Description

The present invention relates to a hair dye composition.

Hair dye compositions are broadly classified into permanent hair dyes such as oxidative hair dyes using oxidative dyes, semi-permanent hair dyes using direct dyes, and temporary colorants using pigments. Among these, the hair dyeing property of the semi-permanent hair dye is lower than that of the permanent hair dye because no alkaline agent or oxidizing agent is used, but damage to the hair is small. On the other hand, although the oxidative hair dye has a high hair dyeing property, damage to hair is higher than that of a semi-permanent hair dye. Due to these differences, the demand for color treatment, which is one of semi-permanent hair dyes, is increasing in the market as a coloring agent that is used repeatedly.

Color treatments include variations for bright hair, which is generally called fashion dyeing, and for gray hair, which is called gray hair dyeing. For this reason, the hair dye colors required in the market range from colors close to primary colors such as blue, red and yellow, to brown and black, which have low saturation and lightness.

In general, color treatment imparts treatment properties to hair. For example, a cationic surfactant or a cationic polymer may be included to produce a light texture. In addition, an oily component may be included to give good fingering and gloss.

The color treatment contains a direct dye. Among direct dyes, basic dyes and HC dyes are mainly used, in which hair dyeing properties are not easily lowered even when used in combination with components that impart treatment properties.

For example, Patent Document 1 proposes a combination of a liquid ester oil, an alkylamidoamine, and a salt thereof for the purpose of achieving both hair dyeing power and improvement in fingering during hair drying. Patent Document 2 proposes a combination of an amine compound, an α-hydroxy acid, silicone, and a silicone derivative.

Although the hair dye composition obtained by the said patent documents 1 and 2 has high hair dyeing property, when it contains many oil-based components, there exists a tendency for hair dyeing property to fall, and it is compatible with treatment property and hair dyeing property. It was difficult.

The present invention solves the above problems. That is, an object is to provide a hair dye composition having hair dyeing properties while having treatment properties.

In the present invention, the treatment property means the fingering during rinsing and the texture after the hair is dried.

As a result of intensive studies to solve the above problems, the present inventor is a hair dye composition used for hair dyeing of keratin fibers, which contains a direct dye, and (A) has a viscosity at 25 ° C. of 50 mm ^2. / B or less methylpolysiloxane, (B) methylpolysiloxane having a viscosity at 25 ° C. of 10000 mm ² / s or more, and 5 to 20% by mass of (A) + (B) which is the sum of these masses The inventors have found that the above problem can be solved by setting the mass ratio (A) / (B) to 0.5 to 2, and have completed the present invention.

According to the present invention, a hair dye composition having treatment properties and hair dyeing properties can be obtained.

The present invention is described in detail below.

The hair dye composition according to the present invention contains a direct dye.

Examples of the direct dye used in the present invention include basic dyes, HC dyes, acid dyes, natural dyes, and disperse dyes.

Moreover, it is preferable that the total amount of said (A), (B) and an oil-based component does not exceed 30 mass%. If the content exceeds 30% by mass, sufficient hair dyeability may not be obtained.

The hair dye composition according to the present invention may contain a cationic surfactant, a nonionic surfactant, an amphoteric surfactant, an anionic surfactant, and the like as the surfactant. These can contain 1 type, or 2 or more types.

The surfactant used in the present invention is preferably 0.5 to 5% by mass. When the amount is less than 0.5% by mass, the storage stability of the hair dye composition cannot be maintained, and separation may occur.

Apply 10 g of bleaching agent (trade name: Palty Natural Bleach, manufactured by Dariya Co., Ltd.) evenly to 5 g of hair bundle, leave it for 30 minutes, wash with 1% SLS aqueous solution, rinse thoroughly with water, and towel Dry to prepare bleached hair.

2.5 g of each hair dye composition shown in Table 1 was uniformly applied to the bleached hair. After leaving for 5 minutes, 5 professional panelists washed the bleached hair with water. The following criteria evaluated the fingering at the time of the rinse at this time. The average value of five people was calculated, and the result was evaluated by rounding off the first decimal place.
(Evaluation criteria)
Fingering when rinsing hair is very good 5 points when rinsing hair is slightly good 4 points when rinsing hair is good 3 points when rinsing hair is slightly bad 2 points when hair is rinsing 1 point is bad when rinsing

[Feel after drying]
The hair bundle used for the finger evaluation at the time of rinsing was dried with a cool air of a dryer while passing through a comb. Five expert panelists evaluated the dried hair bundle according to the following criteria. The average value of five people was calculated, and the result was evaluated by rounding off the first decimal place.
(Evaluation criteria)
