Description

  The present invention relates to a hair rinsing agent (treatment rinsing) that causes less discoloration of hair colored with hair color.

  Soap shampoo has a high alkalinity of pH 8 to 12, so if you wash your hair with soap shampoo, the hair cuticle will open. And it is known that the more painful the cuticle is, the more intense and stiff feeling is.

  Therefore, in order to forcibly close the cuticle which is opened to the alkali side by soap shampoo, it is neutralized with an acidic solution. Generally used for such neutralization is a rinse mainly made of vinegar such as citric acid or vinegar.

  However, rinsing using citric acid as a main raw material has a problem that the bleaching power is so strong that it can be used for kitchen cleaning, and the color of hair dye is easily lost. In other words, since the hair dyeing easily fades due to the bleaching action of the rinse, the frequency of hair dyeing increases and the hair dyeing cost increases accordingly, and the hair dyeing interval is shortened, and the hair dyeing is performed accordingly. There is a problem that it takes extra time.

  In recent years, many young women have dyed hair by coloring, as well as gray-hidden hair dyeing, and discoloration of hair dye by rinsing has been pointed out as a problem.

  Furthermore, since users who are concerned about soap are not concerned with addition, single-component rinses such as citric acid and vinegar are preferred, while vinegar rinses such as citric acid and vinegar smell the smell of vinegar. However, there was a problem that it was difficult to use.

  In view of the above-described problems of the prior art, an object of the present invention is to provide a new hair rinse agent that has less discoloration (hair dyeing loss) of hair colored with hair color and is easier to use than conventional citric acid rinses. It is to provide.

As a result of research by the inventors of the present application, a new treatment rinse that breaks the conventional common sense of “citrate rinse for soap” has been developed.
That is, the above-described object is achieved by a hair rinse agent mainly composed of Tamagawa Onsen source water (source water that springs at Tamagawa Onsen in Akita Prefecture). This hair rinse agent further contains one or more of honey, lavender extract and rosemary extract.

  The main raw material of the hair rinse agent of the present invention is source water that springs from a natural hot spring (source water that springs at Tamagawa Hot Spring in Akita Prefecture), which can contribute to solving food problems and manufacturing energy problems.

  The pH of the main raw material Tamagawa Onsen source water is 1.05, which is strongly acidic, and is more acidic than that of citric acid and vinegar.

  It is a hot spring source water and contains many minerals (components of Tamagawa hot spring source water are shown in FIG. 1). And it is a safe ingredient that can be drunk more than 10 times.

  The hair rinsing agent of the present invention had a 39.8% reduction in the degree of discoloration of the hair dye at the first time as compared with the conventional commercial citrate rinse. Furthermore, even on the 8th day, the reduction was 24.7%.

  By using the hair rinse agent of the present invention, the frequency of hair dyeing can be reduced. If the frequency of hair dyeing is reduced, the hair dyeing interval becomes longer, saving time and cost. That is, the cost for maintaining hair dyeing can be reduced.

  One-half to one-third of the amount of commercially available citrate rinse is sufficient. As a result, since the consumption amount of the rinse container to be sold can be reduced, non-burnable garbage can be reduced, contributing to the improvement of environmental pollution, and also contributing to resource saving and energy saving.

  The hair dye discoloration degree comparison experiment and results will be described later.

  The hair rinsing agent (treatment rinse) of the present invention contains, as a main raw material, source spring water (Tamagawa Onsen source spring water) that springs out at Tamagawa Onsen.

  Tamagawa Onsen is a hot spring in Senboku City, Akita Prefecture, and the source water that springs from it contains the components shown in FIG.

  Tamagawa Onsen source water is rich in minerals, has a pH of 1.01 and is a highly acidic, safe ingredient for bathing in hot springs. In addition, the cuticle of the open hair is closed to neutralize the hair and scalp leaning to the alkali side. Furthermore, there is an effect that the scalp is adjusted to the same weak acidity (PH value 3.5 to 6.0) as healthy bare skin.

  Moreover, the hair rinse agent of this invention contains any 1 type, or 2 or more types of a honey, a lavender extract, and a rosemary extract besides the Tamagawa hot spring source water mentioned above. Although the kind of honey is not specifically limited, Manuka honey is especially preferable.

Honey (Manuka Honey) has a moisturizing action and moisturizes hair.
Honey is acidic (pH 3.2 to 4.5), and the strongly acidic pH of the source water can be raised somewhat to the alkali side.

Lavender extract removes the scent of hot spring water and turns it into a pleasant scent of herbs.
Lavender extract is an (aromatic) oil collected from lavender, and its scent relieves tension and has an effect on the stability of the spirit.
In addition, anti-inflammatory, bactericidal, and sedative effects suppress scalp inflammation and itching and keep them clean.
In addition, it has the effect of regulating sebum secretion and suppresses the stickiness of the scalp.
It also keeps the scalp flexible.
In addition, it inhibits the activity of 5-α relaxase, which causes hair loss, and is excellent in hair growth.
It also helps control hair loss and improve hair growth.

