Description

The present invention relates to a hair cleansing composition that imparts elasticity to dried hair, increases the volume, and maintains a smooth feel from the time of washing the hair to the time of drying.

Hair becomes thinner with aging, and the loss of elasticity increases the problem of volume reduction. In addition, the surface of the hair is also roughened, which raises the awareness of damage. In response to these concerns, in recent years there has been an increasing demand for hair shampoos that appeal to the elderly to increase the volume of their hair. However, hair shampoo alone is not effective enough, and it is actually used in combination with conditioners and care agents that do not wash away. In addition, arginine is generally widely used as a component that gives hair elasticity and increases volume. Arginine is known to have the effect of penetrating into the hair, giving it firmness and increasing its volume. However, it has no effect on the surface of the hair, and although it increases the volume, the hair feels rough, and as a result, it is used in combination with a conditioner and a care agent that does not wash away. Therefore, a derivative of arginine has been studied, and a base has been proposed that not only gives elasticity and increases volume, but also improves the feel of the hair surface (Patent Document 1). However, there are cases where the hair shampoo alone does not improve the feeling of satisfaction, and there are cases where a conditioner containing the arginine derivative is used in combination.

Providing a hair cleansing composition that gives hair firmness and volume with just a hair shampoo, and gives a smooth feel from the time of washing to the time of drying.

The present inventors make full use of the performance of the arginine derivative described in Patent Document 1, and have a smooth feel from the time of washing the hair to after drying, and do not need to use a conditioner or a non-rinse treatment. The composition was diligently examined. As a result, among the arginine derivatives described in Patent Document 1, a certain amount of succinyl arginine Na was added and a specific composition was obtained to achieve both performance.

Why is succinyl arginine Na able to give elasticity to the hair and increase the volume, and also to have a smooth feel from the time of washing the hair to after drying? TOF-SIMS (ION-TOF, TOF) .SIMS ⁵ , Toray Research Center Co., Ltd. was requested to measure) (Fig. 1). It shows that succinyl arginine Na is present in the white part. As a result, it was found that succinylarginine Na was present on the surface and inside of the hair. On the other hand, it was found that arginine is present only inside the hair (Fig. 2). It shows that arginine is present in the white part. It is widely known that arginine gives elasticity to hair, and it is presumed that it modifies the internal structure, but it is not adsorbed on the hair surface and the hair surface is not modified. This difference leads to the effect that succinyl arginine Na not only gives elasticity and increases volume, but also improves the feel of the hair surface. However, in the rinsing after washing the hair, the succinyl arginine Na adsorbed on the hair surface may be washed away, and the hair shampoo alone may not improve the satisfactory feel. Therefore, we diligently studied a specific formulation in which succinyl arginine Na stays on the hair surface even during rinsing and continues to have a smooth feel even after drying.

As a result of diligent studies, we have found a means to solve the problem by combining coacervates generated in specific components. It is known that coacervate is generated by combining a specific cationic polymer and a specific amphoteric surfactant (Non-Patent Document 1). The coacervate is an insoluble complex formed when the number of ions of the surfactant / the degree of polymerization of the polymer becomes 1 when the charged surfactant and the cationic polymer coexist in the aqueous solution. It is also known that coacervates occur during rinsing and remain in the hair (Non-Patent Document 2). That is, they have found that coacervates are generated during rinsing, and the coacervates are adsorbed on the hair surface to prevent succinylarginine Na from being washed away from the hair surface, and a smooth feel is maintained until after drying, and the present invention has been made.

That is, the present invention
(A) Succinylarginine Na represented by the general formula (1) 0.1 to 10.0% by weight
(B) Specific cationic polymer (polyquaternium-10, at least one of guarhydroxypropyltrimonium chloride) 0.3 to 0.8% by weight
(C) Amphoteric tenside agent that produces coacervate in the dilution process when mixed with the components (B) 2.0 to 10.0% by weight
It is a hair cleansing composition which is the composition of.

The present invention contains an arginine derivative having excellent performance, and further contains a specific cationic polymer and a specific amphoteric surfactant to give the hair firmness and a smooth feel from washing to drying. It is excellent as a hair cleansing composition because it has a satisfactory performance without using a conditioner or the like.

FIG. 1 shows the TOF-SIMS measurement results of succinylarginine Na. FIG. 2 shows the TOF-SIMS measurement results of arginine.

Production example (Production of succinylarginine Na)
190 g of distilled water was added to a 500 ml four-necked flask, 53.8 g of L- (+)-arginine (Tokyo Chemical Industry Co., Ltd.) was added to a place heated to 40 ° C., and the mixture was completely dissolved by stirring. .. Succinic anhydride (30.9 g, 1 equivalent, Tokyo Chemical Industry Co., Ltd.) was added thereto. Since the pH drops after the addition of succinic anhydride, a 48 wt% aqueous solution (25.7 g, 1 equivalent) of NaOH (Tokyo Kasei Kogyo Co., Ltd.) was added dropwise so that the pH became 6-9, and succinic anhydride was added. Was completely dissolved and stirred until the pH became stable at around 6, to obtain the desired product. The structure of the target product ^{was confirmed by 1} H-NMR (JEOL Ltd., JNM-ECZ400S). ^{1 1} H-NMR chemical shift: 1.5 to 1.8 ppm (4 H m), 2.3 ppm (4 H m), 3.1 ppm (2 H m), 4.1 ppm (1 H m). The contents of succinic acid and arginine were quantified by high performance liquid chromatography (column: GL Sciences Co., Ltd., Inertsil® ODS-2, 250 mm). It was 0.4% by weight and 0.2% by weight, respectively.

