[0002]

2. Description of the Related Art Conventionally, oils such as silicone oil, ester oil and hydrocarbon oil have been used in hair cosmetics after solubilization, emulsification and dissolution in order to impart gloss and smoothness to hair. In particular, silicone oils have been widely used in recent years because they have low surface tension, are excellent in conformity to hair, and have good gloss. However, due to the nature of the oil itself, there has been a problem that when a large amount of silicone oil is used or a consumer uses it for a long period of time, the squeaky feeling of the hair increases and the hair becomes greasy.

On the other hand, cationic surfactants are frequently used for the purpose of protecting the hair and imparting smoothness to the hair, but they do not give a desired luster and are not preferred from the viewpoint of safety when incorporated in large amounts. was there.

Here, in the general formula (VIII), R ¹⁰
Represents a linear or branched saturated or unsaturated hydrocarbon group having 7 to 25 carbon atoms, and the number of carbon atoms is more preferably 9 to 23, further preferably 11 to 21. If the number of carbon atoms is less than 7, the hydrophilicity is too strong to form a complex, and if the number of carbon atoms exceeds 25, the melting point becomes high, and it is difficult to form a complex. The hydrocarbon group may have its hydrogen atom replaced by a hydroxyl group.

Specific examples of such higher fatty acids include straight-chain saturated fatty acids such as lauric acid, myristic acid, palmitic acid, stearic acid, arachinic acid, and behenic acid; 2-palmyltreic acid, petroselinic acid, oleic acid, and the like.

Further, the total amount of the surfactant and the higher fatty acid is preferably from 0.1 to 30% by weight, more preferably from 0.5 to 20% by weight, based on the total amount of the hair cosmetic. If the content is less than 0.1% by weight, it is difficult to obtain the stability of the emulsion, while if the content exceeds 30% by weight, the effect is saturated, so that it is not economical.

The organic acid as the component (b) includes, for example, citric acid, lactic acid, succinic acid, malic acid, L-glutamic acid,

If the content exceeds 1, the content of the amino group or ammonium group in the high molecular silicone becomes high, and a crosslinking reaction or the like occurs during the production, or it is not preferable from the viewpoint of raw material odor. Interaction becomes insufficient, and the persistence of the hair protection effect deteriorates.

The amino-modified or ammonium-modified high molecular silicone used in the present invention can be produced by a conventional method. That is, it can be produced, for example, by performing a polycondensation reaction between γ-aminopropylmethyldiethoxysilane, cyclic dimethylpolysiloxane, and hexamethyldisiloxane under an alkali catalyst, but is not limited to this. It is. These modified high molecular silicones are soft rubber-like, do not stick to the hair or scalp even when used in large quantities or are continuously used for a long period of time, impart excellent gloss and smooth feel to hair, and have a protective effect on hair. Can be enhanced.

When these high molecular silicones are incorporated into the cosmetic of the present invention, they are preferably dissolved in a liquid oil and incorporated. Of course, they may be separately incorporated into cosmetics and dissolved in the system. Examples of the liquid oil include a chain silicone, a cyclic silicone, and an isoparaffin hydrocarbon.

One or two or more of these liquid oils can be used, and the total amount thereof is preferably 1 to 50 times (weight) with respect to the high molecular silicone.

The amount of the component (c) is preferably 0.001 to 10.0% by weight, more preferably 0.1 to 7.0% by weight in the hair cosmetic. If it is less than 0.01% by weight, it may not be possible to impart sufficient smoothness and gloss to the hair, whereas if it exceeds 10.0% by weight, the hair may be sticky.

The hair cosmetic composition of the present invention may further contain, if necessary, qualitative and quantitative ranges that do not impair the effects of the present invention, such as camellia oil, rapeseed oil, sesame oil, safflower oil, cottonseed oil, and the like.

The hair cosmetics according to the present invention mean any cosmetics used for hair, and broadly include so-called hair treatment agents such as hair rinses, hair treatments and hair packs. Also, when using it,
After applying it to the hair and applying it to the whole, wash it away with water and so on (rinse), or use it as a non-rinsing type such as hair cream, hair spray, etc.
Both may be included.

The hair cosmetic composition of the present invention can be prepared, for example, by mixing an amphoteric surfactant and / or a semipolar surfactant with water and an organic acid to form an aqueous solution of the surfactant, which is then amino- or ammonium-modified. A product obtained by adding a higher fatty acid to a polymer silicone can be produced by a conventional means such as adding it with stirring and heating as necessary.

Here, by adding the higher fatty acid to the aqueous solution of the surfactant, the surfactant is adsorbed on the higher fatty acid and bonded at the carboxyl group of the higher fatty acid to form a complex. The adsorption of the surfactant to the higher fatty acid increases with the passage of time and saturates after a certain period of time.
In the present invention, the organic silicone resin is emulsified in an oil-in-water type (O / W type) or a water-in-oil type (W / O type) using this complex as an emulsifier. At this time, the complex is water-
It is oriented at the oil interface and acts as a strong interface film at the emulsified particle interface. For this reason, coalescence of particles is prevented, and a wide emulsifying power that is not affected by fluctuations in the required HLB of the oil can be obtained. In addition, it takes 30 to 60 minutes by a normal method to stably form an emulsified system. In the present invention, it takes only about 15 minutes, and the manufacturing process is simplified and shortened.

The emulsifying type of the hair cosmetic of the present invention differs depending on the form of the intended product, the type of other added components to be mixed, the mixing ratio of oil and water, and the like, and the O / W type or W / W type
Any suitable emulsion type of O type can be arbitrarily selected and used. In addition, a stable W / O / W or O / W / O type multi-phase emulsified hair cosmetic can be obtained by devising a preparation method such as a phase inversion emulsification method.

The dosage form of the hair cosmetic composition of the present invention may be either aerosol or non-aerosol.
