Description

The present invention relates to a hair quality improving agent and the like for improving the firmness and stiffness of hair. The present invention is widely used for hair cosmetics and the like.

  The hair is damaged by daily hair care and hair makeup behavior.

  In particular, chemical treatment such as hair color, perm, bleaching, etc. promotes elution and structural change of hair constituent proteins, or surfactants that are the main components in shampooing and other shampooing activities can reduce hair lipids and hair constituent proteins. Dissolves and spurs hair damage.

  Such weakened hair and hair that has become thin and soft due to changes due to aging have a problem that styling is difficult because there is no firmness, volume, or volume.

  Therefore, attempts have been made to improve elasticity and stiffness by giving cysteine, cystine, and similar sulfur-containing compounds from the outside to the hair.

  Since cystine and cysteine contain a sulfur atom in their chemical structure, they are expected to exhibit physicochemical properties such as hair elasticity and stiffness improvement, biological activity, and the like different from other amino acids.

  In Patent Document 1, the combination of acetylcysteine and a copolymer containing 2-methacryloyloxyethyl phosphorylcholine monomer protects hair from damage, and has the effect of providing firmness, firmness, and coherent hair. Further, a technique for providing an excellent hair cosmetic is disclosed.

On the other hand, Junsai (Brasenia schreberi) is a major ingredient in Santan-cho, Akita Prefecture. The figure of picking up young shoots with a big tub in Junsai Marsh is an early summer feature. Junsai has a good texture because it is covered with a gel-like mucus that is rich in polysaccharides. In addition, since it is low in calories, it is also gaining recognition as a healthy food.

Hereinafter, the present invention will be described based on examples.
Example: Preparation of Junsai mucilage Junsen Brasenia schreberi (Cabombaceae) When extracting gel-like mucilage around leaves, water was first added to Junsai and autoclave treatment (121 ° C, 15 minutes) followed by filtration to obtain a filtrate. It was. The filtrate was concentrated, the concentrated solution was slowly added into cold ethanol, and a viscous substance was precipitated by ethanol precipitation. The deposited mucilage was collected and dried to obtain Junsai mucilage. After the obtained Junsai mucilage was dissolved in water, propanediol was added to a final concentration of 30% to obtain a Junsai mucilage solution having a final concentration of Junsai of 0.5%.

Test example: Evaluation of hair quality improving effect of Junsai mucilage Test method (1) Preparation of hair sample Human hair black hair bundle (1g × 10cm, Beaulux) is immersed in polyoxyethylene lauryl ether sodium sulfate aqueous solution (solid content 2.0%) for 30 minutes at 40 ° C, washed with running water, and then drier The dried hair is used as healthy hair.
As a damage treatment, the hair sample subjected to the above washing treatment is immersed in 1.5% ammonia-containing 1.5% hydrogen peroxide solution at 30 ° C. for 40 minutes, washed with running water, and then dried with a drier. This damage treatment was repeated three times to create damaged hair.

(2) Sample solution In this test example, the following sample solutions were used.
Example 1: 30% propanediol aqueous solution containing 5% Junsai mucilage solution prepared according to the above example Comparative Example 1: 30% propanediol aqueous solution containing 0.025% hydroxyethylcellulose (HEC) Example 2: Above Example Example Junsai mucilage solution comparative example 2: 30% propanediol aqueous solution containing 0.5% hydroxyethyl cellulose (HEC)

(3) Preparation of leave-on hair Each sample hair was prepared by immersing damaged hair in the sample solution of Example 1 at 40 ° C. for 10 minutes, drying with a dryer, and hanging overnight at room temperature. As a control, damaged hair was immersed in water and dried with a dryer.

(4) Preparation of rinse-off hair Damaged hair was immersed in the sample solution at 40 ° C. for 10 minutes, washed with running water, dried with a dryer, and suspended overnight at room temperature to prepare each sample hair. As a control, damaged hair was immersed in water, washed with running water, and then dried with a dryer.

(5) Method for measuring elasticity and stiffness of hair The elasticity and stiffness of the leave-on hair and rinse-off hair were evaluated by the following methods.
That is, 20 hairs were arranged at 1 mm intervals, and using a pure bending tester KES-FB2, the bending hardness (harness) and the bending recovery property (koshi) were measured.

(6) Method of observing unity feeling The unity feeling of leave-on hair was evaluated by the following method.
That is, each hair bundle was suspended, visually observed, and photographed.

(7) Method for measuring tensile strength The tensile strength of rinse-off hair was evaluated by the following method.
The tensile strength per hair was measured using a tensile tester Autograph AG-500C. During the measurement, the thickness of each hair was measured and the strength per cross-sectional area was calculated.

2. Results and Effects of Examples The results for leave-on hair are shown in FIG. 1 (harness) and FIG. 2 (koshi). Moreover, the photograph of the hair | bristle bundle of leave-on hair is shown in FIG. As shown in FIG. 1 and FIG. 2, the firmness and firmness of the hair decreased by performing the damage treatment, but the firmness and firmness improved by being immersed in the 3% aqueous solution of Junsai mucilage solution. In addition, as shown in FIG. 3, the damaged hair also had a large spread of hair, but the spread was suppressed by the 3% Junsai mucilage solution.
The results for the rinse-off hair are shown in FIG. 4 (harness), FIG. 5 (koshi) and FIG. 6 (tensile strength). As shown in FIGS. 4 and 5, Junsai mucilage solution 5% solution improved hair firmness and stiffness. Furthermore, as shown in FIG. 6, the Junsai mucilage solution improved the tensile strength of the hair. Moreover, when compared with HEC, which is a thickener, Junsai mucilage solution improved hair quality over HEC.
From the above, it was confirmed that Junsai mucilage can be used as an excellent hair quality improver and can be used as a hair cosmetic raw material.
