Description

The present invention relates to a hair treatment agent composition containing a direct dye.

Generally, a semi-permanent hair dye composition containing, for example, an acid dye is known as a direct dye. On the other hand, there is known an oxidative hair dye that allows an oxidative dye to penetrate into the cuticle of hair by the action of an alkaline agent, and causes the oxidant to decompose the melanin pigment and develop the color of the dye. The semi-permanent hair dye composition causes the dye to be ionically bonded to a very shallow portion of the cortex to develop a color. The semi-permanent hair dye composition has an advantage that damage to the hair can be suppressed as compared with the oxidative hair dye composition. However, there is a problem that the dyeing property is inferior to that of the oxidative hair dye.

Conventionally, so-called color treatment agents in which a dye is directly mixed with a treatment agent have been known. Since these are intended for hair dyeing, the amount of direct dye compounded is large and there are various color variations. Further, it can be used not only for dyeing hair but also for compensating for fading of hair color by applying it to hair that has been dyed.

For example, Patent Document 1 discloses a color treatment agent containing a direct dye or the like. Such a color treatment agent contains a cationic surfactant and a basic dye to improve dyeability and treatment effect.

(Effect on color tone)
Human hair bundle samples with ash-based color and red-based color (hereinafter, simply referred to as hair bundles) were prepared and evaluated for their influence on color tone. First, the black hair bundle is treated with a bleaching agent (Hoyu Co., Ltd., Rece Powder Bleach EX) at 30 ° C. for 30 minutes, washed with water, shampooed (Hoyu Co., Ltd .: Promaster Color Care LX Stylish Line), and then. It was dried with a dryer. Then, among the bleached hair bundles, those having the same brightness and feel were selected and the hair bundles were prepared. Using this hair bundle, hair was dyed into an ash-based hair bundle and a red-colored hair bundle, respectively. For the ash-based hair bundle, a commercially available hair coloring agent (manufactured by Hoyu Co., Ltd .: Promaster EX A-9 / 8) was used, and the hair was dyed according to a conventional method. For the reddish hair bundle, a commercially available hair coloring agent (manufactured by Hoyu Co., Ltd .: Promaster EX R-9 / 8) was used, and the hair was dyed according to a conventional method. Each hair bundle was shampooed (manufactured by Hoyu Co., Ltd .: Promaster Color Care LX Stylish Line) and then treated with the hair treatment agent composition of each example. After repeating the shampoo and treatment treatment 20 times each, the color tone of the hair bundle was evaluated according to the following criteria.

When there is no effect on both ash and red hair bundles compared to immediately after dyeing, "excellent: 5", when only one of the ash and red hair bundles is slightly affected compared to immediately after hair dyeing : "Good: 4", if both ash and red hair bundles have a slight effect compared to immediately after hair dyeing: "OK: 3", either ash or red hair bundle compared to immediately after hair dyeing When only one of them was affected: "Slightly defective: 2", and when both ash and red hair bundles were affected compared to immediately after hair dyeing: "Defective: 1".

(Skin stain suppression effect)
After applying 0.05 g of the hair treatment agent composition of each example to a 1-yen coin-sized area on the inner side of the forearm of the evaluation model (healthy adult), the hair treatment agent composition was left for 10 minutes and washed with water. After that, shampoo was performed and lightly pressed with a towel to remove moisture. The coloring on the skin surface was visually evaluated.

Twenty panelists were asked to evaluate the skin coloring by choosing between "less" and "not less", keeping in mind the normal evaluation feeling of skin stains. Of the 20 people, 16 to 20 panelists answered "good: 4", 11 to 15 people answered "possible: 3", and 6 to 10 people answered "slightly poor: 2". The case of 5 or less was regarded as "defective: 1".
