Description

[Technical Field]

[0001] This invention relates to a composition, a cosmetic method using the composition, and a method for reducing primary skin irritation from the composition. [Background technology]

[0002] Cosmetic and other compositions are available in various forms, each containing different ingredients depending on its intended purpose.

[0003] As an example of a composition, Patent Document 1 discloses a hair cosmetic characterized by containing a predetermined amount of ethylhexyl methoxycinnamate, diethylamino hydroxybenzoyl hexyl benzoate, and a cationic surfactant. [Prior art documents] [Patent Documents]

[0004] [Patent Document 1] Japanese Patent Publication No. 2016-166165 [Overview of the Initiative] [Problems that the invention aims to solve]

[0005] Cationic surfactants may be included as ingredients in the composition, as shown in Patent Document 1. Cationic surfactants may be used to enhance the preservative power of the formulation or to improve the feel of the hair when the composition is used on the hair.

[0006] However, in the case of a composition containing a cationic surfactant, skin primary irritation may easily occur depending on the composition content (combination with other compounding ingredients and compounding amount), method of use, etc. In particular, in a composition containing a cationic surfactant, when the amount of water added is relatively small, the concentration of the cationic surfactant dispersed or dissolved in water becomes relatively high, and skin primary irritation may more easily occur. Also, in this case, when the above composition is adhered to the skin (including the scalp) and not rinsed off with water, skin primary irritation may more easily occur.

[0007] Therefore, in a composition containing a cationic surfactant, it is desired to reduce the possibility of skin primary irritation.

[0008] In view of the above circumstances, an object of the present invention is to provide a composition with reduced skin primary irritation in a composition containing a cationic surfactant. Another object of the present invention is to reduce skin primary irritation in a beauty method using a composition containing a cationic surfactant.

In a composition containing a cationic surfactant, water, and a specific oil, increasing the amount of specific oil reduces the amount of water, resulting in a relatively high concentration of the cationic surfactant dispersed or dissolved in water, which tends to cause primary skin irritation. However, in the composition of the second embodiment, even when the amount of water is relatively low due to a high amount of specific oil, the inclusion of one or more selected from (A), etc., reduces primary skin irritation caused by the cationic surfactant.

[0212] <Cationic surfactants> The composition of the second embodiment contains one or more cationic surfactants. The types and amounts of cationic surfactants included in the composition of the second embodiment are the same as those in the composition of the first embodiment, and the description of "<cationic surfactant>" in the composition of the first embodiment shall be read as "composition of the second embodiment" and applied mutatis mutandis.

[0222] The composition of the second embodiment contains water and a cationic surfactant, and the amount of specific oil is 50% by mass or more. Therefore, the concentration of the cationic surfactant dispersed or dissolved in water tends to be relatively high. However, by incorporating one or more of the above-mentioned (A) to (K), primary skin irritation caused by the cationic surfactant can be reduced. Furthermore, by setting the amount of specific oil in the composition of the second embodiment to 50% by mass or more, a large amount of oil can be applied to the object on which the composition is used (e.g., hair or skin). For example, when the composition of the second embodiment is used on hair or skin, it can impart a more oily feel to the hair or skin.

[0223] The amount of specific oil in the composition of the second embodiment is 50% by mass or more, but may be, for example, 55% by mass or more. From the viewpoint of imparting a more oily feel to the hair or skin when the composition is used on the hair or skin, 55% by mass or more is preferred, 60% by mass or more is more preferred, 65% by mass or more is even more preferred, and 70% by mass or more is even more preferred.

[0225] The range of the amount of specific oil blended in the composition of the second embodiment may be, for example, 50% by mass or more and 95% by mass or less, or 55% by mass or more and 95% by mass or less. From the above viewpoint, 55% by mass or more and 90% by mass or less is preferred, 60% by mass or more and 87% by mass or less is more preferred, 65% by mass or more and 85% by mass or less is even more preferred, and 70% by mass or more and 85% by mass or less is even more preferred.

[0226] (Ratio of [cationic surfactant / oil other than higher alcohol]) In the composition of the second embodiment, the mass ratio of the blending amount of the cationic surfactant to the blending amount of the oil other than the higher alcohol ([cationic surfactant / oil other than higher alcohol] ratio) may be set as appropriate.

[0227] The composition of the second embodiment may have, for example, a [cationic surfactant / oil other than higher alcohol] ratio of 0.002 or more. From the viewpoint of being able to make hair softer, a ratio of 0.003 or more is preferable, a ratio of 0.005 or more is more preferable, and a ratio of 0.01 or more is even more preferable.

[Examples]

[0239] The present invention will be described in detail below based on examples, but the present invention should not be interpreted as being limited based on the description of these examples.

[0240] (Preparation of compositions for Examples 1-24 and Comparative Examples 1-3) The compositions of Examples 1-24 and Comparative Examples 1-3 were prepared by mixing components selected from the following list of components using conventional methods to achieve the compositions shown in Tables 2-8. The prepared compositions of Examples 1-24 and Comparative Examples 1-3 all had a dosage form of slightly cloudy gel (viscosity within the range of 3000 mPa·s to 30000 mPa·s (25°C, B-type viscometer)). In Tables 2-8, the units of the numerical values ​​in the component column are mass%, and the notation "-" indicates that the component was not included.

