Description

  The present invention relates to a hair treatment agent.

  The hair is damaged by, for example, exposure to ultraviolet rays and drying with a dryer. In recent years, with the generalization of chemical treatments such as perm, decoloring, and dyeing on hair, awareness of hair damage has increased. Damaged hair has less firmness, firmness and gloss than normal hair, and feels bad. In addition, the damaged hair has a low barrier function because the water repellency is lower than that of healthy hair.

  Therefore, a hair treatment agent containing silicone oil as a component for covering the surface of hair has been proposed (see, for example, Patent Document 1). The silicone oil is believed to improve the firmness, stiffness, gloss and feel of damaged hair by covering the surface of the hair.

  However, since the silicone oil is difficult to penetrate into the hair, the hair treatment agent containing the silicone oil has only a temporary effect of improving the firmness, stiffness, gloss and feel on the damaged hair. There is a disadvantage that it cannot be obtained.

Examples 1-3 and Comparative Examples 1-5
Behenic acid amide (Examples 1 to 3), N-stearyl erucamide (Comparative Example 2), lauric acid amide (Comparative Example 3), N-stearyl oleic acid amide (Comparative Example 4) or methylpolysiloxane (Comparative Example 5) ), Sorbitan monostearate, cetanol, dimethylaminopropylamide stearate, glycerin, liquid paraffin, phenoxyethanol, lactic acid, and purified water after mixing to the composition shown in Table 2. The resulting mixed solution was emulsified to obtain a treatment as a hair treatment agent. Further, after mixing sorbitan monostearate, cetanol, dimethylaminopropylamide stearate, glycerin, liquid paraffin, phenoxyethanol, lactic acid, and purified water so as to have the composition shown in Table 2, The obtained liquid mixture was emulsified to obtain a treatment as a hair treatment agent (Comparative Example 1). In Table 2, the amount of each compounding component is a value converted to a pure component.

Test example 1
(1) Preparation of sample for mass microscope The treatment obtained in Example 1 was diluted 10 times with purified water to obtain a treatment dilution. The bleached hair obtained in Preparation Example 2 was immersed in the treatment dilution obtained at 35 ° C. for 5 minutes. Next, the treatment dilution adhering to the surface of the hair after immersion was washed away in running tap water of about 40 ° C. Thereafter, the hair was washed with tap water for 30 seconds so as not to apply tension to the hair. The washed hair was naturally dried to obtain treatment-treated hair.

  Each of the untreated hair obtained in Preparation Example 1, the bleached hair obtained in Preparation Example 2 and the treatment-treated hair was embedded according to the freezing embedding method to obtain an embedded sample. A cross section of the embedded sample was prepared using a cryostat. After the transverse section was adhered on a slide glass, a matrix (gentisic acid) was deposited on the transverse section to obtain a sample for mass microscope.

(2) Observation of sample by mass microscope and mass analysis The sample for mass microscope obtained in Test Example 1 (1) was subjected to an imaging mass microscope [manufactured by Shimadzu Corporation, trade name: iMSscope] for the mass microscope. While observing the sample under the optical microscope, the mass spectrum in the range of m / z = 200-1500 was measured about the sample for the mass microscope. The analysis conditions are as follows.

<Analysis conditions>
Ionization method: Matrix-assisted laser desorption ionization method Measurement mode: Positive ion measurement mode Laser intensity: 30%
Laser repetition frequency: 1000 Hz
Mass spectrometer: quadrupole ion trap time-of-flight mass spectrometer

  The obtained measurement results were analyzed using analysis software [manufactured by Shimadzu Corporation, trade name: Imaging MS Solution]. Based on the obtained optical microscope images, regions of interest (hereinafter also referred to as “ROI”) were set on the surface layer of each of the bleached hair, the untreated hair, and the treated hair, and the behenic acid amide peak was extracted. The content of behenic acid amide in the hair was examined by measuring the average intensity of the signal derived from the behenic acid amide per unit area of the ROI of each of the bleached hair, the untreated hair, and the treated hair.

  In Test Example 1, the results of examining the content of behenic acid amide in the hair are shown in FIG. In the figure, lane 1 shows the content of behenic acid amide in the bleached hair, lane 2 shows the content of behenic acid amide in the untreated hair, and lane 3 shows the content of behenic acid amide in the treated hair.

  From the results shown in FIG. 1, the content of behenic acid amide in the treated hair (lane 3) is compared with the content of behenic acid amide in each of the bleached hair (lane 1) and the untreated hair (lane 2). It can be seen that the number is significantly higher. Therefore, it can be seen from this result that the behenic acid amide permeates into the hair damaged by the bleaching when the bleaching hair is treated using the treatment obtained in Example 1.

