Description

[Technical Field]

[0001] The present invention relates to a non-sticky, smooth and stable composition, preferably a cosmetic or dermatological composition. [Background technology]

[0002] Compositions containing polyglyceryl fatty acid esters are known in the fields of cosmetics and dermatology. Polyglyceryl fatty acid esters can function as surfactants and therefore can typically be used to prepare emulsions, such as oil-in-water (O / W) or water-in-oil (W / O) emulsions.

[0003] For example, JP 2015-189762, JP 2014-073991, and JP 2017-114781 disclose emulsions formed by using polyglyceryl fatty acid esters as surfactants.

[0004] However, compositions containing polyglyceryl fatty acid esters often result in a sticky or greasy feel and tend to be unstable, especially over time and / or under temperature changes.

[0005] There remains a need for new approaches to reduce the sticky feel of compositions containing polyglyceryl fatty acid esters and to stabilize the compositions. [Prior art documents] [Patent documents]

[0026] The composition according to the present invention, which contains a polyglyceryl fatty acid ester, can provide a non-greasy or smooth feel along with a non-sticky or less sticky feel.

[0027] Therefore, the composition according to the present invention can provide an excellent feel during use, in particular an excellent feel on the skin during and after application of the composition.

[0028] The term "stickiness" is used herein to mean the property of producing a sticky feeling on the skin.

[0029] The term "greasy" is used herein to mean the property of producing a slimy feeling on the skin.

[0030] The composition of the present invention is stable immediately after preparation of the composition and even after a long time after preparation of the composition, even under temperature changes from cold to hot. Therefore, the composition of the present invention is stable over time and can be stored for a long period of time, even under temperature changes from winter to summer.

[0185] The present invention will now be described in more detail by way of examples, which should not be construed as limiting the scope of the present invention.

[0186] (Examples 1 and 2 and Comparative Examples 1 to 8) The following compositions according to Examples 1 and 2 and Comparative Examples 1 to 8 shown in Table 1 were prepared by mixing the components shown in Table 1 as follows. (1) mixing the ingredients in column A of Table 1 at 70-75°C to form a homogeneous mixture of phase A; (2) adding the ingredients in column B of Table 1 to the mixture of phase A at 75-80°C, followed by homogenization to obtain a homogenous mixture (phases A and B) at 70-75°C; (3) mixing the ingredients in column C of Table 1 at 70-75°C to form a phase C mixture; (4) adding the mixture of phase C to the mixture of phases A and B at 70-75°C, followed by homogenization to obtain a homogenous mixture (phases A, B, and C) at 70-75°C, and cooling the resulting mixture to about 30°C; (5) Adding the ingredients in columns D and E of Table 1 to the mixture of phases A, B, and C at about 30°C, followed by homogenizing them to obtain a uniform mixture (phases A, B, C, D, and E) at about 30°C, and cooling the resulting mixture to room temperature.

[0187] All component amounts shown in Table 1 are based on "mass %" of the active ingredient.

[0188] [Table 1A]

[0189] [Table 1B]

[0190] [Table 1C]

[0191] [evaluation] (Non-sticky feel) Five expert panelists evaluated the "non-sticky feel" after application of the compositions according to Examples 1 and 2 and Comparative Examples 1 to 8. Each panelist took each composition in their hand, then applied it to their face, evaluated the non-sticky feel after application, and scored it from 1 (very poor) to 5 (very good), and then classified the results into the following four categories based on the average of the scores: Very good: 5.0~4.0 Good: 3.9~3.0 Bad: 2.9~2.0 Very poor: 1.9~1.0

[0192] The results are shown in Table 1.

[0193] (Smooth feel) Five expert panelists evaluated the "smooth feel (non-greasy feel)" during application of the compositions according to Examples 1 and 2 and Comparative Examples 1 to 8. Each panelist took each composition in their hand, then applied it to their face, evaluated the smooth feel (non-greasy feel), and scored it from 1 (very poor) to 5 (very good), and then classified it into the following four categories based on the average score: Very good: 5.0~4.0 Good: 3.9~3.0 Bad: 2.9~2.0 Very poor: 1.9~1.0

[0194] The results are shown in Table 1.

[0195] (temperature stability) Each of the compositions according to Examples 1 and 2 and Comparative Examples 1 to 8 was filled into a glass bottle and stored for two months under varying temperature conditions of 4°C, 25°C, 40°C, and 45°C. Each sample was then inspected for the degree of change (color, odor, and pH) and evaluated according to the following criteria: Very Good: Almost as good as when manufactured. Good: Some changes in color, odor, and pH were observed, but no separation or creaming or crystallization was observed. Poor: Changes in color, odor, and pH were clearly observed. Separation or creaming or crystallization was clearly observed. Very poor: noticeable changes in color, odor, and pH. Signs of separation or creaming or crystallization were noticeable.

[0196] The results are shown in Table 1.

[0197] As is clear from Table 1, the compositions in the form of O / W emulsions according to the present invention (Examples 1 and 2) can provide excellent cosmetic effects in terms of non-sticky feel, smooth feel, and stability under temperature changes for two months, which can be attributed to the combination of components (b) and (c) under certain conditions. Therefore, the compositions according to the present invention can provide, in particular, excellent feel and long-term stability under temperature changes.

[0198] On the other hand, Comparative Example 1 did not satisfy the condition that the mass ratio of the amount of component (b) / the amount of component (c) was more than 15 and less than 35, and showed poor temperature stability.

[0199] Comparative Example 2 did not satisfy the conditions (i) that the weighted average of the HLB values ​​of components (b) and (c) is between 8 and 11, and (ii) that the mass ratio of the amount of component (b) to the amount of component (c) is greater than 15 and less than 35, and exhibited poor temperature stability. In particular, crystallization was observed in Comparative Example 2 during stability evaluation.

[0200] Comparative Examples 3 and 4 did not satisfy the condition that the weighted average of the HLB values ​​of components (b) and (c) be between 8 and 11, and showed poor temperature stability.

[0201] Comparative Example 5, which did not use component (c), showed a poorer non-sticky feel or a poorer smooth feel.

[0202] Comparative Example 6, which did not use component (a), showed very poor cosmetic effects in terms of any one of non-sticky feel, smooth feel, and temperature stability.

[0203] Comparative Example 7, which did not use component (d), showed a poorer non-sticky feel or a poorer smooth feel.

[0204] Comparative Example 8, which did not use component (e), showed poor non-sticky feel and poor temperature stability.
