Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a hair cosmetic that provides excellent gloss and smooth feel to hair.

Conventionally, hair cosmetics have been used by solubilizing, emulsifying, or dissolving oils such as silicone oil, ester oil, and liquid paraffin in organic solvents such as alcohol in order to impart luster and smoothness to the hair. In particular, silicone oil has been widely used in recent years because of its low surface tension, excellent adhesion to hair, and good gloss. However, there is a limit to the oil content.
If a large amount is used or if the consumer uses it for a long time, it has the disadvantage of making the hair greasy. In addition, cationic surfactants are often used to impart smoothness, but they do not provide the desired gloss, and when added in large amounts,
It also had the disadvantage of being unfavorable in terms of safety.

In addition, polymer compounds such as polyvinylpyrrolidone polymers, acidic polyvinyl ether polymers, acidic acrylic polymers, or cationic polymers are used, but although these have excellent hair fixing and setting properties, they do not have gloss or smoothness. was not satisfactory. Additionally, it has the disadvantage of hardening the hair and making it stiff.

[Problems to be Solved by the Invention] The inventors of the present invention have solved these drawbacks, and have provided hair with excellent luster and a smooth feel, without greasiness, and with moisturized hair. We proposed a hair cosmetic that is characterized by its ability to tame hair.

That is, high molecular weight silicone is melted with low boiling point silicone, and after the low boiling point silicone volatilizes, a thin, soft silicone rubber film is formed on the hair, giving it an excellent luster and smooth feel.

This silicone rubber film has good water repellency and is difficult to wash off even with shampoo, but has the drawback of "peeling off" due to physical forces. That is, the silicone rubber coating had weak adhesion to hair, and was a relatively "brittle" coating.

For this reason, the film was easily peeled off by daily brushing, and the excellent gloss and smooth feel did not last.

Particularly when a large amount is applied, the silicone rubber film may peel off, resulting in what is called flaking, a white powdery appearance on the hair.

The present inventors have strengthened the adhesion of the silicone rubber film to the hair, giving it a property that is resistant to "peeling", and has excellent gloss, smooth feel, no greasiness on the hair, and moisturized hair. As a result of intensive research aimed at sustaining these effects, the inventors discovered that adding a silicone oil derivative as a plasticizer to high molecular weight silicone is extremely effective, and completed the present invention.

[Means for solving problems]

That is, the present invention provides one or more high molecular weight silicones represented by the general formula R1; a methyl group or a part thereof is a phenyl group R2; a methyl group or a hydroxyl group n; an integer from 3,000 to 20,000; , a silicone derivative selected from the group consisting of linear dimethyl silicone oil, methylphenyl silicone oil, silicone polyether copolymer, amino-modified silicone oil, epoxy-modified silicone oil, fluorine-modified silicone oil, alcohol-modified silicone oil, and alkyl-modified silicone oil. This hair cosmetic is characterized by containing one or more of the following.

The high molecular weight silicone used in the present invention has a high molecular weight represented by the above general formula, and exhibits a soft rubber-like property at room temperature.

Specific chemical structures include dimethylpolysiloxane, methylphenylpolysiloxane, dimethylpolysiloxane containing a terminal hydroxyl group, and methylphenylpolysiloxane containing a terminal hydroxyl group.

The blending amount of high molecular weight silicone in the present invention is 0.1 to 25% of the amount of cosmetics, and if it is less than 0.1%, there is no effect, and if it exceeds 25%, the viscosity of the cosmetic will be 30,000 cps or more. Difficult to apply to hair.

Specifically, the silicone derivatives used in the present invention are as follows:
For example:

) SiO] m Si (CH3) 3, R2 is absent or represents an alkyl group with a prime number of 10 to 16, or an integer of 1 to 200. ) The purpose of adding this silicone oil derivative is to modify high molecular weight silicone.

It is well known that low molecular weight plasticizers are added to modify resin films, but conventional plasticizers, phthalic acid derivatives, higher alcohols, and polyoxyethylene ethers are not compatible with high molecular weight silicones. It is inappropriate because of In that respect, silicone oil derivatives have good compatibility with high molecular weight silicones,
We have discovered that we can effectively plasticize a resin film, strengthen its adhesion to hair, and obtain an ideal film that does not lose its smoothness or stickiness.

