Description

The present invention relates to a hair dye composition having good dyeability and less color fading associated with shampooing.

As hair dyes, two-component oxidative hair dyes comprising a first agent containing an oxidative dye such as p-phenylenediamine and a second agent containing an oxidant such as hydrogen peroxide are widely used. Yes. In this hair dye, an oxidative dye is penetrated into the hair and oxidative polymerization is carried out in the hair to produce a pigment, thereby dyeing the hair.

In addition to the role of oxidative polymerization of oxidative dyes, the oxidants used in hair dyes oxidize and decompose the melanin pigment in the hair to lighten the hair color and improve the coloring effect of the pigments produced by oxidative polymerization It also has another function of making it happen.

However, as a result of the hair being damaged by this oxidizing agent, it becomes difficult to hold the polymerized oxidative dye inside or on the surface of the hair, and there is a problem that the fastness to washing is lowered.

In order to improve the hair fastness in a hair dye using such an oxidizing agent, many techniques for protecting the generated pigment with silicone, a cationic polymer or the like have been proposed. However, all of these techniques are techniques for covering the hair surface and suppressing the loss of dye. Therefore, there are problems that the coating is removed by several times of hair washing and a sufficient effect cannot be obtained, and when the coating amount is increased and the durability is improved, the hair feels uncomfortable, or the hair is dyed again. When doing so, there was a problem that the dyeing property was deteriorated.

On the other hand, in hair decolorization, it is known to use various plant extracts to suppress hair damage during decolorization (Patent Document 1).

There has also been proposed a hair dye that contains a vegetable oil component and a plant-derived protein and does not cause much damage to the hair and has a good finish (Patent Document 2).

Further, a hair dye composition containing a royal jelly extract to suppress damage and excellent in fastness to washing with aging has also been proposed (Patent Document 3), but the effect is not sufficient.

An object of the present invention is to provide a hair dye composition that has good dyeability and little color fading associated with shampooing after hair dyeing (excellent fastness to shampooing).

Various vegetable oils and plant extracts are known to suppress hair damage during hair dyeing and decolorization, but generally, suppression of hair damage results in improved fastness to hair washing. Although this can be expected, on the other hand, since the penetration of the oxidative dye into the hair or the hair surface is also suppressed, there is a problem that the dyeing property is deteriorated.

The present inventor has found that, in a hair dye composition using an oxidizing agent, by using rosehip oil and a polyhydric alcohol in combination, the dyeing property is good and the hair-fastness is excellent.

Hair dyeing process The first agent of the hair dye composition shown in Table 1 and the second agent of the hair dye composition shown in Table 2 are mixed in a first agent: second agent = 1: 1. A composition was prepared. A hair dye composition equal in amount to the hair bundle was evenly distributed to about 2.0 g of the hair bundle of 100% Chinese white hair (manufactured by Beaulux), and then the hair bundle was brought to room temperature. Left for 15 minutes. After leaving, wash the hair dye composition with running water at about 40 ° C., apply about 0.5 g of the test shampoo shown in Table 3 and wash with hand for about 30 seconds, then wash with about 40 ° C. running water for 30 seconds. Rinse. Then, it was dried with a dryer. The dyeing property was evaluated with the naked eye. Two hair bundles were dyed each.

In this hair dyeing treatment, the dyeing properties after the treatment of the hair dye composition were evaluated by 20 panelists as shown below.

Dyeing properties are uniformly dyed (5 points), uniformly dyed (4 points), dyed (3 points), slightly uneven, not very dyed (2 points), uneven The evaluation was made on a five-point scale (1 point) that was hardly dyed. An average score is calculated for each paneler's scoring results, and an average value of 4.6 or higher is “uniformly dyed: 5”, 3.6 to 4.5 points is “uniformly dyed: 4 ”2.6 to 3.5 points are“ dyed: 3 ”, 1.6 to 2.5 are“ slightly uneven and not very dyed: 2 ”, 1 point to 1.5 The evaluation results were as follows: “There was unevenness and almost not stained: 1”, and “Evaluation of all members was 5 points: 6”.

Hair washing process One of the two hair bundles obtained in the hair dyeing process is coated with about 0.5 g of the test shampoo shown in Table 3, and washed by hand for about 30 seconds and then washed with running water at about 40 ° C. Rinse for seconds. Then, it was dried with a dryer. This operation was repeated 10 times. Then, the color fading condition (hair wash fastness test) was evaluated with the naked eye. In that case, it was evaluated by comparing with the remaining dyed hair bundle (reference dyed hair bundle) obtained in the hair dyeing step.

In this hair washing treatment, the hair fastness of the hair dye composition was evaluated by 20 panelists as follows.

Hair wash fastness No change from standard dyed hair bundle (5 points), almost no change compared to standard dyed hair bundle (4 points), slightly discolored compared to standard dyed hair bundle (3 points), dyed hair bundle In comparison with, the color fading was conspicuous (2 points), and the color fading was severe (no color remained) (1 point). The average score is calculated for each paneler's scoring result, and an average value of 4.6 or more is “not different from the standard dyed hair bundle: 5”, and 3.6 to 4.5 points is “compared to the reference dyed hair bundle” 4), 2.6 points to 3.5 points are “slightly discolored compared to the standard dyed hair bundle: 3”, and 1.6 to 2.5 are “dyed hair bundles” Color loss is conspicuous compared to: 2 ”, 1 point to 1.5 point is“ severe color fading (no color remains almost): 1 ”, and“ everyone's evaluation is 5 points: 6 ” Evaluation results were obtained.
