Description

The present invention relates to an out-bath treatment containing a dye and a hair dyeing method using the same.

In recent years, very saturated color styles have become popular. In addition to paraphenylenediamine, general coloring agents have been blended with oxidation dyes, toning agents (coupler dyes), etc. to express colors, but they have the problem of rapid fading.

In addition, since oxidation dyes and toning agents (coupler dyes) use oxidation polymerization to develop colors, it is difficult to say that they are easy to use, and they are accompanied by hair damage, and the strong allergic reactivity of paraphenylenediamine is also a problem. there were.

Therefore, HC dyes and basic dyes have attracted attention as dyes that can be easily replenished in home care, and color rinses, color treatments, color shampoos, etc. containing HC dyes and basic dyes have been proposed. Examples of hair cosmetics containing HC dyes and basic dyes include, for example, "an emulsified type containing an amide alcohol, an organic acid, and any one of HC dyes, basic dyes and/or acid dyes. Hair cosmetics." has been proposed (Patent Document 1).

However, color rinses, color treatments, color shampoos, etc. containing HC dyes or basic dyes require time to wash off after applying the dyes, which is time-consuming and difficult to do at home. There is also the problem of discoloration. In addition, there is also the problem that the dye is applied to the entire hair, and the easy-to-dye part is dyed darker, and the difficult-to-dye part is lighter in color, resulting in color unevenness.

[Example 1]
As shown in Table 1 below, each component was blended in the ratio shown in the same table to prepare a foam-like out bath treatment. Specifically, after first dissolving chitosan (E) and keratin (F1) in ethanol (D), the remaining ingredients are added in proportions shown in the same table, and ingredients generally blended in foam treatments, etc. The out bath treatment was prepared by mixing and adjusting to 100 total.

[Examples 2 to 5]
As shown in Table 1 below, an out bath treatment was prepared in the same manner as in Example 1, except that the blending amounts of the HC dye (A) and the basic dye (B) were changed.

[Comparative Example 1]
As shown in Table 1 below, an out bath treatment was prepared in the same manner as in Example 1, except that the HC dye (A) and the basic dye (B) were not blended.

Using the out bath treatments of Examples 1 to 5 and Comparative Example 1, dyeing and color transfer resistance were evaluated. These results are also shown in Table 1 below.

The hair tresses used for each evaluation were uniformly bleached and damaged with a bleaching agent (length 10 cm, level 15 after 1 g of bleaching) without any treatment.

The evaluation was made on a 6-level scale from 0 to 5, and the average score was calculated by 5 participants.

Since the out-bath treatment is not washed off, dyeing and color transfer resistance were evaluated at the time of application to the hair tress.

[Dyed]
The hair tress was wetted with a water spray, excess water was wiped off with a towel, and the tress was immersed in a container in which the out bath treatment was dissolved in water, and immediately removed from the container. Wipe off excess water with a towel and dry with a hair dryer. The density of the color of the hair tress after drying was visually observed to evaluate the dyeing. It should be noted that the higher the numerical value, the higher the evaluation of dyeing.

[Color transfer resistance]
The hair tress was wetted with a water spray, excess water was wiped off with a towel, and the tress was immersed in a container in which the out bath treatment was dissolved in water, and immediately removed from the container. Wipe off excess water with a towel and dry with a hair dryer. Color transfer resistance was evaluated by visually observing the density of the dye adhering to the towel when wiping off. It should be noted that the higher the numerical value, the less color transfer and the higher the color transfer resistance evaluation.

The higher the total amount of HC dye (A) and basic dye (B), the better the evaluation of dyeing. Even in the case of .1%, the evaluation of dyeing was good as compared with Comparative Example 1.

On the other hand, when the total amount of HC dye (A) and basic dye (B) was increased, the evaluation of color transfer resistance tended to decrease, but almost no color transfer occurred after drying. It has been found that early drying is also important, since this also meets the desire of users to dry their hair quickly after washing their hair at home. However, if the total amount of HC dye (A) and basic dye (B) exceeds 1.0%, the evaluation of color transfer resistance tends to be poor. ) is preferably 1.0% or less. Since color transfer can be reduced by using a penetrating agent, a film-forming agent, etc. together, even when the total amount of the HC dye (A) and the basic dye (B) exceeds 1.0%, they can be used.

