Description

[Technical Field]

[0001] The present invention relates to a mist-type hair cosmetic composition, and in particular to a mist-type hair cosmetic composition to be applied before using a hair iron, which can be sprayed in mist form, allows fingers to run smoothly through the hair when applied, and has good hold and gives manageability and shine to hair despite not leaving a sticky or filmy finish. [Background technology]

[0002] Nowadays, with the spread of social media, anyone can easily watch videos on easy hair styles and how to curl their hair, making it easy to enjoy doing your own hair.

[0003] Hair irons are one of the tools used for styling hair. In recent years, the types of hair irons that have become popular include straightening irons that straighten hair and curling irons that curl hair.

[0004] However, using a hair iron can denature the proteins in the hair, leading to damage, so there is a growing demand for styling products that protect hair from heat and are applied before using a hair iron.

[0005] In recent years, a finish that emphasizes manageability and shine has become popular, but there is a concern that if an oily hair cosmetic such as hair oil or balm is applied before using a hair iron, the hair cosmetic will not volatilize and the hair iron will become dirty. Therefore, water-based hair cosmetics are preferred as hair cosmetics to be applied before using a hair iron, and mist-type hair cosmetics that can be applied widely and evenly with one hand are particularly preferred.

[0006] Various formulations of mist-type hair cosmetic compositions that are applied before using a hair iron have been developed with the aim of protecting the hair from heat (Patent Document 1), preventing the sound of evaporation when the iron is applied and providing smoothness to the hair (Patent Document 2), and making it easier to style the hair by providing softness to the hair (Patent Document 3). [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Japanese Patent Application Laid-Open No. 2010-189306 [Patent Document 2] Japanese Patent Application Publication No. 2019-43852 [Patent Document 3] Japanese Patent Application Laid-Open No. 2011-98932 Summary of the Invention [Problem to be solved by the invention]

[0008] However, the composition of Patent Document 1 sometimes leaves a crisp, filmy feeling due to the resin after using a hair iron. The compositions of Patent Documents 2 and 3 leave a light finish, impairing manageability and shine. Furthermore, with aqueous hair cosmetics applied before using a hair iron, moisture evaporates when the hair iron is used, and the resin must provide hold, making it difficult to achieve manageability and shine without the filmy feeling due to the resin.

[0009] Therefore, the present invention relates to a mist-type hair cosmetic composition, and in particular, an object of the present invention is to provide a mist-type hair cosmetic composition that is to be applied before using a hair iron, that can be sprayed in mist form, that allows fingers to run smoothly through the hair when applied, and that has good hold and gives manageability and shine to hair despite not leaving a sticky or filmy finish. [Means for solving the problem]

[0010] In view of these circumstances, the present inventors have conducted extensive research and have discovered that by incorporating (A) an amphoteric film-forming resin, (B) a nonionic surfactant with an HLB of 6.5 or more, and (C) a modified silicone into a mist-type hair cosmetic composition to be applied before using a hair iron, the composition can be sprayed in mist form, the hair feels smooth to the touch when applied, and the finished product has good hold, manageability, and shine despite not being sticky or having a filmy feel. This discovery led to the completion of the present invention. [Effects of the Invention]

[0011] To provide a mist-type hair cosmetic composition to be applied before using a hair iron, which can be sprayed in the form of a mist, allows smooth finger-combing when applied, and has good hold and gives manageability and shine to hair despite not leaving a sticky or filmy finish.

[0065] "Mist-like" A mist-type hair cosmetic composition colored with Red No. 106 was sprayed parallel to the ground from a distance of 15 cm from the paper, and the state of the mist was observed. The experiment was conducted in a location that was not affected by wind from air conditioning equipment. The state of the mist was evaluated on a four-point scale: ◎ (good), ○ (fairly good), △ (fairly poor), and × (poor) by drawing the largest circle that could be drawn within the sprayed and colored area. (Judgment criteria) Diameter 15cm or more: ◎ Diameter 10cm or more but less than 15cm: Yes Diameter 5cm or more but less than 10cm: △ Diameter less than 5cm: ×

[0066] "Smoothness of the fingers" Five panelists applied 1.8 g of the mist-type hair cosmetic compositions obtained in the Examples and Comparative Examples to half of a hair test doll (100% human black hair, model number: Queen Cut No. 775N, manufactured by Beaulux Co., Ltd.), and evaluated the ease of running their fingers through the hair when blending it with their hands using a sensory test on a 5-point scale of 5 points (very good), 4 points (good), 3 points (slightly good), 2 points (slightly poor), and 1 point (poor). An average score was calculated for all panelists, and the results were judged according to the following average score judging criteria. (Average score criteria) 4.0 points or above: 5 3.5 or above but below 4.0: 4 3.0 or above but below 3.5: 3 2.0 or more and less than 3.0: 2 Below 2.0 points: 1

