Description

[Technical Field]

[0001] The present invention relates to a hair styling composition, a hair styling aerosol spray, and a hair styling method. [Background technology]

[0002] Hair styling compositions used for styling hair usually contain hair styling ingredients such as solid oils, hair styling polymers, etc. In addition to the above-mentioned hair styling ingredients, various other ingredients are used to impart various functions to the hair styling composition.

[0003] For example, Patent Document 1 listed below proposes a technology in which a hair styling agent in a non-aerosol foamer container containing polyoxypropylene alkyl glucoside, a film-forming polymer, and a surfactant is used, which not only has excellent compatibility with dry hair and foam quality, but also restores the curls and uniformity of disordered waves to their pre-disarray state. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-253046 Summary of the Invention [Problem to be solved by the invention]

[0005] Some hair styling compositions have a hair styling function when first used, as well as a hair restyling function, such as restoring a hairstyle that has become messy after styling, as shown in Patent Document 1, or changing hair that has already been styled into a different hairstyle according to preference.

[0006]

[0003] Hair styling compositions with hair restyling functions that contain a hair styling polymer as a hair styling ingredient adhere the hair styling polymer to the hair, thereby exerting their hair styling function. However, hair styling compositions containing a hair styling polymer can have problems in that after the hair styling polymer adheres to the hair during the initial styling, a film of the hair styling polymer hardens on the hair, making it difficult to restyling the hair and further resulting in poor hair restyling power (setting power when restyling the hair). The same problems can also occur with hair styling aerosol sprays containing hair styling compositions containing a hair styling polymer as a hair styling ingredient.

[0007] Therefore, there is a demand for hair styling compositions and hair styling aerosol sprays that have excellent restyling properties even when they contain hair styling polymers.

[0008] In view of the above circumstances, an object of the present invention is to provide a hair styling composition or a hair styling aerosol spray that has excellent restyling properties. Another object of the present invention is to provide a hair styling method using a hair styling composition or a hair styling aerosol spray that has excellent restyling properties. [Means for solving the problem]

[0009] As a result of extensive research, the present inventors have discovered that a hair styling composition with excellent restyling properties can be provided by blending an acrylic resin alkanolamine, a polyoxyethylene-methylpolysiloxane copolymer, and a lower alcohol and spraying the composition onto hair, and that a hair styling method using this hair styling composition also provides excellent hair restyling properties, which has led to the completion of the present invention.

[0010] That is, the hair styling composition according to the present invention comprises: (A), (B), and (C) below: (A) acrylic resin alkanolamine, (B) polyoxyethylene-methylpolysiloxane copolymer, (C) lower alcohols, is blended, It is sprayed onto hair.

[0011] The hair styling composition according to the present invention preferably contains, as the (B) polyoxyethylene-methylpolysiloxane copolymer, a polyoxyethylene-methylpolysiloxane copolymer having an average number of moles of ethylene oxide added of 2 or more, because this allows for the realization of a hair styling composition with superior hair restyling ability.

[0012] The hair styling composition according to the present invention is characterized in that the (B) polyoxyethylene-methylpolysiloxane copolymer has a kinematic viscosity of 3000 mm at 25°C. 2 It is preferable that the composition contains a polyoxyethylene-methylpolysiloxane copolymer having a viscosity of not more than 1 / s, since this allows for a hair styling composition with superior restyling power to be achieved.

[0013] The hair styling composition according to the present invention contains, as the (A) acrylic resin alkanolamine, one or more selected from the group consisting of alkanolamine salts of (acrylates / alkyl(C1-18) acrylate / alkyl(C1-8) acrylamide) copolymers, alkanolamine salts of (acrylates / diacetoneacrylamide) copolymers, and alkanolamine salts of (acrylates / alkyl(C1-18) acrylate / alkyl(C1-8) acrylamide / hydroxyethyl acrylate) copolymers.

[0014] In the hair styling composition according to the present invention, it is preferable that the mass ratio of the amount of the (B) polyoxyethylene-methylpolysiloxane copolymer to the amount of the (A) acrylic resin alkanolamine is 0.4 or more, since this allows for a hair styling composition with superior hair restyling ability to be achieved.

[0015] The hair styling aerosol spray according to the present invention is an aerosol container filled with any one of the above-described hair styling compositions according to the present invention and a propellant.

[0016] The hair styling method according to the present invention uses any of the above-described hair styling compositions according to the present invention or the above-described hair styling aerosol spray. [Effects of the Invention]

[Example]

[0072] The present invention will be described in detail below based on examples, but the present invention should not be construed as being limited by the descriptions in these examples.

[0073] (Examples 1 to 13, Comparative Examples 1 to 8) Aerosol hair sprays of Examples 1 to 13 and Comparative Examples 1 to 8 were prepared as follows and evaluated.

