Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is used after a permanent wave first agent or a hair straightening first agent to suppress damage to the hair and enhance the wave effect or straightening effect of the hair. The present invention relates to a permanent wave intermediate treatment agent composition for reducing the above-mentioned amount, and a permanent wave treatment method using the composition.

2. Description of the Related Art Generally, a permanent wave method or a straightening method for curly hair is a first agent containing thioglycolic acid or a salt thereof and a reducing agent such as cysteine or a cysteine derivative as a main agent, and S-S in hair. The bond is reductively opened and the hair is kept in a wavy or straight state using a rod or a comb, and then a second agent whose main agent is an oxidant such as bromate, perborate or hydrogen peroxide is used. It is a method of oxidatively closing the S—S bond in hair and fixing it in a wave or straight state.

However, in these methods, when the S--S bond in the hair is cleaved, a mixed disulfide in which a mercapto compound is bonded to a cysteine residue in the hair is produced, or lanthionine is produced. , And sometimes the hair strength, the feel, and the wave down. Further, in order to enhance the wave effect and straight effect of the hair, it is possible to re-apply the first agent to extend the standing time, but in this case, there is a concern that the hair may be damaged due to overtime. For this reason, various permanent wave intermediate treatment agent compositions have been conventionally proposed in order to improve these drawbacks. For example, JP
2-246509 proposes a combination of a keratin hydrolyzate and a cationic activator, which suppresses the deterioration of hair and improves the wave-forming ability. However, since it is a treatment agent having an acidic pH, hair is treated with an acid. If it suddenly converges, there is a risk that hair damage and the feel may be reduced. In addition, JP-A-5
-294814 proposes that a carbonate or hydrogen carbonate is blended, but it is used for an acidic to weakly alkaline permanent waving agent, and a general alkaline permanent waving agent has a sufficient wave forming power. It didn't improve. Furthermore, in a general permanent waving agent, an unpleasant odor such as hydrogen sulfide and methyl mercaptan is generated during the treatment, so that the practitioner and the subject are uncomfortable. Furthermore, this unpleasant odor often remained after the perm treatment. Therefore, there is a sulfite curling agent using sulfite or bisulfite which has no unpleasant odor and has a mild effect on hair. However, since these have a weak reducing power, a sufficient wave is formed. It had the drawback of not being able to.

[0004]

Therefore, in the conventional permanent treatment, the wave effect or straight effect can be easily enhanced without damaging the hair or impairing the feeling,
Further, it has been desired to develop a permanent wave intermediate treatment agent composition capable of reducing unpleasant odor and a treatment method therefor.

[0005]

In this situation, as a result of intensive studies by the present inventor, the present inventor contains one or more selected from the group consisting of sulfite and bisulfite, and further contains silicone. It has been found that the use of a permanent wave intermediate treatment agent composition containing a derivative and a polyhydric alcohol enhances the wave effect or straightening effect while suppressing hair damage, and further reduces unpleasant odor. Has been completed. That is, the present invention provides a permanent wave intermediate treatment agent composition containing (A) sulfite or bisulfite, (B) silicone derivative and (C) polyhydric alcohol and having a pH of 7 to 11.
