Description

TECHNICAL FIELD The present invention relates to a hair rinse agent, and more particularly, to a hair rinse agent composition that significantly improves the dullness of hair and has an excellent hair conditioning effect.

(Prior art) When washing hair with a shampoo containing an anionic surfactant as a main component, in addition to stains on the hair, oil etc. that protects the hair surface are removed at the same time, and the flexibility of the hair is lost, resulting in no gloss. ， Becomes poor combing hair, and hair damage, split ends, and broken hair are more likely to occur.

For the purpose of preventing these adverse effects, a hair rinse agent containing a quaternary ammonium salt such as stearyl trimethyl ammonium chloride and distearyl dimethyl ammonium chloride, which are cationic surfactants, as a main active ingredient is used. However, when such a hair rinse agent containing such a quaternary ammonium salt as a main active ingredient is applied to so-called thin and flat hair, the hair is imparted with excessive flexibility and the hair becomes less stiff. As a result, the hair has a defect that it becomes cat streak lacking in fullness and volume, and the subsequent hair treatment (setting property, waving property) is deteriorated.

DISCLOSURE OF THE INVENTION Therefore, the present inventor has conducted diligent research for the purpose of providing a hair rinse agent having an excellent hair conditioning effect while imparting a waist to thin and flat hair, and as a result, bis (-alkyl-N). -Hydroxyethyl imidazoline) chloroacetic acid complex type amphoteric surfactant and a cationic polymer as essential components, hair rinsing agent containing a specific amount of each, it was found that the above objects can be achieved in all, the present invention, completed.

(Object of the Invention) That is, an object of the present invention is to provide a hair rinse agent that imparts elasticity to the hair and has an excellent hair conditioning effect (softness, moisturizing feeling, smoothness, combability). .

(Structure of the Invention) The present invention comprises (A) a bis (2-alkyl-N-hydroxyethylimidazoline) chloroacetic acid complex type amphoteric surfactant as an essential component, and (B)
A hair rinse composition containing a cationic polymer.

(Detailed Description of Configuration) The bis (2-alkyl-N-hydroxyethylimidazoline) chloroacetic acid complex type amphoteric surfactant which is the component (A) of the present invention is a known substance, for example, bis ( Lauryl-N-hydroxyethylimidazoline) chloroacetic acid complex, bis (myristyl-N-hydroxyethylimidazoline) chloroacetic acid complex, bis (palmityl-N-hydroxyethylimidazoline) chloroacetic acid complex, bis (stearyl-N-hydroxyethylimidazoline) Examples thereof include a chloroacetic acid complex and a bis (behenyl-N-hydroxyethylimidazoline) chloroacetic acid complex. Particularly preferred is a bis (stearyl-N-hydroxyethylimidazoline) chloroacetic acid complex.

In the hair rinse composition of the present invention, one or a mixture of two or more of these amphoteric surfactants is generally 1.0 to 6% by weight, based on the total amount (hereinafter abbreviated as wt%). To).

Preferably, 1.5 to 4 wt% is blended. If the blending amount is less than 1.0 wt%, the hair conditioning effect tends to be insufficient, and if it exceeds 6 wt%, the hair tends to become sticky.

Examples of the cationic polymer that is the component (B) of the present invention include the following.

(I) A cationized product composed of a vinylpyrrolidone / dimethylaminoethylmethacrylate copolymer and dimethylsulfate (for example, GAF coats 734 and 75).
5).

(Ii) A cationized product composed of glycidyl trimethyl ammonium chloride and hydroxyethyl cellulose (for example, polymer JR400 manufactured by UCC).

(Iii) Diallyldimethylammonium chloride / hydroxyethyl cellulose graft copolymer (for example, N
SC Coat L200).

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

(V) A homopolymer of dimethyl diallyl ammonium chloride or a copolymer of dimethyl diallyl ammonium chloride / acrylamide (for example, Mercoat 100 and 550 manufactured by MERQ).

