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 composition which significantly improves luster and smoothness of hair and is excellent in other hair conditioning effects.

[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 rinse agents are intended to impart a conditioning effect (flexibility, smoothness, gloss, combability) to the hair. A sufficient effect on smoothness cannot be obtained. Therefore, it has been proposed that conventional hair rinse agents contain oils and fats such as higher alcohols, glycerides, and liquid paraffin 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.

However, these hair care products also have
During the process of continuous use by consumers, the silicone gum attached to the hair was partly detached, and it was the fact that satisfactory products in smoothness, combability, and luster were not obtained. .

[0006] That is, an object of the present invention is to provide a hair rinsing agent which has an appropriate desorption property upon washing and greatly improves gloss and smoothness 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, the general formula (A)

Embedded image (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. ), One or more lanolin-based quaternary ammonium salts represented by the formula (B):

Embedded image Wherein R ₆ is a methyl group or a part thereof is a phenyl group (provided that 90% or more of the total number of R ₆ is a methyl group);
R ₇ all represent a methyl group or one of them represents a hydroxyl group. N represents an integer of 300 to 800. 1 to 6% by weight of one or more silicones represented by
And (C) diglycerin containing 5 to 5 propylene oxide
A hair rinse agent composition comprising 0.1 to 3% by weight of a polyether compound obtained by addition of 15 mol of an addition polymer.

The lanolin-based quaternary ammonium salt represented by the general formula (A) in the present invention is a known substance, and examples thereof include lanolin fatty acid aminopropylethyldimethylammonium ethyl sulfate, lanolin fatty acid aminoethyltriethylammonium ethyl sulfate, and the like. Aminoethyl diethylmethylammonium ethyl lanolin sulfate fatty acid, aminoethyltrimethylammonium ethyllanoline sulfate fatty acid, aminopropyltriethylammonium ethyllanoline fatty acid, aminoethyltrimethylammonium methylsulfonate fatty acid, aminopropylethyldimethylammonium methyllanoline fatty acid and the like. Particularly preferred is aminopropylethyldimethylammonium ethyl lanolin sulfate fatty acid.

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 0.3 to 4% by weight (hereinafter abbreviated as wt%) based on the total amount. , Preferably 0.5 to 3.0 wt%
Be blended. If the amount is less than 0.3% by weight, good results cannot be obtained for the hair conditioning effect, and 4 w
If it exceeds t%, the hair becomes sticky, resulting in a heavy finish, which is not preferable.

The silicone represented by the general formula (B) in the present invention includes, for example, dimethylpolysiloxane, methylphenylpolysiloxane, dimethylpolysiloxane having a terminal hydroxyl group, and methylphenylpolysiloxane having a terminal hydroxyl group. R ₆ in the formula is all methyl groups or a part thereof is a phenyl group, and it is essential that the ratio of methyl groups is 90% or more of the total number of R ₆ .

The hair rinse composition of the present invention contains 1 to 6 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 wt%, smoothness and gloss after drying cannot be obtained, and if it exceeds 6 wt%, the hair becomes sticky, which is not preferable.

On the other hand, the average degree of polymerization n of the silicone used in the present invention is from 300 to 800, preferably from 400 to 800.
700. Those having an average degree of polymerization of less than 300 have no effect, and those having an average degree of polymerization of more than 800 are not preferred because smoothness and gloss are poor when used continuously.

The polyether compound obtained by addition-polymerizing 5 to 15 mol of propylene oxide to diglycerin, which is the component (C) of the present invention, is a known substance and includes, for example, polyoxypropylene (5) diglyceryl ether and polyoxypropylene (5). Oxypropylene (10) diglyceryl ether, polyoxypropylene (15) diglyceryl ether and the like can be mentioned. Those having an added mole of propylene oxide of less than 5 have no effect, and those having an added mole of more than 15 are not preferred because smoothness is poor.

In the hair rinsing agent of the present invention, one or a mixture of two or more of these polyether compounds is contained in an amount of 0.1 to 3% by weight, preferably 0.2 to 3% by weight based on the total amount.
1.5 wt% is blended. If the amount is less than 0.1% by weight, there is no effect. If the amount exceeds 3% by weight, the hair becomes heavy, which is not preferable.

[0015] The hair rinse composition of the present invention comprises the above three components as essential components.
Other components can be appropriately blended within a range that achieves the object of the present invention.

That is, hydrocarbons such as liquid paraffin, vaseline and squalane, 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 monolau Nonionic surfactants such as acrylates, cellulose derivatives such as methylcellulose, hydroxyethylcellulose, and cationized cellulose; humectants such as ethylene glycol, propylene glycol, and glycerin; polypeptides; other bactericides; dandruff; chelating agents; Agent, colorant,
One or more of these can be blended.

Examples 4 to 6 and Comparative Examples 4 to 10 Hair rinses having the composition shown in Table 2 were prepared by a usual method, and the above test was conducted. The results are shown in the lower part of Table 2.

[Table 2]

As is clear from Examples 1 to 6, all of the hair rinse compositions of the present invention exhibited excellent performance. On the other hand, when any of the lanolin-based quaternary ammonium salts, silicones, and polyether compounds, which are essential components, is missing (Comparative Examples 1 to 3), or the blending amount thereof and the average degree of polymerization (n) of the silicone, In the cases out of the range (Comparative Examples 4 to 10), the performances were all inferior, and the object of the present invention could not be achieved.
