Description

[Detailed Description of the Invention] [Industrial Application Field J] The present invention provides a novel hair cosmetic that gives shine and smoothness to hair, has excellent conditioning effects, and that these effects last for a relatively long time. Regarding.

[Prior Art] In general, when hair is subjected to complex and repeated beauty treatments such as washing, brushing, heat with a hair dryer, hair coloring, and bleaching agents, hair becomes significantly damaged and degraded, resulting in dryness, frizz, and split ends. It is well known that hair loss, hair breakage, and plucking cause an increase in hair size and a decrease in strength.

Therefore, for the purpose of protecting and repairing hair against the above-mentioned hair damage, hair cosmetics use various raw materials extracted from natural products such as proteins, polysaccharides, extracted extracts, etc. as a base for hair cosmetics.
Natural polymers or their constituent elements or oligomers such as amino acids, peptides, etc. are fully blended.

[The problem that the invention tries to solve! ! ! ] Natural product extracted raw materials are effective to some extent in preventing hair damage and protecting hair from chemical or mechanical treatments, but they all have insufficient adhesion to the hair, and the hair may become smooth and rough after use. However, it was still not satisfactory due to the inferior feel of the product.

Therefore, an object of the present invention is to provide a hair cosmetic that can prevent hair damage, protect hair from chemical or mechanical treatments, and at the same time impart smoothness and flexibility to improve combability. It is about providing.

[Means for Solving the Problems] That is, the present invention provides a combination of one or more high molecular weight silicones represented by the following general formula [I] and a mucopolysaccharide.
The present invention provides a hair cosmetic characterized by containing S or two or more types.

(R1 represents a methyl group or a part of phenyl group, R2
represents a methyl group or a hydroxyl group. Also, n is 3,00
Represents an integer from 0 to 20,000. ) Hereinafter, the configuration of the present invention will be explained in detail.

The high molecular weight silicone used in the present invention is represented by the above general formula [I], and the value of n in the formula 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 blending amount of high molecular weight silicone is 0.00% of the total amount of hair cosmetics.
It is 1 to 50% by weight, preferably 1 to 30% by weight. 0
．． If it is less than 1%, a sufficient effect cannot be obtained, and if it exceeds 50%, it becomes difficult to dissolve.

The mucopolysaccharides used in the present invention include hyaluronic acid, chondroitin 4-sulfate, chondroitin-8 sulfate,
Examples include dermatan sulfate, chondroitin 4.8 disulfate, germatan 4,8 disulfate, keratan sulfate, heparan sulfate and salts thereof. Among these, hyaluronic acid, chondroitin 4-sulfate, chondroitin 8-sulfate, and salts thereof are preferred.

The amount of mucopolysaccharide used in the present invention is 0.001 to 10% by weight based on the total amount of hair cosmetics, preferably 0.01% by weight.
~5% by weight. If it is less than 0.001% by weight, the effect of the mucopolysaccharide combination cannot be fully exhibited, and if it exceeds 10% by weight, the viscosity increases too much, which is not preferable in terms of usability.

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. Of course, they may be separately incorporated into hair cosmetics and dissolved in the system.

Low boiling point chain silicone is represented by the following general formula, specific examples:
Examples include hexamethyldisiloxane, octamethyltrisiloxane, decamethyltetrasiloxane, and hexadecamethylheptasiloxane.

(In the formula, n represents an integer of 0 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 20 (l) at normal pressure, such as Exxon. Isopar (registered trademark) A1 C1 D1 E1 G1 H1 L1 M1 Shellsol (registered trademark) 71 manufactured by Shell Co., Ltd. Tsurutrol (registered trademark) 100 manufactured by Philips Co., Ltd. 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, trimethylolethane, trimethylolpropane, erythritol, pentaerythritol, sorbitan, and 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, waxes such as lanolin, jojoba oil, and carnauba wax, hydrocarbon oils such as liquid paraffin, squalane, petrolatum, and volatile isoparaffin, fatty acids,
These include alcohols, ester oils such as cetyl octoate and isopropyl myristate, silicone oils such as dimethylpolysiloxane and methylphenylpolysiloxane, and oils such as silicone resins.

In addition to the above-mentioned ingredients, the hair cosmetic of the present invention may include water-soluble polymers, chelating agents, antioxidants, ultraviolet absorbers, etc. within a quantitative and qualitative range that does not impair the effects of the present invention, depending on the purpose. Preservatives, medicines such as vitamins and hormones, fragrances, etc. may be added.

[Effects of the Invention] The hair cosmetic of the present invention is a hair cosmetic that gives rich luster and smoothness to the hair, has an excellent conditioning effect on the hair, and has these effects that last for a relatively long time. It is a fee.
