By the way, in addition to the above-mentioned extension, the hair conditioner has good re-arrangement property, which is a function of maintaining the re-arranged style by applying a hand comb even if the style once adjusted after application is disturbed. It may also be required.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a hair conditioner having good elongation when applied to hair, less stickiness of hair after hair shaping, and excellent re-dressing property. There is.

The hair conditioner of the present invention that has achieved the above object is characterized by containing the following components (A) to (C) and is an oil-in-water emulsion.
(A) A copolymer of an ester of methacrylic acid and polyoxyethylene alkyl ether and one or more selected from acrylic acid, acrylic acid alkyl ester, methacrylic acid and methacrylic acid alkyl ester,
(B) Carbomer,
(C) Alkaline.

According to the present invention, it is possible to provide a hair conditioner having good spreadability when applied to hair, less stickiness of hair after hair adjustment, and excellent re-arrangement property.

As described above, in general, when the hair conditioner spreads well when applied to the hair, it becomes difficult to maintain the style when the hair is re-shaped due to the good spread, and the re-shape property deteriorates. There is a tendency.

In the hair conditioner of the present invention, the ester of (A) methacrylic acid and polyoxyethylene alkyl ether and one or more selected from acrylic acid, acrylic acid alkyl ester, methacrylic acid and methacrylic acid alkyl ester are used together. By preparing an oil-in-water emulsion containing a polymer, (B) carbomer, and (C) alkali, the spread of the hair conditioner at the time of application to the hair is improved, and good re-arrangement is ensured. In addition, it is possible to suppress the stickiness of the hair after application.

That is, the hair conditioner of the present invention increases its fluidity when an external stress is applied by applying it to the hair, and loses its fluidity again when the external stress disappears.

Therefore, when stress is applied to the hair conditioner of the present invention by application to the hair, the fluidity is increased so that the hair conditioner extends well on the hair surface, and the hair conditioner can be adhered with high homogeneity over the entire surface of the hair. Then, when the hair styling is finished, the stress on the hair styling agent disappears, so that the fluidity of the hair styling agent attached to the hair decreases, and the style of the conditioned hair is maintained well. In addition, if the hair style is disturbed, if the hair is trimmed with a comb or hand comb, stress is applied to the hair conditioning agent on the surface of the hair and the fluidity is increased, so that the hair can be easily trimmed. When the stress on the hair conditioner is removed, the fluidity of the hair conditioner is reduced and the style of the hair conditioner is maintained well.

As described above, according to the hair conditioner of the present invention, good elongation at the time of application to the hair and high re-arrangement property can be ensured, and the stickiness of the hair after application can be reduced.

That is, when the viscosity is within the above range, it can be said that the hair conditioner has thixotropy.

The viscosity of the hair conditioner referred to in the present specification is determined by using a rheometer [for example, a stress-controlled rheometer "Rheo Stress 6000" (trade name) manufactured by HAAKE], measuring temperature: 25 ° C., cone plate sensor. The shear rate dγ / dt was maintained at 0.05s ^-1 for 1 minute in the steady flow curve mode under the conditions of the diameter of 35 mm and the inclination angle of the cone plate sensor: 2 °, and then the shear rate dγ / dt was set to 20s ^{−. When the} maintenance at ¹ for 1 minute is repeated 5 times, the value measured at the 5th time is adopted. The reason for measuring at the 5th time is that the measured value becomes stable at the 5th time.

The hair conditioner according to the present embodiment is, for example, an oil phase [(D) component, (E) component, etc.] added to an aqueous phase containing the components (A), (B) and (C). Can be prepared with.

The hair conditioner according to the present embodiment can be used, for example, by picking it up and extending it from the root side to the tip side of the hair. As described above, the hair conditioner according to the present embodiment has good elongation on the hair surface, so that even if it is applied to the hair by such a method, it has high homogeneity from the root side near the scalp to the hair tip side. It can be applied and the hair can be conditioned well.

Hereinafter, the present invention will be described in detail based on Examples. However, the following examples do not limit the present invention.

Example 1
(Acrylate / Behenez Methacrylic Acid-25) Copolymer [(A) Component], Carbomer [(B) Component], Potassium Hydrochloride [(C) Component], (Acrylate / Alkyl Acrylate (C10-30)) Cloth Liquid ester such as polymer, cyclomethicone, cetyl ethylhexanate, 1,3-propanediol, PEG-6, EDTA-2Na, phenoxyethanol, ethylparaben, and fragrance, and water are mixed and emulsified in water. A hair conditioner was prepared. The blending amount of each component in this hair conditioner is as shown in Table 1 below.

Comparative Example 1a
As shown in Table 1, a hair conditioner was prepared in the same manner as in Example 1 except that the carbomer as the component (B) was not blended and the amount of potassium hydroxide as the component (C) was changed.

Comparative Example 1b
As shown in Table 1, a hair conditioner was prepared in the same manner as in Example 1 except that the copolymer (Acrylate / Methacrylic Acid Behenes-25), which is the component (A), was not blended.

For each of the hair conditioners of Example 1 and Comparative Examples 1a and 1b, take an appropriate amount, extend the hair from the root side to the tip side of the hair, apply the hair, and then arrange the hair, and then apply the hair conditioner to the hair (on the surface of the hair). Evaluate the non-stickiness (the non-stickiness that you feel when you touch the hair after hair styling), and the hair styling that moves softly (the flexibility of the hair styling), and break the hair styling style once. The re-straightening property (ease of re-straightening) when the hair was re-dressed was evaluated.