[0074] (Preparation of Examples 1 to 13 and Comparative Examples 1 to 8) Hair styling compositions according to Examples 1 to 13 and Comparative Examples 1 to 8 were prepared by mixing the ingredients according to a known method for producing hair styling compositions to obtain the compositions shown in Tables 1, 3, and 4 below. Then, 55 parts by weight of each hair styling composition according to Examples 1 to 13 and Comparative Examples 1 to 8 were filled into pressure-resistant aerosol containers with 45 parts by weight of propellant, to obtain the aerosol hair sprays of Examples 1 to 13 and Comparative Examples 1 to 8. LPG and DME were used in combination as the propellant (the mixing ratios of LPG and DME are shown in Tables 1 to 5). The LPG used had a pressure of 0.20 MPa at 25°C.

[0075] The valve used in the pressure-resistant aerosol container was an S13 series valve (stem hole diameter 0.4 mm, housing side hole diameter 0.4 mm, housing pilot hole diameter 0.6 mm) manufactured by Mitani Valve Co., Ltd. The button used in the pressure-resistant aerosol container was a mechanical break-up type valve (nozzle hole diameter 0.5 mm) manufactured by Mitani Valve Co., Ltd.

Table 6 also shows the raw materials (*1) to (*6) used in (A) blended into the aerosol hair sprays of Examples 1 to 13 and Comparative Examples 1 to 8 in Tables 1 to 5.

[0077] (evaluation) Using the aerosol hair sprays of Examples 1 to 13 and Comparative Examples 1 to 8 prepared above, the "hair restyling ability" and "durability of hair restyling ability" were evaluated by the following evaluation methods.

[0078] (Evaluation method) An evaluation wig (manufactured by Regina) with a hair length of approximately 35 cm was prepared. The hair of the evaluation wig was divided into six evaluation areas so that the hair strands were the same amount. The hair in one evaluation area was lifted by hand and sprayed with the standard aerosol hairspray over the entire hair in that evaluation area for two seconds to style it. The hair in the remaining five evaluation areas was similarly styled by lifting the hair in each evaluation area by hand and spraying a different aerosol hairspray from the standard over the entire hair in each evaluation area for two seconds. Next, after leaving the spraying for five minutes, the dried hair in each evaluation area was pinched with fingers to curl it, and the "restyleability" (setting ability when restyled) was evaluated. Furthermore, the hair in each evaluation area was combed three times with a comb to break up the shape of the curled hair, and then the hair in each evaluation area was pinched with fingers to curl it again, and the "durability of restyleability" (setting ability when restyled) was evaluated. Each evaluation was carried out by five evaluators who regularly evaluate hair styling compositions, and the evaluation results were judged by consensus of the five evaluators according to the following evaluation criteria.

[0079] (Evaluation criteria for hair restyling ability) ○: Superior restyling power compared to the standard aerosol hair spray (has stronger setting power when restyling hair and is easier to style into curls compared to the standard aerosol hair spray). Equivalent: Equivalent restyling power to the standard aerosol hairspray (same level of setting power when restyling and same level of ease in styling into curls compared to the standard aerosol hairspray). ×: Poorer restyling power compared to the standard aerosol hair spray (weak setting power when restyling compared to the standard aerosol hair spray, making it difficult to style hair into curls).

[0080] (Evaluation criteria for durability of restyling ability) ○: Compared to the standard aerosol hair spray, it has excellent durability in restyling power (it has stronger setting power when re-styling and is easier to style into curls compared to the standard aerosol hair spray). Equivalent: Equivalent retention of restyling power compared to the standard aerosol hairspray (same level of hold when restyling hair again and same level of ease in styling into curls compared to the standard aerosol hairspray). ×: Compared to the standard aerosol hair spray, the re-styling power is less durable (compared to the standard aerosol hair spray, the setting power is weaker when re-styling, and it is difficult to style the hair into curls).

[0081] (Evaluation results) The evaluation results of the aerosol hair sprays of Examples 1 to 13 and Comparative Examples 1 to 8 are shown in Tables 1 to 5 below.

[0082] (Evaluation Results of Examples 1 to 5 and Comparative Examples 1 to 6) Table 1 below shows the composition of each blended component, as well as the evaluation results of the aerosol hair sprays of Examples 1 to 5 and Comparative Examples 1 to 6. The aerosol hair spray of Comparative Example 2 was used as the evaluation standard.

[0083] [Table 1]

[0084] The results shown in Table 1 show that the aerosol hair sprays of Examples 1 to 4, which contained (A) to (C), were superior in both the evaluation of hair restyling ability and the durability of hair restyling ability compared to the aerosol hair sprays of Comparative Examples 1 to 5, which lacked (B). Therefore, it can be understood that the incorporation of (A) to (C) into the hair styling composition results in excellent hair restyling ability and durability of hair restyling ability.

[0085] (Evaluation Results of Examples 1 to 5) Table 2 below shows the evaluation results of the aerosol hair sprays of Examples 1 to 5 (see Table 1 above for the compositions of the ingredients in Examples 1 to 5). The aerosol hair sprays of Examples 2, 4, and 5 were used as the standard for evaluating the restyling ability, and the aerosol hair sprays of Examples 4 and 5 were used as the standard for evaluating the durability of the restyling ability. Note that the shaded areas in the evaluation columns of Table 2 indicate areas that were not evaluated.

