Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to hair cosmetics such as hair rinses, hair conditioners, hair treatments, hair sprays, and foamed hair styling products. Without,
To provide a hair cosmetic that has good smoothness during rinsing and a good residual feeling after rinsing, is free from stickiness, dryness, and catching on the hair after drying, and is capable of imparting a smooth, moist, and slippery finish.

[Conventional technology]

Hair cosmetics, such as hair rinses, hair treatment men, and hair cosmetics used during styling, are used to improve hair problems after perming, washing, and styling, and they provide smooth and moisturizing properties to the hair. There is a demand for a product that provides effects such as providing smooth texture, smooth combing and brushing, and making hair moist and easy to manage.

Conventionally, hair cosmetics with such effects include those whose main ingredients are cationic surfactants such as quaternary ammonium salts, those whose main ingredient is silicone oil, and those whose main ingredient is water-soluble polymer compounds. Various hair cosmetics have been proposed, including those containing hair as the main ingredient.

[Problem to be solved by the invention]

However, in conventional hair cosmetics, these active ingredients alone have problems with at least one of adsorption to hair, releasability from hair, feel of use, and finish performance, and their effects are not fully satisfactory. For example, hair cosmetics containing silicone oil have a very high effect of imparting lubricity to the hair, but on the other hand, they lack the effect of imparting a moist feeling.
Moreover, it is difficult to apply it uniformly to the hair. Also,
Hair cosmetics that use silicone oil in combination with other oils are
Although it has an excellent smoothing effect, it lacks a residual feeling after rinsing. That is, with conventional techniques, it is difficult to obtain a hair cosmetic that provides a good feel in all processes of treatment with a hair cosmetic, such as the feeling of use, the feeling during and after rinsing, and the feeling of finished hair. Therefore, from this current situation, there is a need for a hair cosmetic that has a rich feeling of use, an appropriate residual feeling, a light and firm feeling on the hair, and a smooth finish that satisfies the users. desired.

[Means and Effects for Solving the Problems] In view of the above circumstances, the present inventors have developed a product that does not have a slimy feeling when used, has good smoothness when rinsing, and has a good residual feeling after rinsing, and does not leave the hair sticky after drying. As a result of extensive research with the aim of obtaining a hair cosmetic that is excellent in the effect of imparting a smooth, moist, and silky finish without causing dryness or catching, we have found that Silicone, a hydrocarbon and/or ester having a specific inorganic value/organic value, and a water-soluble polymer compound are used together, and more preferably, a specific phosphate ester represented by the following formula (2) or a salt thereof is added. The present inventors have discovered that by doing so, a hair cosmetic having all of the above effects can be obtained and the above objects can be achieved, and the present invention has been completed.

That is, in order to achieve the above object, the present invention provides the following general formula (1) (wherein R1 is a hydrogen atom, a lower alkyl group having 1 to 3 carbon atoms, or a phenyl group, and R2 is a 3 (lower alkyl group or hydroxyl group, and n is 900 or more) and has a viscosity of 10,000 centistics or more at 25°C, and the organic value is on the horizontal axis, and the inorganic value is on the horizontal axis. In the organic concept diagram with the value as the vertical axis, the value of tanθ = inorganic value / organic value is a hydrocarbon and/or ester located in the range of 0 to 30', and a water-soluble polymer compound.

If it is lower than t, the object of the present invention cannot be achieved.

In addition, the amount of the silicone oil of formula (1) above is preferably 0.08 to 95% (weight%, the same hereinafter), particularly 0.1 to 50% of the total hair cosmetic. If the amount is less than 0.08%, the desired effect may not be obtained, and if it exceeds 95%, the hair may become sticky and have an undesirable heavy finish.

In the present invention, a specific hydrocarbon and/or ester is blended as the second essential component, and by blending this second component, formula (1) is difficult to uniformly adhere to the hair surface when blended alone. The object of the present invention can be achieved by improving the adhesion of silicone oil.

Here, the hydrocarbons and esters used in the present invention have tanθ=inorganic value/organic value θ of 0 to 30 in an organic conceptual diagram in which the horizontal axis is the organic value and the vertical axis is the inorganic value. °

[Examples 1 and 2, Comparative Examples 1 to 9] Hair rinse compositions having the compositions shown in Table 1 were prepared, and the results were evaluated using the above method to determine the slimy feeling during use, smoothness during rinsing, residual feeling after rinsing, and finish. The smoothness, smoothness, moistness, non-stickiness, and non-dryness of the hair were evaluated.

The results are also listed in Table 1.

As can be seen from the results in Table 1, the hair cosmetic containing oil together with a cationic surfactant and a higher alcohol (Comparative Example 2) has the effect of imparting a moist finish, but lacks smoothness. Hair cosmetics containing dimethyl silicone (Comparative Examples 3 to 6) have the effect of imparting smoothness and smoothness to hair, but are inferior in terms of moist feel and lack of dryness. Furthermore, when a phosphoric acid ester was used in combination to solve these drawbacks (Comparative Examples 7 to 9), deterioration in sliminess and lumpiness was observed during use. On the other hand, the hair cosmetic according to the present invention, which uses a combination of silicone, hydrocarbon, ester, and water-soluble polymer compound (Example 1), is excellent in all effects, and when a phosphate ester is further added (Example 2)
