Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair styling material, and more particularly to a hair styling material having less stickiness, excellent cohesiveness of hair, and capable of imparting softness to hair.

[0002]

2. Description of the Related Art Generally, hair styling materials include surfactants, fatty acids,
In addition to a base component consisting of at least one kind of higher alcohol, etc., silicone oil is blended, and the properties of the silicone oil are used to enhance the hair styling effect. In general, a hair styling composition which is highly sticky to hair and contains silicone oil with less stickiness has a problem that the hair lacks cohesiveness.

[0003] Therefore, no hair styling composition containing silicone oil has been able to simultaneously achieve a low stickiness to the hair, an excellent cohesiveness of the hair and a softness to the hair.

[0004]

DISCLOSURE OF THE INVENTION The present invention solves the above-mentioned problems in the conventional hair styling materials, has less stickiness to the hair, has excellent cohesiveness of the hair, and imparts softness to the hair. An object of the present invention is to provide a hairdressing material that can be used.

[0005]

Means for Solving the Problems The present inventors have conducted intensive studies in order to solve the above-mentioned problems. As a result, when the crosslinked methylpolysiloxane is blended into a hairdressing material, the hair is less sticky to the hair, and The present inventors have found that a hair styling material which has excellent hair cohesiveness and can impart softness to hair can be obtained, and has completed the present invention.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, the compounding amount of a crosslinked methylpolysiloxane to a hairdressing agent is 0.1 to 5
% By weight (that is, 0.1 to 5% by weight of the crosslinked methylpolysiloxane in the hair styling material), and particularly preferably 0.1 to 1% by weight. That is, by setting the blending amount of the cross-linked methylpolysiloxane to 0.1% by weight or more, it is possible to improve the cohesiveness of the hair and sufficiently exert the effect of imparting softness to the hair. By setting the blending amount of the cross-linked methylpolysiloxane to 5% by weight or less, a hair styling material with less stickiness to hair can be obtained.

In preparing the hairdressing composition of the present invention,
In addition to the crosslinked methylpolysiloxane, surfactant components such as anionic surfactants and nonionic surfactants, and base components such as fatty acids and higher alcohols (eg, cetanol, stearyl alcohol, behenyl alcohol, etc.) are appropriately selected. Mixed. The preparation of the hairdressing composition of the present invention is carried out by dissolving or dispersing at least one of the base components and the crosslinked methylpolysiloxane in water or a solvent containing water as a main component. If necessary, for example, an ester oil, a humectant, a polyhydric alcohol, an organic fine particle powder, a fragrance and the like can be appropriately compounded.

[0008] The hairdressing composition of the present invention may be in any dosage form such as a gel or a cream. Regardless of the form, for example, a hair cream, a milky lotion, a hair foam, a hair spray , Hair lotions and the like.

[0009]

Next, the present invention will be described more specifically with reference to examples. However, the present invention is not limited to only these examples.

Example 1 and Comparative Examples 1-2 Hair styling compositions of Example 1 and Comparative Examples 1-2 were prepared with the compositions shown in Table 1. The unit of the numerical value indicating the amount of each component is part by weight. The cross-linked methylpolysiloxane used in Example 1 was KSG-15 (trade name) manufactured by Shin-Etsu Chemical Co., Ltd.
When KSG-15 (trade name) is used, decamethylcyclopentasiloxane is contained in a ratio of 7 g with respect to 0.5 g of the cross-linked methyl polysiloxane. Therefore, decamethylcyclopentasiloxane is also incorporated in the hairdressing composition of Example 1, but this decamethylcyclopentasiloxane is not essential. In order to make it clear, the hair dressing of Comparative Example 1 shows an example in which no cross-linkable methylpolysiloxane was blended and decamethylcyclopentasiloxane was increased.

[0011]

[Table 1]

The hair styling preparations of Example 1 and Comparative Examples 1 and 2 prepared as described above were evaluated for less stickiness, cohesiveness of hair, and softness of hair as follows.

The test hair bundle is healthy hair and weighs 0.
A hair bundle made of 5 g and having a length of 18 cm was used, and one end of this bristle bundle was tied with a rubber band and the other end was free (free).

The hair bundle was treated with the above Example 1 and Comparative Examples 1 to
Each of the hairdressing preparations No. 2 was applied after stretching about 0.5 g of palm on each palm, and the above evaluation items were evaluated by five panelists. The evaluation method and evaluation criteria are as follows.

Low stickiness: The hair tress after application of the hairdressing material is squeezed twice from top to bottom with three fingers, and the feel at that time is evaluated on a five-point scale according to the following evaluation criteria.

Evaluation criteria: 5: Stickiness is not noticed (finger slippage is good). 4: Little stickiness (smooth finger movement is good). 3: Sticky (finger slippage is slightly bad). 2: Very sticky (finger slippage is bad). 1: Severely sticky (finger does not slip at all).

Hair cohesion: The cohesion of the hair bundle after application of the hairdressing agent is visually observed (especially at the hair tips). The results are evaluated on a 5-point scale according to the following evaluation criteria.

Evaluation Criteria: 5: Even one hair is not disordered. 4: Several hairs are disturbed, but the hair bundles are organized as a whole. 3: The middle part is gathered, but the hair tips are not gathered. 2: The whole hair bundle is disturbed. 1: The hairs are completely separated and not organized.

Hair softness: 3 hair bundles after applying hairdressing
Squeeze between the top and bottom with the fingers of the book twice and evaluate the feeling at that time on a 5-point scale according to the following evaluation criteria.

Evaluation Criteria: 5: Improvement in softness is considerably large 4: Improvement in softness is large 3: Softness is improved 2: Softness is improved, but the degree is small 1: Not at all Not soft

The evaluation results are shown as an average value of five panelists. However, in the display in Table 2, the figures after the decimal point are rounded off.

[0022]

[Table 2]

As is clear from the results shown in Table 2, the hairdressing preparation of Example 1 has less stickiness to the hair, has excellent cohesiveness of the hair, and can impart softness to the hair. On the other hand, the hair styling preparation of Comparative Example 1 in which the crosslinked methylpolysiloxane was not added and the amount of decamethylcyclopentasiloxane was increased was less sticky, but the cohesiveness of the hair was poor, and the crosslinked methylpolysiloxane was poor. The hair styling composition of Comparative Example 2 in which the high-polymerized methylpolysiloxane (1) (100,000 cst) was blended in place of siloxane was excellent in the cohesiveness of the hair, but was very sticky. None of the hairdressings were satisfactory.

[0024]

As described above, according to the present invention, the stickiness to the hair is small, and the cohesiveness of the hair is excellent.
Moreover, a hair styling agent capable of imparting softness to hair could be provided.
