DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a hairdressing composition,
More specifically, the present invention relates to a gel hair styling composition for setting, comprising syrup, a carboxyvinyl polymer and a base.

[0002]

BACKGROUND OF THE INVENTION Carboxyvinyl polymers are used in gel-type hair dressings for setting hair because they exhibit good gelling properties when neutralized with an organic or inorganic base. ing. However, the gel-like hair styling composition containing the carboxyvinyl polymer has a problem that the setting property is not excellent and the properties such as stickiness to hands and hair, finish feeling, gloss and the like are not sufficient.

[0003] In view of the above problems, the present inventors have conducted intensive studies, and as a result, obtained a gel-like hairdressing composition obtained by blending starch syrup, a carboxyvinyl polymer and a specific amount of a base. When applied to the hair,
The present inventors have found that the present invention has excellent set retention properties, and that the hair is finished with a glossy hair that is not sticky to the hand and does not peel off like a dandruff.

[0004] That is, an object of the present invention is to provide an applied hair
An object of the present invention is to provide a gel-like hair styling that gives a glossy hair that is smooth and does not stick to hands or hair, has excellent set retention properties, and does not peel like dandruff.

[0005]

Means for Solving the Problems To achieve the above object, a gel hairdressing composition of the present invention is characterized by containing starch syrup, a carboxyvinyl polymer, and a base.

In the present invention, by using syrup and a carboxyvinyl polymer and a base in combination, the drawbacks of the carboxyvinyl polymer gel, that is, persistent stickiness to hands and hair, are generally remarkably suppressed. Then, the set hair is not sticky, has excellent set holding properties, does not peel like dandruff, and gives a glossy finish.

[0007] In the present invention, starch syrup itself is known, and can be obtained by adding water to starch, heating it to form a glue, adding a dilute acid (mineral acid or oxalic acid) or an enzyme amylase, and hydrolyzing. it can. In addition, starch syrup consists of dextrin, maltose, and glucose, and the composition ratio varies depending on hydrolysis conditions.

[0008] In the present invention, a particularly preferred starch syrup is an enzyme-saccharified starch syrup, and its composition is dextrin 20 to 25.
%, Maltose 40 to 60%, and glucose 1 to 5%. The compounding amount is about 0.05 to 10% by weight of the whole composition.

The carboxyvinyl polymer used in the present invention is known per se, and is used as a gelling component of gel cosmetics. Carboxyvinyl polymers are described in B.C. F. G
oodrich Chemical Co. It has a molecular weight of 1,000,000 to 3,
000,000 and various grades with different gelling strengths. As a specific example,
For example, Goodrich Chemical Ca

3, Hibiswako 104 and Hibiswako 105. Depending on the desired viscosity, the viscosity can be determined by appropriately combining them.

[0010] The compounding amount is suitably 0.05 to 5% by weight. The base according to the present invention is used for neutralizing a carboxyvinyl polymer, and one or two of triethanolamine, diisopropanolamine, aminomethylpropane, aminomethylpropanediol, sodium hydroxide, and potassium hydroxide are used. And can be adjusted to the desired viscosity.

[0011] In addition to the starch syrup, the carboxyvinyl polymer and the base, a small amount of a nonionic surfactant, a fragrance or the like can be added to the gel hair styling composition of the present invention. As the carrier, it is preferable to use water or an aqueous carrier composed of water and a lower alcohol.

[0012]

The present invention will be described below by way of examples. Numerical values in the formulations of Examples and the like indicate weight% of each component. The evaluation method employed in each example is as follows.

(Practical test) Hairdressing was carried out by 20 subjects using each gel-like hairdressing composition and a control sample. Thereafter, the subject himself performed a sensory evaluation on the test items in Table 1.

[0014]

[Table 1]

Example 1 Gel hair styling compositions of Example 1 and a control were obtained according to the compositions shown in Table 2 by the following preparation method.

[0016]

[Table 2]

Preparation method: Water syrup, and a carboxyvinyl polymer dispersion previously swollen in a part of water are added and mixed with stirring. Next, a liquid in which polyoxyethylene hydrogenated castor oil, diisopropanolamine, and a fragrance were dissolved in ethyl alcohol was added, and the mixture was uniformly stirred and mixed with a homomixer to prepare a transparent gel-like hairdressing composition.

[0018] The gel-like hair styling thus prepared contains 40
The stability when stored at ℃ for 3 months was good. Practical test evaluation was performed using this gel-like hair styling in comparison with a control, and the results are shown in Table 3.

[0019]

[Table 3]

Example 2 The gel hair styling compositions of Example 2 and the control were obtained according to the compositions shown in Table 4 by the following preparation method.

[0021]

[Table 4]

Preparation method: Water syrup, glycerin, and two kinds of carboxyvinyl polymer dispersions swollen in a part of water are added and mixed with stirring. Next, a liquid in which polyoxyethylene hydrogenated castor oil, triethanolamine, polyvinylpyrrolidone and a fragrance were dissolved in ethyl alcohol was added, and the mixture was uniformly stirred and mixed with a homomixer to prepare a transparent gel-like hairdressing composition.

[0023] The gel-like hair styling thus prepared is 40
The stability when stored at ℃ for 3 months was good. Practical test evaluation was performed using this gel hairdressing composition in comparison with the control. The results are shown in Table 5.

[0024]

[Table 5]

Example 3 The gel hairdressing composition of Example 3 was obtained according to the composition shown in Table 6 by the following preparation method.

[0026]

[Table 6]

Preparation method: Water syrup and two kinds of carboxyvinyl polymer dispersions swollen in a part of water are added and mixed with stirring. Next, a solution in which polyoxyethylene hydrogenated castor oil, diisopropanolamine, and a fragrance were dissolved in ethyl alcohol was added, and liquid paraffin was further added. The mixture was uniformly stirred and mixed with a homomixer to prepare a gel-like hair dressing.

The gel-like hair styling prepared in this manner is 40
The stability when stored at ℃ for 3 months was good. In addition, the applied hair was smooth and did not stick to the hands, was excellent in set retention, did not peel off like dandruff, and could be finished with glossy hair.

[0029]

As described above, when applied to hair, the present invention provides a gel that gives a lustrous hair that is smooth, does not stick to hands, has excellent set retention, does not peel like dandruff, and does not peel off. It is clear that hair styling is provided.
