Description

  The present invention relates to a hair cosmetic composition suitable for the care of hair, particularly so-called damaged hair, in which damage due to chemical treatment or sunlight has accumulated.

  Conventionally, many hair cosmetic compositions for caring for hair damaged by various causes are known, and hair treatment agents that are used after shampooing and washing off are widely used. This type of hair treatment agent is generally a so-called oil-in-water emulsified cream type in which a continuous phase gel composed of a cationic surfactant and a higher alcohol and water is formed, and silicone or vegetable oil is emulsified. (Patent Document 1).

On the other hand, so-called out-bath type hair treatment agents, which are applied without being washed away, are also popular in recent years. As a feature of this type, there is an aspect that the active ingredient is easily penetrated into the hair because it is not washed away, the actual sensitivity gradually increases by continuing to use, and an easy-to-use aspect that can be used anytime and anywhere when the damage is anxious. Outbass-type hair treatment agents are premised on not washing out, so the amount of oil in the composition is relatively low compared to washing-up type hair treatment agents, but the basic prescription skeleton is almost the same The so-called oil-in-water emulsified cream type is the mainstream. Apart from this, the aerosol spray type hair cosmetic composition, formerly called glossy spray and oil spray, has been improved in formulation to bring out the treatment effect, or derived oily oil type. Many hair cosmetic compositions have been proposed in recent years. (Patent Documents 2 to 6).

  However, the hair cosmetic compositions as disclosed in Patent Documents 1 and 2 are oil-in-water creams, and the main component in the composition is water. For this reason, when using it for dry hair, it permeates the application site too quickly, and there is a drawback that it is difficult to extend to the whole hair. As a matter of course, it is unsatisfactory for the user, and therefore, it is overlaid, resulting in a large amount of use. For this reason, problems such as increase in consumption and occurrence of stickiness due to excessive application occur. After all, although the out-bath type treatment agent was originally characterized by being easy to use, there is a problem that it lacks convenience, for example, it is necessary to dry it after drying.

On the other hand, the hair cosmetic compositions described in Patent Documents 3 and 4 are aerosol spray type hair cosmetic compositions containing little or almost no moisture. However, these aerosol spray-type hair cosmetic compositions can be applied uniformly over the entire hair surface, but cannot be sufficiently penetrated into the vicinity of the root, or may be scattered to the surroundings. The problem is not solved.

Patent Documents 5 and 6 are oily liquid hair cosmetic compositions corresponding to the stock solution part of the aerosol spray type hair cosmetic composition. A small amount of cosmetics is taken into the palm of the hand and soaked into the damaged part. To apply. For this reason, problems such as penetration to the vicinity of the root and scattering to the surroundings have been solved. However, the operation of taking a small amount of the liquid hair cosmetic composition on the palm and extending it to the hand is not easy for an unaccustomed person such as the liquid dripping from the hand. In addition, since it is premised on a small amount of use, it is difficult to uniformly apply to the entire dry hair. After all, in order to avoid these problems, it is necessary to recommend a method of pre-wetting the hair with water and applying the hair cosmetic composition thereon, and there are still problems in convenience. Furthermore, the hair cosmetic compositions described in Patent Documents 3 to 6 are all liquid, and the actual sensitivity and sustainability of the damage care effect are not sufficient.

  The present invention has been made paying attention to the problems existing in the prior art as described above. Its purpose is based on the synergistic action between the blended ingredients, with the convenience that can be applied uniformly and easily to the whole hair, and the excellent damage hair care effect with high actual sensitivity and durability. A novel hair cosmetic composition is provided.
