(17) <Production of Oil Wax Mixtures>

(18) Specifically, the component (A) and the component (A′), and the component (B) and the component (B′) were heated to 100° C. and subjected to melting and mixing, and the mixture was then cooled to obtain a solid wax composition. Subsequently, the liquid oil was stirred and mixed with the obtained solid wax composition in a heated state at 100° C., and the resulting mixture was poured into a polycarbonate container (diameter: 38 mm, depth: 17 mm) and then cooled to room temperature, thus producing a circular cylindrical oil wax mixture.

(19) <Hardness Evaluation>

(20) Using a gel hardness meter (product name: SD700, manufactured by Sun Scientific Co., Ltd.), the stress (g) upon pushing a spherical plunger with a diameter of 5 mm 2.5 mm into the oil wax mixture in the polycarbonate container was measured and recorded as the hardness.

(40) These results revealed that the oil wax mixtures of Examples 1 to 11, which contained solid wax compositions containing the candelilla wax of the component (A) and the behenyl behenate of the component (B) in a ratio within a range from 45:55 to 95:5, were satisfactorily hard with a hardness of at least 300 g, and exhibited little oil oozing, regardless of the type of liquid oil used. In particular, based on the fact that even in the oil wax mixtures of Examples 6 to 8, which also included a monoester other than the component (B), favorable hardness and oil oozing resistance of similar levels to those of Examples 1 to 5 which contained only the monoester of the component (B) were able to be achieved, it was evident that the hardness improvement effect and oil oozing suppression effect obtained as a result of adding the component (A) and the component (B) in a ratio within a range from 45:55 to 95:5 was not significantly affected by other components, and should be achievable in cosmetics having all manner of formulations. Further, the results of Examples 12 to 15 confirmed that even when stearyl behenate or hydrogenated jojoba oil was used as the component (B), similar effects to those achieved using behenyl behenate were able to be obtained.

(41) In contrast, in the case of the oil wax mixtures of Comparative Examples 1 and 2 which contained a wax other than the component (A), the level of oil oozing was severe, and particularly in the case of Comparative Example 1 which contained carnauba wax, the hardness was also very low. Furthermore, in the case of the oil wax mixtures of Comparative Examples 3 to 6 which contained an ester other than the component (B), the hardness was very low. Particularly in Comparative Examples 3 to 5, which contained stearyl stearate with the candelilla wax, based on the fact that absolutely no hardness improvement effect was observed, even when the blend amount of stearyl stearate was increased, it was evident that this hardness improvement effect was only obtainable by using a combination of candelilla wax and the specific monoester of the component (B).

(42) Further, the oil wax mixtures of Comparative Examples 7 to 10 in which the blend ratio between the candelilla wax of the component (A) and the behenyl behenate of the component (B) was outside the range from 45:55 to 95:5 also exhibited unsatisfactory hardness. In particular, Comparative Example 8 in which the content ratio between the component (A) and the component (B) was 40:60 had a markedly lower hardness than the oil wax mixture of Example 1 in which the content ratio was 50:50, and Comparative Example 9 in which the content ratio was 95:5 had a markedly lower hardness than the oil wax mixture of Example 5 in which the content ratio was 90:10.

[Example 16, Comparative Examples 11 and 12] Stick-Type Lip Creams

(43) Stick-type lip creams were produced in accordance with the formulations shown in Table 6, and the storage stability and texture were evaluated. The results are shown in Table 6. The numerical values in the component cells in the table represents % by mass values.

(44) <Raw Materials for Stick-Type Lip Creams>

(45) For the raw materials of the stick-type lip creams shown in Table 6, the triethylhexanoin used “T.I.O” manufactured by The Nisshin OilliO Group, Ltd., the diisostearyl malate used “COSMOL 222” manufactured by The Nisshin OilliO Group, Ltd., the polyglyceryl-2 diisostearate used “COSMOL 42V” manufactured by The Nisshin OilliO Group, the polyglyceryl-2 triisostearate used “COSMOL 43V” manufactured by The Nisshin OilliO Group, the hydrogenated polyisobutene used “PARLEAM 18” manufactured by NOF Corporation, the candelilla wax used “Purified Candelilla Wax SR-2” manufactured by Mitsuba Trading Co., Ltd., the behenyl behenate used the material synthesized in Synthesis Example 1, the microcrystalline wax used “MULTIWAX W445” manufactured by Sonneborn LLC, and the paraffin wax used “Paraffin 155” manufactured by Nippon Seiro Co., Ltd.