(Vi) Acrylamide / β-methacryloyloxyethyltrimethylammonium methosulfate copolymer (for example, Reten 20 manufactured by HERCULES)
5).

(Vii) Vinylpyrrolidone / vinylimidazole No. 4
-Grade cationic polymers.

(For example, Luviquat FC 9 manufactured by Basf Co.
05).

(Viii) Polyethylene glycol / epichlorohydrin / coconut oil alkylamine / dipropylenetriamine condensate (for example, Polycoat H8 manufactured by HENKEL)
1).

And the like. Particularly preferred are cationized products consisting of glycidyl trimethyl ammonium chloride and hydroxyethyl cellulose and cationic cellulose such as diallyl dimethyl ammonium chloride / hydroxyethyl cellulose graft copolymer.

In the hair rinse composition of the present invention, one or more kinds of these cationized polymers are generally contained in an amount of 0.1 to 3 wt%, preferably 0.1 to 2 wt% based on the total amount.
% Is compounded. If the amount is less than 0.1%, the effect of imparting luster to the hair and the hair conditioning effect tend to be inadequate, and if it exceeds 3% by weight, the hair tends to become sticky and a dull residual feeling tends to occur. There is.

The hair rinse composition of the present invention comprises the above-mentioned two components as essential constituent components, and the blending weight ratio of these two components (A) and (B) is (A) :( B) = 2: 1. ~ 6: 1 is preferred. Further, other components can be appropriately added to the composition within a range that achieves the object of the present invention.

That is, hydrocarbons such as liquid paraffin, petrolatum 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 esters, polyoxyethylene fatty acid esters, polyoxyethylene Nonionic surfactants such as sorbitan monolaurate, cationic surfactants such as cetyltrimethylammonium chloride chloride, stearyltrimethyl chloride chloride, behenyltrimethylammonium chloride chloride, cellulose derivatives such as methylcellulose and hydroxyethylcellulose, ethylene glycol, propylene glycol, Moisturizers such as glycerin, polypeptides, other bactericides, anti-dandruff agents, chelating agents, UV absorbers, colorants,
Perfumes and the like can be mentioned, and one kind or two or more kinds thereof can be blended.

(Example) Next, an Example is given and this invention is demonstrated.

The present invention is not limited to these examples.

The test method used in this example is as follows.

In each case, "the stiffness of the waist of the hair", "the flexibility of the hair",
Evaluation was performed based on the following criteria by sensory comparison by 20 panelists of 20 women who complained that the hair quality was flat without thinning "moistness of hair", "smoothness of hair" and "combability".

◎: When the number of people who answered good was 18 or more ○: When 〃 was 14 to 17 △: When 〃 was 8 to 13 ×: When 〃 was 7 or less Examples 1-3, Comparative Example 1-3 A hair rinse agent having the composition shown in Table 1 was prepared by a usual method, and the effect of each essential component was investigated. The results are shown in the lower part of Table 1.

Examples 4 to 7 and Comparative Examples 4 to 7 Hair rinsing agents having the compounding compositions shown in Table 2 were prepared by a usual method, and the effect of each essential component was investigated. The results are shown in the lower row of Table 2.

(Characteristics) As is clear from Examples 1 to 7, the hair rinse composition of the present invention shows excellent performance.

On the other hand, bis (2-alkyl-N-), which is an essential product,
(Hydroxyethyl imidazoline) chloroacetic acid complex type amphoteric surfactant, or a cationic polymer and a quaternary ammonium salt alone (1 to 5), or in the case of a combination of an ordinary amphoteric surfactant and a cationic polymer (Comparative Example 6 to 7) and the like all show inferior performance, and the object of the present invention cannot be achieved.

(Effects of the Invention) As described above, the present invention imparts the waist to the hair and the hair conditioning effect (softness, moisturization,
It is obvious to provide a useful hair rinse composition excellent in smoothness and combability.
