Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention provides a water-soluble hair makeup which imparts wet gloss and smooth feel to hair and maintains a wet hairstyle. It is about fees.

[Related Art] Conventionally, hair cosmetics have been used by solubilizing, emulsifying, and dissolving oil components such as silicone oil, ester oil, and hydrocarbon oil for the purpose of imparting gloss and smoothness to hair. In particular, silicone oils have been widely used in recent years because they have low surface tension, are excellent in conformity to hair, and have good gloss. On the other hand, cationic surfactants are frequently used for the purpose of imparting smoothness.

Further, for the purpose of setting the hair, a high molecular compound such as a polyvinylpyrrolidone-based polymer, an acidic polyvinyl ether-based polymer, an acidic acrylic-based polymer or a cationic polymer is blended.

[Problems to be Solved by the Invention] However, in oils represented by silicone oil,
The recent fashion of hair styling requires wet luster and its persistence, but this has not always been satisfactory. Furthermore, when washing off from hair or hands, it cannot be easily washed off with water.

Also, cationic surfactants incorporated for the purpose of imparting smoothness do not give desired luster, and there is a disadvantage that if incorporated in a large amount, safety is not preferable.

On the other hand, the above-mentioned high molecular compound compounded for the purpose of setting the hair is also excellent in fixing hair, that is, setting power, but does not satisfy gloss, smoothness, wet styling and the like.

In view of such circumstances, the present inventors, for hair,
As a result of intensive research on whether it would be possible to obtain a water-soluble hair cosmetic that gives a wet gloss and a smooth feel and maintains a wet hairstyle, it was identified as a water-soluble polymer. It has been found that a composition containing glycerin and a polyoxyalkylene-modified organopolysiloxane in an amount that can solve these problems has been accomplished, and the present invention has been completed.

[Means for Solving the Problems] That is, the present invention relates to 0.1 to 3% by weight of one or more water-soluble polymers, 35 to 80% by weight of glycerin, and the following general formulas [A] to [D]. ] A hair cosmetic characterized by comprising one or more polyoxyalkylene-modified organopolysiloxanes represented by the formula

(Wherein R is an alkyl group having 1 to 3 carbon atoms or a phenyl group, R ′ is hydrogen or an alkyl group having 1 to 6 carbon atoms,
p is an integer of 1 to 5, m is an integer of 0 to 100, n and x are integers of 1 to 100, t and y are integers of 0 to 50, and m, n, x and y are average numbers. Containing 40 to 90% by weight of a polyoxyalkylene group in the molecule and at 25 ° C
At a viscosity of 10-300 centistokes. Hereinafter, the configuration of the present invention will be described in more detail.

The water-soluble polymer used in the present invention may be any of natural, semi-synthetic, synthetic and inorganic. Examples of natural water-soluble polymers include plant gums such as gum arabic, tragacanth gum, galactan, guar gum, carob gum, karaya gum, carrageenan, pectin, agar, quince seed (quince), glycyrrhizic acid, xanthan gum, dextran, and succino. Microbial polymers such as glucan and pullulan are exemplified.

Examples of semi-synthetic water-soluble polymers include, for example, carboxymethyl starch, starch-based polymers such as methylhydroxypropyl starch, methylcellulose, nitrocellulose, ethylcellulose, methylhydroxypropylcellulose, hydroxyethylcellulose, sodium cellulose sulfate, hydroxypropylcellulose, Cellulose polymers such as sodium carboxymethylcellulose (CMC), crystalline cellulose and cellulose powder, and alginic acid polymers such as sodium alginate and propylene glycol alginate are exemplified.

Examples of the synthetic water-soluble polymer include vinyl polymers such as polyvinyl alcohol, polyvinyl methyl ether, polyvinyl pyrrolidone, carboxyvinyl polymer (Carbopol), and polyethylene glycol 20,000, 4,000.
Examples include polyoxyethylene polymers such as 0.000 and 600,000, and acrylic polymers (polyethyleneimine and cationic polymer) such as sodium polyacrylate, polyethyl acrylate, and polyacrylamide.