[0067] "Non-sticky" Five panelists applied 1.8 g of the mist-type hair cosmetic compositions obtained in the Examples and Comparative Examples to half of a hair test doll (100% human black hair, model number: Queen Cut No. 775N, manufactured by Beaulux Co., Ltd.) and massaged it in with their hands. After dividing the hair of half of the hair test doll into 10 equal sections, they curled one section, 30 cm from the ends, using a Babyliss Pro MiraCurl (model number: BAB-2665-KJ, manufactured by Conair Japan, LLC) at 190°C for 8 seconds in a clockwise direction. This procedure was repeated for five sections. The Babyliss Pro MiraCurl is an automatic curling iron that automatically curls and curls hair when the hair section is clamped in the Babyliss Pro MiraCurl. After loosening the five bundles by hand, the lack of stickiness was evaluated sensorily on a five-point scale of 5 points (very good), 4 points (good), 3 points (fairly good), 2 points (fairly poor), and 1 point (poor). The average score was calculated and then judged according to the following average score judging criteria. (Average score criteria) 4.0 points or above: 5 3.5 or above but below 4.0: 4 3.0 or above but below 3.5: 3 2.0 or more and less than 3.0: 2 Below 2.0 points: 1

[0068] "Lack of filmy feeling" Five panelists applied 1.8 g of each mist-type hair cosmetic composition obtained in the Examples and Comparative Examples to half of a hair test doll (100% human black hair, model number: Queen Cut No. 775N, manufactured by Beaulux Co., Ltd.) and massaged it in with their hands. Then, the hair of the hair test doll was divided into 10 equal parts. One section of the hair was curled clockwise at a position 30 cm from the end using Babyliss Pro Miracurl (model number: BAB-2665-KJ, manufactured by Conair Japan, LLC) at 190°C for 8 seconds. This process was repeated for five separate sections. The five separate sections were evaluated for lack of filmy feel during and after hand-loosening using a sensory evaluation system on a 5-point scale of 5 (very good), 4 (good), 3 (fair), 2 (fair), and 1 (fail). The average score was calculated and then evaluated according to the following average score criteria. (Average score criteria) 4.0 points or above: 5 3.5 or above but below 4.0: 4 3.0 or above but below 3.5: 3 2.0 or more and less than 3.0: 2 Below 2.0 points: 1

[0069] "Keeping power" A tuft of human hair (100% black hair, model number: BS-A, manufactured by Bealux Co., Ltd.) was tied at the root with a rubber band to a length of 30 cm and a weight of 5 g. 0.15 g of the mist-type hair cosmetic composition obtained in the Examples and Comparative Examples was applied to the tuft and worked in with a comb. The tuft was then clamped with a Babyliss Pro Miracurl (model number: BAB-2665-KJ, manufactured by Conair Japan LLC) and curled clockwise at 190°C for 8 seconds. The length from the rubber band to the tip of the hair (L1) was measured. Hot air was then applied to the tuft from a distance of 30 cm using a hair dryer for 30 seconds, and the length from the rubber band to the tip of the tuft (L2) was measured again. The curl retention value was calculated using the following formula, and the average value for three tufts was calculated. The average value was then evaluated according to the following criteria. Note that a higher curl retention value indicates a smaller change in the curl of the tuft and better retention.

[0070] "Good cohesion" Five panelists applied 1.8 g of each mist-type hair cosmetic composition obtained in the Examples and Comparative Examples to half of a hair test doll (100% human black hair, model number: Queen Cut No. 775N, manufactured by Beaulux Co., Ltd.) and massaged it in with their hands. Then, the hair of the hair test doll was divided into 10 equal parts. One section of the hair was curled clockwise at a position 30 cm from the end using Babyliss Pro Miracurl (model number: BAB-2665-KJ, manufactured by Conair Japan, LLC) at 190°C for 8 seconds. This process was repeated for five separate sections. The five separate sections were then disentangled by hand and evaluated for manageability using a sensory scale of 5 (very good), 4 (good), 3 (fair), 2 (fair), and 1 (fail). The average score was calculated and then judged according to the following average score rating criteria. (Average score criteria) 4.0 points or above: 5 3.5 or above but below 4.0: 4 3.0 or above but below 3.5: 3 2.0 or more and less than 3.0: 2 Below 2.0 points: 1

[0071] "Gloss" Five panelists applied 1.8 g of each mist-type hair cosmetic composition obtained in the Examples and Comparative Examples to half of a hair test doll (100% human black hair, model number: Queen Cut No. 775N, manufactured by Beaulux Co., Ltd.) and massaged it in with their hands.

One section of the hair was curled clockwise at a position 30 cm from the end using Babyliss Pro Miracurl (model number: BAB-2665-KJ, manufactured by Conair Japan, LLC) at 190°C for 8 seconds. This process was repeated for five separate sections. After loosening the five sections by hand, the panelists evaluated the glossiness of the hair using a sensory scale of 5 (very good), 4 (good), 3 (fairly good), 2 (fairly poor), and 1 (poor), with a glossy impression being considered good. The average score was calculated and then judged according to the following criteria: (Average score criteria) 4.0 points or above: 5 3.5 or above but below 4.0: 4 3.0 or above but below 3.5: 3 2.0 or more and less than 3.0: 2 Below 2.0 points: 1
