Description

Purified composition

The present invention relates to a hair conditioning composition. More particularly, the present invention relates to a hair care composition which can be lightly finished and brightly finished, has no stickiness, and does not cause hair stiffness or stiffness.

Conventionally, in the case of a hair treatment composition such as hair wax, a solid oil component such as wax is generally blended for the purpose of setting (fixing) and fixing hair. However, increasing the oil content to increase the fixing force improves the setting force There has been a problem in that shine and tackiness caused by the oil are generated and the smoothness is also reduced in the feeling of use, which causes deterioration of the spread.

In order to solve the above-mentioned problems, there has been proposed a soap preparation containing a powder component such as silica (silicic anhydride). For example, Patent Document 1 includes (a) a specific anionic surfactant, (b) a higher alcohol, (d) water, and (e) a liquid oil component, (C-2) a specific cleansing resin, and (c-3) anhydrous silicic acid in combination with a water-in-oil type emulsion, 3) Anhydrous silicic acid is said to be effective in directing a part such as lightness and volume feeling.

Patent Document 2 contains (A) at least one selected from (A) anhydrous silicic acid and / or hydrophobic silicic anhydride, (B) lead, hydrocarbon, fatty acid ester oil and silicone oil, (C) a surfactant, and (A) an emulsified composition for adjusting the content ratio of (A) to (B) within a predetermined range, which can be positively stuck without being tacky due to the positive effect of (A) anhydrous silicic acid and / or hydrophobic silicic anhydride, It is said that there is no unnatural smudge of natural feeling, and a light finishing feeling of natural feeling is obtained, and it is also excellent in retaliation.

However, in the case of a pure preparation using a correcting effect by anhydrous silicic acid, a coarse and light finish can be obtained. However, by adding anhydrous silicic acid (powdery formulating agent) exhibiting a correcting effect, stiffness due to the powder is generated, There was a case.

On the other hand, the acrylic acid Na-grafted starch is known as a highly water-absorbing polymer material, and Patent Document 3 discloses various cosmetic formulations in which an acrylic acid Na-grafted starch is blended. However, the effect of the treatment with Na-grafted starch of acrylic acid was not known at all.

Japanese Patent No. 5761838 Japanese Patent Application Laid-Open No. 2012-102057 Japanese Patent Application Laid-Open No. 2011-256154

Accordingly, a problem to be solved by the present invention is to provide a pure-applied composition capable of achieving a smooth and light finish and at the same time, without the stiffness and stiffness of hair, and without tackiness,

Means for Solving the Problem As a result of intensive investigations in order to solve the above problems, the present inventors have found that, by mixing a predetermined amount of an acrylic acid Na-grafted starch conventionally used as an aqueous (thickly water-soluble) thickener, , And no stiffness or stiffness due to the powder combination is found to occur, thereby completing the present invention.

That is,

(A) not less than 0.01% by mass and less than 1.5% by mass of an acrylic acid Na-grafted starch,

(B) a surfactant comprising at least one kind selected from anionic surfactants and nonionic surfactants, and

(C) contains oil,

Wherein the blending amount of the powdery stabilizer is less than 1% by mass.

(Effects of the Invention)

Example

Hereinafter, the present invention will be described in more detail with reference to Examples, but the present invention is not limited to these Examples at all. The blending amount is expressed as% by mass with respect to the total amount of the composition in which the component is blended unless otherwise specified.

Hair wax was prepared according to the prescriptions listed in Tables 1 to 5 below. The following items (1) to (3) were evaluated according to the following criteria, with the use of hair wax (sample) of each example in a professional panel.

(1) Jointing during application (Stiffness)

Evaluation standard:

A: There is no jam.

B: I feel a little jammed.

C: It feels very hungry.

(2) Airy feeling after treatment

A: It's done very well.

B: It is finished in a polite way.

C: A coarse finish is not obtained

(3) Stickiness after regular pacing

A: It's not sticky at all.

B: It's a little sticky.

C: Sticky

From the results shown in Tables 1 and 2, Examples 1 to 6, in which a predetermined amount (not less than 0.01 mass% and less than 1.5 mass%) of acrylic acid-derived Na-grafted starch was blended, showed a good correction effect (Aerial) regular leg), and did not feel tactile. In particular, in Examples 1, 2, 5, and 6 in which the blending amount of silicic anhydride was suppressed to 0.2 mass% or less, hair was not caught, the hair was able to be aerially stabilized, and tackiness was not felt. In Examples 3 and 4 in which the blending amount of the silicic anhydride exceeded 0.2 mass%, a slight feeling of sticking occurred, but it was acceptable as a product. However, in Comparative Examples 1 and 2 in which 1% by mass or more of anhydrous silicic acid was blended, it was recognized that the coating was difficult to catch.

On the other hand, in Comparative Example 3 which contained anhydrous silicic acid and did not contain acrylic acid Na-grafted starch, it not only caught on the hair but also caused a feeling of sticky feeling. Also, in Comparative Example 4 in which neither anhydrous silicic acid nor sodium acrylate grafted starch was included, a satisfactory finish (airiness after regularization) was not obtained.

In Comparative Examples 5 and 6 in which the blending amount of the acrylic acid Na-grafted starch was 1.5% by mass, even when the blended amount of silicic anhydride was suppressed to 0.2% by mass, sticking occurred after coating or sticking after cleaning. In particular, in Comparative Example 6 in which the blending amount of the liquid oil component was less than 4% by mass, the stickiness after the application at the time of application and the stickiness after the correction were remarkably felt, and the airy feeling was also damaged.

From the results shown in Table 3, it was evaluated that all of the items of Example 1 and Examples 7 to 11 using (B) the anionic and / or nonionic surfactant as the surfactant were excellent. However, Comparative Example 7 using only the amphoteric surfactant (B) as the surfactant did not perform characterization because the emulsion could not be stably emulsified and precipitates were observed.

As shown in Table 4, in the present invention, it was confirmed that even if the types of solid oil fraction and liquid oil fraction were changed, an equivalent effect was obtained.

In Table 5, the characteristics of the samples in which the resin (G component) was further compounded were evaluated. In addition to the above items, the "break power", "appearance", and "thickening" were also evaluated based on the following criteria.

Evaluation Items and Evaluation Criteria

· Power:

A ⁺ : very good

A: Excellent

B: Normal

C: I'm behind.

·Exterior:

+: Good (uniformity without precipitate observed)

-: poor (precipitates are observed)

· Viscosity:

+: Good (the thickening effect by the acrylic acid Na-grafted starch is maintained)

-: Bad (viscosity decrease (reduction) occurred)

From the results shown in Table 5, it was confirmed that when the resin was blended, the basic performance of no jamming at the time of coating, the airiness after stabilization, and the tackiness after stabilization showed no problem and the repulsive force was further improved. However, in view of appearance and thickening effect, a nonionic resin ((VP / methacrylamide / vinylimidazole) copolymer and (vinylpyrrolidone / VA) copolymer) or a cationic resin (polyquaternium-11) No problems occurred in Examples 20 to 22, but in Examples 23 to 27 in which a positive or an anionic resin was blended, inhibition of the thickening effect by precipitation or sodium acrylate grafted starch was observed.

Other formulations of the precondition composition of the present invention are shown below.

There is no stickiness at the time of application or after the treatment, and the airy post-treatment after the treatment. It is also excellent in power, appearance, and viscosity.
