Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transparent hair care cosmetic composition which has good transparency and temperature stability, and has an excellent effect of making hair supple, smooth and combable.

[0002]

2. Description of the Related Art Hair care cosmetics having a rinsing effect such as smoothness and combing of hair are generally available as hair rinses, hair treatments and hair conditioners. These hair care cosmetics are basically creamy compositions in which oil is emulsified mainly in a gel of a complex of a quaternary ammonium salt and a higher alcohol. When these are adsorbed on the hair, the above-mentioned so-called rinsing effect is obtained. However, these agents are opaque in appearance and unsuitable when transparency is required. Conventionally, as transparent hair care cosmetics, there are an oil rinse in which a large amount of a nonionic surfactant is used to solubilize a liquid oil component and a rinse agent in which a large amount of a cationic polymer is blended. However, oil rinsing is not preferable for use because it has a strong residual oil property on the hair after rinsing, and a rinsing agent containing a large amount of a cationic polymer has an insufficient rinsing effect on hair. . Therefore, a hair care cosmetic having a transparent appearance and a good rinsing effect has been desired.

[0003]

SUMMARY OF THE INVENTION In view of the above circumstances, the present inventor has proposed a transparent material which has good transparency and temperature stability, and has an excellent effect of making hair supple, smooth and combable. The purpose is to provide hair care cosmetics.

[0004]

Means for Solving the Problems The present inventors have conducted intensive studies to achieve the above object, and have found that glycerin and / or polyglycerin having an average degree of polymerization of 2 to 10, polyether-modified silicone, cationic polymer compound The present inventors have found that a transparent hair care cosmetic comprising a cationic surfactant can solve the above problems, and have completed the present invention.

That is, according to the present invention, glycerin and / or polyglycerin having an average degree of polymerization of 2 to 10 are 3 to 30% by weight, polyether-modified silicone is 1 to 10% by weight, and cationic polymer compound is 0.1 to 5% by weight. A transparent hair care cosmetic comprising 0.1 to 5% by weight of a cationic surfactant.

Hereinafter, the present invention will be described in detail. Glycerin and / or polyglycerol having an average degree of polymerization of 2 to 10 used in the present invention include glycerin, diglycerin,
Examples thereof include triglycerin, tetraglycerin, hexaglycerin, and decaglycerin, and one or more of these are used. Of these, diglycerin is most preferred from the viewpoint of a rinsing effect on hair.
Further, the purity of diglycerin in glycerin and polyglycerin is preferably 60% by weight, more preferably 80% by weight or more.

In the transparent hair care cosmetic of the present invention, the amount of glycerin and / or polyglycerin is selected in the range of 3 to 30% by weight, preferably 5 to 20% by weight based on the total amount of the transparent hair care cosmetic. It is. If it is less than 3% by weight, the rinsing effect on hair and the temperature stability become insufficient. If the amount is more than 30% by weight, the texture of the treated hair becomes heavy and the feeling of use becomes poor.

Examples of the polyether-modified silicone used in the present invention include a polyoxyethylene / methylpolysiloxane copolymer and a poly (oxyethylene / oxypropylene) methylpolysiloxane copolymer. Use one or more.

In the present invention, the above-mentioned polyether-modified silicone is used in an amount of 1 to 100% based on the total amount of the transparent hair care cosmetic.
It is used in an amount of 10% by weight, preferably 3 to 7% by weight. When the amount is less than 1% by weight, a squeaky feeling is exerted when the composition is applied to the hair, and the usability deteriorates. If the amount is more than 10% by weight, the application to hair becomes heavy and the usability deteriorates.

The cationic polymer compound used in the present invention includes cationic cellulose derivatives such as cationized hydroxyethyl cellulose, cationic polysaccharide derivatives such as cationized guar gum, vinylpyrrolidone / alkyldialkylamino (meth) acrylate copolymers. Examples thereof include a coalescence and a cationic silicone polymer, and one or more of these are used.

In the present invention, the cationic polymer compound is used in an amount of 0.1 to 0.1% based on the total amount of the transparent hair care cosmetic.
It is used in an amount of 5% by weight, preferably 0.5 to 3% by weight. If it is less than 0.1% by weight, the rinsing effect on hair is insufficient. If it is added in an amount exceeding 5% by weight, the viscosity is extremely increased and the use becomes difficult.

The cationic surfactant used in the present invention includes cetyltrimethylammonium chloride, stearyltrimethylammonium chloride, behenyltrimethylammonium chloride, hydrogenated tallow alkyltrimethylammonium chloride, distearyldimethylammonium chloride, and di-linear alkyldimethyl. Ammonium chloride, di-linear alkyl-bis-
Examples thereof include (2-hydroxyethyl) ammonium chloride and mono-linear alkylpentaethoxylated ammonium chloride, and one or more of these are used.

In the present invention, the above cationic surfactant is used in an amount of 0.1 to 5 with respect to the total amount of the transparent hair care cosmetic.
%, Preferably in the range of 0.5 to 3% by weight. If it is less than 0.1% by weight, the rinsing effect on hair is insufficient. If the content is more than 5% by weight, the temperature stability becomes insufficient, which is not preferable.

Further, the transparent hair care cosmetic composition of the present invention includes:
Within the range not impairing the present invention, ingredients used in hair care cosmetics, for example, humectants such as glycerin, polyhydric alcohols other than polyglycerin, alkylamidopropylbetaine, alkyldimethylaminoacetic acid betaine, alkyldimethylamine oxide and the like Amphoteric surfactants, nonionic surfactants such as alkylalkanolamides, crude drugs,
Lanolin derivatives, protein derivatives, water-soluble polymers, preservatives,
A bactericide, an antioxidant, a pH adjuster, a pigment, a fragrance and the like may be added.

The transparent hair care cosmetic of the present invention can be produced according to a conventional method, and can be obtained, for example, by uniformly dissolving all components using a stirrer such as an anchor mixer.
