Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a hair cosmetic that imparts excellent gloss and smooth feel to hair and has good set-holding power.

[Prior art 1] Conventionally, hair cosmetics have been used by solubilizing, emulsifying, or dissolving oils such as silicone oils, ester oils, and hydrocarbon oils for the purpose of imparting gloss and smoothness to hair. In particular, silicone oil has a low surface tension and is highly compatible with hair.
It has been widely used in recent years because it gives a good gloss. However, oils such as silicone oil have a limited amount of oil content, and if used in large quantities or used by consumers for a long time, they have drawbacks such as increasing the squeaky feel of the hair and making it greasy. Cationic surfactants have also been widely used for the purpose of imparting smoothness, but they do not provide the desired gloss and have the disadvantage of being unfavorable from a safety standpoint if used in large amounts.

In addition, polymer compounds such as polyvinyl pyrrolidone polymers, acidic polyvinyl ether polymers, acidic acrylic polymers, or cationic polymers are blended, but although these have excellent hair fixing power, they do not provide gloss or smoothness. was not satisfactory.

Furthermore, it has the disadvantage of hardening the hair and making it stiff.

[Problems to be Solved by the Invention] In view of the above circumstances, the present inventors have developed a method that provides hair with excellent gloss, gives a smooth feel, is easy to apply to the hair without greasiness, and is easy to apply to the hair. As a result of intensive research to create a hair cosmetic that dries quickly after application and has appropriate setting power, we discovered that adding a cationized silicone polymer to high molecular weight silicone is extremely effective. The invention was completed.

[Means for Solving the Problems] That is, the present invention contains one or more types of high molecular weight silicones represented by the following general formula [I] and one or more types of cationized silicone polymers. The present invention provides a hair cosmetic product characterized by:

(R+ represents a methyl group or a part of phenyl group, R2
represents a methyl group or a hydroxyl group. Also, n is 3,000

~20,000, and exhibits soft rubber-like properties at room temperature. Specific examples include dimethylpolysiloxane, methylphenylpolysiloxane, dimethylpolysiloxane containing a terminal hydroxyl group, and methylphenylpolysiloxane containing a terminal hydroxyl group.

The amount of high molecular weight silicone used in the present invention is 0.1 to 25% by weight based on the total amount of the hair cosmetic.If it is less than 0.1% by weight, it will not be effective, and if it is heated more than 25 times, the viscosity will decrease to 3. If it exceeds 10,000 cps, it becomes difficult to apply it to the hair.

The cationized silicone polymer used in the present invention is represented by the following general formula [11], [Ill].

(In the formula, R3 represents a monovalent hydrocarbon group having 1 to 18 carbon atoms; R4 represents a C1 to CI8 alkylene group or alkylenoxy group that may contain an oxygen atom; Qe is a halide, preferably a chloride ion; Yes, r is 2 to 20

CAR5ILIKONE ALE 56J (UNIOH
CARBIDE), rABIL 9905J (G
(manufactured by OLDSCHMIDT), etc.

The amount of the cationized silicone polymer used in the present invention is 0.05 to 40% by weight based on the total amount of the hair cosmetic, but considering the modification and film properties of the high molecular weight silicone,
It is preferably 10 to 80% by weight, based on the high molecular weight silicone.

When blending the high molecular weight silicone of the present invention, it can be used by dissolving it in a volatile oil such as a low boiling point chain silicone oil, a low boiling point cyclic silicone oil, a low boiling point isoparaffinic hydrocarbon, or a fluorochloro substituted hydrocarbon. is preferred.

The low-boiling linear silicone can be expressed by the following general formula, and specific examples include hexamethyldisiloxane, octamethyltrisiloxane, decamethyltetrasiloxane, and hexatecamethylheptasiloxane.

(In the formula, n represents an integer of O to 5.) The cyclic silicone is represented by the following general formula, and specific examples include octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, and tetradecamethylcycloheptasiloxane. etc.

(In the formula, n represents an integer of 3 to 7.) Examples of low-boiling isoparaffinic hydrocarbons include isoparaffinic hydrocarbons having a boiling point in the range of 60 to 260°C at normal pressure, such as Exxon Co., Ltd. Isopar (registered trademark) A, C1, D1, E1, G1, H1, L1, M1, Shellsol (registered trademark) 71, manufactured by Shell, Tsurutrol (registered trademark) 100, manufactured by Philips, or Examples include 130 and 220.

Examples of fluorochloro-substituted hydrocarbons include trichlorotrifluoroethane and tetrachlorodifluoroethane.

The above-mentioned low boiling point oil can be used in any one kind or in combination of two or more kinds, and the total blending amount is 1 to 1 to 1 to 100% of the high molecular weight silicone.
50 times (by weight) is preferable.

Furthermore, in addition to the above components, lower alcohols such as ethanol and isopropyl alcohol may be added.

The dosage form of the present invention is arbitrary, such as a solubilized system, an emulsified system, a powder dispersion system, a two-layer system of oil-water, a three-layer system of oil-water and powder, etc.
Either is fine.

In the case of an emulsion system, it is common to emulsify an oil phase containing high molecular weight silicone with a nonionic surfactant, cationic surfactant, anionic surfactant, or a mixture thereof. Preferred is a method in which a mixture of a surfactant and a water-soluble polyhydric alcohol is prepared and then mixed with an oil phase to obtain an emulsified composition. Examples of polyhydric alcohols include propylene glycol, 1,3-butanediol, dipropylene glycol, glycerin, diglycerin, polyglycerin such as triglycerin, trimedyloethane, trimethylolpropane, erythritol, pentaerythritol, sorbitan, glucose, Examples include sorbitol, maltitol, sucrose, raffinose, trehalose, polyoxyethylene methyl glucoside, polyoxypropylene methyl glucoside, and the like. When preparing an emulsified composition, one or a combination of two or more of these may be used. Furthermore, as the oil constituting the oil phase, other oils such as those listed below can be used together with the high molecular weight silicone. In other words, oils and fats such as olive oil, coconut oil, safflower oil, castor oil, and cottonseed oil, dates such as lanolin, jojoba oil, and carnauba wax, liquid paraffin, squalane, petrolatum,
These include hydrocarbon oils such as volatile isoparaffins, fatty acids, alcohols, ester oils such as cetyl octoate and isopropyl myristate, silicone oils such as dimethylpolysiloxane and methylphenylpolysiloxane, and silicone resins.

The general blending amount of the above ingredients is preferably 0.5 to 10% by weight of the surfactant and 20 to 80% by weight of the oil phase containing high molecular weight silicone based on the total amount of the hair cosmetic. In the case of a method of preparing a mixture with a polyhydric alcohol and mixing it with an oil phase to obtain an emulsified composition, the surfactant is 1 to 20% by weight, and the oil phase containing high molecular weight silicone is 10 to 70% by weight. It is preferable that the water-soluble polyhydric alcohol accounts for 5 to 30% by weight of the total amount of the cosmetic and about 50 to 99% by weight relative to the surfactant.

In addition to the above-mentioned ingredients, the hair cosmetic of the present invention may contain preservatives, drugs such as vitamins and hormones, fragrances, etc., depending on the purpose, within a quantitative and qualitative range that does not impair the effects of the present invention.
