[Examples 1-4, Comparative Examples 1-3]
A transparent glass bottle was filled with the composition of any of Production Examples 1, 6, and 7 (oil composition (external phase)) having the blending amount shown in Table 1. Next, a filling nozzle (thin tube) for discharging any of the compositions (inner phase compositions) of Production Examples 2 to 5 and 8 having the blending amounts shown in Table 1 into the oily composition (outer phase) is provided. From the top of the container to the bottom of the container. Next, the inner phase composition was discharged from the nozzle while rotating the container to raise the nozzle to obtain a composition in which the three-dimensional pattern inner phase composition was formed in the outer phase. The evaluation results of the composition are shown in Table 1.

  As is clear from Table 1, all of the compositions of Examples 1 to 4 have a stable spiral pattern formed in the oily composition (external phase), and have a beautiful beauty (aesthetics) and emollient. It turns out that it is a composition excellent in the effect.

  On the other hand, the composition of Comparative Example 1 in which the viscosity of the inner phase is low is inferior in the stability of the spiral pattern, the visual beauty (aesthetics), and the composition of Comparative Example 2 in which the hardness of the outer phase is low. In addition, the composition of Comparative Example 3 is inferior in the stability of the spiral pattern, the visual beauty (aesthetics), the emollient effect, and the hardness of the outer phase is high. ), The emollient effect is inferior, and none of the effects of the present invention can be exhibited.

  The compositions of Examples 1 to 4 are applied to makeup cosmetics such as under makeup and lip gloss, skin care cosmetics such as massage creams, packs, essence creams, and eye creams, and hair care cosmetics such as hair waxes. Application was possible.

Table 2 shows the formulation of the oil-based composition (outer phase) according to the outer phase of Examples 5 to 9 and Table 3 shows the formulation of the inner phase composition according to the inner phase of Examples 5 to 9 and the state of the system. From the components shown in Table 2 and the oily composition (outer phase) obtained from the blending amount, and from the components and the internal phase composition obtained from the blending amounts shown in Tables 3 to 6, the oily composition (outer phase) contains A composition in which the phase composition was dispersed in a three-dimensional pattern was prepared according to the methods of Examples 1 to 4. In addition, the compounding quantity of the internal phase of the Example was as follows in all the compositions. Example 5: 5.0 mass%, Example 6: 15.0 mass%, Example 7: 10.0 mass%, Example 8: 40.0 mass%, Example 9: 1.0 mass%. The evaluation results are shown in Table 7.

In Table 2,
(Note 1) KSG-44 (manufactured by Shin-Etsu Chemical Co., Ltd.) is blended (the blending amount is the blending amount of KSG-44, and the blending amount of (vinyl dimethicone / lauryl dimethicone) cross polymer is 30% by mass in KSG-44. is there.)

  As is apparent from Table 7, all of the compositions of Examples 5 to 9 according to the present invention have a stable spiral pattern formed in the oily composition (external phase), and have a beautiful appearance (aesthetics). ), An emollient effect. In addition, the compositions of Examples 5 to 9 are used for make-up cosmetics such as under makeup and lip gloss, skin care cosmetics such as massage creams, packs, essence creams, and eye creams, and hair care cosmetics such as hair waxes. Application was possible.
