Description

The present invention relates to a permanent wave and post-treatment composition for straightening hair. More specifically, the present invention is a permanent wave that can efficiently suppress the residual odor of mercaptan odor and hydrogen sulfide odor that occurs when the hair is subjected to permanent wave treatment and hair straightening treatment. The agent composition.

Hair is a very important part in cosmetics, and various cosmetic treatments are performed. Of these, the permanent wave method and the hair straightening method are the most effective in setting hair. A permanent wave agent and a permanent agent for straightening hair are composed of a first agent containing a reducing agent and the like, and a second agent containing an oxidizing agent and the like. The reducing agent contained in the first agent has a function of chemically cleaving the disulfide bond of cystine, a hair protein, and the oxidizing agent contained in the second agent regenerates the disulfide bond at a new site. And has the function of stabilizing the shape of the hair.

And as said reducing agent, organic thiol compounds, such as thioglycolic acid or its salt, cysteine or its salt, acetylcysteine or its salt, thiolactic acid or its salt, cysteamine or its salt, thioglycerol, glyceryl thioglycolic acid ester, etc. Is used.

These organic thiol compounds not only cleave disulfide bonds in the hair, but also cause a chemical reaction with sulfur compounds such as cystine in the hair or with the thiol compounds themselves to produce low molecular sulfur compounds. Mercaptan odor and hydrogen sulfide odor of this low molecular weight compound are unpleasant and unique odors called so-called perm odors, which remain on the hair for several weeks after the treatment, and desorb and diffuse during hair washing and sweating, causing extreme discomfort to the patient. Has the disadvantage of giving.

Several techniques have been disclosed for such an unpleasant odor that occurs during the perm treatment. For example, a treatment agent that suppresses an unpleasant odor by applying an acidic post-treatment agent to permanent wave or hair after straightening treatment (see Patent Document 1), and a deodorant containing a specific polymer (see Patent Document 2) ), There are reports of hair deodorizing agents containing divalent metal ions (see Patent Document 3), but none of them satisfy the problem of reducing unpleasant odors, and the hair feels stiff. There was a problem that an unpleasant feel such as a squeaky sensation was produced and the finished feeling was impaired.

As described above, conventional permanent wave and post-treatment agents for straightening hair are not satisfactory in suppressing the unpleasant odor, and the post-treatment having a high effect of suppressing the permanent odor such as mercaptan odor and hydrogen sulfide odor. Development of an agent was desired.
