Description

  The present invention relates to a hair cosmetic.

  In recent years, in addition to chemical treatments such as hair coloring and perm, hair damage caused by hair sets using heat such as hair irons and hair dryers, which has become a habit mainly for young women, has become serious. It is known that hair damage is accompanied by loss of 18-MEA (18-methyleicosanoic acid), which is a fatty acid covering the hair surface, and causes an increase in surface friction as the hair surface becomes hydrophilic. Therefore, in order to return the hair to a smooth feeling before the treatment, a hair cosmetic that is a combination of a tertiary amine compound and a higher alcohol is used as a conditioning agent.

  For example, in Patent Document 1 (Japanese Patent Application Laid-Open No. 2004-67534), a hair cosmetic that is a combination of a specific tertiary amine compound and a higher alcohol is mixed with a specific organic solvent under an acidic pH of 2-6. By containing it, it excels in the effect of repairing or suppressing the cavities generated in the hair during coloring, dryer drying, etc., and the smoothness, softness and smoothness of smoothness from application to rinsing It is described that it is excellent in the effect of giving.

  In Patent Document 2 (Japanese Patent Laid-Open No. 2006-290796), in a hair cosmetic that combines an amidoamine and a higher alcohol, a specific amount of an organic acid is added to an amidoamine having a hydrocarbon chain length of a specific length. By using it, while repairing and preventing hair damage due to coloring and drying of the hair, etc., it gives a sufficiently smooth coat feeling during the rinsing after applying to the hair and rinsing, and even the damaged hair is smooth and organized. It is described that it is possible to give a feeling of finish with.

  Patent Document 3 (Japanese Patent Application Laid-Open No. 2006-265205) discloses a hair conditioning composition of a type that does not wash away, which is a combination of M3T (methyltrimethicone), which is a volatile silicone, a non-volatile silicone derivative, and a cationic surfactant. It is disclosed. Patent Document 3 describes that this hair conditioning composition is fast in drying after being applied to dry hair and is excellent in the effect of imparting a smooth feel and flexibility to the hair.

  On the other hand, hair that has become hydrophilic due to damage becomes difficult to dry after shampooing, and it takes a long time to dry with a dryer or the like, which is a physical burden on consumers. In addition, damaged hair that has become wet and soft is easily entangled, and the traps that occur during drying of the dryer add to the accumulation of further damage and the psychological burden on the consumer.

  However, in the techniques described in Patent Documents 1 and 2, the oil agent remaining on the hair gives a smooth smooth feeling and a sufficiently smooth coat feeling, and further gives a smooth and cohesive finish to damaged hair. However, there is no description about wet hair drying quickly.

  Patent Document 3 describes that drying after applying a hair conditioning composition to hair is fast. The hair conditioning composition specifically disclosed in the document is only a type that does not wash away, and the effect of “fast drying after application” described in the document is that the hair conditioning composition itself dries quickly. is there. Therefore, this document does not suggest at all the speed of drying after using a type of hair cosmetic that itself is washed away after application to the hair.

  Therefore, the present invention can be applied to the hair after washing the shampoo and then washed away so that the wet hair is scattered without tangling, and the hair after drying does not become sticky, and the hair feels smooth. Provided is a hair cosmetic that can achieve both a moist feeling.

  According to the study of the present inventor, “hair scattering” is important as a factor for increasing the drying speed of the hair after washing. That is, when the hair is dispersed, the contact area between the hair and the towel increases when the towel is dried, and the moisture of the hair is quickly absorbed by the towel. In addition, not only when drying a dryer, but also when drying naturally, the area of contact with air increases and the moisture of the hair evaporates quickly.

  And in the hair cosmetics of the type to be washed away after shampooing such as hair rinse, hair conditioner, etc., the present inventor is a volatile silicone methyltrimethicone having a stickiness due to adhering components on the hair while loosening the hair. The present inventors have found that wet hair after treatment is very easy to disperse, hair entanglement is less, and the drying speed can be dramatically improved.

including.

In the hair cosmetic obtained by the above procedure, the tertiary amine compound of component (A) or a salt thereof efficiently remains in the hair, and the slipperiness is improved by the silicone of component (C).
In the hair cosmetic composition of the present embodiment, the components (A) to (D) and water are used in combination, and the components (A) to (D) are used in a specific ratio, so that hair wet with water can be obtained. Tangles between towel drying and drying can be suppressed, and the dispersion between hairs can be promoted and the drying time can be shortened.

Here, in the hair cosmetics such as a conditioner, by blending the conditioning component, the lubricity of the hair can be improved, so that the effect of suppressing the crossing and tangling of the hair and preventing the hair from becoming entangled is improved. . On the other hand, the addition of the conditioning component improves the adhesiveness between the hairs, so that the hairs are prevented from separating and becoming separated, and the ease of drying of the hairs is suppressed.
That is, since the lubricating component blended in the hair cosmetic has adhesiveness, there was a trade-off relationship between imparting the lubricating property to the hair by the lubricating component and suppressing the adhesiveness between the hairs.

On the other hand, according to this embodiment, it is possible to achieve both imparting lubricity to hair and imparting non-tackiness. More specifically, by combining the components (A), (B) and (D) so that the hairs are easily separated from each other, the component (C) is kept to a minimum in the hair, so that a towel can be dried or a dryer, etc. In addition to being able to effectively suppress entanglement of wet hair such as during drying, the adhesion between the hairs can be suitably suppressed to improve the dispersibility between the hairs. For this reason, it becomes possible to obtain the quick-drying property and entanglement prevention effect which can be realized by the user, for example.
In addition, by using the hair cosmetic composition of the present embodiment, it is possible to achieve both a smooth and moist feeling of hair while suppressing the stickiness of the hair after drying.

  Further, the hair cosmetic composition of the present embodiment is used after being applied to the hair, and is used in the bathroom such as a hair rinse, a hair conditioner, a hair treatment, and a hair pack.

  In order to perform hair conditioning using the hair cosmetic composition of the present embodiment, the hair cosmetic composition of the present embodiment may be applied to the hair and then washed off with water. Thus, the hair bundle is easily separated during towel drying after rinsing, wet hair can be dried in a short time, and a dry and moist feeling can be imparted to the hair after drying.

  As mentioned above, although embodiment of this invention was described, these are illustrations of this invention and various structures other than the above are also employable.
