Description

[Detailed Description of the Invention] The present invention has excellent effects in preventing hair damage such as heat damage to hair and mechanical effects such as brushing, split ends, and cut hair, and has a spraying effect. Alternatively, the present invention relates to an aerosol-type hair cosmetic that can be used as a foam-generating aerosol-type hair cosmetic.

In recent years, both women and men are using heat tools such as hand dryers and curl dryers to dry their hair after washing and set their hairstyles. Hair care behaviors such as brushing hair with a brush are increasing. On the other hand, there is a tendency for consumers to dislike oily and sticky hair cosmetics, and the usage rate of hair creams, hair oils, etc. among women is decreasing, and the usage rate of hair liquids, hair pomades, etc. is decreasing among men. ing. For this reason, recently.

Dry hair caused by using heat equipment.

Hair damage such as split ends and cut hair due to mechanical effects from brushes, etc. is increasing, and the degree of hair damage is increasing due to hair diameters that have been chemically processed such as perms and hair coloring, which has been on the rise in recent years. There is a need for measures to prevent or reduce 1-mome damage.

Therefore, JP-A-62-8406 discloses an aerosol-type hair cosmetic that is less sticky and feels good when used on hair, and is intended to prevent hair damage. is a cationic surfactant,
In addition to those using polyoxyalkylene glycol, those containing chitin/chitosan have been proposed in Japanese Patent Publication Nos. 31324/1982, 8701/1987, and 190502/1986.

In addition, hair cosmetics containing herbal medicines (plant extracts) that have the effect of preventing hair damage are also available, such as those containing herbal medicines such as Orchidium orientalis (Japanese Unexamined Patent Publication No. 101412/1982), and herbal medicines. , containing tannic acid (Japanese Patent Application Laid-Open No. 61-3
No. 0504 (11l).

Contains loquat extract and polyhydric alcohol (Unexamined Japanese Patent Publication No. 6
1-106176) and the like are also known.

However, these hair cosmetics are not sufficiently effective in preventing hair damage, and in particular, hair that is easily damaged by chemical treatments such as perms may become dry due to heat damage, split ends due to brushing, etc. It has been difficult to prevent or reduce the occurrence of hair breakage.

Therefore, it has been desired to develop an aerosol-type hair cosmetic that is more effective in preventing hair damage.

The present invention has been made in view of the above circumstances, and is intended to address problems such as hair that becomes dry due to heat damage after chemical treatments such as perm and hair coloring, or hair that suffers from split ends or cut hair due to mechanical effects such as brushes. It is an object of the present invention to provide an aerosol-type hair cosmetic that is excellent in the effect of preventing hair damage and can effectively prevent or reduce hair damage.

In order to achieve the above object, the inventors of the present invention have made intensive studies and found that two or more species selected from arnica, calendula, japonica, horsetail, chamomile, japonica, salvia, malva, and yarrow. A plant solvent extract, a cationic polymer compound, and a cationic surfactant.

When aerosol hair cosmetics containing polyhydric alcohols or their derivatives are used on hair that has undergone chemical treatments such as perming or hair coloring, the hair may become dry even after brushing with a heat tool such as a hair dryer. In addition, even if the hair is repeatedly brushed with a brush after drying, the incidence of split ends and cut hair is very low. The present inventors have discovered that the present invention is superior and have come up with the present invention.

Therefore, one aspect of the present invention is.

(1) Arnica, Calendula, Bodaiju.

(2) a cationic polymer compound; (3) a cationic surfactant; (4) a cationic surfactant; To provide an aerosol type hair cosmetic characterized by being blended with a hydrolic alcohol or a derivative thereof.

The present invention will be explained in more detail below.

The solvent extracts of plants that are the first essential ingredient of the present invention are arnica, calendula, and bodega.

It is extracted with a solvent from two or more plants selected from horsetail, chamomile, deadweed, salvia, malva, and yarrow, and this extract contains tannins, flavonoids, terpenoids, amino acids, etc. as active ingredients.

Here, the above-mentioned plant may be used in a part such as the flower part or the eastern part, or the whole plant may be used as necessary.
It is preferable to use dried products of these.

In addition, there are no particular restrictions on the solvent extraction method for plants, and dry plants can be used as is or ground, and then water can be added.

Extraction can be carried out using conventional methods and conditions by adding a solvent such as a lower alcohol such as ethanol, a polyhydric alcohol, or a mixture thereof, but especially propylene glycol,
A method of extraction using a mixed solvent of a polyhydric alcohol such as glycerin or 1,3-butylene gellicol and water and immersing the dried plant material in the mixed solvent at room temperature for about two weeks can be suitably employed. Note that the mixing ratio of polyhydric alcohol and water is preferably 1:9 to 9:1 as a weight ratio.

In this case, the solvent extract of the plant includes one or more selected from the group of arnica, sagebrush, yarrow, and calendula among the above nine types of plants, and one or more selected from the group of horsetail, horsetail, salvia, malva, and chamomile. It is preferable to use one or more selected types, and in particular, the proportion of plants from both groups is 1=9 to 9:1 by weight.
More preferably, solvent extracts of plants such as these can be used. In this case, either a mixture of solvent extracts obtained by solvent extraction of each dried plant material by the above method is used, or a mixture of the dried plants of the plants in the proportions mentioned above is extracted with a normal solvent. use.

Further, the amount of the solvent extract of the above plant is not particularly limited, but it is preferably 0.001 to 10% (wt%, same hereinafter), particularly 0.05 to 5% of the total cosmetic composition.
If the blending amount is less than 0.001%, sufficient hair damage prevention effect will not be obtained.
