Description

Title of the invention: STABLE NON-STICKY COMPOSITION WITH TEXTURE TRANSFORMATION PROPERTY Technical field

[0001] The present invention relates to a composition, preferably a cosmetic composition, and more preferably a cosmetic composition for the skin which is stable and which can provide a transformation of texture as well as a non-stickiness. STATE OF THE ART

[0002] Providing a comfortable texture to the skin is one of the key features of cosmetic products, especially skin care cosmetic products.

[0003] In particular, texture transformation (texture change, for example, from a gel or cream to a liquid, which corresponds to the change in physical properties of a composition, such as a collapse of the structure of the composition which could allow the liquid to flow out of the composition) which could provide a refreshing sensation at the beginning of application, as well as a non-sticky sensation or a reduced sticky sensation after application, are always necessary for consumer satisfaction during use.

[0004] It should be noted that a composition which is unstable and easily causes collapse of the structure of the composition often provides a comfortable feeling during use. This means that it is difficult to provide both a comfortable feeling during use and good stability.

[0005] So far, several technologies relating to gel-like compositions or emulsion compositions that provide improved texture and stability have been reported. For example, WO2022 / 124385 discloses a stable composition that can provide texture transformation. DISCLOSURE OF THE INVENTION

[0006] However, sufficient studies have not yet been conducted regarding stable compositions that can provide no or reduced stickiness after application, in addition to texture transformation during application.

[0007] An objective of the present invention is to provide a stable composition which can provide no or reduced stickiness after application, in addition to texture transformation during application.

[0020] The (c) fatty acid polyglyceryl ester having at least one hydroxyl group in its polyglyceryl moiety may be selected from polyglyceryl polyricinoleates, fatty acid polyglyceryl esters derived from two or more fatty acids, and mixtures thereof.

[0021] The (c) fatty acid polyglyceryl ester having at least one hydroxyl group in its polyglyceryl moiety may be selected from the group consisting of polyglyceryl-6 polyricinoleate, polyglyceryl-4 diisostearate / polyhydroxystearate / sebacate, and a mixture thereof.

[0028] After careful research, the inventors have discovered a novel approach to providing a stable composition that can provide no or reduced stickiness after application, in addition to texture transformation during application.

[0029] Thus, one aspect of the present invention is a composition, comprising:

[0030] (a) at least one amphiphilic polymer comprising at least one hydrophilic unit and at least one hydrophobic motif;

[0031] (b) at least one polysaccharide derived from microorganisms; and

[0034] the (c) fatty acid polyglyceryl ester having at least one hydroxyl group in the polyglyceryl moiety has an HLB value of 7.0 or less, preferably 6.5 or less, and more preferably 6.0 or less.

[0035] The composition according to the present invention is stable and can provide no or reduced stickiness after application, in addition to texture transformation during application.

[0036] The composition according to the present invention is stable immediately after the preparation of the composition and for a long time after the preparation of the composition, even in case of temperature changes from a cold temperature to a hot temperature. Therefore, the composition according to the present invention is stable in the time and can be stored for a long time even during temperature changes occurring between winter and summer.

[0037] The composition according to the present invention can provide no or reduced stickiness, preferably after application.

[0038] The term "sticky" here means a property that provides a sticky sensation to the skin.

[0304] [Evaluations]

[0305] (Viscosity)

[0306] The viscosity of each of the compositions according to Examples 1 and 2 and Comparative Examples 1 to 4 was measured at room temperature (25°C) with a type B viscometer under the rotor conditions: No. 4, rotation speed: 6 rpm, and measurement time: 1 minute.

[0307] The results are shown in Table 1.

[0308] (Texture Transformation)

[0309] Five professional panelists evaluated the “texture transformation” during the application of the compositions according to Examples 1 and 2 and Comparative Examples 1 to 4. Each panelist took each composition and applied it in a circular manner to their face. The panelists evaluated the moment when the texture transformation (from cream to liquid) occurred and rated it from 1 (poor) to 5 (very good), which was then classified into the following 4 categories based on the average of the rating:

[0310] Very good: From 5.0 to 4.0 (texture transformation is clearly felt at the beginning of the application)

[0311] Good: From 3.9 to 3.0 (texture transformation is felt at the beginning of the application)

[0312] Bad: From 2.9 to 2.0 (texture transformation is barely noticeable at the beginning of the application)

[0313] Very bad: From 1.9 to 1.0 (texture transformation is not felt at all at the beginning of the application)

[0314] The results are shown in Table 1.

[0315] (Non-sticky feeling)

[0316] Five professional panelists evaluated the "non-sticky feeling" after applying the compositions according to Examples 1 and 2 and Comparative Examples 1 to 4. Each panelist took each composition and applied it to their face to evaluate the non-sticky feeling 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:

[0317] Very good: From 5.0 to 4.0 (the stickiness is not felt at all after application)

[0318] Good: From 3.9 to 3.0 (the stickiness is barely felt after application)

[0319] Bad: From 2.9 to 2.0 (stickiness is felt after application)

[0320] Very poor: From 1.9 to 1.0 (the stickiness is clearly felt after application)

[0321] The results are shown in Table 1.

[0322] (Stability)

[0323] Each of the compositions according to Examples 1 and 2 and Comparative Examples 1 to 4 was poured into a glass bottle and kept under temperature change conditions at 4°C, 25°C, 37°C and 45°C for 2 months. Each sample was then investigated in terms of degree of change (appearance, color and odor) and was evaluated in accordance with the following criteria:

[0324] Very good: Almost the same conditions as in production.

[0325] Good: Few changes in appearance, color, and odor were observed.

[0326] Bad: Changes in appearance, color, and odor have been clearly observed.

[0327] Very bad: Changes in appearance, color and odor have been significantly noticed.

[0328] The results are shown in Table 1.

[0329] (Summary)

[0330] As is evident from Table 1, the composition according to the present invention (Examples 1 and 2) was able to provide excellent cosmetic effects in terms of texture transformation; non-sticky feeling; and stability in case of temperature changes for 2 months, which could be attributed to a combination of ingredients (a) to (c). Thus, the composition according to the present invention can provide, in particular, excellent hand feeling and stability for a long time, even in the event of temperature changes.

[0331] The composition according to Example 2 is more preferable than the composition according to Example 1, due to the presence of ingredient (d) (filler), in terms of non-sticky feeling after application.

[0332] Furthermore, the composition according to Comparative Example 1 which did not include ingredient (a) (amphiphilic polymer comprising at least one hydrophilic unit and at least one hydrophobic unit) showed inferior texture transformation, as well as instability. In addition, the viscosity of the composition according to Comparative Example 1 could not be measured due to phase separation.

[0333] The composition according to Comparative Example 2 which did not include ingredient (b) (microorganism-derived polysaccharide) showed inferior texture transformation, as well as instability.

[0334] The composition according to Comparative Example 3 which did not include ingredient (c) (a low HLB fatty acid polyglyceryl ester having at least one hydroxyl group in its polyglyceryl moiety) showed inferior texture transformation.

[0335] The composition according to Comparative Example 4 which did not include ingredient (c) but included a high HLB fatty acid polyglyceryl ester having at least one hydroxyl group in its polyglyceryl moiety showed inferior texture transformation.
