Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic for hair, and more particularly to a cosmetic for hair having a gel-like or cream-like property which is less sticky and can be easily removed with a finger.

[0002]

2. Description of the Related Art Conventionally, in order to prepare a highly viscous cosmetic material to be put in a jar, it is necessary to use an emulsifier to form a cream or a polymer such as polyacrylic acid. It is common to use a gel. However, a cream using an emulsifier is suitable for the skin, but the viscosity of the hair cosmetic is limited to about 10 Pa · s from the point of stickiness and the like, and in a jar bottle, it flows out when the container is tilted. There was a disadvantage. Further, a gel using a polymer such as polyacrylic acid has a problem in that although it is easy to suppress stickiness and increase the viscosity, it is difficult to collapse structurally and cannot be scraped off with a finger.

[0003] In order to solve these problems, an example in which a natural polymer and an acrylic acid-based polymer are combined (Japanese Patent Laid-Open No.
2-263111 and JP-A-4-230317), however, when the viscosity is increased, stickiness derived from a polymer is developed, and the use feeling and the palatability are not sufficient. In addition, an example is disclosed in which a glycerin derivative is used to increase the viscosity in order to overcome stickiness (Japanese Patent Application Laid-Open No. 5-170621).
However, when the viscosity is increased, there is a problem that it is difficult to scoop with a finger.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned drawbacks of the conventional hair cosmetics, and has low stickiness at the time of use and hair having a gel-like or cream-like property which is easy to scoop with fingers. The purpose is to provide cosmetics for cosmetics.

[0005]

Means for Solving the Problems and Embodiments of the Invention The present inventors have made intensive studies to achieve the above object, and as a result, have found that a polyglycerin derivative, a natural polymer and an acrylic acid-based polymer can be used together. The present inventors have found that the three components act synergistically to provide a hair cosmetic composition that has less stickiness and is easy to scoop with a finger, and has accomplished the present invention.

Hereinafter, the present invention will be described in more detail.
The hair cosmetic composition of the present invention is a combination of a polyglycerin derivative, a natural polymer, and an acrylic acid polymer, whereby a hair cosmetic composition with less stickiness and easy to scoop can be obtained. The polyglycerin derivative used in the present invention has a polymerization degree of glycerin of 2 to 16, for example, diglycerin, hexaglycerin, polyglycerin such as decaglycerin, lauric acid, tridecyl acid, myristic acid, pentadecyl acid, palmitic acid, heptadecyl acid. , Stearic acid, isostearic acid, nonadecanoic acid,
Examples thereof include fatty acids having 12 to 22 carbon atoms such as arachiic acid and behenic acid, which are ester-bonded, and the degree of ester substitution is not particularly limited. These polyglycerin derivatives may be used alone or in combination of two or more. Among them, fatty acids having a polymerization degree of glycerin of 4 to 14 and ester-bonded fatty acids having 16 to 22 carbon atoms are preferable. The compounding amount of the polyglycerin derivative is 0.1% based on the whole hair cosmetic.
1 to 20% by weight, particularly 1 to 15% by weight, is suitable. If the amount is too small, the desired effect may not be sufficiently exhibited, and if it is too large, the touch may be unfavorable.

Next, the natural polymer used in the present invention is selected from xanthan gum, guar gum, karaya gum, quince seed gum and carrageenan, and may be used alone or in combination of two or more. The blending amount of these natural polymers is preferably from 0.01 to 2% by mass, particularly preferably from 0.1 to 1% by mass, based on the whole hair cosmetic. If the amount is too small, the desired effect may not be sufficiently exhibited, and if it is too large, stickiness may occur.

Further, as the acrylic acid-based polymer used in the present invention, a carboxyvinyl polymer is preferably used, and an alkyl-modified polymer may be used. The compounding amount of these acrylic acid-based polymers is 0.01 to
2% by weight, especially 0.1-1% by weight, is preferred. If the amount is too small, the desired effect may not be sufficiently exhibited. If the amount is too large, the viscosity may be high and it may be difficult to scoop up by hand.

[0009] The hair cosmetic of the present invention, besides the above-mentioned essential components, may be any one within a range that does not impair the object of the present invention.
Surfactants, polyhydric alcohols, silicones and their derivatives, plant extracts, protein hydrolysates and their derivatives, fragrances, dyes, preservatives, ultraviolet absorbers, pH adjusters, solvents such as ethanol and water that can be used as cosmetics And the like. These components may be used alone or in combination of two or more. There is no particular limitation on the method of addition, and it can be appropriately added at an appropriate stage in the preparation of the hair cosmetic.

[0010]

The hair cosmetic of the present invention can be used as a cosmetic for hair, for example, prepared in various dosage forms such as cream, gel and wax.

[0011]

EXAMPLES Hereinafter, the present invention will be described more specifically with reference to Examples and Comparative Examples, but the present invention is not limited to the following Examples. In addition, the compounding amount in each example is all the mass%. [Examples and Comparative Examples] Gel cosmetics for hair having the composition shown in Table 1 were produced, and the feel during use (easiness of scooping with a finger, non-stickiness) was evaluated by the following method. Table 1 shows the results. Evaluation method : -Evaluation of feeling of use Twenty female panelists used each hair cosmetic after shampooing and rinsing, and the ease of scooping with a finger and the absence of stickiness were evaluated according to the following criteria. ：: 16 or more out of 20 responded as good ○: 10 to 15 out of 20 responded as good △: 4 to 9 out of 20 responded as good ×: answered as good Less than 3 out of 20