Test example 2
(1) Preparation of treatment-treated hair The treatment obtained in Example 1, which is a test sample, was diluted 10 times with purified water to obtain a diluted treatment. The bleached hair obtained in Preparation Example 2 was immersed in the treatment dilution obtained at 35 ° C. for 30 minutes. Next, the treatment dilution adhering to the surface of the hair after immersion was washed away in running tap water of about 40 ° C. Thereafter, the hair was washed with tap water for 30 seconds so as not to apply tension to the hair. The washed hair was naturally dried to obtain treatment-treated hair.

  Moreover, in the above, it was the same as above except that each of the treatments obtained in Examples 2-3 and Comparative Examples 1-5 was used as the test sample instead of using the treatment obtained in Example 1. Operation was performed to obtain treatment-treated hair.

(2) Preparation of sample for measurement The treatment-treated hair (length 30 mm) obtained in Test Example 2 (1) was allowed to stand for 48 hours or more in a constant temperature and humidity chamber maintained at 23 ° C. at 60% relative humidity. . Next, both ends of the treatment-treated hair were fixed to obtain a measurement sample.

  In addition, in the above description, instead of using the treatment-treated hair obtained in Test Example 2 (1), the untreated hair (length 30 mm) obtained in Preparation Example 1 or the bleach-treated hair (long hair obtained in Preparation Example 2) The sample for measurement was obtained by performing the same operation as described above except that 30 mm was used.

(3) Measurement of contact angle between hair and water Using the automatic contact angle meter (trade name: DM-500, manufactured by Kyowa Interface Science Co., Ltd.), the measurement sample obtained in Test Example 2 (2) was not used. Purified water (0.5 μL) was dropped at two locations for each treated hair. Next, using the multifunctional integrated analysis software [trade name: FAMAS (interface measurement & analysis system)] of the automatic contact angle meter, an automatic contact angle meter (trade name: DM-500, manufactured by Kyowa Interface Science Co., Ltd.) and water By measuring the angle between the hair and the water droplet when 61 seconds have passed after the dripping, and calculating the average value of the angles measured at the two locations of the hair, thereby bringing the hair into contact with water. I asked for a corner. The contact angle was measured under constant conditions of constant temperature and humidity at 23 ° C. and a relative humidity of 60%.

  In Test Example 2, the results of examining the relationship between the type of test sample and the contact angle are shown in FIG. In the figure, lane 1 is the contact angle between the treatment-treated hair treated with the treatment obtained in Example 1 and water, and lane 2 is the treatment-treated hair treated with the treatment obtained in Example 2 and water. The contact angle, lane 3 is the contact angle between the treatment-treated hair treated with the treatment obtained in Example 3 and water, and lane 4 is the treatment-treated hair treated with the treatment obtained in Comparative Example 1 and water. The contact angle, lane 5 is the contact angle between the treatment-treated hair treated with the treatment obtained in Comparative Example 2 and water, and lane 6 is the treatment-treated hair treated with the treatment obtained in Comparative Example 3 and water. Contact angle, lane 7 is the contact angle between the treatment-treated hair treated with the treatment obtained in Comparative Example 4 and water, and lane 8 is the contact angle obtained in Comparative Example 5. The contact angle between the treatment-treated hair treated with the treatment and the water, lane 9 is the contact angle between the bleached hair obtained in Preparation Example 2 and water, and the lane 10 is the untreated hair obtained in Preparation Example 1 and water. The contact angle with is shown.

  The results shown in FIG. 2 indicate that the contact angle between the treatment-treated hair treated with the treatments obtained in Examples 1 to 3 and water is larger than the contact angle between the bleach-treated hair and water. . On the other hand, it can be seen that the contact angle between the treatment-treated hair treated with the treatments obtained in Comparative Examples 1 to 5 and water is approximately the same as the contact angle between the bleach-treated hair and water. From these results, according to the treatments obtained in Examples 1 to 3, the water repellency of the damaged hair surface can be further improved as compared with the treatments obtained in Comparative Examples 1 to 5. I understand. Therefore, from these results, according to the treatments obtained in Examples 1 to 3, compared with the treatments obtained in Comparative Examples 1 to 5, the hair surface barrier function is further improved, and hair damage is reduced. It is suggested that progression can be suppressed.

  The treatments obtained in Examples 1 to 3 have different behenic acid amide contents. However, the contact angle between the treatment-treated hair treated with the treatment obtained in Examples 1 to 3 in which the content of behenic acid amide is 0.25 to 1.00% by mass and water is the content of behenic acid amide. It can be seen that there is almost no difference due to the difference in quantity.

