DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a permanent wave intermediate treatment, and more particularly to a permanent wave intermediate treatment used for hair when performing a wave or straightening treatment using an iron.

[0002]

2. Description of the Related Art Permanent wave is a method of reducing hair using a reducing agent such as thioglycolic acid, and then fixing the wave with an oxidizing agent such as bromic acid or hydrogen peroxide. As a method of the permanent wave, there is a method of performing a permanent wave using an iron in order to further strengthen the wave. These are called iron perm, eye perm, iron curly straightening perm, etc. The general processing steps are (1) applying the first permanent wave agent to the hair, leaving it for a predetermined time,
Rinse (2) The hair is then lightly dried and
The wave is formed by the heat of the iron heated to 0 ° C., and the hair is straightened. (3) Next, the permanent wave second agent is applied, left to stand, and then rinsed.

[0003] When treating hair with an iron, permanent wave intermediate treatment is performed for the purpose of improving the operability such as improving the slip of the iron to reduce the catch on the hair and protecting the hair from the heat of the iron. Agent is used. These conventional permanent wave intermediate treatment agents were blended with a paraffinic oil, a wetting agent, and the like as main components.

[0004] However, when applying these permanent waving intermediate treatment agents when applying a permanent waving using an iron, the oil and the like to be mixed inhibit the permeation of the permanent waving second agent, and the hair is sufficiently oxidized. In addition, these oils and the like generated smoke when they came into contact with the iron, giving both the iron perm practitioner and the practitioner discomfort. After all the steps of the permanent treatment are finished, the hair is washed, but these oils remain on the hair and do not fall off, giving a finish that is sticky and heavy.

[0005]

SUMMARY OF THE INVENTION The present invention has been made under such circumstances, and it is an object of the present invention to maintain the ability to form a permanent wave without inhibiting the penetration of the second agent of the permanent wave. Another object of the present invention is to provide a permanent wave intermediate treatment agent which prevents hair damage due to heat of an iron, suppresses generation of smoke accompanying the ironing treatment, and is excellent in washing off.

[0006]

Under such circumstances, the present inventors have made intensive studies and found that polypropylene glycol, polyoxyethylene polyoxypropylene glycol, polyoxypropylene alkyl ether, polyoxyethylene polyoxypropylene alkyl. A propylene oxide polymer such as ether maintains the ability to form a permanent wave without inhibiting the penetration of the second permanent wave into the hair, protects the hair from the heat of the iron, and suppresses the generation of smoke associated with the ironing process. The present invention was found to be excellent in washing and washing off, and completed the present invention.

That is, the present invention provides a compound represented by the following general formula (I):
