Description

[Technical field]

[0001] The present invention relates to a composition comprising at least one glycolipid and at least one citric acid derivative, preferably a cosmetic composition comprising said composition, more preferably a skin care cosmetic composition comprising said composition. [Background technology]

[0002] Biosurfactants such as glycolipids are known to have unique biological activities such as anti-inflammatory efficacy, anti-allergic efficacy, antibacterial efficacy, etc. For example, glycolipids are known to have anti-inflammatory efficacy and are potentially used on keratinous materials such as skin.

[0003] For example, JP-A-2021-6509 discloses a composition comprising (a) at least one biosurfactant and (b) at least one carboxybetaine polymer, the composition being intended for use as a cosmetic composition.

[0004] Furthermore, WO2021 / 180621 discloses a composition comprising 0.2% by mass to 70% by mass, preferably 0.4% by mass to 55% by mass, of at least one glycolipid, 0.01% by mass to 14% by mass, preferably 0.02% by mass to 11% by mass of triethyl citrate, and water (mass percentages refer to the total composition), wherein the mass ratio of the total glycolipids to the total triethyl citrate contained in the composition is in the range of 5:1 to 20:1, preferably 6:1 to 15:1, and particularly preferably 7:1 to 12:1.

[0005] Although glycolipids have some unique biological activities, they have the problem of producing a sticky feeling during application when a formulation contains certain amounts of glycolipids.

[0006] Therefore, there is a need to provide compositions containing glycolipids that exhibit good texture and application properties. [Prior art documents] [Patent documents]

[0170] The present invention will now be described in more detail by examples, which should not be construed as limiting the scope of the present invention.

[0171] (Example 1 and Comparative Examples 1 and 2) The homogeneous solution compositions according to Example 1 and Comparative Examples 1 and 2 were prepared by mixing the components listed in Table 1 using a magnetic stirrer. All values ​​for the amounts of components shown in Table 1 are based on the "mass %" of the active ingredient. Sophorolipid was obtained from BASF (trade name: BioToLife).

[0172] [evaluation] (viscosity) The viscosity of each of the compositions according to Example 1 and Comparative Examples 1 and 2 was measured at room temperature by VISCOMAN™ (GILSON Technology). The bulk viscosity (mPa·S) was automatically calculated from the suction force required in a small pipette (10 μL). The viscosity was measured three times, and the average data was used. For samples with phase separation, they were thoroughly mixed and homogenized before measurement.

[0173] (Sensory evaluation) Four expert panelists evaluated the sensory aspects of "spreadability" and "stickiness" of each of the compositions according to the embodiment and comparative examples 1 and 2 by applying 0.1 mL of each sample to the skin of the panelists. The samples were scored according to the following criteria, and then the scores were averaged. Comparative example 1, which contains only water and glycolipids, was used as the standard for evaluation.

[0174] - Spreadability 1: Higher ductility than standard 2: Slightly more ductile than standard 3: Same ductility as standard 4: Slightly lower ductility than standard 5: Lower ductility than standard - Sticky 1: Stickiness lower than standard 2: Stickiness slightly lower than standard 3: Stickiness the same as standard 4: Stickiness slightly higher than standard 5: Stickier than standard

[0175] The results are summarized in Table 1 below.

[0176] [Table 2]

[0177] As can be seen in Table 1, the composition according to Example 1, which includes a specific combination of the components (a) glycolipid and (b) citric acid ester and (c) polyhydric alcohol in specific ratio amounts, exhibited a lower viscosity and a higher average score in the sensory evaluation than those of Comparative Examples 1 and 2, which do not include the specific combination of (a) glycolipid and (b) citric acid ester.

[0178] Accordingly, it can be concluded that the composition according to the invention is highly suitable as a cosmetic composition for caring for and / or conditioning keratinous materials, i.e. as a skin care cosmetic composition, since it is able to provide the benefits of the biological activity generated by glycolipids on keratinous materials while exhibiting improved texture and application properties.

[0179] (Examples 2 to 6 and Comparative Examples 3 to 8) The homogeneous solution compositions according to Examples 2-6 and Comparative Examples 3-8 were prepared by mixing the ingredients listed in Table 2 using a magnetic stirrer. All values ​​for the amounts of ingredients shown in Table 2 are based on the "mass %" of the active ingredient. Rhamnolipid was obtained from EVONIK (trade name: RHEANCE One).

[0180] [evaluation] (viscosity) The viscosity of each of the compositions according to Examples 2 to 6 and Comparative Examples 3 to 8 was measured at room temperature by VISCOMAN™ (GILSON Technology). The bulk viscosity (mPa·S) was automatically calculated from the suction force required in a small pipette (10 μL). The viscosity was measured three times, and the average data was used. For samples with phase separation, they were thoroughly mixed and homogenized before measurement.

[0181] The results are summarized in Table 2 below.

[0182] [Table 3]

[0183] As can be seen in Table 2, the compositions according to Examples 2 to 6, which contain specific combinations of the components (a) glycolipid, (b) citrate ester, and (c) polyhydric alcohol in specific ratio amounts, exhibited lower viscosities than those corresponding to the Comparative Examples.

[0184] In particular, comparing Example 2 with Comparative Examples 3 and 4, the composition according to Example 2, which contains 60% by weight of triethyl citrate and pentylene glycol in total, exhibited a lower viscosity than Comparative Example 3, which contains 60% by weight of triethyl citrate but no pentylene glycol, and Comparative Example 4, which contains 60% by weight of pentylene glycol but no triethyl citrate, although the total amounts of citric acid ester and polyhydric alcohol are the same. The same results can be derived from the comparisons between Example 3 and Comparative Examples 3 and 5, between Example 4 and Comparative Examples 3 and 6, between Example 5 and Comparative Example 7, and between Example 6 and Comparative Example 8.

[0185] These results show that the combination of (b) citric acid ester and (c) polyhydric alcohol has the effect of reducing the viscosity of the composition containing (a) glycolipid, and thus improving the application properties of the composition according to the present invention. Although the evaluation results of the sensory aspects of "spreadability" and "stickiness" are not disclosed, the compositions according to Comparative Examples 3 to 8 do not show improved "spreadability" and "stickiness" properties because they do not contain a combination of (b) citric acid ester and (c) polyhydric alcohol.

[0186] Example 7 A homogeneous solution composition according to Example 7 having a cosmetically preferred formulation was also prepared by mixing the ingredients shown in Table 3 below. After thoroughly mixing all other ingredients, citric acid was added. All values ​​for the amounts of ingredients shown in Table 3 are based on the "mass %" of the active ingredient. Rhamnolipid was obtained from EVONIK (trade name: RHEANCE One).

[0187] [Table 4]

[0188] The composition according to Example 7 also exhibits good texture and application properties and is therefore highly suitable as a cosmetic composition for caring for and / or conditioning keratinous materials, i.e. as a skin care cosmetic composition.
