BACKGROUND OF THE INVENTION
The present invention relates to a hair treatment composition that prevents the outflow of pigment from dyed hair and maintains the color.
[0002]
[Prior art and problems to be solved by the invention]
Hair dyeing with acidic dye-based hair dyes is used to adsorb hair dyes directly to the hair due to its ionic nature, and is widely used because of its wide variety of colors and high safety, but generally by shampoo etc. There is a problem that the fastness to shampooing is inferior, and for the purpose of improving the fastness of such dyeing, a method of treating with a color fading preventive agent such as 2-hydroxybenzyl alcohol so far (JP-A-9-20625), A method of blending a hair-penetrating organic solvent into a hair dye (Japanese Patent Laid-Open Nos. 61-210023 and 7-101841), and further adding a colored fluorescent dye such as a halogenated fluorescein to an acidic dye. A method for improving the dyeing effect (JP-A-8-128128) has been reported.
[0003]
However, even these means cannot sufficiently prevent discoloration due to repeated use of dyed shampoos, treatment agents, hair styling agents, etc., and 2-hydroxybenzyl alcohol has a high melting point and is stably blended. In addition, when a fluorescent dye is used directly, there is a problem that the hair color is affected and the adsorptivity is only superficial.
[0004]
An object of the present invention is to provide a hair treatment composition that can effectively improve dyeing properties and fastness to washing without affecting the dyeing color.
[0005]
[Means for Solving the Problems]
As a result of examining the desorption and discoloration of the dye adsorbed on the dyed hair, the present inventors have found that if a composition containing a fluorescent whitening dye and a specific penetration accelerator is used, the hair color is affected. It has been found that it is possible to effectively prevent color fading of dyed hair without giving it and to prolong the color.

[0020]
In the hair treatment composition of the present invention, other components used in cosmetics can be used depending on the purpose. For example, nonionic active agents, anionic active agents, amphoteric active agents, and cationic active agents may be included as 0.1 to 10.0% by weight as emulsifiers and solubilizers. Moreover, a polyhydric alcohol (glycerin, propylene glycol, etc.), various amino acids, and a polypeptide can be included as a humectant 0.01 to 20.0 weight%. As a preservative, parabens can be contained in an amount of 0.01 to 1.0% by weight. Moreover, antioxidant, a fragrance | flavor, and a coloring agent can be included 0.001-5.0weight%.
[0021]
Here, as the viscosity modifier, it is preferable to use a water-soluble polymer. For example, natural gums such as xanthan gum, guar gum, gum arabic, carrageenan, caraya gum, locust bean gum, or modified products thereof, hydroxyethyl cellulose, methyl cellulose , Cellulose derivatives such as carboxymethyl cellulose, alginic acid derivatives such as sodium alginate and propylene glycol alginate, synthetic polymers such as polyvinyl alcohol, polyvinyl pyrrolidone, sodium polyacrylate and polyethylene glycol, among others, hydroxyethyl cellulose, xanthan gum And alkylene oxide modified xanthan gum is preferred.

[0025]
If the pH of the hair treatment composition of the present invention is too low, the hair and hand skin may be roughened by the acid component, and if too high, the effect of promoting the penetration of the fluorescent whitening dye of the component (A) into the hair will be reduced. Therefore, it is desirable that the pH is 2 to 6, and pH 2 to 5 is particularly preferable. The pH can be adjusted using an organic acid such as citric acid, glycolic acid, succinic acid, tartaric acid, lactic acid, malic acid, and fumaric acid.
[0026]
As the dosage form of the hair treatment composition of the present invention, various dosage forms such as liquid, gel, cream, emulsion, spray and foam can be arbitrarily selected.
[0027]
The hair treatment composition of the present invention is obtained by, for example, applying the hair treatment composition to hair dyed with an acid dye-based hair dye, leaving it at room temperature to 60 ° C. for 5 to 30 minutes, and then washing the hair. It is preferred to use. In applying the hair treatment composition, the hair may be wet or dry, and may be applied immediately after dyeing or after a period of time. Sufficient color fading prevention effect can be obtained.
[0028]
【Example】
Examples 1-2
1 g of goat hair was treated with 2 g of a hair dye having the composition shown in Table 1 below for 15 minutes, rinsed at an appropriate temperature, and then washed with shampoo.
[0029]
[Table 1]

[0030]
After drying, the hair treatment composition (Examples 1, 2 and Comparative Example 1) having the composition shown in Table 2 was treated for 15 minutes, and dried after shampooing. A shampooed product without hair treatment and only dried was prepared as Comparative Example 2, and the L, a, and b values were measured using a color difference meter (Minolta CR-300).
[0031]
[Table 2]

[0032]
Next, the hair treated as described above was shaken with a 2-fold diluted solution of shampoo composition shown in Table 3 below, 20 mL for 15 minutes at 30 ° C., and the dye that flowed out at this time was measured by absorbance. The goat hair after the spill test is dried, L, a, b values are measured, and ΔE _ab (ΔE _ab = [(ΔL) ² + (Δa) ² + (Δb) ² ] ^1/2 ) Asked. The results are also shown in Table 2.
[0033]
[Table 3]

[0034]
From this, it was shown that the outflow of the dye can be suppressed without changing the color tone by blending the fluorescent whitening dye. In addition, the processing agent composition which replaced the propylene carbonate of Example 1 with the dipropylene glycol was the same result as the comparative example 1.
[0035]
【The invention's effect】
In the hair treatment composition of the present invention, the fluorescent whitening dye efficiently penetrates into the hair and prevents the dye dye from flowing out in the dyed hair. The degree can be improved effectively and the color can last longer.
