Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a hair cosmetic composition which gives a moist feel and smoothness to the hair after washing and drying without giving tackiness.

[Problems to be Solved by Conventional Techniques and Inventions] In recent years, as a method for drying and maintaining hair after washing hair, a heating instrument such as a hand dryer or a curl dryer is often used. However, these thermal appliances damage the hair. In particular, at the hair tips where damage is likely to be noticed, there is a problem that the moist feeling is impaired and the hair becomes less cohesive. Such inconvenience is particularly noticeable when the hair is subjected to a chemical treatment such as cord wave or hair dye.

Conventionally, as a hair cosmetic composition for solving such inconvenience, the fourth representative one is stearyl dimethyl ammonium chloride and cetyl trimethyl ammonium chloride.
It has been proposed to use primary ammonium salts and higher alcohols such as cetyl alcohol, stearyl alcohol and behenyl alcohol as active ingredients. However, the hair cosmetics containing these quaternary ammonium salts and higher alcohols as active ingredients are not sufficiently adsorbed on the hair, and therefore satisfactory effects cannot be obtained.

Therefore, in order to improve the adsorptivity, it is generally practiced to jointly use animal and vegetable oils, hydrocarbon oils, ester oils and proteolytic products. However, these oils and protein decomposition products must be blended in large amounts in order to obtain the desired effect.
Further, in the case of a product that needs to be rinsed, there is a problem in that it remains on the hair. In addition, these oils and protein degradation products,
Due to its nature, it gives the hair a moist feel and makes it easier to stay organized, but on the other hand it gives a feeling of sticky finish. For this reason, there has been a strong demand for a hair cosmetic that can give a moist feel and smoothness without sticking to the hair.

[Means for Solving Problems] That is, the present invention is represented by one or more quaternary ammonium salts represented by the general formula (I) and (B) the general formula (II). One or more quaternary ammonium salts are contained, the total of both is 0.1 to 10% by weight, and (A)
The hair cosmetic is characterized in that the weight ratio of / (B) is 1/3 to 3/1.

[Wherein _one or _{two of} R ₁ , R ₂ , R ₃ or R ₄ are (here Represents a fatty acid residue having 8 to 24 carbon atoms, and n is an integer of 1 to 3. ) And the others are alkyl groups having 1 to 3 carbon atoms, benzyl groups, myristyl acetate or (Here, R ₆ represents a hydrogen atom or a methyl group, and m is 1 to 5
Is an integer. ). X is a halogen atom or an alkylsulfate group having 1 or 2 carbon atoms. ] [In the formula, one of R ₇ , R ₈ , R ₉ , or R ₁₀ has 8 carbon atoms.
~ 24 straight chain or branched chain alkyl group, hydroxyalkyl group or R ₁₁ (OCH ₂ CH ₂ ) _a (wherein R ₁₁ has 8 to 2 carbon atoms).
4 represents an alkyl group or a hydroxyalkyl group, and a is an integer of 1-10. ) And the others are alkyl groups having 1 to 3 carbon atoms, benzyl groups or (Here, b is an integer of 1 to 5). X is as described above. Representative examples of the component (A) of the present invention include coconut oil fatty acid amidopropyldimethylethanolammonium chloride, mink oil fatty acid amidopropyldimethylethanolammonium chloride, stearic acid amidopropyldimethylammonium chloride and the like.

Representative examples of the component (B) of the present invention include cetyltrimethylammonium chloride, stearyltrimethylammonium chloride, hydrogenated tallow alkyltrimethylammonium chloride and the like.

When the weight ratio (I) / (II) of the quaternary ammonium salt of the general formula (I) to the quaternary ammonium salt of the general formula (II) is less than 1/3 or more than 3/1, a moist feeling or Smoothness cannot be obtained, and neither is preferable.

If the total amount of the components (A) and (B) is less than 0.1% by weight, the hair cannot have a moist feel or smoothness, and if it exceeds 10%, it becomes sticky.

Other components may be optionally added to the composition of the present invention within a range that does not affect the effects of the present invention, depending on its type, purpose of use and the like. Such optional ingredients include:

Hydrocarbons such as liquid paraffin, petrolatum, solid paraffin, squalane and olefin oligomers; esters such as isopropyl myristate, isopropyl palmitate, stearyl stearate, octyldodecyl myristate, octyldodecyl oleate and triglyceride 2-ethylhexanoate: Vegetable oils such as camellia oil, olive oil, avocado oil and persic oil: higher alcohols such as behenyl alcohol and hexyldecanol: glyceryl fatty acid ester, sorbitan fatty acid ester, polyoxyethylene fatty acid ester, polyglycerin fatty acid ester and polyoxyethylene sorbita fatty acid ester Emulsifiers; methyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose and cationized ce Cellulose derivatives such as loin;
Thickeners such as natural polymers; moisturizers such as ethylene glycol, propylene glycol, 1,3-butylene glycol, glycerin and sorbitol; giving pearl luster such as polyethylene glycol, higher fatty acid ethanolamide, titanium mica and fish phosphorus foil Agents: other solvents, bactericides, chelating agents, ultraviolet absorbers, coloring agents, fragrances, etc., and one or more of these may be blended.

[Effects of the Invention] According to the hair cosmetic composition of the present invention, for example, in any of the uniform state, the non-uniform state, the emulsified state and the like, and in the type requiring rinsing and the type not requiring rinsing, It can give the hair a moist feeling and smoothness without giving a sticky feeling.
Therefore, it can be used for various purposes such as a hair rinse, a hair treatment, a dispenser type hair conditioner, and a hair lotion.

EXAMPLES Next, examples of the present invention will be shown to more specifically describe the effects of the present invention. The test method will be described prior to the description of each example.

[Moisture] 1 g of the sample was directly applied to a shampoo-treated hair bundle (10 g, 20 cm), and the whole hair bundle was evenly spread by hand. Then about 40
After rinsing lightly with hot water at ℃, it was left to dry overnight in a constant temperature and humidity atmosphere at 25 ℃ and 65% relative humidity.

The moist feeling of this hair bundle was sensory-evaluated by 20 testers. For the evaluation of the moist feeling of the hair bundle, 1% by weight of stearyl trimethyl ammonium chloride,
Based on the evaluation obtained by using a standard sample composed of 3% by weight of cetyl alcohol, 10% by weight of propylene glycol and water (the balance), the evaluation was made according to the following 5 grades by comparison with this.

◎: Good as compared to standard ○: Good as compared with standard △: Equivalent to standard X: Slightly inferior to standard XX: Inferior to standard [Smoothness] Evaluation method and evaluation similar to the above moist feeling It was judged according to the standard.

[Non-Stickiness] Judgment was made by the same evaluation method and evaluation criteria as for the moist feeling described above.

Examples 1 to 4 and Comparative Examples 1 to 10 14 types of hair cosmetic compositions having the compositions shown in Table 1 were prepared and their efficacy was tested. The results are shown in the table. The numbers in the table show% by weight.

From this table, the hair cosmetic composition of the present invention lacks either component (A) or (B) (Comparative Examples 1 to 6), and the total weight of components (A) and (B) is less than 0.1% by weight. (Comparative Example 7) and more than 10% by weight (Comparative Example 8), and the weight ratio of (I) / (II) is less than 1/3 (Comparative Example 9) or 3/1.
It can be seen that the desired effect can be obtained over all of the moist feeling, smoothness, and non-greasiness, as compared with those exceeding the above (Comparative Example 10).

The present invention is not limited to the above examples, and various components and blending amounts can be used without departing from the purpose.
