Description

  The present invention relates to a hair cosmetic.

  2. Description of the Related Art Conventionally, hair cosmetics have been used that exhibit the function of a hair styling agent (hair styling power) for conditioning hair and have a characteristic that makes certain white hair inconspicuous. As such hair cosmetics, for example, those in which a component having a high property of imparting gloss (luster) to hair, such as a polyhydric alcohol, a liquid oil, and a set polymer, are known (for example, Patent Document 1). 2). Such a hair cosmetic employs a technique for making gray hair inconspicuous by combining the light reflectivity of white hair and black hair with the gloss after styling.

The hair cosmetic composition of the present invention can be used in combination with the component (B) and the component (C) to exhibit the advantages of both, and is excellent in both the ability to stand up the hair and the property of making gray hair inconspicuous. .

  In addition to these, by blending polyethylene glycol [component (D)] having a number average molecular weight of 300 or more and 8000 or less, the effect of imparting the power and luster to raising hair is further improved, and carboxyvinyl polymer and / Or by adding an alkyl-modified carboxyvinyl polymer [component (E)] to increase tackiness while suppressing stickiness to improve handling, diglycerin, dipropylene glycol, 1,3-butylene glycol, glycerin And the effect which provides glossiness is further improved by mix | blending 1 or more polyhydric alcohol [component (F)] selected from the group which consists of propylene glycol. Further, one or more colors selected from the group consisting of blue legal dye, black legal dye, purple legal dye, green legal dye, red rose, ultramarine blue, bitumen, chromium oxide, chromium hydroxide, lithium cobalt titanate, and manganese violet. By blending the agent [component (G)], in addition to matching the light reflectivity of white hair and black hair by gloss, the effect of complementing white hair with yellowing derived from the yellow pigment in the hair makes the white hair stand out The effect of eliminating is even better. Such a hair cosmetic that imparts such a high gloss as to make gray hair inconspicuous and is excellent in the ability to raise hair has not been known so far, and has been technically difficult, This is achieved for the first time by the present invention.

  Hereinafter, the present invention will be described in more detail based on examples. However, the present invention is not limited to these examples. In addition, the compounding amount described in the table is the compounding amount of each component (that is, the compounding amount of the active ingredient in each raw material, so-called pure content), and is represented by “mass%” unless otherwise specified.

Examples 1-7, Comparative Examples 1-5
Using the respective components (components (A) to (I) and other components) described in the table, hair cosmetics of Examples and Comparative Examples were prepared by a conventional method.

(Evaluation)
Each hair cosmetic obtained in Examples and Comparative Examples was evaluated as follows. The evaluation results are shown in the table.

[Test Example 1: Ability to raise hair]
About 0.5 g of each hair cosmetic obtained in Examples and Comparative Examples was taken in the palm, spread on the palm, and applied to a wig (trade name “Stuff Cut Wig” manufactured by Beaulux Co., Ltd.). Application was performed on either the left or right half of the wig. Thereafter, the hair was trimmed with a hand comb, and the hair at the top of the wig was raised from the root upward and gathered. And the "power to raise hair" was determined according to the following criteria from the hair-styling state at the top of the wig.
<Criteria for the ability to raise hair>
○ (good): The hair could be trimmed to raise the hair.
X (defect): The hair could not be raised.

[Test Example 2: Characteristics that make gray hair inconspicuous]
About 0.2 g of each hair cosmetic obtained in Examples and Comparative Examples was applied to a 10% white hair mixed hair bundle (product name “BM-MIX-K10” manufactured by Beaulux Co., Ltd.). Thereafter, the degree of conspicuousness of the hair bundle and gray hair before application was visually evaluated.
<Criteria for the degree of conspicuous gray hair>
○ (good): The amount of gray hair appears to be clearly smaller than that of the uncoated hair bundle.
Δ (insufficient): The amount of gray hair appears to be slightly smaller than the unapplied hair bundle.
X (defect): Compared with unapplied hair bundle, the amount of gray hair looks the same.

  The hair cosmetics (Examples) of the present invention were excellent in the ability to stand up hair and the property of making gray hair inconspicuous. On the other hand, when the component (B) was not included (Comparative Example 1), the component (F) was not included (Comparative Example 4), and the component (G) was not included (Comparative Example 5), white hair was conspicuous. It was inferior in the characteristic to lose. Further, when the component (C) was not included (Comparative Example 2) and when the component (D) was not included (Comparative Example 3), the ability to raise hair was inferior.
