Description

[Technical field]

[0001] The present invention relates to a topical composition. [Background technology]

[0002] In external use compositions such as cosmetics, depending on the combination of ingredients, the stability of physical properties may be impaired due to the influence of coexisting ingredients.

[0003] Among the required physical property stability, the durability of the composition when applied to the skin has a large impact on the feeling of use of the cosmetic. Generally, a cosmetic user takes a cosmetic in his / her hands, applies it to the skin, and spreads it, sensing stickiness, moistness, smoothness, skin compatibility, etc. as a feeling of use along with changes in the cosmetic state.

[0004] If the durability of the composition is impaired due to the influence of coexisting ingredients, the cosmetic will lose its shape retention when it is picked up or during storage, resulting in a poor usability of the cosmetic.

[0005] The feel of cosmetics when used is currently evaluated by sensory evaluation tests, but objective evaluation methods are also being developed.

[0006] For example, in Patent Document 1, a parallel plate type viscoelasticity measuring device is used to measure the storage modulus and loss modulus of an external skin preparation at each frequency, and the feel of the cosmetic is evaluated. [Prior art documents] [Patent documents]

The contents, ratios, and other conditions of each component herein are in accordance with those described in [External Composition]. EXAMPLES

[0096] Next, the present invention will be specifically described with reference to examples, but the present invention is not limited to the following examples.

[0097] [Test Example 1. Evaluation test of stability and hardness] Compositions for topical use of the examples and comparative examples were prepared. The components and contents of each composition are as shown in Table 1.

[0098] Each Example containing component (A) and component (B), and Comparative Examples 1-1 and 1-2 using a surfactant containing a polyoxyethylene structure or a hydrogenation site in its structure instead of component (B) were prepared. Each topical composition was evaluated for structural durability, high temperature durability, and hardness.

[0099] (Method of evaluating structural durability) Using a rheometer (MCR102, manufactured by Anton Paar, MESURING CONE CP35-1 D; 35 mm; ANGLE 1°), the storage modulus and loss modulus were measured by changing the shear strain (γ) of the measurement sample logarithmically from 0.01 to 100% at a measurement temperature of 25°C and a constant frequency of strain amplitude of 1 Hz.

[0100] The evaluation was performed according to the following evaluation criteria, and the results are shown in Table 1. The value of the shear strain γ at the intersection of the storage modulus and the loss modulus represents the shear required to change from solid (semi-solid) to liquid properties. On the other hand, the value of the shear strain γ 1% / 0.1% of the storage modulus represents the shear required for the structure to begin to break down in the solid (semi-solid) state. Therefore, when the above two values ​​satisfy the conditions of ○ shown in the following evaluation criteria, it is judged that the tested topical composition can stably maintain the emulsion structure. When the above evaluation criteria show △, the emulsion structure of the tested topical composition is slightly unstable. When the above evaluation criteria show ×, the emulsion structure of the tested topical composition is unstable. When the above test shows that the structure stability is high, for example, dripping and leakage when filled in a tube container or a jar container can be suppressed. In addition, when the topical composition is applied to the skin, it is judged that the adhesion to the skin is enhanced, the medicinal effect is felt to be high, and dripping is unlikely to occur during application, resulting in an excellent usability. ○: The shear strain γ at the intersection of the storage modulus and loss modulus is 1% or more, and the shear strain γ 1% / 0.1% of the storage modulus is 0.15 or more. △: The shear strain γ at the intersection of the storage modulus and loss modulus is 1% or more, and the shear strain γ 1% / 0.1% of the storage modulus is less than 0.15. ×: The shear strain γ at the intersection of the storage modulus and loss modulus is less than 1%, and the shear strain γ 1% / 0.1% of the storage modulus is less than 0.15.

[0101] (Method of evaluating high temperature durability) The composition was visually inspected. After one day of preparation and storage at room temperature, 15 g of each composition was placed in a 30 mL glass bottle, stored at 40°C for 48 hours, and visually inspected. The composition was evaluated as having shape retention as a formulation, as ○, and as being liquefied, as ×. The results are shown in Table 1.

[0102] (Hardness evaluation method) The hardness of the prepared topical composition was measured using a rheometer (product name "SUN RHEO METER CR-100", manufactured by Sun Scientific Co., Ltd.). The hardness was measured by inserting a cylindrical adapter (adapter) with a diameter of 20 mm into the center of the cylindrical container at a speed of 20 mm / min, and the maximum value (unit: g) was measured for 30 seconds from the insertion. The results are also shown in Table 1.

[0103] [Table 1]

[0104] As shown in Table 1, in Comparative Examples 1-1 and 1-2, a surfactant containing a polyoxyethylene structure or a hydrogenation site on its structure was used, and therefore, when used in combination with component (A), the structural durability and high temperature durability were reduced, and the stability and feeling of use were impaired. On the other hand, in each Example, since component (A) and component (B) coexist, structural durability and high temperature durability were maintained at a high level, and the stability during use was good. Although not limited thereto, in particular, in Examples that satisfy the evaluation criteria of a shear strain γ at the intersection of the storage modulus and the loss modulus being 1% or more, and a shear strain γ 1% / 0.1% of the storage modulus being 0.15 or more, the emulsion structure was stably maintained, and, for example, dripping and leakage were suppressed when filling a container. Furthermore, when applied to the skin, the feeling of adhesion was enhanced, and a feeling of medicinal efficacy was felt to be high.

[0105] Similarly, Table 2 shows the value of the shear strain γ at the intersection of the storage modulus and the loss modulus. [Table 2]

[0106] As shown in Table 2, the compositions of the examples maintained high structural durability and were stable during use. The emulsion structure was stably maintained, and for example, dripping and leakage were suppressed when filling a container. Furthermore, when applied to the skin, the adhesion was enhanced and a high sense of medicinal efficacy was felt.

[0107] (Evaluation of irritation and stickiness) Six subjects who are skilled in evaluating skin external preparations evaluated the irritation and stickiness. Using the compositions of Examples 15 and 16, 20 μl of each preparation was applied to the inside of one arm, and rubbed in a circular motion 10 times. After 1 minute, the subject was evaluated by questionnaire (VAS). Specifically, on a subjective symptom survey sheet with a 10 cm line drawn on it, subjects were asked to check the degree of symptoms they felt, with 0 cm being the case where no irritation or stickiness was felt, and 10 cm being the case where irritation or stickiness was felt significantly, and this length (cm) was used as the VAS evaluation value. Here, the subjects who used sunscreen or body cream started the test 10 minutes after washing it off. The results of the evaluation were judged as follows. The results are shown in the table.

[0108] feeling of irritation The number of subjects with a VAS score of less than 2.5 is 5 or more. The number of subjects with a VAS score of less than 2.5 is 3 to 4. The number of subjects with a VAS score of less than 2.5 is less than 3 × Sticky The number of subjects with a VAS score of less than 2.5 is 5 or more. The number of subjects with a VAS score of less than 2.5 is 3 to 4. The number of subjects with a VAS score of less than 2.5 is less than 3 × [Table 3]

[0109] [Prescription example] Formulation examples are shown in Table 4 below. All units are mass %. In the case of a cream formulation, it can be stored in a jar container made of polypropylene or polyethylene terephthalate, or a tube container made of polyethylene, polypropylene, polyethylene terephthalate, or aluminum laminate.

[0110] In the case of a milky lotion or emulsion form, the composition can be stored in a bottle container made of polypropylene, polyethylene, or polyethylene terephthalate, or a pump container made of polypropylene, polyethylene, or polyethylene terephthalate.
