[0185]

Chemical formula

[0186] It is understood that PEG represents the CH2CH2O group and "cocoyl" represents the residue of coconut fatty acid.

[0187] This surfactant has a molecular structure very similar to that of ceramide-3.

[0188] Preferably, the gemini surfactant of formula (I) is, in a mixture with other surfactants, especially (a) an ester of a C6-C 22 fatty acid (preferably C 14 -C 20 , for example, stearic acid) and glyceryl, (b) a C6-C 22 fatty acid (preferably C 14 -C 20, for example stearic acid) and diesters of citric acid and glycerol (especially C6-C 22 fatty acid esters and glyceryl monocitrates), and (c) C 10 -C 30 It can be used in a mixture with an aliphatic alcohol (preferably behenyl alcohol).

[0189] Advantageously, the composition according to the invention comprises a mixture of dicocoylethylenediamine PEG-15 sodium sulfate, glyceryl stearate, glyceryl stearate monocitrate and behenyl alcohol.

[0190] For example, the gemini surfactant of formula (I) can be used as a mixture with other surfactants, for example in the form of products sold by Sasol under the trade name Ceralution®: Ceralution® H: behenyl alcohol, glyceryl stearate, glyceryl stearate citrate and dicocoylethylenediamine PEG-15 sodium sulfate (INCI name), Ceralution® F: sodium lauroyl lactylate and dicocoylethylenediamine PEG-15 sodium sulfate (INCI name), and Ceralution® C: water, capric / caprylic triglyceride, glycerin, cetearyl ethoxylate-25, dicocoylethylenediamine PEG-15 sodium sulfate, sodium lauroyl lactylate, behenyl alcohol, glyceryl stearate, glyceryl stearate citrate, gum arabic, xanthan gum, phenoxyethanol, methylparaben, ethylparaben, butylparaben, isobutylparaben (INCI name).

[0191] The gemini surfactant of formula (I) can correspond to 3% to 50% by mass of the above mixture. Preferably, the composition according to the present invention may contain, as the gemini surfactant of formula (I), raw materials of INCI name: behenyl alcohol, glyceryl stearate, glyceryl stearate citrate, and disodium cocoyl ethylenediamine PEG-15 sulfate, which are sold by Sasol under the trade name Ceralution® H.

[0196] The additional wax is different from the (b) jojoba ester wax described above.

[0197] For the purposes of the present invention, the term "wax" means a lipophilic compound which is solid at room temperature (25 °C), whose state changes reversibly between solid / liquid, which has a melting point of 30 °C or higher and may be up to 120 °C, and which may be deformable or non-deformable. In particular, the waxes suitable for use in the present invention may have a melting point of 60 °C or higher, particularly 70 °C or higher.

[0198] The term "lipophilic compound" refers to a compound having an acid value and a hydroxyl value of less than 150 mg KOH / g.

[0199] For the purposes of the present invention, the melting point corresponds to the temperature of the maximum endothermic peak observed by thermal analysis (DSC), as described in ISO standard 11357-3; 1999. The melting point of the wax can be measured using a differential scanning calorimeter (DSC), for example a calorimeter sold under the name MDSC 2920 by TA Instruments, or a calorimeter sold under the name DSC Q100 by TA Instruments, using TA Universal Analysis software.

[0200] The measurement protocol is as follows. A 5 mg sample of the wax placed in a crucible is subjected to a first temperature increase from -20 °C to 100 °C at a heating rate of 10 °C / min, then cooled from 100 °C to -20 °C at a cooling rate of 10 °C / min, and finally subjected to a second temperature increase from -20 °C to 100 °C at a heating rate of 5 °C / min. During the second temperature increase, the variation in the difference between the amount of electrical power absorbed by the empty crucible and the amount of electrical power absorbed 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 peak of the curve representing the variation in the difference in the amount of electrical power absorbed as a function of temperature.

[0201] The additional wax may be a hydrocarbon wax, a silicone wax and / or a fluorowax, and may be of plant, animal, mineral and / or synthetic origin.

Table 2A

[0242]

Table 2B

[0243] [Evaluation] (Penetration feeling) Five professional sensory testers evaluated the "penetration feeling" after applying the compositions according to Example 1 and Comparative Examples 1 - 3. Each sensory tester took each composition, applied it to their own face, evaluated the penetration feeling during application, rated it from 1 (extremely poor) to 5 (extremely good), and then classified it into the following four categories based on the average of the ratings. Extremely good: 5.0 - 4.0 (Penetration feeling is felt during application) Good: 3.9 - 3.0 (Some penetration feeling is felt during application) Poor: 2.9 - 2.0 (Almost no penetration feeling is felt during application) Extremely poor: 1.9 - 1.0 (No sense of penetration during coating)

[0244] The results are shown in Table 1.

[0245] (Rich feel) Five professional sensory testers evaluated the "rich feel" after applying the compositions according to Example 1 and Comparative Examples 1 - 3. Each sensory tester took each composition, applied it to their face, evaluated the rich feel (rich texture) after application, rated it from 1 (extremely poor) to 5 (extremely good), and then classified it into the following four categories based on the average of the ratings. Extremely good: 5.0 - 4.0 (Richness is felt after application) Good: 3.9 - 3.0 (Some richness is felt after application) Poor: 2.9 - 2.0 (Almost no richness is felt after application) Extremely poor: 1.9 - 1.0 (No richness is felt after application)

[0246] The results are shown in Table 1.

[0247] (Stability) Each composition according to Example 1 and Comparative Examples 1 - 3 was filled into glass bottles and kept for 2 months under temperature change conditions of 4°C, 25°C, 40°C, and 45°C. Then, each sample was inspected for the degree of change (transparency, color, odor, and pH) and evaluated according to the following criteria. Extremely good: Almost the same state as at the time of manufacture. Good: Almost no change in transparency, color, odor, and pH was observed. No separation, creaming, or change in appearance was observed either. Poor: Changes in transparency, color, odor, and pH were clearly observed. Separation, creaming, and crystallization were also clearly observed. Extremely poor: Changes in transparency, color, odor, and pH were significantly observed. Separation, creaming, and crystallization were significantly observed.

[0248] The results are shown in Table 1.

[0249] (Abstract) As is clear from Table 1, the composition according to the present invention (Example 1) was able to provide both a good sense of penetration and a rich feel, and was stable under temperature changes for two months, which may be due to the combination of components (a), (b), (c) and (d).

[0250] Therefore, the composition according to the present invention can provide an excellent texture and, in particular, long-term stability even under temperature changes.

[0251] Cetearyl alcohol and cetyl alcohol as component (e) in the composition according to Example 1 can be considered non-essential since they are merely fatty substances.

[0252] Sunflower seed wax / sunflower seed cerin in the composition according to Example 1 can also be considered non-essential since they are merely fatty substances.

[0253] Also, polyglycerin-3 and tocopherol in the composition according to Example 1 can be considered non-essential since the amount of each of these components is very small.

[0254] On the other hand, the compositions according to Comparative Examples 1 and 3 that do not contain component (a) showed a poor touch in terms of permeability and instability.

[0255] The composition according to Comparative Example 2 that does not contain components (b) and (c) showed a texture inferior in terms of a rich feel and instability.