[0241] (Ingredients used) • Cationic surfactants Stearyltrimethylammonium chloride ·water purified water ·(A) etc. PEG-12 Dimethicone (Kinematic viscosity 1600 mm) 2 / s), cetanol, PEG-12 dimethicone (kinematic viscosity 400 mm) 2 / s), PEG-3 Dimethicone, PEG-11 Methyl Ether Dimethicone, PEG / PPG-20 / 22 Butyl Ether Dimethicone, Lauramidopropyl Betaine, Sodium Laureth-6 Acetate, (C12-14) Pareth-7, (C12-14) Pareth-12, Cocamide Methyl MEA, Sorbet-30 Tetraoleate, PPG-4 Ceteth-20, PEG-10 Hydrogenated Castor Oil, PEG-60 Hydrogenated Castor Oil, Oleth-2, Glyceryl Caprate (A) and other comparative components Polyglyceryl-3 polydimethylsiloxyethyl dimethicone, laureth-2 ·Specified oil Dimethicone, Dimethiconol Other ingredients Glycerin, Isopropanol

[0242] Here, the above PEG-12 dimethicone (kinematic viscosity 1600 mm) 2 / s), PEG-12 dimethicone (kinematic viscosity 400 mm) 2 / s) "mm 2The value of " / s" refers to the kinematic viscosity at 25°C measured in accordance with the First Method of Viscosity Measurement in the General Test Methods of Pharmaceutical Excipient Raw Material Standards 2021. Among the above-mentioned ingredients used, the kinematic viscosities at 25°C of PEG-3 dimethicone, PEG-11 methyl ether dimethicone, PEG / PPG-20 / 22 butyl ether dimethicone, and polyglyceryl-3 polydimethylsiloxyethyl dimethicone are 150 mm 2 / s, 130 mm 2 / s, 1600 mm 2 / s, 4000 mm 2 / s, respectively.

[0243] (Evaluation) Using the compositions in Examples 1 to 24 and Comparative Examples 1 to 3 prepared above, the following human patch test was used for evaluation.

[0244] (Human Patch Test) In the human patch test, the compositions in Examples 1 to 24 and Comparative Examples 1 to 3 were used as test products, and physiological saline was used as a reference product. The test was conducted according to the method of the human patch test described in Reference 1 shown below (a certain amount of the test product and reference product were applied to the upper arm, the application time was 24 hours, occlusion was applied, and the number of subjects was 10). Then, 1 to 2 hours after patch removal and 24 hours after patch removal, the skin reactions of each subject were scored according to the indicators shown in Table 1. Among the scores obtained 1 to 2 hours after patch removal and 24 hours after patch removal, for each subject, the larger of any of the numerical values was adopted as the "subject's score", and the skin irritation index was calculated by the formula shown below. For convenience, the evaluation of the compositions in Examples 1 to 12 and Comparative Examples 1 to 2 and the evaluation of the compositions in Examples 13 to 24 and Comparative Examples 1 and 3 were conducted in separate groups of subjects (10 each).

[0246]

Table 1

[0247] Skin irritation index = (Sum of each subject's score (excluding the scores of false positive subjects) / Number of subjects excluding the number of false positive subjects) × 100 A false positive subject is defined as a subject who showed a reaction score of 0.5 or higher with the reference sample (physiological saline) 1-2 hours or 24 hours after patch removal.

[0248] Here, a lower skin irritation index value indicates lower primary skin irritation.

[0249] (Evaluation results for Examples 1-12 and Comparative Examples 1-2) Tables 2 to 4 below show the evaluation results for the compositions of Examples 1 to 12 and Comparative Examples 1 to 2. The skin irritation index for the compositions of Examples 1 to 12 and Comparative Examples 1 to 2 was obtained from the results of 9 subjects out of a group of 10 subjects, excluding one subject who showed a false positive reaction with physiological saline.

[0250] [Table 2]

[0251] From the results shown in Table 2, (A) etc. is PEG-12 dimethicone (kinematic viscosity 1600 mm) 2 The compositions of Examples 1-3, which contained (A), had lower skin irritation index values ​​compared to the compositions of Comparative Examples 1-2, which did not contain (A), etc., indicating that primary skin irritation was reduced. Furthermore, from the skin irritation index results for the compositions of Examples 1-3, it was found that PEG-12 dimethicone (kinematic viscosity 1600 mm) 2 When the amount of / s) included was 0.50% by mass or more, the skin irritation index value was lower (comparison between Examples 2 and 3 and Example 1).

[0252] [Table 3]

[0253] As shown in Table 3, the compositions of Examples 4-6, which contained cetanol ((C)) as (A), etc., had lower skin irritation index values ​​compared to the compositions of Comparative Examples 1-2, which did not contain (A), etc., indicating a reduction in primary skin irritation. Furthermore, the skin irritation index results for the compositions of Examples 4-6 showed that when the amount of cetanol was 1.50% by mass or more, the skin irritation index value was even lower (comparison of Example 6 with Examples 4 and 5).