(46) <Production>

(47) The component (A) and the component (B) shown in Table 6 were heated to 100° C., and following melting and mixing, the mixture was cooled to obtain a solid wax composition. The other components were added to the obtained solid wax composition, and following stirring and mixing in a heated state at 100° C., the resulting mixture was poured into a bullet-shaped lipstick mold and then cooled to room temperature, thus obtaining a stick-type lip cream. For evaluation of the texture, the amount of the wax was adjusted so that the similar hardness might be achieved, and the blend amount of one of the liquid oils was adjusted to make the total amount of components up to 100% by mass.

(48) <Evaluation of Storage Stability>

(49) For each lip cream, the storage stability was evaluated using the change in hardness as an indicator. Specifically, the hardness (a) of the lip cream immediately following production, and the hardness (b) of the lip cream following a cycled storage test in which the steps of storing the lip cream at 5° C. for 12 hours and then storing the lip cream at 40° C. for 12 hours were repeated for two weeks were measured, and the degree of change [(b)/(a)] was determined. A higher value for this degree of change was evaluated as indicating superior storage stability.

(50) <Evaluation of Texture>

(51) Each lip cream was evaluated by five specialist panelists for “resistance to oil oozing”, “adhesion”, “spreadability” and “degree of gloss”, by comparing the lip cream with a commercially available lip cream, and assigning an evaluation of “superior”, “similar” or “inferior” for each category. The results are shown in Table 6.

(52) Evaluation Criteria for Texture:

(53) A: at least three of the five panelists evaluated the lip cream as “superior” to the commercially available lip cream

(54) B: neither A nor C

(55) C: at least three of the five panelists evaluated the lip cream as “inferior” to the commercially available lip cream

(57) The lip cream of Example 16 had satisfactory hardness as a stick-type cosmetic, suffered little oil oozing during use, had a favorable texture, and also exhibited good storage stability. Lip creams tend to suffer a decreases in hardness when subjected to repeated temperature changes, which can sometimes cause the lip stick to break during use, but it was confirmed that the solid oily cosmetic containing the solid wax composition according to the present invention was resistant to deterioration in the hardness during storage, meaning this concern can be minimized.

(59) For the raw materials of the lipstick shown in Table 7, the pentaerythrityl tetraisostearate used “SALACOS 5418V” manufactured by The Nisshin OilliO Group, Ltd., the glyceryl tri(caprylate/tricaprate) used “O.D.O.” manufactured by The Nisshin OilliO Group, Ltd., the hydrogenated polyisobutene used “PARLEAM 18” manufactured by NOF Corporation, the diisostearyl malate used “COSMOL 222” manufactured by The Nisshin OilliO Group, the polyglyceryl-2 triisostearate used “COSMOL 43V” manufactured by The Nisshin OilliO Group, the dipentaerythrityl hexa(hydroxystearate/stearate/rosinate) used “COSMOL 168ARV” manufactured by The Nisshin OilliO Group, the glyceryl (ethylhexanoate/stearate/adipate) used “NOMCORT LAH” manufactured by The Nisshin OilliO Group, the candelilla wax used “Purified Candelilla Wax SR-2” manufactured by Mitsuba Trading Co., Ltd., and the behenyl behenate used the material synthesized in Synthesis Example 1.

(60) <Production>

(61) Of the raw materials shown in Table 7, the candelilla wax and the behenyl behenate were heated to 100° C., and following melting and mixing, the mixture was cooled to obtain a solid wax composition. The other components were added to this solid wax composition, and following thorough mixing under heating at 90° C. to obtain a uniform mixture, the mixture was degassed under reduced pressure, and then poured into a mold. Subsequently, the mixture was cooled to 20° C. to obtain a lipstick (stick-type). In this case, the proportion representing the total mass of the candelilla wax and the behenyl behenate relative to the total mass of the lipstick excluding the powder components (red color No. 201, red color No. 202, and titanated mica) was about 17% by mass.
