Description

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 specifically, it significantly improves the luster, smoothness and moisturizing finish of hair, and also has excellent hair conditioning effects. It relates to a rinse agent composition.

[0002]

When the hair is washed with a shampoo containing an anionic surfactant as a main component in order to remove stains on the hair, not only stains on the hair but also oil components protecting the hair surface are removed. At the same time, the hair becomes dull and has poor combability, and damage to the hair, split ends, and cut hair are likely to occur.

Therefore, for the purpose of preventing these adverse effects, a hair rinse agent containing a quaternary ammonium salt which is a cationic surfactant as an active ingredient is used.

These hair rinse agents have a conditioning effect on the hair (softness, moisturizing, smoothness,
The purpose is to impart combability and luster), but the quaternary ammonium salt alone cannot provide a sufficient effect in terms of luster, smoothness and moist feel of the finish. Therefore, it has been proposed to blend oils and fats such as higher alcohols, glycerides and liquid paraffin in conventional hair rinse agents in order to improve these drawbacks. In recent years, hair care products using silicone gum have also been proposed for the purpose of improving the luster and smoothness of hair.

However, the hair care products using these silicone gums are also those in which the silicone gums adhered to the hair are partially released during the continuous use by consumers.
The reality is that smoothness, combability, and luster have not been satisfactory.

[0006] That is, an object of the present invention is to provide a hair rinse agent which has an appropriate releasability by washing and which greatly improves the luster, smoothness and moisturizing finish of hair.

[0007]

In order to achieve the above object, the hair rinse composition of the present invention has the following constitution. That is, (A) general formula (I)

[Chemical 6] (Wherein all R ₅ are methyl groups or a part thereof is a phenyl group (provided that 90% or more of the total number of R ₅ are methyl groups),
R ₆ represents a methyl group or a hydroxyl group. Also, n is 100 to
Indicates an integer of 300. } One or more types of silicone represented by these are contained in 1.0-7 wt%, The hair rinse agent composition characterized by the above-mentioned.

The bis (2-alkyl-N-hydroxyethylimidazoline) chloroacetic acid complex type amphoteric surfactant represented by the general formula (I) in the present invention is a known substance, for example, bis (dodecyl-N). -Hydroxyethylimidazoline) chloroacetic acid complex, bis (tetradecyl-N-hydroxyethylimidazoline) chloroacetic acid complex, bis (hexadecyl-N-hydroxyethylimidazoline) chloroacetic acid complex, bis (octadecyl-N-hydroxyethylimidazoline) chloroacetic acid complex , Bis (docosyl-N-hydroxyethylimidazoline) chloroacetic acid complex and the like, and particularly preferred one is bis (octadecyl-N-hydroxyethylimidazoline).
It is a chloroacetic acid complex.

These amphoteric surfactants are added to the hair rinse composition of the present invention in an amount of 0.5 to 6% by weight (hereinafter abbreviated as wt%), preferably 1 to 4% by weight, based on the total amount. If the blending amount is less than 0.5 wt%, good results cannot be obtained for the hair conditioning effect, and if it exceeds 6 wt%, the hair becomes sticky, which is not preferable.

Examples of the silicone represented by the general formula (II) in the present invention include dimethylpolysiloxane, methylphenylpolysiloxane, terminal hydroxyl group-containing dimethylpolysiloxane, terminal hydroxyl group-containing methylphenylpolysiloxane and the like.

The average degree of polymerization m of the silicone used in the present invention is 900-1300, preferably 1000-1.
200. Those having an average degree of polymerization of less than 900 are not effective, and those having an average degree of polymerization of more than 1300 are not preferable because the moist feeling of the hair is poor.

In the hair rinse composition of the present invention, one or a mixture of two or more of these silicones is 0.3 to 3 wt% based on the total amount, preferably 0.5 to 2 wt.
% Is compounded. If the blending amount is less than 0.3 wt%, good results on the smoothness and moisturizing feeling of the hair after drying cannot be obtained, and if it exceeds 3 wt%, the hair becomes heavy, which is not preferable.

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

The average degree of polymerization n of the silicone used in the present invention is 100 to 300, preferably 150 to 250.
Is. Those having an average degree of polymerization of less than 100 are not effective, and those having an average degree of polymerization of more than 300 are not preferable because of poor smoothness.

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

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

Specifically, 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 sorbitan fatty acid esters. , Nonionic surfactants such as polyoxyethylene hydrogenated castor oil, cellulose derivatives such as methyl cellulose, hydroxyethyl cellulose, cationized cellulose, moisturizers such as ethylene glycol, propylene glycol and glycerin, polypeptides, other fungicides, anti-dandruff agents ，
Examples include chelating agents, ultraviolet absorbers, coloring agents, and fragrances, and one or more of these can be blended.

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

(Hair luster, smoothness, combability and moistness test of finish) In each example, the "gloss", "smoothness", "combability" of the hair and "moistness" of the finish were measured by a woman. After continuous use by 20 specialized panelists, sensory comparisons were made and evaluation was performed according to the following criteria. ⊚: 18 or more people answered good ○: 14 to 17 people answered good; △: 8 to 13 people answered good ×: 7 people answered good When the number of people is less than

Examples 1 to 3 and Comparative Examples 1 to 3 Hair rinse agents having the compounding compositions shown in the upper row of Table 1 were prepared by a usual method, the above test was carried out, and the results are shown in the lower row of Table 1.

[0023]

[Table 2]

As is clear from Examples 1 to 6, all the hair rinse composition of the present invention showed excellent performance. On the other hand, when either of the essential components bis (2-alkyl-N-hydroxyethylimidazoline) chloroacetic acid complex type amphoteric surfactant or silicone is lacking (Comparative Examples 1 to 3), or their compounding amount and silicone. When the average degree of polymerization (m, n) is outside the range of the present invention (Comparative Example 4)
Nos. 10 to 10 all showed inferior performance and could not achieve the object of the present invention.

[0025]

As described above, it is apparent that the present invention provides a useful hair rinse composition which is excellent in gloss, smoothness, combability and moisturizing finish.
