[0004] However, a good penetrating feeling and a rich feeling are often incompatible with each other. In other words, it is difficult for a cosmetic product having a good penetrating feeling to provide a rich feeling, and it is difficult for a cosmetic product having a rich feeling to provide a good penetrating feeling. Therefore, it is not easy for a cosmetic product to provide an excellent texture, with both a good penetrating feeling and a rich feeling.

The melting point of the wax can be measured using a differential scanning calorimeter (DSC), for example the calorimeter sold under the name MDSC 2920 by TA Instruments or the calorimeter sold under the name DSC Q100 by TA Instruments with the TA universal analysis software.
[0073] The measurement protocol is as follows:
[0074] A 5 mg sample of wax placed in a crucible is subjected to a first temperature ramp going from -20°C to 100°C, at a heating rate of 10°C / minute, it is then cooled from 100°C to -20°C at a cooling rate of 10°C / minute and is finally subjected to a second temperature ramp going from -20°C to 100°C at a heating rate of 5°C / minute. During the second temperature ramp, the variation in the difference in power absorbed by the empty crucible and by the crucible containing the wax sample is measured as a function of temperature. The melting point of the compound is the temperature value corresponding to the top of the peak of the curve representing the variation in the difference in power absorbed as a function of temperature.

[0221] The additional wax is different from the (b) jojoba ester wax explained above.
[0222] For the purposes of the present invention, the term "wax" denotes a deformable or non-deformable lipophilic compound, which is solid at room temperature (25°C), with a reversible solid-liquid change of state, having a melting point greater than or equal to 30°C, which may range up to 120°C. In particular, waxes suitable for use in the present invention may have a melting point greater than or equal to 60°C and in particular greater than or equal to 70°C.
[0223] The expression “lipophilic compound” designates a compound having an acid number and a hydroxyl number of less than 150 mg KOH / g.
[0224] For the purposes of the present invention, the melting point corresponds to the temperature of the most endothermic peak observed on the thermal analysis (DSC) as described in the ISO 11357-3; 1999 standard. The melting point of the wax can be measured using a differential scanning calorimeter (DSC), for example the calorimeter sold under the name MDSC 2920 by TA Instruments or the calorimeter sold under the name DSC Q100 by TA Instruments with the TA universal analysis software.
[0225] The measurement protocol is as follows:
[0226] A 5 mg sample of wax placed in a crucible is subjected to a first temperature ramp going from -20°C to 100°C, at a heating rate of 10°C / minute, it is then cooled from 100°C to -20°C at a cooling rate of 10°C / minute and is finally subjected to a second temperature ramp going from -20°C to 100°C at a heating rate of 5°C / minute. During the second temperature ramp, the variation of the difference in power absorbed by the empty crucible and by the crucible containing the wax sample is measured as a function of temperature. The melting point of the compound is the temperature value corresponding to the top of the peak of the curve representing the variation of the difference in absorbed power as a function of temperature.
[0227] The additional waxes may be hydrocarbon waxes, silicone waxes and / or fluoro waxes, and may be of vegetable, animal, mineral and / or synthetic origin.

[0285] Table 1 [Evaluations] (Sensation of penetration)
[0286] Five professional panelists evaluated the "penetration sensation" after application of the compositions according to Example 1 and Comparative Examples 1 to 3. Each panelist took each composition and applied it to his or her face to evaluate the penetration sensation during application, and rated it from 1 (poor) to 5 (very good), and it was then classified into the following 4 categories based on the average of the rating:
[0287] Very good: From 5.0 to 4.0 (the sensation of penetration is felt during application)
[0288] Good: From 3.9 to 3.0 (the sensation of penetration is felt slightly during application)
[0289] Bad: From 2.9 to 2.0 (a weak sensation of penetration is felt during application)
[0290] Very poor: From 1.9 to 1.0 (the sensation of penetration is not felt during application)
[0291] The results are shown in Table 1. (Rich feeling)
[0292] Five professional panelists evaluated the “rich feeling” after application of the compositions according to Example 1 and Comparative Examples 1 to 3. Each panelist took each composition and applied it to their face to evaluate the rich feeling (rich texture) after application, and rated it from 1 (poor) to 5 (very good), and it was then classified into the following 4 categories based on the average of the rating:
[0293] Very good: From 5.0 to 4.0 (richness is felt after application)
[0294] Good: From 3.9 to 3.0 (richness is slightly felt after application)
[0295] Bad: From 2.9 to 2.0 (low richness is felt after application)
[0296] Very poor: From 1.9 to 1.0 (the richness is not felt after application)
[0297] The results are shown in Table 1. (Stability)
[0298] Each of the compositions according to Example 1 and Comparative Examples 1 to 3 was poured into a glass bottle and kept under temperature change conditions at 4°C, 25°C, 40°C and 45°C for 2 months. Each sample was then investigated in terms of degree of change (transparency, color, odor and pH) and was evaluated in accordance with the following criteria:
[0299] Very good: Almost the same conditions as in production.
[0300] Good: Slight changes in transparency, color, odor and pH have were observed. No separation or creamy appearance was observed.
[0301] Bad: Changes in transparency, color, odor, and pH were clearly observed. Separations, creaminess, and crystallizations were also clearly observed.
[0302] Very poor: Changes in transparency, color, odor, and pH were significantly noticed. Separations, creaminess, and crystallizations were significantly noticed.
[0303] The results are shown in Table 1. (Summary)
[0304] As evident from Table 1, the composition according to the present invention (Example 1) was able to provide both a good penetrating sensation and a good rich sensation; and was stable to temperature changes for 2 months, which could be attributed to a combination of ingredients (a), (b), (c) and (d).
[0305] Thus, the composition according to the present invention can provide excellent texture and stability, in particular, for a long period, even in the event of temperature changes.
[0306] Cetearyl alcohol and cetyl alcohol, as ingredients (e), in the composition according to Example 1 can be considered negligible, since they are simple fatty substances.
[0307] The Helianthus annuus seed wax (sunflower / helianthus annuus seed cera) in the composition according to Example 1 can also be considered negligible, since these are simple fatty substances.
[0308] Furthermore, polyglycerin-3 and tocopherol in the composition according to Example 1 can be considered negligible, since the amount of each of these ingredients is very small.
[0309] In contrast, the compositions according to Comparative Examples 1 and 3 which did not include ingredient (a) showed poor sensation of penetration at touch as well as instability.
[0310] The composition according to Comparative Example 2 which did not include ingredients (b) and (c) showed inferior texture in terms of rich feel, as well as instability.
