2. Description of the Related Art Conventionally, hair cosmetics include various hair care agents such as collagen, keratin protein, higher alcohols, ester oil, liquid paraffin, etc. for the purpose of preventing or suppressing hair damage due to chemical treatment such as perm. Has been applied to

[0003]

However, protein components such as collagen and keratin protein have some effects in preventing damage due to chemical treatment of hair, but the effects are not sufficiently satisfactory. Also,
The oil component has a certain effect in preventing hair damage, such as reducing the surface friction of hair, and gives a temporary good feeling of use, but lacks a sustained action on hair that has already been damaged In fact, satisfactory treatment effects have not been obtained.

[0004] Further, the oil component has a high fat solubility, so that it can be suitably used for creams and the like, but other compounding agents are added to liquid hair styling products such as shampoos and rinses to stably disperse or dissolve them. In some cases, the selection of components was somewhat restricted.

[0005] Therefore, development of hair cosmetics having the effect of preventing damage to the hair and restoring and maintaining the original function of the hair by acting on the damaged hair, and cosmetics such as liquid hair styling and hair cosmetics In addition, cosmetic additives which can be used widely have been desired.

[0006]

As a result of repeated studies in view of the above problems, the present inventors have found that a quaternary ammonium salt of a branched fatty acid has a particularly strong hair damage suppressing action and a damage repairing action. It is also surprising that the hair damage caused by the hair cosmetic and the like can be significantly prevented and the damage once caused can be repaired by combining with a hair cosmetic such as a bleaching agent or a bleaching agent or a hair coloring agent that causes hair damage. Especially for dyeing hair dyes, etc.
It has been found that the color-developing effect is enhanced, and a deep-dyeing action for preventing color fading and fading due to hair washing and the like and improving color retention and a leveling action for uniformly dyeing without causing uneven dyeing are produced.

The present invention has been made based on such findings.

That is, the present invention provides the following items 1 to 7.

Item 1. A cosmetic additive containing a quaternary ammonium salt of a branched fatty acid as an essential component.

Item 2. A cosmetic composition containing a quaternary ammonium salt of a branched fatty acid.

A hair bundle having a size of 5 cm and a weight of 5 g was prepared, washed with a 5% shampoo solution, rinsed sufficiently with running water, and air-dried.
This was bleached, washed with water and dried to obtain a test sample. The test sample was immersed in a hair dye composition solution obtained by mixing the first and second agents in advance at 30 ° C. for 10 minutes, rinsed sufficiently with water, and air-dried. Next, the hair bundle was suspended in a thermo-hygrostat at 25 ° C. and a humidity of 70%, and left for a day to prepare a test piece.

Hair strength of the hair test piece after hair dyeing.
The deep dyeing effect and leveling effect by the dye were observed. The hair strength was evaluated according to the method described above, and the deep dyeing effect and the leveling effect were evaluated according to the following criteria. Table 5 shows the results.

[Table 5]

A comparison of the hair strength of the untreated hair, the bleached hair, and the comparative example shows that the hair is first damaged by the bleaching treatment and the strength is reduced, and further the hair is damaged by the hair dyeing treatment and the strength is further reduced.
In contrast, hair treated with a hair dye composition containing a quaternary ammonium salt of a branched fatty acid such as an IST cation or an NH cation exhibits strength equal to or higher than that of untreated hair, and is damaged by bleaching. It was found that the damaged hair was repaired and the damage caused by the hair dyeing treatment was also suppressed.

From the above results, it can be seen that the quaternary ammonium salt of a branched fatty acid has not only a hair damage-suppressing effect but also a damage-repairing effect, and exhibits a deep dyeing action and a level dyeing action on a hair dye. Became clear.

Examples 21 and 22 and Comparative Examples 23 to 25 Hair treated in advance with a permanent treatment and damaged was treated with a hair treatment solution having the formulation shown in Table 6 according to the method described above. The strength of the hair was compared before and after the treatment. The results are shown in Table 6.