[0254] [Table 4]

[0255] [Table 5]

[0256] As shown in Tables 4 and 5, the compositions of Examples 3-4 and 7-12, which contained (A), (C), (E), and (F) as (A), etc., had lower skin irritation index values ​​compared to the compositions of Comparative Examples 1-2, which did not contain (A), etc., indicating that primary skin irritation was reduced. Furthermore, from the skin irritation index results for the compositions of Examples 4-12, as (A), etc., PEG-12 dimethicone (kinematic viscosity 400 mm) 2 (A) and PEG / PPG-20 / 22 butyl ether dimethicone (both (A)) had the lowest skin irritation index values ​​(compositions of Examples 7 and 9), followed by PEG-12 dimethicone (kinematic viscosity 1600 mm) 2 (A), PEG-11 methyl ether dimethicone (A), lauramidopropyl betaine (E), and cetanol (C) had low skin irritation index values ​​(compositions of Examples 3, 8, 9, 11, and 4), followed by sodium laureth-6 acetate (F) (composition of Example 12). The composition of Comparative Example 2, which contained polyglyceryl-3 polydimethylsiloxyethyl dimethicone (comparative ingredient such as A), had a slightly higher skin irritation index value compared to the composition of Comparative Example 1, indicating that it was not able to reduce primary skin irritation.

[0257] Therefore, the results shown in Tables 2 to 5 indicate that when (A), (C), (E), and (F) are added as (A), etc., in a composition containing a cationic surfactant and water, primary skin irritation can be reduced.

[0258] (Evaluation results for Examples 13-24 and Comparative Examples 1 and 3) Tables 6 to 8 below show the evaluation results for the compositions of Examples 13 to 24 and Comparative Examples 1 and 3. Note that the results for Examples 13 to 24 and Comparative Examples 1 and 3 were obtained from a group of 10 subjects (no false positives). Furthermore, while Comparative Example 1 is common to both the "Evaluation Results for Examples 1 to 12 and Comparative Examples 1 to 2" and the "Evaluation Results for Examples 13 to 24 and Comparative Examples 1 and 3" shown below, the skin irritation index values ​​differ because the subject groups in the two evaluations are different.

[0259] [Table 6]

[0260] From the results shown in Table 6, the compositions of Examples 13 to 15, in which (C12-14) Pareth-7 ((B)) was incorporated as (A), etc., and PEG-12 dimethicone (kinematic viscosity 1600 mm) 2 The composition of Example 16, which contained (A) and (C12-14) Pareth-7 (B), had a lower skin irritation index value compared to the compositions of Comparative Examples 1 and 3, which did not contain (A), etc., indicating a reduction in primary skin irritation. Furthermore, from the skin irritation index results for the compositions of Examples 13 to 15, the skin irritation index value was even lower when the amount of (C12-14) Pareth-7 was 0.50% by mass or more (comparison of Examples 14 and 15 with Example 13). In addition, from the skin irritation index results for the compositions of Examples 14 to 16, it was found that as (A), etc., PEG-12 dimethicone (kinematic viscosity 1600 mm) 2When (A) and (B) were combined in a formulation (combination of (A) and (B)), the skin irritation index was even lower compared to when (C12-14) Pareth-7 was included alone ((A) only), due to the synergistic effect of combining (A) and (B) (comparison between Example 16 and Examples 14 and 15).

[0261] [Table 7]

[0262] [Table 8]

[0263] As shown in Tables 7 and 8, the compositions of Examples 15, 17-24, which contained (B), (D), (G), (H), (I), (J), and (K) as (A), etc., had lower skin irritation index values ​​compared to the compositions of Comparative Examples 1 and 3, which did not contain (A), etc., indicating a reduction in primary skin irritation. Furthermore, from the skin irritation index results for the compositions of Examples 15, 17-24, (C12-14) Pareth-12 ((B)) and Cocamide Methyl MEA ((D)) had the lowest skin irritation index values ​​(compositions of Examples 17-18), followed by (C12-14) Pareth-7 ((B)) and Sorbeth-30 Tetraoleate ((G)) (compositions of Examples 15 and 19), and then PPG-4 Ceteth-20((H)) and PEG-10 hydrogenated castor oil((I)) showed low skin irritation index values ​​(compositions of Examples 20-21), followed by PEG-60 hydrogenated castor oil((I)) (composition of Example 22), then Oleth-2((J)) (composition of Example 23), and finally, glyceryl caprate((K)) showed a low skin irritation index value (composition of Example 24). Note that the composition of Comparative Example 3, which contained laureth-2((A), etc., a comparative component), showed a slightly higher skin irritation index value compared to the composition of Comparative Example 1, indicating that it failed to reduce primary skin irritation.

[0264] Therefore, the results shown in Tables 6 to 8 indicate that when (B), (D), (G), (H), (I), (J), and (K) are added to a composition containing a cationic surfactant and water, primary skin irritation can be reduced.

[0265] Therefore, taking into account the results shown in Tables 2 to 8, it can be seen that primary skin irritation can be reduced when one or more of the following are added to a composition containing a cationic surfactant and water: (A), etc.