As the inorganic water-soluble polymer, for example, bentonite,
Silicic acid AlMg (Vegum), Laponite, Hectorite,
Silicic anhydride and the like can be mentioned.

One or more of these are appropriately selected and used.

Among the water-soluble polymers used in the present invention, a carboxyvinyl polymer is particularly preferred from the viewpoint of effects. A carboxyvinyl polymer can be obtained, for example, by copolymerizing acrylic acid and a crosslinking agent in the presence of azodiisobutyronitrile.
Carbopol 940,941,934 manufactured by BF Goodrich Chemical
And Hibiswako 104, 105 manufactured by Wako Pure Chemical Industries.

The amount of the water-soluble polymer used in the present invention is 0.1 to 3% by weight, preferably 0.5 to 2% by weight based on the total amount of the hair cosmetic.
It is. If the amount is less than 0.1% by weight, the fixing force immediately after application to the hair is insufficient, and if it exceeds 3% by weight, the fixing force becomes more than necessary, and the usability is not sticky.

Glycerin used in the present invention has been widely used in cosmetics as a humidity conditioner for the purpose of keeping the hardness and viscosity of the product constant for a long time, and as a softener for the skin to improve the elongation and slip of the product. (Refer to Cosmetic Ingredient Standards, Second Edition Commentary, Concentrated Glycerin).

The amount of glycerin in the hair cosmetic of the present invention is:
35-80% by weight of the total amount of the hair cosmetic, preferably 40
~ 70% by weight. If it is less than 35% by weight, the setting properties of gloss and hair are insufficient, and if it exceeds 80% by weight, the finish is heavy and the stickiness is further unpreferable.

The polyoxyalkylene-modified organopolysiloxane used in the present invention is represented by any one of the above general formulas [A] to [D], and contains a polyoxyalkylene group in an amount of 40 to 90% by weight based on the total weight of the polymer. , Preferably 50-80% by weight
It has a viscosity of 10 to 300 centistokes at 25 ° C. That is, when the amount of the polyoxyalkylene group relative to the total weight of the polymer is less than 40% by weight, the durability and smoothness of the gloss are poor, and when it exceeds 90% by weight, the smoothness and the setting property of the hair are deteriorated. It is not preferable because it acts in the direction. If the viscosity is lower than 10 centistokes, the feeling of creaking increases, and the durability of the luster is inferior. If the viscosity exceeds 300 centistokes, the smoothness deteriorates, which is not preferable.

The amount of the polyoxyalkylene-modified organopolysiloxane used in the present invention is 0.1 to 3 in the total amount of the hair cosmetic.
It is preferably 0% by weight, more preferably 0.5 to 20% by weight. If it is less than 0.1% by weight, the durability and smoothness of the luster are inferior, and if it exceeds 30% by weight, the effect is not changed.

In the present invention, it is preferable to add a basic substance as a neutralizing agent in addition to the above essential components. Examples of the basic substance include commonly used hydroxides such as sodium hydroxide, potassium hydroxide and ammonium hydroxide, basic amino acids such as L-arginine and L-lysine, triethanolamine, and 2-amino-2-methyl. Organic amines such as propanol and ammonia are exemplified. The compounding amount is preferably such that the pH after neutralization is in the range of 5 to 8.

Further, in order to exhibit the effect, the hair cosmetic of the present invention preferably contains water or hydrous ethanol. The compounding amount is preferably 10 to 60% by weight based on the total amount of the hair cosmetic. If it is less than 10% by weight, the moisture content is small, so that a wet luster tends to disappear, and if it exceeds 60% by weight, the effect is not changed. In addition, about water-containing ethanol, the water / ethanol mixture ratio is arbitrary between 50/50 and 100/0.

In the hair cosmetic of the present invention, a humectant such as a polyhydric alcohol having two or more hydroxyl groups in a molecule, an oil, a humectant, a chelating agent, in a quantitative and qualitative range that does not impair the effects of the present invention depending on the purpose.
