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.

[Conventional technology]

Conventionally, hair cosmetics have been used by solubilizing, emulsifying, or dissolving oil components such as silicone oil, ester oil, and liquid paraffin in an organic solvent such as alcohol in order to impart luster and smoothness to the hair. In particular, silicone oil has a low surface tension (it blends well with hair and gives a good shine), and has been widely used in recent years.However, there are limits to its oil content.
If a large amount is used or if the consumer uses it for a long time, it has the disadvantage that the hair becomes oily. In addition, cationic surfactants are often used for the purpose of imparting smoothness, or they do not provide the desired gloss, and when added in large amounts, they have the drawback of being unfavorable from a safety standpoint.

In addition, polymer compounds such as polyvinylpyrrolidone polymers, acidic polyvinyl ether polymers, acidic acrylic polymers, and cationic polymers are used, but although these are excellent in fixing the hair, they do not provide luster or smoothness. It wasn't satisfying. Additionally, it has the disadvantage of hardening the hair and making it stiff.

[Points to be solved by the present invention]

The inventors of the present invention conducted intensive research to solve this problem, and found that when high-molecular-weight silicone is dissolved in low-boiling oil, the low-boiling oil evaporates and forms a thin, soft silicone rubber film on the hair. It has been found that it gives a glossy and smooth feel, improves greasiness on the hair, and has excellent sesotropy.

This silicone rubber film has good water repellency and is difficult to wash off even with shampoo, but it has the disadvantage that it can peel off due to physical forces. In other words, the adhesion and adhesion of the silicone rubber film to the hair is weak and the film is relatively brittle.For this reason, the film is easily peeled off by daily brushing, and its excellent gloss and smooth feel do not last. there were. In an extreme example,
This silicone rubber film peels off and is scattered on the hair in the form of a white powder: this is what is called a powdering phenomenon.

Therefore, the present inventors have developed a silicone rubber film that strengthens its adhesion to hair, gives it properties that make it difficult to peel off, and provides excellent gloss, a smooth feel, no greasiness on the hair, and moisturized hair. As a result of further intensive research aimed at sustaining these effects, it was surprisingly discovered that the above-mentioned drawbacks could be overcome extremely effectively by combining high molecular weight silicon with organic silicone resin, and the present invention was completed. did.

[Means to solve the problem]

That is, the present invention is characterized by containing one or more types of high molecular weight silicone represented by general formula (1) and one or more types of organic silicone resin represented by average formula (n). It is a hair cosmetic product that

General formula (1) RI: methyl group or a part thereof is phenyl group R2: methyl group or hydroxyl group n: integer average formula of 3,000 to 20,000 (I
[) R: Hydrocarbon group having 1 to 6 carbon atoms, or phenyl group n: 1.0 to 1.8 The high molecular weight silicone used in the present invention is a high molecular weight silicone represented by the above general formula So, the value of On in the formula is 3,000
~200,000. In terms of molecular weight, it is approximately 250,000 to 1,500,000, and its properties are soft rubber-like at room temperature.

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

Conventionally, dimethylpolysiloxane having a degree of polymerization in the range of 3 to 650 has been used as a cosmetic ingredient, but there has never been an example of incorporating a high molecular weight silicone such as the one of the present invention into a cosmetic.

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.1 When the high molecular weight silicone of the present invention is blended into hair cosmetics, it may be dissolved in volatile oil and blended. preferable. Of course, they may be separately blended into hair cosmetics and dissolved in the system.

The organic silicone resin represented by (I[) above used in the present invention is R35iO! 4 units, R25iO units, R310
32 and an appropriate combination of 5 to 11, the ratio is selected to satisfy the average formula Rn5iO,
It is desirable to have an average molecular weight of about 1,500 to 10,000.

