Description

[Technical Field]

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

[0002] In recent years, in addition to chemical treatments such as hair coloring and perms, it has become a habit, especially among young women. Hair styling using heat from hair irons, hair dryers, etc. can cause hair to dry out, especially at the ends. Hair damage is caused by 18-MEA, a fatty acid that covers the surface of the hair. With the loss of 18-methyleicosanoic acid, the hair surface becomes hydrophilic and the surface friction increases. It has been reported that the accumulation of such damage can cause When using a ring, the ends of your hair get tangled, making it difficult to style your hair as you want, and making it difficult to run your fingers through. This is a major concern for consumers.

[0003] For this reason, there is a need for technology that can restore the hydrophobicity and low friction inherent in healthy hair. One such technique is to apply a strong polymer to the surface of damaged, hydrophilic hair. -Several hair cosmetics have been proposed that can form a film and restore lost hydrophobicity. It has been done.

[0004] For example, Patent Document 1 discloses a (meth)acrylic resin having a silyl group to which a reactive functional group is bonded. A copolymer consisting of acid ester monomers is hydrolyzed on the hair to crosslink it. This technique forms a crosslinked coating film with excellent washing resistance.

[0005] Patent Document 2 also describes a method for producing a compound having a specific oxirane or oxetane compound and a specific aminosilane. Personal care compositions containing reaction products (epoxyaminosilane copolymers) with compounds Some techniques have been disclosed for forming a hydrophobic film that is durable against washing. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] International Publication No. 98 / 54255 Brochure [Patent Document 2] Special Publication No. 2011-503059 Summary of the Invention [Problem to be solved by the invention]

[0007] However, the technology described in Patent Document 1 has a drawback in that it prevents cross-linking of the copolymer during storage. It must be kept away from water until use, and therefore requires a hydrolysis step for cross-linking. The process must be carried out immediately before use and must be user-friendly for the consumer. It wasn't.

[0008] In addition, the technique described in Patent Document 2 is a simpler method, but it requires immersing the hair in a high bath ratio. Only after processing and allowing sufficient drying time can the material achieve its washability. Therefore, the effect was not obtained by leave-on treatment with a low liquor ratio. It is simple and effective, and meets the needs of today's consumers with only a small amount of treatment in a short time. It wasn't.

[0009] Therefore, the present invention provides a method for imparting sufficient hydrophobicity to hair by applying a low liquor ratio and a short time to the hair. It provides a low friction effect and also helps separate hair bundles during the drying process, making it easy to run your fingers through while drying. It is easy to use, and the hair is less sticky on the fingers after drying, and the hair is easy to manage after drying. A hair cosmetic that maintains its effects for a long time, even after repeated hair treatments and washing. Regarding fees. [Means for solving the problem]

[0010] As a result of extensive research, the present inventors have found that a self-crosslinking compound and an IOB in the organic conceptual diagram are The above problem can be solved by using a compound that has a viscosity of 0.3 or less and is liquid at 20°C. We have discovered this and completed the present invention.

[0011] The present invention comprises the following components (A) and (B), and the content of component (A) is 0.05 mass% or more and 10 mass% or less. % or less, and the content of component (B) is 5% by mass or more and 99.9% by mass or less. That is why. (A) Self-crosslinking compound (B) A compound whose IOB in the organic conceptual diagram is 1.3 or less and is liquid at 20°C

[0012] Furthermore, the present invention provides a hair care method in which the hair cosmetic composition is applied to hair and then dried without rinsing. The present invention provides a method for using cosmetics. [Effects of the Invention]

[0013] The hair cosmetic composition of the present invention can be applied to hair at a low liquor ratio for a short time to achieve sufficient hydrophobicity. It provides a good effect of providing hair with good hair flow and reducing friction, and also helps to separate hair bundles during the drying process, making it easy to run your fingers through while drying. The hair is less sticky on the fingers after drying, and the hair is easy to manage after drying. These effects can be maintained for a long time even after repeated washing. can.

[0093] Examples 1 to 21, Comparative Examples 1 to 5 Oily hair cosmetics having the compositions shown in Tables 1 and 2 were prepared, and the hair was treated with these. Regarding this, we measured the advancing contact angle of hair with water and combing force, and performed various sensory evaluations. It was.

[0094] (Processing method) The hair samples used for evaluation were all healthy Japanese hair samples of 5.0g each, bleached once and washed 360 times. Damaged hair that had been turned over was used. The oily hair cosmetic compositions of each Example and Comparative Example were applied to hair according to the bath ratios shown in the table, and then left to stand for 1 hour without rinsing. Then, the hair was thoroughly dried using a hair dryer. After washing once and drying, the result was counted as one wash, and after washing and drying 20 times, the result was counted as 20 washes. This was after the session. In Comparative Example 5, untreated damaged hair was washed once with plain shampoo and then dried. The dried hair was used for evaluation (no evaluation was performed after 20 hair washes).

[0096] (advancing contact angle of hair) The advancing contact angle of the hair with water was measured and used as the contact angle value. Using the KRUSS GmbH Processor Tensiometer K100, the surface tension of water was 72.8 mN / m. Density: 0.998g / cm 3 , Maximum Immersion Depth:4mm, Minimum Immersion Depth:1mm, Measurement Measurements were taken at a constant speed of 2 mm / min. Five strands of hair were taken from each treatment. The area 5 cm from the base was used for measurement, and the average value of the five was taken as the contact angle. When the angle is above 90°, the higher the angle, the more hydrophobic it is. In other words, the higher the value is above 90°, the more hydrophobic it is. This indicates that the specified processing has been completed.

[0097] (Combing Force) After rinsing the hair with warm water at 40°C for 15 seconds, the combing force was measured using a dynamic comb. Force method (Suzuki et al.; J. Soc. Cosmet. Chem. Japan. Vol. 27, No. 1, P11-13 1993) The average of 10 measurements (maximum value) was used. The smaller this value, the easier it is to comb. This indicates that the surface is smooth and not sloping.

[0098] (sensory evaluation) "The hair clumps come apart easily during the drying process," "The hair feels smooth to the touch while drying," and "The hair feels smooth to the touch after drying." Seven expert panelists evaluated the following items: "low stickiness on hair" and "speed of hair drying" The evaluation was conducted using the following five-point scale, and the total score was used to make a judgment.

[0099] "The hair strands come apart easily during the drying process." 1: Very poor dispersion 2: Poor dispersion 3: Neither 4: Good dispersion 5: Very good dispersion

[0100] "Smoothness of fingers when drying" 1: It's very hard to run your fingers through 2: It's hard to run your fingers through 3: Neither 4: Easy to run your fingers through 5: Very smooth to the touch