Test Method The hair cleansing composition having the composition shown in Tables 1 and 2 was prepared according to a conventional method to obtain the hair cleansing composition described in Examples 1 to 6 and Comparative Examples 1 to 11. The following evaluation was performed on the obtained hair cleansing composition. The results are shown in Tables 1 and 2.

1. 1. Measurement method of core selvate confirmation test The turbidity (white balance) of the samples prepared according to the examples and comparative examples in Tables 1 and 2 and their turbidity (white balance) when diluted 20-fold by weight with purified water is measured by a spectroscopic color difference meter (Japan). It was measured by Nippon Denshoku Industries Co., Ltd., Spectrophotometer SE2000). The formation of coacervates was confirmed from the fluctuation of white balance when diluted.
<Confirmation criteria for coacervate>
○: Cloudy (increased white balance)
×: Transparent (no change in white balance)
A case of ◯ indicates that a coacervate has been generated, and a case of × indicates that a coacervate has not been generated.

2. The smoothness of the hair during washing was judged by the following sensory evaluation.
The smoothness of the hair during washing was evaluated. Six professional panelists used the example and comparative hair cleansing compositions for 5 days and smoothed the hair during washing: 5 points, slightly smoothed: 4 points, changed. No: 3 points, slightly rough: 2 points, rough: 1 point, judged by a 5-step evaluation, and the average was shown as a result. The closer it is to 5 points, the smoother it is.

3. 3. Measurement of Hair Smoothness After Drying The bleached hair obtained by bleaching human hair (Burex Co., Ltd., Hair Strand 5 Black Hair 100% Root Alignment) was divided into four parts to make the length 10 cm. The hair was allowed to stand in a constant temperature and humidity chamber at room temperature of 20 ° C. and humidity of 60% for 6 days, and the smoothness of the hair after drying was measured by a friction tester (Kato Tech Co., Ltd., KESSE-STP type). A hair bundle was attached to the testing machine, and the average coefficient of friction (MIU value) when rubbed with a 10 mm square piano wire sensor contactor was measured. The measurement conditions are vertical load: 25 g, speed: 0.5 mm · s ^-1 .
Further, the samples prepared according to Examples and Comparative Examples were washed 10 times and rinsed with distilled water, and the hair was allowed to stand in a constant temperature and humidity chamber at room temperature of 20 ° C. and humidity of 60% for 6 days as described above. The MIU value was measured under the same conditions. The change in the MIU value after the treatment with respect to the MIU value before the treatment was set to 100% before the treatment, and Tables 1 and 2 show the rate of change as to how much the change was after the treatment. When the rate of change of the MIU value is −, the hair surface is smooth, and when +, it indicates that the hair surface is rough. The smaller the number, the smoother it is.

4. Measurement of firmness of dried hair The bleached hair bleached with human hair (Burex Co., Ltd., Hair Strand 5 100% black hair root alignment) was divided into four parts to make the length 10 cm. The mixture was allowed to stand in a constant temperature and humidity chamber at room temperature of 20 ° C. and humidity of 60% for 6 days, and the rate of change in bending hardness was measured by a pure bending tester (Kato Tech Co., Ltd., KESFB2-S type). The central part of the hair bundle was attached to the testing machine, and the bending stress was measured in the range of ^{curvature (K) -1.5 to +1.5 cm -1 at} a rate of change ^{of 0.5 cm -1} · s ^-1. bending stress - K in curvature curve: the flexural properties were measured from the slope of the curve between 0.5 to 1.0 cm ^-1 and -0.5~1.0cm ^-1. Further, the samples prepared according to Examples and Comparative Examples were washed 10 times and rinsed with distilled water, and the hair was allowed to stand in a constant temperature and humidity chamber at room temperature of 20 ° C. and humidity of 60% for 6 days as described above. Bending characteristics were measured under the same conditions. Tables 1 and 2 show the change in the bending characteristic value after the treatment with respect to the bending characteristic value before the treatment as 100% before the treatment and how much the change was after the treatment. As a calculation example, in the case of Example 1, the slope before the treatment is 2.35, the slope after the treatment is 2.59, and the rate of change = 2.59 / 2.35 × 100 = 110.2. Therefore, it is shown that the elasticity of the hair is improved by + 10.2% after the treatment as compared with before the treatment. If the rate of change of the bending characteristic value is +, the elasticity is improved, and if it is −, the elasticity is decreased. The larger the number, the more elastic it is.

As a result of the evaluation, Examples 1 to 6 prepared within the range of the hair cleansing composition of the present invention maintained a smooth feel from washing to drying, and increased the elasticity after drying. On the other hand, in Comparative Examples 1 to 11 which were out of the range, one of the feelings was lowered. In particular, the firmness of arginine having similar characteristics was confirmed, but the smoothness was poor (Comparative Example 2), and the smoothness of succinic acid was good, but the firmness did not have sufficient performance (Comparative Example 3). Furthermore, it was also confirmed that the addition of both arginine and succinic acid reduced the effect of firmness (Comparative Example 4). It can be inferred that succinic acid is first adsorbed on the hair surface and hinders the penetration of arginine. On the other hand, the component (A) exists on the surface and inside of the hair, and can be said to be a component capable of achieving both performance. In addition, it is important to protect the hair surface by coacervate during rinsing in order to maintain the performance, and the combination of the present invention can satisfy the satisfactory performance.

With the hair cleansing composition of the present invention, it is possible to give elasticity to the hair after drying, increase the volume, and maintain a smooth feel from the time of washing the hair to the time of drying. Can be enhanced.
