Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is excellent in the effect of suppressing the generation of split and broken hair on hair damaged or weakened by chemical treatments such as perm, bleach, hair color, etc. The present invention relates to a hair cosmetic which gives a good feel without stickiness.

[0002]

2. Description of the Related Art Hair is heavily damaged by daily hair care and hair makeup activities. Especially in the hair washing, the sebum and hair constituent proteins of the hair are eluted by the surfactant which is the main component, and the hair becomes rough or rough,
Furthermore, it is known that the damage is visually and tactilely sensed such as extremely loss of gloss. In recent years, the use of cold perm, hair color, hair bleach, etc. has increased due to the rise in fashionable consciousness, and chemical treatment with drugs has promoted the dissolution and structural change of hair constituent proteins, which has spurred damage. . In addition, hand dryers used as means for drying wet hair are also a major cause of hair damage,
This causes structural change due to heat, resulting in a decrease in strength and a decrease in water retention capacity.
Further, physical stimulation by brushing results in promotion of cuticle peeling, tearing, and cutting of hair on the hair surface.

Conventionally, as a means for protecting hair from such many causes of damage, there is known a method of penetrating and replenishing hair with components similar to hair, such as collagen derivatives and keratin derivatives. JP-A-57-8810
9, JP-A-2-53712, JP-A-4-60083
No.). In addition, hair cosmetics containing various polymer compounds, silicone derivatives, and the like are also known in order to suppress cuticle peeling of the hair surface and to smooth the surface to prevent damage due to friction.

[0004] However, these are merely tactile or visual enhancements, do not really strengthen or repair damaged hair, and their effects are not sufficiently satisfactory.

[0005]

DISCLOSURE OF THE INVENTION The present invention overcomes the drawbacks of the conventional hair cosmetics and changes the hair structure by shampooing or chemical treatment, so that damaged hair is treated like healthy hair. In addition to strengthening and restoring the hair, it also provides an excellent hair cosmetic that suppresses feathering / peeling, cut-off, and hair loss of the cuticle even under physical force such as brushing, and has less stickiness during use.

Next, the present invention will be described in more detail by way of examples. In addition, the amount of each component is% by weight.

Examples 1 and 2 and Comparative Examples 1 to 5 First, evaluation methods and evaluation criteria for hair cosmetics will be described. <Evaluation Method of Damage Prevention Effect> As described above, the hair is weakened not only on the surface of the hair but also on the internal structure due to the elution of the protein constituting the hair and the structural change due to the treatment with the hair such as washing and cold perming. This further causes cuts and tears due to thermal and physical forces such as a hand dryer, blow and brushing performed for the purpose of drying and setting. The present inventors have strengthened and repaired damaged hair,
The evaluation method of the effect of making it difficult to generate torn hair was examined. The brushing treatment under hot air similar to the actual hair makeup operation had poor reproducibility of the effect, and was unsuitable as an evaluation method. Therefore, as a result of repeated sharp duels in the evaluation method, we established a simple and highly reproducible evaluation method that gives the hair a strong physical force called freeze-drying and observes the state after the treatment with a scanning electron microscope. did. That is,
As shown in Table 1, cracks are small in healthy hair even when freeze-dried, but many cracks can be confirmed in hair that has been structurally weakened by treatment with a commercial cold perm agent. The method was found to be appropriate as a method for evaluating the effect of strengthening and repairing damaged hair. Table 1 shows values calculated as crack occurrence rates with respect to the number of treatments by the following equation.