[0086] [Table 2]

[0087] The results shown in Table 2 indicate that the aerosol hairsprays of Examples 1 to 4, which use (B) with an average number of moles of ethylene oxide added of 10 or more, have superior restyling power compared to the aerosol hairspray of Example 5, which uses (B) with an average number of moles of ethylene oxide added of 3. In addition, the kinematic viscosity at 25°C of 1700 mm 2 The kinematic viscosity at 25°C was 400 mm / s compared to the aerosol hair spray of Example 2 using (B). 2 It can be seen that the aerosol hair sprays of Examples 1, 3, and 4, which used (B) at an average addition mole number of ethylene oxide of 10 and a kinematic viscosity of 400 mm at 25°C, have better hair restyling power. 2 Compared with the aerosol hair spray of Example 4 using (B) at 25°C, the average number of moles of ethylene oxide added was 12 and the kinematic viscosity at 25°C was 400 mm 2 It can be seen that the aerosol hair spray of Example 1 using (B) of 1 / s has superior restyling power.

[0088] From the results shown in Table 2, the average number of moles of ethylene oxide added is 3, and the kinematic viscosity is 150 mm 2 Compared with the aerosol hair spray of Example 5 using (B) at 25°C, the average number of moles of ethylene oxide added is 10 or more and the kinematic viscosity at 25°C is 400 mm 2 The aerosol hair sprays of Examples 1 and 4, which used (B) at an average addition mole number of ethylene oxide of 10 and a kinematic viscosity of 400 mm at 25°C, were found to be superior in durability of restyling power. 2 Compared with the aerosol hair spray of Example 4 using (B) at 25°C, the average number of moles of ethylene oxide added was 12 and the kinematic viscosity at 25°C was 400 mm 2 It can be seen that the aerosol hair spray of Example 1 using (B) of 1 / s has superior durability of restyling power.

[0089] (Evaluation results of Examples 1, 6 to 10, and Comparative Examples 7 and 8) Table 2 below shows the composition of each blended component, as well as the evaluation results of the aerosol hair sprays of Examples 1, 6 to 10, and Comparative Examples 7 and 8. The aerosol hair spray of Comparative Example 7 was used as the evaluation standard.

[0090] [Table 3]

[0091] The results shown in Table 3 show that the aerosol hair sprays of Examples 1 and 6 to 10, which contained (A) to (C), were superior in both the ability to restyle hair and the durability of the ability to restyle hair, compared to the aerosol hair sprays of Comparative Examples 7 and 8, which lacked (A).

[0092] (Evaluation results of Examples 1, 11 to 13, and Comparative Example 1) Table 4 below shows the composition of each blended component, as well as the evaluation results of the aerosol hair sprays of Examples 1, 11 to 13, and Comparative Example 1. The aerosol hair spray of Comparative Example 1 was used as the evaluation standard.

[0093] [Table 4]

[0094] The results shown in Table 4 indicate that the aerosol hair sprays of Examples 1 and 11 to 13, which contain (A) to (C), are superior in both the ability to restyle hair and the durability of the ability to restyle hair, compared to the aerosol hair spray of Comparative Example 1, which lacks (B).

[0095] (Evaluation results of Examples 1, 11 to 13) Table 5 below shows the evaluation results of the aerosol hair sprays of Examples 1, and 11 to 13 (see Table 4 above for the composition of each compounded ingredient in Examples 1, 11 to 13). The aerosol hair spray of Example 11 or 12 was used as the evaluation standard. Note that the shaded areas in the evaluation column of Table 5 indicate that no evaluation has been performed.

[0096] [Table 5]

[0097] The results shown in Table 5 indicate that the aerosol hair sprays of Examples 1 and 13, which had a mass ratio [(B) / (A)] of 0.8 or more, were superior in the evaluation of hair restyling ability compared to the aerosol hair sprays of Examples 11 and 12, which had a mass ratio [(B) / (A)] of 0.6 or less. It can be seen that the aerosol hairsprays of Examples 1, 12, and 13, which have a mass ratio [(B) / (A)] of 0.6 or more, are superior in the evaluation of durability of hair restyling power compared to the aerosol hairspray of Example 11, which has a mass ratio [(B) / (A)] of 0.4. It can also be seen that the aerosol hairsprays of Examples 1 and 13, which have a mass ratio [(B) / (A)] of 0.8 or more, are superior in the evaluation of durability of hair restyling power compared to the aerosol hairspray of Example 12, which has a mass ratio [(B) / (A)] of 0.6. Therefore, it can be understood that an aerosol hair spray containing (A) to (C) has excellent restyling power and durability if the mass ratio [(B) / (A)] is 0.6 or more, and is excellent in both restyling power and durability if the mass ratio [(B) / (A)] is 0.8 or more.
