DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair rinsing agent, and more particularly to a hair rinsing agent which greatly improves the gloss, smoothness and smoothness of the finish of hair and also has an excellent hair conditioning effect. It relates to a rinsing agent composition.

[0002]

2. Description of the Related Art In order to remove hair stains, if the hair is washed with a shampoo containing an anionic surfactant as a main component, not only the hair stains but also the oil protecting the hair surface is reduced. At the same time, the hair is removed, resulting in a dull and poorly combed hair, and hair damage, split ends, and cut hairs are likely to occur.

[0003] For the purpose of preventing these problems, a hair rinse agent containing a quaternary ammonium salt as a cationic surfactant as an active ingredient has been used.

[0004] These hair rinses have a conditioning effect (flexibility, moist feeling, smoothness,
It is intended to impart combability and gloss), but a quaternary ammonium salt alone cannot provide a sufficient effect on gloss, smoothness and smoothness of finish. Accordingly, it has been proposed to incorporate oils and fats such as higher alcohols, glycerides, and liquid paraffin in conventional hair rinses in order to improve these disadvantages. In recent years, hair care products using silicone gum have been proposed for the purpose of improving the gloss and smoothness of hair.

[0005] However, in hair care products using these silicone gums, the silicone gums attached to the hair are partly detached in the process of continuous use by consumers.
In fact, it was not possible to obtain satisfactory smoothness, combability, and luster.

[0006] That is, an object of the present invention is to provide a hair rinsing agent which has an appropriate releasing property upon washing and which significantly improves gloss, smoothness and smoothness of finish of hair.

[0007]

Means for Solving the Problems To achieve the above object, the hair rinse composition of the present invention has the following constitution. That is, (A) general formula (I)

Embedded image (Wherein, ₁ to 2 of R _{1 to} R ₄ represent a long-chain alkyl group having 12 to 24 carbon atoms, the remainder represents an alkyl group having 1 to 3 carbon atoms or a benzyl group, and X represents a halogen atom. One or more quaternary ammonium salts represented by the formula (B): 0.3 to 5% by weight;

Embedded image ｛In the formula, all of R ₅ are methyl groups or a part thereof is a phenyl group (however, 90% or more of the total number of R ₅ is a methyl group);

R ₆ represents a methyl group or a hydroxyl group. Also, n is 100 to
Indicates an integer of 300. A hair rinse composition containing 1 to 7% by weight of one or more of silicones represented by｝.

As the quaternary ammonium salt represented by the general formula (I) in the present invention, all that can be blended with a usual hair rinse agent and the like are used. For example, dimethyldioctadecyl ammonium chloride,
Octadecyltrimethylammonium chloride, dodecyltrimethylammonium chloride, benzyldimethyloctadecylammonium chloride, didodecyldimethylammonium chloride, benzyldiethyldodecylammonium chloride, hexadecyltrimethylammonium chloride, dodecyltrimethylammonium bromide, docosyltrimethylammonium chloride, didodecyldimethylammonium bromide And the like.

The hair rinse composition of the present invention contains one or more of these cationic surfactants in an amount of from 0.3 to 5% by weight (hereinafter abbreviated as wt%), preferably based on the total amount. 0.5 to 4 wt% is blended. If the amount is less than 0.3% by weight, good results for the hair conditioning effect cannot be obtained. If the amount exceeds 5% by weight, the hair becomes sticky, which is not preferable.

The silicone represented by the general formula (II) in the present invention includes, for example, dimethylpolysiloxane, methylphenylpolysiloxane, dimethylpolysiloxane having a terminal hydroxyl group, and methylphenylpolysiloxane having a terminal hydroxyl group.

The average degree of polymerization m of the silicone used in the present invention is from 1,400 to 2,200, preferably from 1,500 to 2,200.
2000. Those having an average degree of polymerization of less than 1400 do not have a smooth finish, and have an average degree of polymerization of 2200.
If it exceeds 30, the smoothness of the hair is inferior, which is not preferable.

The hair rinse composition of the present invention contains one or more of these silicones in an amount of 0.3 to 3 wt%, preferably 0.5 to 2 wt%, based on the total amount.
%. If the amount is less than 0.3% by weight, good results in smoothness and smoothness of the dried hair cannot be obtained, and if it exceeds 3% by weight, the smoothness of the hair is inferior and is not preferable.

Examples of the silicone represented by the general formula (III) in the present invention include dimethylpolysiloxane, methylphenylpolysiloxane, dimethylpolysiloxane having a terminal hydroxyl group, and methylphenylpolysiloxane having a terminal hydroxyl group.

The average degree of polymerization n of the silicone used in the present invention is from 100 to 300, preferably from 150 to 250.
It is. Those having an average degree of polymerization of less than 100 have no effect, and those having an average degree of polymerization of more than 300 are unfavorable due to poor smoothness.

The hair rinse composition of the present invention contains 1 to 7 wt%, preferably 2 to 5 wt% of one or more of these silicones based on the total amount. If the amount is less than 1% by weight, good results cannot be obtained for the smoothness and luster of the dried hair. If the amount exceeds 7% by weight, the hair becomes sticky, which is not preferable. The mixing weight ratio of these two components (B) and (C) is preferably 1: 2 to 1: 6.

The hair rinse composition of the present invention comprises the above-mentioned three components as essential components.
Other components can be appropriately blended within a range that achieves the object of the present invention.

That is, liquid paraffin, hydrocarbons such as petrolatum, squalane and the like, ester oils such as isopropyl myristate and isopropyl palmitate, vegetable oils such as camellia oil, olive oil and avocado oil, polyglycerin fatty acid ester, polyoxyethylene sorbitan fatty acid ester , Nonionic surfactants such as polyoxyethylene hydrogenated castor oil, cellulose derivatives such as methylcellulose, hydroxyethylcellulose, and cationized cellulose; humectants such as ethylene glycol, propylene glycol, and glycerin; polypeptides; other disinfectants; ,
Examples thereof include a chelating agent, an ultraviolet absorber, a coloring agent, and a fragrance, and one or more of these can be blended.

Next, the present invention will be described with reference to examples, but the present invention is not limited to these examples. The test method used in this example is as follows.

(Test of gloss, smoothness, combability and finish feeling of hair) In each example, the "gloss", "smoothness", "combness" and "finishness" of the finish of the hair were evaluated by women. After continuous use by 20 specialized panelists, they were sensually compared and evaluated according to the following criteria. ◎: 18 or more answered good ○: 14 to 17 answered good △: 8 to 13 answered good ×: 7 answered good If you are less than