The blending amount of these silicone oil derivatives is 0.1 to 40% by weight based on the total amount of hair-forming mineral, but should be added in an amount of 10 to 80% by weight based on the amount of high molecular weight silicon.

If it is less than 10%, the plasticizing power will naturally be weak, and if it exceeds 80%, the high molecular weight silicon will no longer form a film.

Volatile oils (low boiling point oils) that dissolve high molecular weight silicones and silicone derivatives include low boiling point linear silicones,
Cyclic silicones, low-boiling isoparaffinic hydrocarbons, and hydrocarbon fluorocarbon low-boiling silicones are represented by the following general formula, and specific examples include hexamethyldisiloxane, octamethyltrisiloxane, decamethyltetrasiloxane, Hexadecamethylheptasiloxane, etc.

(The following is a blank space) The cyclic silicone is represented by the following general formula, and specific examples include octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, and tetradecamethylcycloheptasiloxane.

(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. Isopar (registered trademark) A, C1 E1 G, H1 1, M1 Shellsol (registered trademark) 71 manufactured by Shell, Tsurutrol (registered trademark) 1 manufactured by Philips
00, 130°■3, 220, etc.

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 the high molecular weight silicone.
~50 times (weight) is preferable, and 10 times the total amount of hair cosmetics.
(preferably 80% by weight) Furthermore, examples of the fluorochloro-substituted hydrocarbon include trichlorotrifluoroethane and tetrachlorodifluoroethane. Any one or more of these can be used, and the total blending amount is 1 to 5% based on the high molecular weight silicone.
0 times (weight) is preferable.

In addition to the above components, lower alcohols such as ethanol and IPA may be added.

The dosage form of the present invention is arbitrary, and may be any one such as a solubilized system, an emulsified system, a powder dispersion system, a two-layer system of oil-water, and a three-layer system of oil-water-powder.

In the case of an emulsion system, it is common to use an oil phase containing high molecular weight silicone by emulsifying it with a nonionic surfactant, cationic surfactant, anionic surfactant, or a mixture thereof. A preferred method is to prepare a mixture of caulking surfactant and water-soluble polyhydric alcohol and then mix it with an oil phase to obtain an emulsified composition.

Water-soluble polyhydric alcohol is a polyhydric alcohol having two or more hydroxyl groups in the molecule, and specific examples include ethylene glycol, propylene glycol, 1,3-butylene glycol, 1,4-butylene glycol, and dipropylene. These include glycol, glycerin, polyglycerin (diglycerin, triglycerin, tetraglycerin, decaglycerin, etc.), glycose, maltitol, sucrose, fructose xylitol, erythritol, starch-degrading sugar-reducing alcohol, and one or two of these. More than one species can be arbitrarily selected and used.

As the oil constituting the oil phase of the emulsified cosmetic, the following oils can be mentioned in addition to the high molecular weight silicone according to the present invention.

In other words, oils and fats such as olive oil, coconut oil, safflower oil, castor oil, and cottonseed oil, wax oils such as lanolycene, jojoa oil, and carnauba wax, liquid paraffin, squalane,
Commonly used in cosmetics, such as hydrocarbon oils such as vaseline and volatile isoparaffin, fatty acids, alcohols, ester oils such as cetyl octoate and isopropyl myristate, silicone oils such as dimethylpolysiloxane and methylphenylpolysiloxane, and silicone resins. It is an oil used in

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

The emulsification type of the emulsified cosmetic may be either a water-in-oil type or an oil-in-water type, but it is desirable to prepare the emulsion so as not to lose the water repellency, which is the effect of the present invention.

In addition to the above-mentioned essential components, the hair makeup amount of the present invention includes:
Depending on the purpose, drugs such as ultraviolet absorbers, antioxidants, preservatives, vitamins, hormones, and fragrances may be added within a quantitative and qualitative range that does not impair the effects of the present invention.
