3. Manufacture of hair cosmetics As described above, the present hair cosmetics are typically prepared by adjusting the content composition in a liquid state to a temperature exceeding the melting point, in an aqueous solvent adjusted to a temperature exceeding the melting point, Introduced under agitation, the mixture of the aqueous solvent and the content composition is further cooled to room temperature under agitation to form an oily capsule of the content composition in the aqueous solvent, which is preferably multivalent. It can be produced by adding an alkyl-modified carboxyvinyl polymer together with alcohol and further emulsifying by adding high molecular silicones.

  As described above, the content composition is melted at a temperature exceeding its melting point, generally around 70 ° C., and is introduced as a liquid into an aqueous solvent prepared at substantially the same temperature as that under stirring. . Stirring can be performed at a relatively low speed, specifically 10 to 1500 rpm, preferably 20 to 300 rpm, using a propeller, a paddle mixer, or the like. In addition, the introduction of the content composition into the aqueous solvent is performed by directly injecting the content composition into the aqueous solvent, preferably from the lower part of the aqueous solvent, using an injection means such as a liquid feed pump.

When used as a hair styling agent, both solid waxes and higher alcohols can be used as the solid oil, but it is preferable to contain at least waxes. After that, it is possible to perform hair styling by rubbing the oily particles into the hair. Stickiness and stiffness when styling are alleviated. When used as a hair treatment, hair rinse, or hair conditioner, solid oils are suitable for both waxes and higher alcohols, and cationic surfactants and low molecular weight silicones coexist in oily particles as auxiliary components. Is preferred. As the dosage form of the present hair cosmetic, for example, gels, creams, and multilayer type dosage forms are suitable, but are not limited thereto. Here, the hair treatment is a treatment that further penetrates the hair and supplements the hair with oil, moisture, and protein, and gives the hair gloss and firmness compared to a rinse or conditioner. It is a product form intended to do.

The oil phase was added to the water phase and emulsified with a homogenizer at 80 ° C., neutralized by adding (17), and cooled to 40 ° C. to obtain a normal emulsified wax.

  Table 8 shows an example product formulated with amino-modified polymer silicone (Example 15) and high polymerization degree dimethiconol (Example 16) as the polymer silicones. Manufactured according to the above, and each test item was confirmed in the manner described above. The results are shown in Table 9.

  According to the results shown in Table 9, the present hair cosmetic prepared using amino-modified polymer silicone or high-polymerization dimethiconol instead of polymer silicone was substantially the same as that using polymer silicone. It was revealed that the same level of particle size, hair styling ability, smoothness and stickiness were suppressed.

  In the following, examples of the present hair cosmetic composition according to another embodiment are shown as examples. All were manufactured by the process according to the manufacturing method of the above-mentioned Example 1, and each test item was confirmed in the way mentioned above. The results are shown in Table 10.
