Description

[Technical field]

[0001] The present invention relates to a composition, preferably a cosmetic composition, more preferably a skin cosmetic composition, which is stable and capable of providing texture transformation and non-stickiness. [Background technology]

[0002] Providing a pleasant texture to the skin is one of the main properties of a cosmetic product, in particular a skin care cosmetic product.

[0003] In particular, texture transformation (a change in the physical properties of the composition, e.g. a change in texture from gel or cream to liquid, corresponding to a breakdown in the structure of the composition, whereby the liquid can flow out of the composition), which can provide a fresh sensation at the initial stage of application as well as a non-sticky or reduced sticky feel after application, remains necessary for customer satisfaction during use.

[0004] It should be noted that compositions that are unstable and easily cause the composition's structure to collapse often provide a pleasant feel in use, which means that it is difficult to provide both a pleasant feel in use and good stability at the same time.

[0005] To date, several techniques have been reported for gel-like or emulsion compositions that provide improved texture and stability. For example, WO2022 / 124385 discloses a stable composition that can provide texture transformation. [Prior art documents] [Patent documents]

[0225] The present invention will now be described in further detail by way of examples, which should not be construed as limiting the scope of the present invention.

[0226] (Examples 1 to 2 and Comparative Examples 1 to 4) The following compositions in the form of O / W emulsions according to Examples 1-2 and Comparative Examples 1-4 shown in Table 1 were prepared by mixing the components shown in Table 1 as follows. (1) Mix the ingredients in column A of Table 1 at 75-80°C to form a homogeneous mixture (phase A); (2) Add the ingredients in column B of Table 1 to the homogenous mixture (phase A), followed by homogenization to obtain a homogenous mixture (phases A and B); (3) adding 80% of the ingredients in column C of Table 1 to the homogenous mixture (phases A and B), which are then homogenized to obtain a homogenous mixture (phases A, B and 80% C); (4) Cool the homogenous mixture (phases A, B and 80% C) to room temperature; (5) adding ingredients from column D of Table 1, if present, to the homogenous mixture (phases A, B and 80% C), followed by homogenization to obtain a homogenous mixture (phases A, B, 80% C and D); (6) adding the ingredients in column E of Table 1 to the homogenous mixture (phases A, B, 80% C, and D), followed by homogenization to obtain a homogenous mixture (phases A, B, 80% C, D, and E) having a pH of 6.5; (7) mixing 20% ​​of the components in column C of Table 1, and, if present, the components in column F of Table 1, followed by homogenization to obtain a uniform mixture (20% C and F phase); (8) The homogeneous mixture (20% C and F phases) is gradually added to the homogeneous mixture (A, B, 80% C, D and E phases) using a propeller mixer to obtain a homogeneous mixture (A, B, C, D, E and F phases) as a composition according to any one of Examples 1-2 and Comparative Examples 1-4.

[0227] The amounts of the components shown in Table 1 are all based on the mass percent of the raw materials. (a) to (f) in Table 1 correspond to those within the scope of the claims.

[0228] [Table 1]

[0229] NA: Not measurable

[0230] [evaluation] (viscosity) 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.) using a Brookfield viscometer under the conditions of a rotor No. 4, a rotation speed of 6 rpm, and a measurement time of 1 minute.

[0231] The results are shown in Table 1.

[0232] (Texture conversion) Five expert panelists evaluated the "texture transformation" during application of the compositions according to Examples 1-2 and Comparative Examples 1-4. Each panelist took each composition and applied it in a circular pattern on their face. The panelists evaluated the timing of the texture transformation (from cream to liquid) and rated it from 1 (bad) to 5 (very good), then classified it into the following four categories based on the average of the ratings: Very good: 5.0-4.0 (texture transformation is clearly felt at the early stage of application) Good: 3.9-3.0 (texture transformation is felt at the early stage of application) Poor: 2.9 to 2.0 (texture transformation is difficult to feel at the initial stage of application) Very poor: 1.9 to 1.0 (no texture transformation felt at the initial stage of application)

[0233] The results are shown in Table 1.

[0234] (Non-adhesive feeling) Five expert sensory testers evaluated the "non-sticky feeling" after application of the compositions according to Examples 1-2 and Comparative Examples 1-4. Each sensory tester took each composition, applied it to their own face, evaluated the non-sticky feeling after application, and ranked it from 1 (bad) to 5 (very good), and then classified it into the following four categories based on the average of the ratings. Very good: 5.0-4.0 (no sticky feeling at all after application) Good: 3.9-3.0 (not sticky after application) Poor: 2.9 to 2.0 (stickiness felt after application) Very poor: 1.9 to 1.0 (stickiness is clearly felt after application)

[0235] The results are shown in Table 1.

[0236] (stability) Each composition according to Examples 1-2 and Comparative Examples 1-4 was filled into a glass bottle and kept for two months under temperature variations of 4° C., 25° C., 37° C., and 45° C. Each sample was then inspected for the degree of change (appearance, color, and odor) and evaluated according to the following criteria: Very good: Almost as good as when manufactured. Good: Almost no change was observed in appearance, color or odor. Poor: A clear change in appearance, color, and odor was observed. Very poor: Significant changes in appearance, color and odor were observed.

[0237] The results are shown in Table 1.

[0238] (summary) As is evident from Table 1, the compositions according to the present invention (Examples 1-2) can provide excellent cosmetic effects in terms of texture transformation during application, non-sticky feel, and stability under temperature changes for 2 months, which can be attributed to the combination of components (a)-(c). Thus, the compositions according to the present invention can provide, in particular, excellent hand feel, and long-term stability even under temperature changes.

[0239] The composition according to Example 2 is preferable to the composition according to Example 1 in terms of non-tacky feel after application due to the presence of the component (d) filler.

[0240] On the other hand, the composition according to Comparative Example 1, which does not contain component (a) (an amphiphilic polymer comprising at least one hydrophilic unit and at least one hydrophobic unit), showed poor texture transformation and instability. In addition, the viscosity of the composition according to Comparative Example 1 could not be measured due to phase separation.

[0241] The composition according to Comparative Example 2, which did not contain component (b) (a polysaccharide derived from a microorganism), showed poor texture transformation and instability.

[0242] The composition according to Comparative Example 3, which did not include component (c) (a low HLB polyglyceryl fatty acid ester having at least one hydroxyl group in the polyglyceryl moiety), showed poor texture transformation.

[0243] The composition according to Comparative Example 4, which did not contain component (c) but contained a high HLB polyglyceryl fatty acid ester having at least one hydroxyl group in the polyglyceryl moiety, showed poor texture transformation.
