Description

Description: TECHNICAL FIELD The present invention relates to a hair rinsing agent, and more particularly, to a hair rinsing agent composition which significantly improves the sliminess and spreadability during use and is excellent in hair conditioning effect. About things.

(Prior art) 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. The hair becomes dull and poorly combed, and 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.

Hair rinses are intended to impart conditioning effects (flexibility, moist feeling, smoothness, combability) to hair. However, the quaternary ammonium salt alone cannot provide a sufficient effect on flexibility and smoothness. Therefore, in order to improve these drawbacks, the conventional hair rinse agents include higher alcohols,
It has been proposed to incorporate fats and oils such as glyceride and liquid paraffin. However, these methods have not been able to obtain satisfactory results yet, and in particular, have insufficient hair smoothness. Further, the slimy feeling and the spread when using the rinse are inferior in the use feeling, so that the use amount is increased, which is not preferable in terms of economy.

(Problems to be Solved by the Invention) Accordingly, the present inventors have conducted intensive studies for the purpose of obtaining a hair rinse agent which has an excellent hair conditioning effect and greatly improves the feeling of use (sliminess, spreadability). It has been found that a hair rinse agent containing a quaternary ammonium salt and a specific amphoteric phosphate ester-based activator as required components and in a specific amount, respectively, can achieve the above object, and completed the present invention. .

That is, an object of the present invention is to provide a hair rinsing agent which has excellent hair conditioning effects (flexibility, moist feeling, smoothness, combability) and significantly improves the feeling of use (slimy feeling, spreading). It is in.

(Means for Solving the Problems) The present invention provides: [Wherein, _one or _{two of} R ₁ , R ₂ , R ₃ , and R ₄ represent a long-chain alkyl group having 12 to 24 carbon atoms, and the remainder represents an alkyl group having 1 to 3 carbon atoms and a benzyl group. , X represents a halogen atom. (B) a quaternary ammonium salt represented by the formula: [Wherein R ₁ is a linear or branched saturated hydrocarbon group having an average of 8 to 18 carbon atoms, and M ₁ represents an alkali metal, ammonium or triethanolamine. A hair rinse agent composition comprising 0.1 to 2% by weight of an amphoteric phosphate ester surfactant represented by the following formula:

As the cationic surfactant which is the component (A) of the present invention, one kind or a mixture of two or more kinds is applied, and all kinds which can be blended with a usual hair rinse agent and the like are used. For example, distearyl dimethyl ammonium chloride, stearyl trimethyl ammonium chloride,
Stearyldimethylbenzylammonium chloride,
Cetyltrimethylammonium chloride, behenyltrimethylammonium chloride, and the like.

The hair rinse composition of the present invention contains one or more of these cationic surfactants in an amount of 0.3 to 6% by weight (hereinafter abbreviated as wt%), preferably 0.5 to 4% by weight, based on the total amount. Be 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 6% by weight, the hair becomes sticky, which is not preferable.

The amphoteric phosphate-based activator which is the component (B) of the present invention includes N-lariul-N-methylaminoethyl phosphate monosodium and N-myristyl-N described in JP-A-62-237934. -Methylaminoethyl phosphate triethanolamine, N-palmethyl-N-methylaminoethyl phosphate monosodium, N-stearyl-N-methylaminoethyl phosphate monopotassium, N-lauryl-N-methylaminoethyl Phosphate ester triethanolamine and the like.

One or two or more of these compounds are mixed in an amount of 0.1 to 2% by weight, preferably 0.1 to 1.5% by weight based on the total amount. When the amount is less than 0.1% by weight, good results are not obtained for the hair conditioning effect, slimy feeling at the time of use, and spreadability, and when it exceeds 2% by weight, the hair becomes sticky, which is not preferable.

The hair rinse composition of the present invention comprises the above-mentioned two components as compulsory components, and the mixing weight ratio of these two components (A) and (B) is (A) :( B) = 3: 1-10: 1 is preferred. In addition, other components can be appropriately added to the composition as long as the object of the present invention is achieved.

That is, liquid paraffin, hydrocarbons such as petrolatum and squalane, ester oils such as isopropyl myristate and isopropyl palmitate, vegetable oils such as camellia oil, olive oil, avocado oil, polyglycerin fatty acid ester, polyoxyethylene sorbitan monolaurate, etc. Nonionic surfactants, cellulose derivatives such as methylcellulose, hydroxyethylcellulose and cationized cellulose, humectants such as ethylene glycol, propylene glycol and glycerin, polypeptides, other bactericides, dandruff removers, chelating agents, ultraviolet absorbers, Coloring agents, fragrances and the like can be mentioned, and one or more of these can be blended.

(Examples) 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.

(1) Feeling of use (sliminess, growth) and hair conditioning effect.

"Sliminess", "growth", "flexibility of hair", "moistness of hair", "smoothness of hair", and "comb passability" in each case sensuously compared by 20 female panelists Then, evaluation was performed based on the following criteria.

◎: 18 or more people answered good ○: 14-17 people answered good △: 8-13 people answered good ×: 7 people answered good In the case of humans or less Examples 1-3 and Comparative Examples 1-2 A hair rinse having the composition shown in Table 1 was prepared by a usual method, and the effect of each required component was investigated. Show.

Examples 4 to 7, Comparative Examples 3 to 4 Hair rinses having the composition shown in Table 2 were prepared in a usual manner, and the effects of each required component were examined. The results are shown in the lower row of Table 2.

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

On the other hand, a cationic activator or an amphoteric phosphate-based activator, which is an essential component, alone (Comparative Examples 1 and 2), or when the blending amount thereof is out of the range of the present invention (Comparative Examples 3 to 5)
All show inferior performance and cannot achieve the object of the present invention.

(Effects of the Invention) As described above, the present invention provides hair conditioning effects (flexibility, moist feeling, smoothness, combability).
It is apparent that the present invention provides a useful hair rinse composition excellent in use feeling (slimy feeling, spreadability).
