Description

  The present invention relates to a hair cosmetic composition containing an oily component and a glycosyl trehalose, and more particularly to a hair cosmetic composition that has improved moisturizing properties and flexibility without causing a sticky feeling. .

  In general, a hair cosmetic composition contains a humectant such as a saccharide, an amino acid, a proteolysate, and a polyhydric alcohol in order to impart moisture to the hair. Among humectants, saccharides, which are naturally derived raw materials, are used relatively frequently from the viewpoints of safety and availability. By the way, hair has an extremely large surface area, and unlike skin, most hairs are in direct contact with the outside air. Therefore, when the humectant is applied to the hair cosmetic, there is a problem that the sustainability of the moisturizing effect on the hair itself is extremely low.

Then, the composition disclosed by patent document 1 is known conventionally. Patent Document 1 discloses a cosmetic containing glycosyl trehalose as a component having an effect of suppressing moisture fluctuation in a composition. When this glycosyl trehalose is formulated into a hair cosmetic together with an oily component, it exerts a hair moisturizing effect and can give a natural feel without causing a sticky feeling to the hair.
International Publication No. 2004/056216 Pamphlet

  However, the glycosyl trehalose of Patent Document 1 has a problem that it gives hardness to hair when it is repeatedly subjected to chemical treatment and applied to damaged hair. For example, when it is applied to the whole hair with long hair and only the tip of the hair is damaged, a good feeling with a smooth and moist feeling is given in a portion where the damage from the root to the middle is small. On the other hand, there is a problem that the damaged hair end portion is hard. This is presumably due to the extremely high hydrophilicity of the surface of damaged hair and the excessive adhesion of glycosyl trehalose to the hair.

  In order to solve this problem, a method of blending known hair softening ingredients such as polyhydric alcohols, sugars other than glycosyl trehalose, amino-modified silicones, and cationic surfactants is considered. However, when these components are used in combination, since excessive flexibility is imparted from the root to the middle of the hair, there is a problem in that the volume of the entire hair is impaired or excessive stickiness is imparted. .

  As a result of diligent research by the present inventors, the hair cosmetic composition containing an oily component and glycosyl trehalose causes a sticky feeling by containing a surfactant having a specific structure in a specific ratio. It has been made by finding that moisture retention and flexibility can be imparted. The object of the present invention is to provide a hair cosmetic composition that can provide moisture retention and flexibility without causing a sticky feeling in a hair cosmetic composition containing an oily component and glycosyl trehalose. There is.

In order to achieve the above object, the hair cosmetic composition according to claim 1 is at least one selected from hydrocarbons, fatty acid esters, dimethylpolysiloxane, methylcyclopolysiloxane, methylphenylpolysiloxane, and waxes.

Next, the embodiment will be described more specifically with reference to examples and comparative examples.
In each example shown in Tables 1 and 2, a hair cosmetic composition as a hair treatment agent that was not washed away was prepared by mixing each component. For each composition, chemical treatment such as hair coloring, hair bleaching, or permanent wave is repeated several times, and 20 panelists whose hair is particularly damaged are actually used, and the moisture retention of hair, hair Sensory evaluation was performed on the feeling of stickiness, the softness near the hair root, the softness near the hair tips, and the richness of the composition at the time of application (texture of the treatment agent itself). The evaluation results are shown in Tables 1 and 2. In addition, the unit of the numerical value which shows the mixing | blending of each component in Table 1, 2 is the mass%. Moreover, the notation of (A)-(C) in a table | surface shows the compound corresponding to each component of this-application claim. On the other hand, the notations a and b in the table indicate comparative compounds of the respective components described in the claims of the present application.

(Moisture retention of hair)
An appropriate amount of each hair treatment agent that was not washed off was applied to each panel so that it was uniform from the root to the tip of the hair on one side divided into the left and right halves centered on the front before sleeping. Then, when the fingers are passed through the hair on the next morning, compared to the hair on the side where the treatment agent is not applied, the hair on the applied side is moist and evaluated based on whether or not it feels moisture is maintained. did. When the number of people who are moist and evaluated that water is maintained is 18 or more, it is “excellent”, 11 to 17 is “good”, and 4 to 10 is “slightly bad” And “bad” when less than 4 people.

(Feeling of sticky hair)
The hair was treated in the same manner as described in the hair moisture retention column. Then, when the fingers are passed through the hairs on both sides the next morning, evaluation is made based on whether or not the stickiness is felt, and the case where the number of persons who evaluate that there is no stickiness is 18 or more is “excellent”. Was “good”, the case of 4 to 10 people was “slightly bad”, and the case of less than 4 people was “bad”.

(Hair softness (flexibility))
The hair was treated in the same manner as described in the hair moisture retention column. Then, the evaluation was made based on whether or not the softness of the hair was felt when the fingers were passed through the hairs on both sides the next morning. The case of 11 to 17 people was “good”, the case of 4 to 10 people was “slightly bad”, and the case of less than 4 people was “bad”.

(The texture of the composition when applied (the texture of the treatment itself))
The hair treatment agent that is not washed off in each case is evaluated by whether each panelist feels the cream when it is picked up. The case of 11 to 17 people was “good”, the case of 4 to 10 people was “somewhat bad”, and the case of less than 4 people was “bad”.

In Examples 1 to 9 containing the component (C), all evaluations of moisture retention, stickiness, and hair softness were “excellent”. In Examples 1 to 5 and 7 to 10, in which the component (B) is a polyoxyethylene dialkyl ether type nonionic surfactant, the evaluation of the body feeling was “excellent”.

  On the other hand, as shown in Table 2, Comparative Example 1 containing no glycosyl trehalose resulted in a decrease in water retention, softness near the root of the hair, and richness. Comparative Examples 2 and 3 in which the content of the component (B) and the content of the component (A) are out of the range of (A) / (B) = 0.1 to 10 in terms of mass ratio are moisture retention and hair The result was a decrease in softness.
