2. Description of the Related Art When hair, which is one of substances containing keratin (hereinafter referred to as keratin substance), is subjected to a set treatment or a permanent wave treatment, a reducing agent is applied to the hair. It is well known that it is often damaged. That is, in the treatment, a reducing agent is allowed to act on the hair to cleave the cystine disulfide (-S-S-) bond contained in the hair, followed by treatment such as setting, and then sodium bromate or peroxide. It is oxidized by hydrogen or the like to regenerate the disulfide bond.
At that time, in order to more effectively perform the above-mentioned reducing action and improve the durability of the set, it is usual to use an alkaline agent such as ammonia or monoethanolamine together so that the reducing agent acts in a high pH range. It is being appreciated. Therefore, a part of the components of the hair is eluted and the hair is significantly damaged, and in particular, a part of cystine in the hair causes a chemical change to cysteic acid and the like due to an oxidizing agent which acts subsequently, and it is difficult to return to cystine again. Become.

As a method of protecting the hair from damages, a method using a keratin hydrolyzate or the like (JP-A-57-165310), a collagen hydrolyzate or a silk hydrolyzate is blended in a hair cosmetic composition. A method for protecting hair (Japanese Patent Laid-Open No. 60-112710) is known, but it is still not sufficient. Therefore, it is a treating agent for keratin substances, protects keratin substances without damaging the above, and further imparts a setting effect to the keratin substances, giving an excellent texture and elastic wave. It is desired to develop those having such effects.

(End paper for permanent wave, paper containing alkaline aqueous solution of reducing agent having disulfide bond-cleaving action in which eggshell membrane is dipped) Fine powder of eggshell membrane when the present invention is used for permanent wave treatment It is also possible to disperse the eggshell membrane fine powder and the fiber composition in water to prepare a paper stock, and use it as a paper made with the eggshell membrane fine powder blended paper.

The production method of this egg shell membrane fine powder blended paper is as follows:
For example, it is possible to use the method disclosed in Japanese Patent Laid-Open No. 9-176998. The eggshell membrane fine powder blended paper has a uniform and wide distribution of the fiber structure of the eggshell membrane, and the contact area with the outside air increases, so that the active action of the eggshell membrane fine powder can be greatly expanded. When this is used as an end paper during the permanent wave treatment, it can directly act on the hair surface during the treatment with the reducing agent and can prevent damage such as protection and peeling of the cuticle. In addition,
By processing this compounded paper as thinly as possible, it does not hinder the winding technique and can be effectively applied to the bristle tips that tend to be damaged.

(Keratin substance) The keratin substance which can be treated by the present invention means a substance containing keratin in a part (including a part of the surface) or the whole thereof. Further, the substance includes a substance derived from a living body, a substance derived from a living body but processed, or an artificial substance.

More specifically, it includes human hair, animal hair, bird feathers, bird feathers, and the like. As animal hair,
For example, including animal hairs for pet animals such as dogs and cats, wool, mink hair, normal goat hair, mohair hair, Tibetan hair, camel hair, cashmere hair, llama hair, alpaca hair, guanaco hair, angora rabbit hair. , Cow hair, normal rabbit hair, horse hair, cat hair,

Examples include animal hair fibers such as non-woven fabrics and fur products. Examples of the feathers and feathers of birds include feathers and feathers of moths, ducks, other water birds, chickens and the like.

(Method of use) When the above-mentioned keratin substance is human hair, the treating agent of the present invention can be used as a hair protecting agent, a strengthening agent or a setting agent, and it can damage the hair. It can also be used as a permanent waving agent with a low level of protection.

When the treating agent of the present invention is used as a permanent wave agent, the treating agent of the present invention itself is used as the first agent for the permanent wave, or it is used for a permanent wave different from the treating agent of the present invention. The first agent can be used at the same time or in a mixture. Here, the permanent wave agent means a cold type permanent wave agent, a heating type permanent wave agent, a straight permanent wave agent, and a curling agent using a sulfite or the like. When used in the same manner as a straight perm or the like, if necessary, a slightly higher pH (pH 1) than the conventional first agent for permanent wave is used.
It can be adjusted to about 0) before use.

The treatment agent of the present invention contains a fine powder of eggshell membrane, which is a keratin substance, and a reducing agent having a disulfide bond-cleaving action. Therefore, at least a part of the disulfide bond of keratin that constitutes the eggshell membrane fine powder is cleaved by the reducing agent. When this treatment agent is applied to the keratin substance to be treated, for example hair, the cleaved keratin adheres to the hair. When the disulfide bond is subsequently regenerated on the hair by air oxidation or chemical oxidation, the cleaved keratin is crosslinked on the hair, so that the hair can be protected, strengthened, or imparted with specific properties to the hair. Further, when the treatment agent is applied to the keratin substance to be treated, a part of the disulfide bond of the keratin substance to be treated may be cleaved by the reducing agent in the treatment agent. Regeneration of disulfide bonds may occur between the cleaved keratin and the cleaved keratin of the eggshell membrane fine powder. Furthermore, the keratin substances to be treated may be cross-linked by regeneration of disulfide bonds between the cleaved keratin derived from the eggshell membrane fine powder.
Thereby, for example, when the keratin substance to be treated is hair, it is effective for protecting the cuticle on the surface of the hair and maintaining the hair strength.

A part of the cleaved keratin derived from the eggshell membrane fine powder is dissolved in the solution depending on the concentration and pH of the reducing agent in the treating agent solution. The degree of dissolution depends on the concentration of the reducing agent in the solution. Is higher, and the more alkaline the pH is, the higher the amount.
There is no problem whether or not the cleaved keratin derived from the eggshell membrane fine powder is dissolved in the liquid, but for example, the eggshell membrane fine powder is used particularly for the purpose of protecting the hair surface cuticle and maintaining the hair strength. First, in order to dissolve a large amount of the cleaved keratin from the origin, a high pH (pH 11 to 13)
After the eggshell membrane fine powder is placed in the area, the pH is lowered and the once-dissolved cleaved keratin derived from the eggshell membrane fine powder can be dispersed in a gel for use.

Furthermore, the treatment agent according to the present invention can be applied to wool, and by doing so, it becomes possible to modify the wool and to obtain an excellent finish in texture and the like.