  The behenic acid amide contained in the treatments obtained in Examples 1 to 3 penetrates into the surface layer of hair. On the other hand, methylpolysiloxane contained in the treatment obtained in Comparative Example 5 does not penetrate into the surface layer of hair. Therefore, it is suggested that the hair treatment agent containing behenic acid amide can repair damaged hair more efficiently than the hair treatment agent containing silicone oil such as methylpolysiloxane.

  Therefore, from these results, according to the hair treatment agent containing behenic acid amide, it is possible to improve the hair barrier function and suppress the progress of hair damage, and to efficiently repair damaged hair. It is suggested that you can.

Test example 3
Surfactant 3.0g shown in Table 3 and glycerin 3.0g were added to a 30 mL capacity screw tube. The obtained mixture was heated to 85 to 90 ° C., and 0.5 g of behenic acid amide was added to the mixture. Thereafter, the obtained mixture was allowed to stand for 30 minutes or more, the properties of the mixture were visually observed, and the solubility of behenic acid amide in the surfactant was evaluated based on the following evaluation criteria.
<Evaluation criteria>
AA: Insoluble matter is not visually observed, and the whole is uniform.
A: Insoluble matter having a size that can be visually observed or cannot be confirmed is confirmed.
B: Insoluble matter that can be visually observed is confirmed.
C: The amount of insoluble matter that can be visually observed is large.
D: The amount of insoluble matter that can be visually observed is very large.

  In Test Example 3, the results of evaluating the solubility of behenic acid amide in the surfactant are shown in Table 3.

  From the results shown in Table 3, polyoxyethylene glyceryl monoisostearate (experiment number: 1), decaglyceryl monoisostearate (experiment number: 2), monostearic acid having an average addition mole number of oxyethylene groups of 8 According to sorbitan (experiment number: 3), polyoxyethylene stearyl ether (experiment number: 4) and coconut oil fatty acid monoethanolamide (experiment number: 5) having an average added mole number of oxyethylene groups of 2, behenic acid It can be seen that the amide can be dissolved. Especially, according to sorbitan monostearate (experiment number: 3) and coconut oil fatty acid monoethanolamide (experiment number: 5), it turns out that behenic acid amide can be dissolved more favorably.

  Therefore, from these results, the average addition moles of behenic acid amide and polyoxyethylene glyceryl monoisostearate, decaglyceryl monoisostearate, sorbitan monostearate, and oxyethylene groups having an average addition mole number of oxyethylene groups of 8 By using together with at least one nonionic surfactant selected from the group consisting of polyoxyethylene stearyl ether and coconut oil fatty acid monoethanolamide having a number of 2, the behenic acid amide is converted into the nonionic surfactant. Since it can be dissolved in an agent, it is suggested that it can be easily formulated.

Examples 4-7
In Example 1, instead of using sorbitan monostearate, polyoxyethylene glyceryl monoisostearate having an average number of added oxyethylene groups of 8 (Example 4), decaglyceryl monoisostearate (Example 5), The same operation as in Example 1 was performed except that polyoxyethylene stearyl ether (Example 6) or coconut oil fatty acid monoethanolamide (Example 7) having an average addition mole number of oxyethylene groups of 2 was used. Get a treatment.

  Next, in Test Example 1, instead of using the treatment obtained in Example 1, the treatment obtained in Examples 4 to 7 was used to examine the content of behenic acid amide in the hair. As a result, by treating the damaged hair with the treatments obtained in Examples 4 to 7, behenic acid was added to the damaged hair in the same manner as the treatment obtained in Example 1. There is a tendency for amides to penetrate.

  Further, in Test Example 2, instead of using the treatment obtained in Example 1, the treatment obtained in Examples 4 to 7 was used and the same operation as in Test Example 2 was performed, and the contact angle between hair and water Check out. As a result, the hair damaged by the hair was treated similarly to the treatment obtained in Example 1 by applying the treatment treatment to the bleached hair using the treatments obtained in Examples 4-7. There is a tendency to improve the water repellency of the surface. Therefore, according to the treatment obtained in Examples 4 to 7, it is suggested that the barrier function of the hair surface can be further improved and the progress of damage to the hair can be suppressed.

  As explained above, according to the hair treatment agent containing behenic acid amide, it is possible to improve the barrier property of the hair and suppress the progress of the damage of the hair, and efficiently repair the damaged hair. You can see that Therefore, it is expected that the hair treatment agent is suitably used for applications such as damage care.
