Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a water-soluble hair makeup that gives hair a wet-like shine and smooth feel, and maintains a wet-looking hairstyle. This is related to fees.

[Prior Art] Conventionally, hair cosmetics have been used by solubilizing, emulsifying, or dissolving oils such as silicone oils, ester oils, and hydrocarbon oils for the purpose of imparting luster and smoothness to hair. In particular, silicone oil has been widely used in recent years because it has a low surface tension, blends well with hair, and provides good gloss. On the other hand, cationic surfactants are also frequently used for the purpose of imparting smoothness.

In addition, polymer compounds such as polyvinylpyrrolidone polymers, acidic polyvinyl ether polymers, acidic acrylic polymers, or cationic polymers are blended for the purpose of hair setting.

[Problems to be Solved by the Invention] However, with oils such as silicone oil, the recent hair styling trends require a wet shine and its durability, but this is not always possible. It was not something I could enjoy. Furthermore, it cannot be easily removed by washing with water when washing it off from the hair or hands.

In addition, cationic surfactants that are blended for the purpose of imparting smoothness do not impart desirable gloss, and have the disadvantage of being unfavorable from a safety standpoint when blended in large amounts.

On the other hand, although the above-mentioned polymer compounds blended for the purpose of setting hair have excellent hair fixing or setting power, they do not satisfy hair styling with gloss, smoothness, and wet feeling.

In view of these circumstances, the present inventors have created a water-soluble hair cosmetic that imparts a wet-like shine and smooth feel to the hair and maintains a wet-feeling hairstyle. As a result of intensive research, we found that a compound containing a water-soluble polymer and a specific type of glycerin and polyoxyalkylene-modified organoborisiloxane was found.
We have discovered that these problems can be solved and have completed the present invention.

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

(Margin below) Hereinafter, the configuration of the present invention will be explained in more detail.

The water-soluble polymer used in the present invention may be natural, semi-synthetic, synthetic, or inorganic. Examples of natural water-soluble polymers include gum arabic, gum tragacanth, galactan, guar gum, carob gum, gum karaya, carrageenan, pectin, agar, quince seed (quince), vegetable polymers such as glycyrrhizic acid, xanthan gum, textran, Examples include microbial polymers such as succinoglucan and pullulan.

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

Examples of synthetic water-soluble polymers include vinyl polymers such as polyvinyl alcohol, polyvinyl methyl ether, polyvinylpyrrolidone, carboxyvinyl polymer (Riki-Bopol), and polyethylene glycol 20,000
．． 4. Examples include polyoxyethylene polymers such as OOO, 0OO1600, and 000, acrylic polymers (polyethyleneimine, cationic polymers) such as sodium polyacrylate, polyethyl acrylate, and polyacrylamide.

Examples of inorganic water-soluble polymers include bentonite, Δ1Mg silicate (veegum), laponite, hectorite, and silicic anhydride.

One or more of these may be appropriately selected and used.

Among the water-soluble polymers used in the present invention, carboxyvinyl polymers are particularly preferred from the viewpoint of effectiveness. Carboxyvinyl polymers can be obtained, for example, by copolymerizing acrylic acid and a crosslinking agent in the presence of azodiisobutyronitrile.
.

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. If the amount is less than 0.1% by weight, the fixing force immediately after application to the hair will be insufficient, and if it exceeds 3% by weight, the fixing force will be more than necessary and the usability will be sticky, which is undesirable.

Glycerin used in the present invention has been used as a humidity conditioner for the purpose of keeping the hardness and viscosity of products constant for a long time.
It has also been widely used in cosmetics as a skin softener to improve the spread and slippage of products (Cosmetic Ingredients Standards, 2nd Edition Commentary).

(See section on concentrated glycerin).

The amount of glycerin blended in the hair cosmetic of the present invention is 35 to 80% by weight, preferably 40 to 70% by weight, based on the total amount of the hair cosmetic. If the weight is less than 35 weights, the shine and setting properties of the hair will be insufficient, and if it exceeds 80 weights, the finish will be heavy and sticky, which is undesirable.

The polyoxyalkylene-modified organopolysiloxane used in the present invention is represented by the above general formulas [A] to [D], and contains 40 to 90% by weight of polyoxyalkylene groups based on the total weight of the polymer. , preferably 50-80
% by weight and has a viscosity of 10 to 300 centistokes at 25°C. That is, when the amount of polyoxyalkylene groups based on the total weight of the polymer is less than 40 times, the durability of gloss and smoothness are poor,
If it exceeds 90 M%, it is not preferable because it tends to reduce the smooth curls and hair set properties. Regarding the viscosity, if the viscosity is lower than 10 centistokes, the squeakiness will increase and the durability of the gloss will be poor, and if it exceeds 300 centistokes, the smoothness will be poor, which is not preferable.

The amount of polyoxyalkylene-modified organopolysiloxane used in the present invention is 0.1% of the total amount of hair cosmetics.
~30% by weight, more preferably 0.5~2
It is 0% by weight. If it is less than 0.1% by weight, the durability of gloss and smoothness will be poor, and if it exceeds 30% by weight, the effect will not change.

In the present invention, in addition to the above-mentioned essential components, it is preferable to add a basic substance as a neutralizing agent. As a basic substance,
Usually used sodium hydroxide, potassium hydroxide,
Hydroxides such as ammonium hydroxide, L-arginine, L
- Basic amino acids such as lysine, triethanolamine,
Examples include organic amines such as 2-amino-2-methylpropanol and ammonia. The blending amount is such that the pH after neutralization is 5~
An amount in the range of 8 is preferred.

Furthermore, the hair cosmetic of the present invention preferably contains water or water-containing ethanol in order to exhibit its effects. The compounding amount is
The amount is preferably 10 to 60% by weight based on the total amount of hair cosmetics. 10
If it is less than 60% by weight, the water content tends to be low and the wet gloss will be lost, but if it exceeds 60% by weight, the effect will not change. In addition, regarding water-containing ethanol, the water/ethanol mixing ratio is arbitrary between 50,150 and 10,010.

The hair cosmetic of the present invention may contain oil, a moisturizing agent such as a polyhydric alcohol having two or more hydroxyl groups in the molecule, and a chelating agent, within a quantitative and qualitative range that does not impair the effects of the present invention, depending on the purpose. , antioxidants, ultraviolet absorbers, surfactants, preservatives,
Drugs such as vitamins and hormones, collagen, keratin, etc.
Hydrolysates such as elastin, amino acids, pegyptides,
Natural polysaccharides, powders, fragrances, etc. may also be blended.

[Effects of the Invention] The present invention relates to a hair summer cosmetic that imparts a wet-looking shine and smooth feel to the hair, and which maintains a wet-looking hairstyle.