[Example 6]
As shown in Table 2 below, each component was blended in the ratio shown in the same table to prepare a foam-like out bath treatment. Specifically, after first dissolving chitosan (E) and keratin (F1) in ethanol (D), the remaining ingredients are added in proportions shown in the same table, and ingredients generally blended in foam treatments, etc. The out bath treatment was prepared by mixing and adjusting to 100 total.

[Examples 7 to 9]
As shown in Table 2 below, an out bath treatment was prepared in the same manner as in Example 6, except that the amount of bisethoxydiglycol cyclohexane-1,4-dicarboxylate (C) was changed.

[Comparative Example 2]
As shown in Table 2 below, an out bath treatment was prepared in the same manner as in Example 6 except that bisethoxydiglycol cyclohexane-1,4-dicarboxylate (C) was not blended.

[Comparative Example 3]
As shown in Table 2 below, an out bath treatment was prepared in the same manner as in Example 6 except that bisethoxydiglycol cyclohexane-1,4-dicarboxylate (C) and ethanol (D) were not blended.

Using the out bath treatments of Examples 6 to 9 and Comparative Examples 2 and 3, dyeing, durability, color transfer resistance and dyeing speed were evaluated. These results are also shown in Table 2 below.

The evaluation of dyeing and color transfer resistance was performed in the same manner as described above. The evaluation was made on a 6-level scale from 0 to 5, and the average score was calculated by 5 participants.

〔durability〕
The dyed tresses were rinsed with shampoo repeatedly (5 or 20 times) and evaluated for durability. In addition, it shows that durability evaluation is so high that a numerical value is high.

[Dyeing speed]
The hair tress was wetted with a water spray, excess water was wiped off with a towel, and the tress was immersed in a container in which the out bath treatment was dissolved in water, and immediately removed from the container. Wipe off excess water with a towel and dry with a hair dryer. The dyeing speed to the hair tress after drying was evaluated. It should be noted that the higher the numerical value, the higher the evaluation of the dyeing speed.

Examples 6 to 9 in which cyclohexane-1,4-dicarboxylic acid bisethoxydiglycol (C) was blended are Comparative Examples 2 and 3 in which cyclohexane-1,4-dicarboxylic acid bisethoxydiglycol (C) was not blended. Compared to , it can be seen that dyeing, durability, color transfer resistance, and dyeing speed are all excellent.

In addition, if bisethoxydiglycol cyclohexane-1,4-dicarboxylate (C) is not completely dried after use, it tends to fade due to its penetrating power. It is preferable to take preventive measures.

[Example 10]
As shown in Table 3 below, each component was blended in the ratio shown in the same table to prepare a foam-like out-bath treatment. Specifically, after first dissolving chitosan (E) and keratin (F1) in ethanol (D), the remaining ingredients are added in proportions shown in the same table, and ingredients generally blended in foam treatments, etc. The out bath treatment was prepared by mixing and adjusting to 100 total.

[Examples 11 to 13]
As shown in Table 3 below, an out-bath treatment was prepared in the same manner as in Example 10, except that the blending amount of ethanol (D) was changed.

[Comparative Example 4]
As shown in Table 3 below, an out-bath treatment was prepared in the same manner as in Example 10, except that ethanol (D) was not blended.

Using the out bath treatments of Examples 10 to 13 and Comparative Example 4, dyeing, durability, color transfer resistance and dyeing speed were evaluated. These results are also shown in Table 3 below.

The dyeing, durability, color transfer resistance and dyeing speed were evaluated in the same manner as described above. The evaluation was made on a 6-level scale from 0 to 5, and the average score was calculated by 5 participants.

Examples 10 to 13 in which ethanol (D) is blended are superior in dyeing, durability, color transfer resistance, and dyeing speed compared to Comparative Example 4 in which ethanol (D) is not blended. Recognize.

If the ethanol concentration is too high, a slight shift (discoloration) of the dye tends to occur. Therefore, from the viewpoint of discoloration and speed, the ethanol concentration is preferably 5% or less.
