Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair cosmetic composition, which is not sticky to the hair, provides an excellent gloss and wet feeling to the hair, and imparts a smooth feel to the hair while having a good set-holding power. Regarding cosmetics.

[0002]

2. Description of the Related Art Conventionally, hair cosmetics have been used by solubilizing, emulsifying or dissolving oil components such as silicone oils, ester oils and hydrocarbon oils for the purpose of imparting gloss and smoothness to hair. . In particular, silicone oil has been widely used in recent years because it has a low surface tension, is excellent in conformity to hair, and has good gloss. However, the oil represented by silicone oil has a limitation that the oil has a limit, and when it is used in a large amount or the consumer uses it for a long time, it has a drawback that the squeaky feeling of the hair is increased and the hair becomes greasy. Also, in order to give the hair a feeling of getting wet (wet feeling),
Moisturizers such as propylene glycol have been used,
When it was mixed in a large amount, it had the drawback of being sticky and inferior in sustainability. On the other hand, although a cationic surfactant is often used for the purpose of imparting smoothness, it has a drawback that it does not give a desired gloss and that it is unfavorable from the viewpoint of safety when blended in a large amount. For the purpose of setting hair, a polyvinylpyrrolidone-based polymer as a high molecular compound,
An acidic polyvinyl ether polymer, an acidic acrylic polymer, a cationic polymer, or the like is blended. However, although these polymer compounds are excellent in fixing or setting the hair, they are not satisfactory in gloss and smoothness. Further, a combination of an amino-modified silicone and a cationic surfactant has been proposed, which gives smoothness to hair, but is sticky, and the coating film thereof has poor transparency.

Means for Solving the Problems In order to solve the above-mentioned technical problems, the present inventors provide hair with a non-greasy feeling, an excellent luster and a wet feeling, and a smooth feeling, and As a result of intensive studies to obtain a hair cosmetic having good set-holding power, a specific amphoteric polymer compound, a moisturizer selected from glycerin, diglycerin, and polyglycerin, liquid paraffin, liquid isoparaffin, and squalane. It becomes possible to mix a large amount of each component with a hydrocarbon oil selected from squalene at the same time. Also, it gives the hair a non-sticky feeling, an excellent gloss and wet feeling, and a smooth feel. Moreover, they have found that a hair cosmetic having good set-holding power can be obtained, and have completed the present invention.

That is, the present invention comprises 0.3 to 10.0% by weight of one or more amphoteric polymer compounds and one or more of moisturizing agents selected from glycerin, diglycerin and polyglycerin. 8.0-20% by weight
And 10 to 20% by weight of one or two or more hydrocarbon oils selected from liquid paraffin, liquid isoparaffin, squalane and squalene.

The structure of the present invention will be described in detail below. The amphoteric polymer compound used in the present invention is a soluble or dispersible polymer in a product, and a resin represented by the following general formula is particularly preferable, and in the present invention, one or two of them are used. The above can be selected and used. General formula:

[Chemical 1] (N: m = 90: 10 to 50:50, molecular weight is 50,0
It is in the range of 00 to 500,000. R1 and R6 are hydrogen atoms or methyl groups, R3 and R4 are alkyl groups having 1 to 4 carbon atoms, R2 and R5 are alkylene groups having 1 to 4 carbon atoms, and R7 is 1 to 24 carbon atoms. A saturated or unsaturated alkyl group having an atom, A is an oxygen atom or an NH group, or none. )

The amphoteric polymer is a polymer which is soluble or dispersible in the combined solvent system if any solvent such as ethanol is present in the product. Among these amphoteric polymers, n: m = 90: 10 to 70:30 and R7 is 12
Particularly preferred are saturated or unsaturated alkyl groups having -24 carbon atoms. The content of the amphoteric polymer compound used in the present invention is 0.3 to 10.0% by weight, preferably 3.0 to 5.0% by weight. If the compounding amount is less than 3.0% by weight, the amphoteric polymer compound cannot exert the effect as a setting agent, and if it exceeds 10.0% by weight, a sticky feeling may remain.

The glycerin, diglycerin and polyglycerin used in the present invention are not particularly limited, and any commercially available products can be used, and they may be natural products or synthetic products. In the present invention, one kind or two or more kinds selected from these can be used.

The content of these is 8.0 to 20.
It is 0% by weight, preferably 10.0 to 15.0% by weight. When the content is less than 8.0% by weight, the sufficient effect required in the present invention cannot be obtained, and when it exceeds 20.0% by weight, a sticky feeling may remain.

The hydrocarbon oil used in the present invention is liquid paraffin, liquid isoparaffin, squalane, and squalene, which may be natural products or synthetic products, and any one or two or more of them may be selected and used. be able to. Further, the content of hydrocarbon oil in the present invention,
It is 10.0 to 20.0% by weight, preferably 10.
It is 0 to 15.0% by weight. If the blending amount is less than 10.0% by weight, the sufficient effect required in the present invention cannot be obtained, and 2
If it exceeds 0.0% by weight, a sticky feeling may remain.

The hair cosmetic composition of the present invention contains, in addition to the above essential components, a vasodilator such as capronium chloride and vitamin A.
, Vitamins such as vitamins B, vitamins C, vitamins D and vitamins E may be mixed. Furthermore, components generally used in hair cosmetics can be blended within a quantitative and qualitative range that does not impair the effects of the present invention. For example, amphoteric surfactant, cationic surfactant, anionic surfactant, nonionic surfactant,
