Description

Description: FIELD OF THE INVENTION The present invention relates to a hair rinsing agent, and more particularly to a hair rinsing agent, which significantly improves the limpness of the hair, as well as the hair conditioning effect and the dryness of the hair after drying. The present invention relates to a hair rinsing agent composition having excellent hair rinsing agent composition.

[Problems to be solved by conventional technology and invention]

When hair is washed with a shampoo containing an anionic surfactant as a main component to remove hair stains, oils protecting the hair surface as well as hair stains are removed at the same time, and the flexibility of the hair is lost and the gloss is reduced. The hair is as bad as it is without comb,
Hair damage, split ends, and cuts are likely to occur.

For the purpose of preventing these adverse effects, a hair rinse agent containing a quaternary ammonium salt as a cationic surfactant as an active ingredient has been used. However, when such a hair rinse agent containing a quaternary ammonium salt as a main active ingredient is applied to so-called thin and stiff hair, the hair becomes excessively flexible, the hair after drying becomes heavy and the hair becomes heavy. Loses his waist. As a result, the hair had a drawback that the hair became cat hair lacking in fullness and volume, and the subsequent hair treatment (setting properties and waving properties) deteriorated.

The present invention provides a hair rinsing agent that imparts a stiffness to the hair, has excellent hair conditioning effects (flexibility, moist feeling, smoothness, combability), and has a light finish and a dry feeling after drying the hair. It is intended to be.

[Means for solving the problem]

The present invention provides: [Wherein, R ₁ is a lanolin fatty acid residue, R ₂ , R ₃ , R ₄ , and R ₅ are an alkyl group having 1 to 4 carbon atoms, and 1 is an integer of 2 to 5. And (B) a cationic polymer, and (C) a general formula [Wherein, R ₆ represents a methyl group or a phenyl group (however, 90% or more of the total number of R ₆ is a methyl group), and R ₇ represents a methyl group or a hydroxyl group. N represents an integer of 900 to 2500. ] A hair rinse composition characterized by containing one or more polymer silicones represented by the formula:

The lanolin-based quaternary ammonium salt as the component (A) of the present invention is a known substance, and includes, for example, lanolin fatty acid aminopropylethyldimethylammonium ethyl sulfate, lanolin fatty acid aminoethyltriethylammonium ethyl sulfate, and lanolin fatty acid aminoethyl sulfate. Ethyl diethyl methyl ammonium, lanolin fatty acid aminoethyltrimethylammonium ethyl sulfate, lanolin ethyl fatty acid aminopropyltriethylammonium sulfate,
Examples thereof include lanolin methyl fatty acid aminoethyltrimethylammonium, lanolin methylaminopropylethyldimethylammonium methyl sulfate, and particularly preferred is lanolin ethylaminopropylethyldimethylammonium ethyl sulfate.

In the hair rinse composition of the present invention, one or a mixture of two or more of these lanolin-based quaternary ammonium salts is preferably used in an amount of 0.1 to 4.0% by weight (hereinafter referred to as wt.
%), Particularly preferably 0.3 to 3.0% by weight. If the amount is less than 0.1% by weight, good results for the hair conditioning effect cannot be obtained. If the amount exceeds 4.0% by weight, the hair becomes sticky and has a heavy finish, which is not preferable.

The following are examples of the cationic polymer that is the component (B) of the present invention.

(I) A cationized product composed of a vinylpyrrolidone / dimethylaminoethyl methacrylate copolymer and dimethyl sulfate (for example, Guffcoat 734 and 755 manufactured by GAF).

(Ii) A cationized product composed of glycidyltrimethylammonium chloride and hydroxyethylcellulose (for example, polymer JR400 manufactured by UCC).

(Iii) diallyldimethylammonium chloride / hydroxyethylcellulose graft copolymer (for example, NS
Cell coat L200 manufactured by Company C).

(Iv) Quaternary ammonium derivatives of hydroxypropyl guar (for example, Jaguar C 13S manufactured by MEYHALL).

(V) A homopolymer of dimethyldiallylammonium chloride or a copolymer of dimethyldiallylammonium chloride / acrylamide (for example, Mercoat 100 manufactured by MERQ)
And 550).

(Vi) Acrylamide / β-methacryloyloxyethyltrimethylammonium methosulfate copolymer (for example, Reten 205 manufactured by HERCULES).

(Vii) the fourth of vinylpyrrolidone / vinylimidazole
Grade cationic polymer.

 (Eg Luviquat FC 905 from Basf).

(Viii) Polyethylene glycol / epichlorohydrin / coconut oil alkylamine / dipropylenetriamine condensate (for example, Polycoat H81 manufactured by HENKEL).

Particularly preferred are cationic products such as a cationized product composed of glycidyltrimethylammonium chloride and hydroxyethylcellulose and a diallyldimethylammonium chloride / hydroxyethylcellulose graft copolymer.

The hair rinse composition of the present invention contains one or more of these cationized polymers in an amount of preferably 0.1 to 3.0 wt%, particularly preferably 0.1 to 2.0 wt%, based on the total amount.
Be blended. If the amount is less than 0.1 wt%, the effect of imparting waist to the hair and the hair conditioning effect tend to be insufficient, and if the amount exceeds 3.0 wt%, the hair tends to be sticky and have a rough feeling of residualness. is there.

The polymer silicone as the component (C) of the present invention has the following general formula: [Wherein, R ₆ represents a methyl group or a phenyl group (however, 90% or more of the total number of R ₆ is a methyl group), and R ₇ represents a methyl group or a hydroxyl group. N represents an integer of 900 to 2500. One type or a mixture of two or more types of the high molecular silicone represented by the formula:

For example, dimethylpolysiloxane, methylphenylpolysiloxane, dimethylpolysiloxane having a terminal hydroxyl group, methylphenylpolysiloxane having a terminal hydroxyl group, and the like can be given.

R ₆ in the formula is all methyl groups or a part thereof is a phenyl group, and the ratio of the methyl group is essential to be 90% or more of the total number of R ₆ .

In the hair rinse composition of the present invention, one or a mixture of two or more of these high molecular silicones is preferably used in an amount of 0.1 to 6.0% by weight, particularly preferably 0.3 to 6.0% by weight, based on the total amount.
5.0wt% is blended. If the amount is less than 0.1% by weight, good results cannot be obtained for the dry feeling after drying, and if it exceeds 6.0% by weight, the hair becomes sticky, which is not preferable.

On the other hand, the average polymerization degree (n) of the high molecular silicone used in the present invention is from 900 to 2500, preferably from 1,000 to 2,000.

Those having an average degree of polymerization of less than 900 have no effect, and those having an average degree of polymerization of more than 2500 are not preferred because smoothness and combability are poor when used continuously.

The hair rinse composition of the present invention contains the above-mentioned three components as essential components, but other components can be appropriately added to the composition as long as the object of the present invention is achieved.

Hydrocarbons such as petrolatum, squalane, low-boiling isoparaffin, and liquid paraffin; ester oils such as isopropyl myristate and isopropyl palmitate; vegetable oils such as camellia oil, olive oil and avocado oil; silicone oils such as low-boiling silicone and cyclic silicone Surfactants such as polyglycerol fatty acid esters, polyoxyethylene sorbitan monolaurate, cellulose derivatives such as methylcellulose, hydroxyethylcellulose, cationized cellulose, humectants such as ethylene glycol, propylene glycol, glycerin, polypeptides, In addition, a bactericide, a coloring agent, a fragrance and the like can be mentioned, and one or more of these can be blended.