The above organic silicone resin is soluble in benzene and can be produced by various methods. -For example, general formula R3Si
X, R2SiX2, R51X3 and SiX
4 (X is a hydrolyzable group, such as chlorine, bromine, fluorine, alkoxy, such as methoxy, ethoxy, etc.)
(representing an acyloxy group) is added to a suitable solvent such as toluene, benzene, xylene, etc. depending on the desired resin composition, and then this solvent is subjected to the desired hydrolysis and co-condensation in a suitable acidic solvent. Add enough water to obtain removing the aqueous phase from the resulting two-phase system and neutralizing the remaining resinous material with a sufficient amount of sodium bicarbonate or other alkaline substance;
By distilling off the solvent, the desired organic silicone resin can be obtained.

The amount of organic silicone resin blended in the present invention is preferably 0.1 to 25% by weight based on the total amount of the hair cosmetic. If this happens, the cured film properties of the organic silicone resin will become stronger, and on the contrary, the adhesion to hair will decrease.

High molecular weight silicone and organic silicone resin are 9515-10
/, 90 ratio is preferred, especially 60/40 to 20/
A ratio of 80 is good.

Volatile oils (low boiling point oils) include low boiling point linear silicones,
Examples include cyclic silicone and low boiling point isoparaffinic hydrocarbons.

The low-boiling chain silicone is represented by the following general formula, and specific 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 260°C at normal pressure, such as Exxon's Isopar (registered trademark) A1, C1, E1, G1, H1, L1, M1, Shellsol (registered trademark) 71, Philips Corporation, Tsurutrol (registered trademark) 1
Examples include 00, 130, and 220.

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.
~80% by weight is preferred.

Examples include trichlorotrifluoroethane and tetrachlorodifluoroethane. Any one or two or more of these may be used, and the total blending amount is preferably 1 to 50 times (by weight) the amount of high molecular weight silicone.

In addition to the above components, lower alcohols such as ethanol and IPA may be added. Furthermore, as a component that can be added to the present invention, there are silicone oil derivatives, such as linear dimethyl silicone oil, methylphenyl silicone oil,
One or more optional components such as silicone polyether copolymer, amino-modified silicone oil, epoxy-modified silicone oil, and fluorine-modified silicone oil can be added.

The purpose of adding this silicone oil derivative is to modify the high molecular weight silicone-organosilicon resin film. It is well known that low molecular weight plasticizers are added to modify resin films, but conventional plasticizers such as phthalic acid derivatives and higher alcohol polyoxyethylene ethers are used for high molecular weight silicone-organosilicon resin systems. is unsuitable from the viewpoint of compatibility. In this regard, silicone oil derivatives have good compatibility in the high molecular weight silicone-organosilicon resin system, effectively plasticizing the resin film, strengthening the adhesion of hair, and creating an ideal film that does not lose its smoothness or stickiness. I found something to gain.

Specific examples of silicone derivatives used in the present invention include the following.

The blending amount of these silicone oil derivatives is 0.1 to 40%, but it is preferably added in an amount of 10 to 80% based on the amount of (high molecular weight silicon+organosilicon resin). If it is less than 10%, the plasticizing power will be weak, and if it exceeds 80%, (high molecular weight silicon + organic silicone resin) will not form a film, which is not preferable. 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 2M system of oil-water, and a three-layer system of oil-water and powder.

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.

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.), glucose, 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.

Namely, oils and fats such as olive oil, coconut oil, safflower oil, castor oil, and cottonseed oil, wax oils such as lanolin, jojoba oil, and carnauba wax, hydrocarbon oils such as liquid paraffin, squalane, petrolatum, and volatile isoparaffin, fatty acids, Oils commonly used in cosmetics include alcohols, ester oils such as cetyl octoate and isopropyl myristate, silicone oils such as dimethylpolysiloxane and methylphenylpolysiloxane, and silicone resins.

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 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 a high molecular weight silicone and an organic silicone resin is 10% by weight. It is preferable that the amount of the water-soluble polyhydric alcohol is 5 to 30% by weight based on the total amount of the cosmetic and about 50 to 99% by weight relative to the surfactant.

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

In addition to the above-mentioned essential components, the hair cosmetic 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.
