Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a cosmetic for hair. More specifically, the present invention relates to a hair styling composition for hair styling, which is capable of styling hair with an appropriate setting force, has no stickiness, imparts gloss to the hair, and is excellent in retaining gloss.

[0002]

2. Description of the Related Art Hair styling products have been used for hair styling. An oily component such as hydrocarbon or ester is generally added to the hair styling agent in order to impart gloss to the set hair. However, when an effective amount of an oily component is added in order to impart a setting force, it has a drawback that the hair becomes sticky.

On the other hand, it is also practiced to add gloss to the hair by blending a polyhydric alcohol in place of the oily component. However, even if gloss can be imparted by blending the polyhydric alcohol, there is a drawback that the setting power is poor. Further, there is a drawback that stickiness occurs when the blending amount is increased.

The invention according to claim 5 further relates to a cosmetic for hair according to any one of claims 1 to 4, which further comprises a thickening polymer.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The hair cosmetic composition according to the present invention comprises:
At least 2 of polyhydric alcohol and / or its derivative
0 to 80% by weight and a polyether-modified silicone are contained. By having such a constitution, the hair can be conditioned with an appropriate setting force, and the hair is not sticky, and gloss can be imparted to the hair, and further, the retaining power of the imparted gloss is excellent.

The first essential ingredient of the cosmetic for hair according to the present invention is a polyhydric alcohol and / or its derivative. Examples of the polyhydric alcohol used include alkylene glycols such as ethylene glycol, propylene glycol, and 1,3-butylene glycol; polyalkylene glycols such as polyethylene glycol and polypropylene glycol; glycerin; diglycerin, triglycerin, pentaglycerin, decagserine. And the like; sugars such as glucose, maltose, maltitol, sucrose, mannitol, sorbitol, trehalose, etc., and the like; polyalkylene glycols such as polyethylene glycol and polypropylene glycol; Preference is given to using polyglycerin. Among them, polyethylene glycol, polypropylene glycol and diglycerin are particularly preferable.

The polyhydric alcohol derivative may be any of the above polyhydric alcohol derivatives, but it is preferable to use glycerin or a polyalkylene adduct of a saccharide. Specific examples thereof include polyoxyalkylene glyceryl ethers such as polyoxyethylene glycerin, polyoxypropylene glyceryl ether, and polyoxyethylene polyoxypropylene glyceryl ether, and polyoxypropylene sorbit. Above all,
It is particularly preferable to use polyoxypropylene glyceryl ether or polyoxypropylene sorbit.

The amount of the polyhydric alcohol and / or its derivative compounded in the cosmetic is preferably 20 to 80% by weight, more preferably 25 to 60% by weight. The reason for this is that the amount of less than 20% by weight is not sufficient to retain the luster imparted to the hair, and the amount of more than 80% by weight causes stickiness. Because there is no.

The second essential component of the present invention is a polyether modified silicone. The polyether-modified silicone used is not particularly limited, and examples thereof include polyoxyethylene / methylpolysiloxane copolymer and poly (oxyethylene / oxypropylene) methylpolysiloxane copolymer. It is preferable to use an ethylene / methyl polysiloxane copolymer.

The amount of the polyether-modified silicone compounded is
It is preferably 0.1 to 20% by weight in cosmetics,
It is more preferably 0.5 to 10% by weight. The reason for this is that if the blending amount is less than 0.1% by weight, the holding power of the gloss imparted to the hair is not excellent, and if the blending amount exceeds 20% by weight, stickiness is caused. This is because it is not preferable in any case.

The cosmetic for hair of the present invention may contain a thickening polymer in order to prevent dripping when applied to the hair. Examples of thickening polymers that can be blended include water-soluble natural polymers, semi-synthetic polymers, and synthetic polymers. Specifically, natural polymers such as gum arabic, tragacanth gum, guar gum, locust bean gum, karaya gum, iris moss, quince seed, gelatin, shellac, rosin and casein; carboxymethyl cellulose sodium, hydroxyethyl cellulose, methyl cellulose, ethyl cerose, sodium alginate. , Semi-synthetic polymers such as ester gum, nitrocellulose, hydroxypropyl cellulose, crystalline cellulose; polyvinyl alcohol, polyvinylpyrrolidone, sodium polyacrylate, carboxyvinyl polymer,
Examples thereof include synthetic polymers such as polyvinyl methyl cellulose and polyamide resins. Of these, it is preferable to use carboxyvinyl polymer, hydroxypropylmethyl cellulose, or the like.

When the thickening polymer is blended, the blending amount is not particularly limited, but it is preferably 0.01 to 5% by weight, more preferably 0.05 to 3% by weight in the cosmetic. . The reason for this is that if the compounding amount is less than 0.01% by weight, the thickening effect due to the compounding cannot be expected, and if the compounding amount exceeds 5% by weight, the viscosity of the cosmetic composition becomes too high and the usability is improved. This is because it is inferior to the above and is not preferable in any case.

The hair cosmetic composition according to the present invention contains, in addition to the above-mentioned components, oils and fats, as long as the stability is not impaired.
Waxes, hydrocarbons, fatty acids, higher alcohols, surfactants, ultraviolet absorbers, fragrances, chelating agents, bactericides, preservatives, humectants, cooling agents, vitamins, plant and animal extracts, pH
You may mix | blend a regulator etc. suitably according to the objective.

The hair cosmetic composition according to the present invention can be applied to various dosage forms such as hair lotion, hair gel, and hewax. Above all, the luster imparted to the hair and an appropriate hair styling power can be obtained. Since it has, it can be suitably used for a hair gel.