The evaluation was carried out by three specialized evaluators, and in each evaluation, classification was performed according to the following evaluation criteria based on the case of Comparative Example 1b.
(Evaluation criteria)
〇: 2 or more out of 3 people evaluated that it was better than the standard.
-: 2 or more out of 3 people evaluated as equivalent to the standard.
×: 2 or more out of 3 people evaluated that the standard was better.

Table 1 shows the blending amount, dosage form, pH, and each of the above evaluation results of each component blended with water for each of the hairdressing agents of Example 1 and Comparative Examples 1a and 1b. The unit of the numerical value in the column of "blending amount" in Table 1 is "mass%" (the same applies to Tables 2 to 4 described later).

As shown in Table 1, the hair conditioner of Example 1 in which all the components (A) to (C) are blended has thixotropic properties and has a gel-like appearance with no fluidity when left to stand. When applied to hair, it becomes a cream with elasticity and hardness, and has better spread on the hair surface than the hair conditioner of Comparative Example 1b which does not contain the component (A), and also hair conditioner. The stickiness of the hair at that time was also suppressed. Furthermore, the hair conditioner of Example 1 also had good re-arrangement properties.

On the other hand, the hair conditioner of Comparative Example 1a containing the component (B) was inferior in re-arrangement property, probably because it spreads too well on the hair surface.

And water were mixed to prepare an oil-in-water emulsion type hair conditioner. The blending amount of each component in this hair conditioner is as shown in Table 2 below.

Example 2b
In the same manner as in Example 2a, the oil-in-water emulsion was prepared in the same manner as in Example 2a, except that the (Acrylate / Methacrylic acid steareth-20) copolymer was added as the component (A) instead of the (Acrylate / Methacrylic acid behenez-25) copolymer. A hair conditioner was prepared.

With respect to the hair styling agents of Examples 2a and 2b, the elongation when applied to the hair, the non-stickiness of the hair after the hair styling, the re-dressing property, and the soft moving hair styling property were evaluated in the same manner as in Example 1. .. The evaluation was carried out by three specialized evaluators, and in each evaluation, classification was performed according to the same evaluation criteria as in Example 1 and the like, based on the case of Example 2b.

Table 2 shows the blending amount, dosage form, pH, and each of the above evaluation results of each component blended with water for each of the hairdressing agents of Examples 2a and 2b.

As shown in Table 2, the hair conditioner of Example 2a using the (Acrylate / Behennes Methacrylic Acid-25) copolymer as the component (A) was Example 2b using the (Acrylate / Methacrylic Acid Steareth-20) copolymer. Compared with the hair styling agent, it was excellent in the good spreadability when applied to the hair and the non-stickiness of the hair after the hair styling.

Example 3a
(Acrylate / Behenez Methacrylate-25) Copolymer [(A) component], Carbomer [(B) component], Potassium hydroxide [(C) component], Hydrogenated polyisobutene [(D) component], Microcrystalline wax [Ingredient (E)], glyceryl stearate, behenes-20, ceteth-20, 1,3-propanediol, glycerin, EDTA-2Na, phenoxyethanol, methylparaben, fragrance, and water, and oil in water. A drop-type emulsion hair conditioner was prepared. The blending amount of each component in this hair conditioner is as shown in Table 3 below.

Example 3b
An oil-in-water emulsion type hair conditioner was prepared in the same manner as in Example 3a except that mineral oil was blended as the component (D) in place of hydrogenated polyisobutene.

Example 3c
An oil-in-water emulsion hair conditioner was prepared in the same manner as in Example 3a, except that cetyl ethylhexanoate was added instead of hydrogenated polyisobutene.

Example 3d
An oil-in-water emulsion hair conditioner was prepared in the same manner as in Example 3a except that candelilla wax was blended in place of microcrystalline wax.

Example 3e
An oil-in-water emulsion hair conditioner was prepared in the same manner as in Example 3c, except that candelilla wax was blended in place of microcrystalline wax.

For each of the hair styling agents of Examples 3a to 3e, in the same manner as in Example 1, the elongation when applied to the hair, the non-stickiness of the hair after styling, the re-shaping property, and the soft moving hair styling property are evaluated. , The setting power (the power to hold the movement of the hair when the hair was trimmed) was evaluated.

The evaluation was carried out by three specialized evaluators, and in each evaluation, classification was performed according to the same evaluation criteria as in Example 1 and the like, based on the case of Example 3e.

Table 3 shows the blending amount, dosage form, pH, and each of the above evaluation results of each component blended with water for each of the hair conditioning agents of Examples 3a to 3e.

As shown in Table 3, the setting power of the hair conditioner of Example 3c containing the component (E) was improved as compared with the hair conditioner of Example 3e containing the component (D) and the component (E). However, the hair styling agent that stretches and moves softly when applied to the hair deteriorates, and the hair styling agent of Example 3d containing the component (D) does not stretch when applied to the hair or is not sticky after the hair styling. Although the hair styling property that moves softly was improved, the hair styling property and the setting force were lowered. Then, in the hair conditioning agents of Examples 3a and 3b in which both the components (D) and (E) are blended, while suppressing the decrease in the setting force, the hair is stretched when applied to the hair, and the hair after the hair is adjusted. The non-stickiness, re-dressing property and soft-moving hair styling property could be improved as compared with the hair styling agent of Example 3e.

Further, the hair conditioners of Examples 3a and 3b were designated as Example 4a and Example 4b, respectively, and the evaluation results when the case of Example 4b was used as a reference were combined with the configurations of Examples 4a and 4b. It is shown in Table 4.

As shown in Table 4, the hair conditioner of Example 4a using hydrogenated polyisobutene as the component (D) is less sticky after hair adjustment and is less sticky than the hair conditioner of Example 4b using mineral oil. The hair styling that moves softly was good.