Rosemary extract not only smells good, but also has its health and beauty benefits. The alpha-pinene terpene contained in the rosemary extract has a tissue regeneration action, an anti-inflammatory action, and a smooth blood effect.
In addition, rosemary extract is effective for hair growth and hair growth. It is known that rosemary extract has a great effect of sterilizing germs such as anti-inflammatory effect, blood circulation promotion, sedation, analgesia, tonicity, antiseptic, sterilization, and antibacterial.

  In using the hair rinse of the present invention containing the above-mentioned components, after washing the hair with shampoo, for example, about 1 teaspoon is dissolved in hot water in the basin 7-8 minutes (about 600 times), and the hair is drawn. Then rinse well.

  Hereinafter, specific examples of the present invention will be described.

(Experimental purpose)
The standard dilution of commercially available citrate rinse is 200- to 300-fold dilution. The relationship between the dilution amount and pH is examined to obtain the optimum dilution amount of the rinse of the present invention.

(Experiment contents)
The pH of each of the following two types of rinses is measured according to the dilution amount.
1. Hair rinse agent of the present invention (Example rinse)
2. Commercial citrate rinse manufactured by M Company (Comparative Example Rinse)

(Experimental result)

(Discussion)
From the experimental results, when compared from the pH value, the recommended dilution amount of the comparative example rinse is 200 times to 300 times, and the dilution factor of the example rinse corresponds to 600 times to 770 times.
Therefore, the example rinse can be estimated from 600 to 770 times as shown in FIG. 2 from the pH value.
In addition, it can be said that the amount used for the example rinse is one-half to one-third the appropriate amount compared to the commercially available citric acid rinse (comparative example rinse).

(Experimental purpose)
The following experiment was conducted for the purpose of confirming the effect of reducing the color loss of the hair dyeing agent of the present invention.

(Materials used in experiments)
The following materials were used to compare and measure the degree of color loss due to rinsing of hair dye.

(Rinse ingredients)
The main components of the comparative example rinse and the example rinse used in the experiment are as follows.

(experimental method)

  Using the two types of hair colors, a comparison experiment of the color drop rate between the example rinse and the comparative example rinse was performed according to the following procedure.

1. Using commercially available hair colors (two types), each two white brushes, for a total of four hair dyes.
2. Wash the 4 white brushes from 1 with a commercial soap shampoo.
3. After the above-mentioned processing 2, the comparative example rinse and the example rinse are performed for each one.
4). Each cleaning solution rinsed in the above 3 is collected as a measurement sample.
5. Using a spectrophotometer, compare the two samples collected in 4 above with a total of 4 samples with distilled water without turbidity. (Comparison measurement of color fading degree)

  Based on the experimental results in Example 1 described above, the rinsing dilution conditions were set to a 600-fold dilution of the example rinse corresponding to the 200-fold diluted pH value of the comparative rinse.

The experimental procedure is also illustrated in the flowchart of FIG.
The specific procedure of this experiment is also schematically shown in FIG.

(Comparison analysis of cleaning solutions)
The four residual liquids (cleaning liquids A1, A2, B1, and B2 shown in FIG. 4) finally obtained by the above procedure were analyzed with a spectrophotometer. Moreover, the color of these four rinse residual liquids was compared by visual observation, and the color fading degree by an external appearance was compared.

(Experimental result)

The measurement results by the spectrophotometer are shown in FIGS. 6A, 6B, 7A, and 7B.
The measurement results of the cleaning liquid when using a type A hair color are as shown in FIGS. 6A and 6B.
The measurement results of the cleaning liquid when using a type B hair color are as shown in FIGS. 7A and 7B.

  From these measurement results, the following was found.

  As shown in FIGS. 6A and 6B, in the case of hair color A, the maximum was a difference of 32.6% at 400 nm, and it was found that the example rinse had less color loss than the comparative example rinse.

  As shown in FIGS. 7A and 7B, in the case of hair color B, the maximum difference was 22.8% at 440 nm, and it was found that the example rinse had less color loss than the comparative example rinse.

  Further, when the colors of the four rinse residual liquids (cleaning liquids A1, A2, B1, and B2 shown in FIG. 4) are compared, the example rinse is clearly lighter in color, and the color fading degree is higher than the comparative example rinse. It was confirmed visually that there was little.

  The example rinse has the advantage that only one third of the amount used is required and the color loss is 22% to 32% less than the comparative example rinse.

  Therefore, according to the hair rinse agent of the present invention, it was confirmed by experiments that there was less color fading (color fading of colored dyeing) than the citrate rinsing conventionally used.
