2. Description of the Related Art Film-forming polymers such as polyvinylpyrrolidone, sodium polyacrylate and polyvinylpyrrolidone-polyvinylacetate copolymer are mainly used as a base for hair styling agents. The film-forming polymers exert a strong hair styling property by adhering and hardening the hairs, but the set hairs form a bundle, the hands and combs do not pass through, and it is hard and stiff. , There was a drawback that you could not re-hairstyle. So, recently, beeswax,
Waxes such as lanolin and candelilla wax are used as raw materials for hair styling agents.

[0003]

However, waxes are oils that are solid or semi-solid at room temperature, and when a hair styling agent containing them is used, the set hair is easy to pass through by hand and comb, and the finish is soft and stiff. However, the hair styling power was weaker than that of the film-forming polymers, and the stickiness on the hands and hair was strong, so that the hair became heavy over time.

[0004]

As can be seen from Table 4, in Comparative Example 5 in which fine particle silica was not blended at all and sodium polyacrylate as a conventional hair styling ingredient was blended, there was a hair styling property, but the feel was rough, and the hair styling property was improved. Although the durability of the hair styling was inferior, no fine particle silica was added at all, and no beefy feeling was obtained in Comparative Example 6 in which beeswax, which is a conventional hair styling ingredient, was added, but hair styling, stickiness, re-hair styling, and hair styling were achieved. It was inferior in terms of persistence of power and persistence of non-stickiness. However, in Examples 12 and 13 using the conventional hair styling ingredients sodium polyacrylate and beeswax in combination with fine particle silica, all tests were excellent. From the above, it was found that the effect of the present invention is not impaired even if the fine particle silica and the film-forming polymer and wax which are conventional hair styling components are used in combination.

As can be seen from Table 5, in Examples 14 to 16 in which fine particle silica and silicone composite powder were used together in a mass mixing ratio of 1: 0.1 to 1: 6, Comparative Example 7 using fine particle silica alone was used. In comparison, the creaminess was improved. However, in Comparative Example 8 in which the fine particle silica and the silicone composite powder were used together at a mass mixing ratio of 1: 6.7, the spreadability was poor and the hair styling power was also reduced.
Similar results were obtained when a silicone rubber spherical powder: Trefil ^™ (manufactured by Shin-Etsu Chemical Co., Ltd.) was used instead of the silicone composite powder.

From the above, it can be seen that when creaminess is required, it is more preferable to use the silicone rubber spherical powder and / or the silicone composite powder in combination, than to use the fine particle silica alone. The mass mixing ratio is 1: 0.1
It is suggested that ˜1: 6, especially 1: 0.2 to 1: 5 is preferred. Further, as a fine particulate silica, Nippon Aerosil Co. particulate silica 300 ^{T M} (average particle size 7 nm, specific surface area 300m ² / g), finely divided silica 380 ^TM

As can be seen from Table 6, Examples 17 to 20 in which the amount of the polyether-modified silicone compounded is 0.5 to 10% by mass, and particularly Example 1 in which the compounded amount is 1 to 7% by mass.
In Nos. 8 and 19, the emulsion stability, the lightness of spreading and the non-stickiness were excellent. However, Comparative Example 9 in which the polyether-modified silicone was not blended was inferior in emulsion stability, and the blending amount of the polyether-modified silicone was 2
In Comparative Example 10 with 0% by mass, there is stickiness,
It was also inferior in lightness.

Instead of the polyether modified silicone,
Crosslinking type polyether modified silicone: KSG-21
Similar results were obtained in terms of emulsion stability when ^TM (manufactured by Shin-Etsu Chemical Co., Ltd.) was used. When it is desired to adjust the usability, it is preferable to appropriately use a polyether-modified silicone and / or a cross-linking polyether-modified silicone in combination. From the viewpoint of emulsion stability, the blending amount is 0.5 to 10
It is preferably in the range of 1% by mass, particularly 1 to 7% by mass.

As can be seen from Table 7, in Examples 21 to 23 in which the content of the non-volatile oil component was 1 to 30% by mass, there was no stiffness, no stickiness, and excellent hair styling properties. Moreover, in Examples 22 and 23 in which the content of the nonvolatile oil component was 5 to 20% by mass, the non-stiffness was more excellent than that of Example 21. However, in Comparative Example 11 in which the content of the nonvolatile oil component was 32% by mass, stickiness occurred and the hair styling property was poor. From this, when a moist texture is desired, it is preferable to add a non-volatile oil component, and the amount thereof is 1 to
It is preferably 30% by mass, particularly 5 to 20% by mass. However, in the case where a dry texture is desired, the non-volatile oil component may not necessarily be blended.
