and thereby a slurry was obtained. The slurry thus obtained was charged into a metal tray and was compression-molded, and then the solvent was removed by drying the slurry. Thereby, a sample of a foundation was produced.

[0207] <Evaluation>

[0208] The sample of foundation thus obtained was subjected to evaluations similar to those described above, and it was verified that the sample was evaluated as A for the items of Absence of powder flying, Picking up by applicator, Absence of caking, Feeling of use (spreading, adherence, good skin compatibility), Good color development, Formability, and Drop resistance.

[0210] As a volatile solvent, light liquid isoparaffin was mixed in an amount of 40 parts by mass with respect to 100 parts by mass of the SUM of the above-described components 1 to 12.

[0211] The details of the above-described components are similar to those already mentioned above.

[0212] <Production Method>

[0213] Components 6 to 12 were uniformly dispersed with a Henschel Mixer, and mixture I was obtained. Components 1 to 5 were heated to 70 C. and uniformly dispersed, and mixture II was obtained. While mixture I was stirred with a Henschel Mixer, mixture II was added thereto, the mixture was uniformly dispersed, and a cosmetic base material was obtained. To 100 parts by mass of this cosmetic base material, 40 parts by mass of light liquid isoparaffin was added as a volatile solvent, the mixture was kneaded with a kneading machine, and thereby a slurry was obtained. The slurry thus obtained was charged into a metal tray and was compression-molded, and then the solvent was removed by drying the slurry. Thereby, a sample of an eyebrow pencil was produced.

[0217] The details of the above-described components are similar to those already mentioned above.

[0218] <Production Method>

[0219] Components 6 to 12 were uniformly dispersed with a Henschel Mixer, and mixture I of powder components was obtained. Components 1 to 5 were heated to 70 C. and uniformly dispersed, and mixture TI of oily components was obtained. While mixture I was stirred with a Henschel Mixer, mixture II was added thereto, and the mixture was uniformly dispersed. This dispersion was charged into a metal tray and was compression-molded, and thereby a sample of a blusher was produced.
