Description

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

[Conventional technology]

Conventionally, hair cosmetics have been used by solubilizing, emulsifying, or melting oils such as silicone oils, ester oils, and hydrocarbon oils for the purpose of imparting shine and smoothness to hair. In particular, silicone oil has a low surface tension and is excellent at blending into hair.
It has been widely used in recent years because it gives a good gloss. However, there is a limit to the amount of oil it can contain, and 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. Cationic activators are also frequently used to impart smoothness, but they do not provide the desired gloss and have the disadvantage of being unfavorable from a safety standpoint if added in large amounts.

Further, for the purpose of hair centrifugation, polymer compounds such as polyvinylpyrrolidone polymers, acidic polyvinyl ether polymers, acidic acrylic polymers, and cationic polymers are used.

Although these have excellent hair fixing or setting power,
The gloss and smoothness were not satisfactory.

In view of the above circumstances, the present inventors have discovered that the above conditions are met when a specific silicone is blended into hair cosmetics, and have filed a patent application (Patent Application No. 6L-2
07328).

[Problem that the invention seeks to solve]

However, using this specific silicone alone has the drawbacks that it has a high boiling point, slows drying after application to hair, and has a high solution viscosity, making it difficult to apply to hair.

The inventors of the present invention have solved the disadvantages of stiff hair, giving the hair excellent luster, giving it a smooth feel, making it easy to apply to the hair without leaving any greasiness on the hair, and drying quickly after applying it to the hair. As a result of intensive research to obtain a hair cosmetic with appropriate setting power, the present invention was completed.

[Means to solve the problem]

That is, the present invention is based on the general formula (1) (Rs represents a methyl group or a part of phenyl group, R2
represents a methyl group or a hydroxyl group. Also, n is 3,000
Represents an integer between ~20,000. ) and trichlorotrifluoroethane and/or tetrachlorodifluoroethane, and the general formula (■) R3R7 A 0R4N R6
COORB (n: m=90: ranges from 10 to 50=50, and the molecular weight ranges from so, ooo to soo, ooo.

R3 and R7 are hydrogen atoms or steel groups, R4, R5
are alkyl groups each having 1 to 4 carbon atoms.

R6 is an alkylene group having 1 to 4 carbon atoms, R
12 is a saturated or unsaturated alkyl group having 1 to 24 carbon atoms, A is an oxygen atom or an Nll group. It is a cosmetic.

The high molecular weight silicone used in the present invention has a high molecular weight represented by the above general formula, and the value of n in the formula is 3.000.
In terms of 0 molecular weight, which is ~20,000, it is approximately 370,000 ~ 1
It has a hardness of about 500,000 and exhibits a soft rubber-like appearance 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 melt.

When blending the high molecular weight silicone of the present invention into hair cosmetics, it is preferable to melt and blend it in trichlorotrifluoroethane and/or tetrachlorodifluoroethane.

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

The amphoteric resin used in the present invention is soluble in the product or
It is a dispersible polymer. If an optional solvent such as ethanol is present, the polymer is one that is soluble or dispersible in the combined solvent system. Preferred resins are
n: m=90: 10-70:30 and R8 is 12-
Particularly preferred are those with saturated or unsaturated alkyl groups having 24 carbon atoms, and the blending amount is 0.1 to 10% by weight.
, preferably 0.5 to 2% by weight.

Trichlorotrifluoroethane and/or used in the present invention
Alternatively, the amount of tetrachlorodifluoroethane blended is 1 to 98.8% by weight, preferably 1 to 50% by weight, based on the total amount of the hair cosmetic.

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 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. Glycol, glycerin, polyglycerin (diglycerin, triglycerin, tetraglycerin, decaglycerin, etc.), glucose, maltose, maltitol, cystlr, fructose, xylitol, sorbitol, maltotriose, threitol, erythritol, starch decomposition sugar reducing alcohol and the like, and one or more kinds can be arbitrarily selected and used from these.

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, waxes such as lanolin, jojoba 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 10 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 the 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% by weight.
~70% by weight, water-soluble polyhydric alcohol is 5-30% by weight of the total amount of cosmetics, and 50-99% by weight relative to surfactant.
It is preferable to set it to a degree of .

The emulsified cosmetic may be emulsified in 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.
