(Prior art and problems) S, 2-aminoethylisothioureas are known as radioprotective substances. For example, J. Am. Chem. Soc., 79 , 5663
As described in (1957), S, 2-aminoethylisothiourea changes depending on the hydrogen ion concentration and decomposes to 2-aminothiazoline and the like.

On the other hand, at present, there are two types of permanent wave liquids, the first agent of which is mainly composed of thioglycolic acid or a salt thereof, and the one of which is mainly composed of cysteine. Since the latter type has a weak wave-forming ability, the former type is often used to obtain a strong wave.

However, a perm solution composed of thioglycolic acid actually uses ammonia, monoethanolamine, or the like as an alkaline agent, and must be used under strong alkaline conditions of about pH 9.0 to 9.4, resulting in strong skin irritation.

(In the formula, HA: monobasic acid, n: 0 or 1) Focusing on the characteristics of the above-described novel isothiourea, a test was conducted on human hair, and as a result, it was found that the hair was weakly alkaline and exhibited a remarkable wave effect. This compound (I) has a significantly higher wave effect than the commonly used thioglycolic acid, as shown in the test examples, and is used as a stable permanent wave first liquid without generating offensive odor. You can do it. Currently, the first liquid of permanent wave is used on the strongly alkaline side around pH = 9.0-9.4, but this compound formulation can be used at pH = 8.0-9.0 and prevents hair damage by using it on the lower alkaline side. You can do it. In the present invention, ammonia water, ethanolamine, ammonium salts and the like are suitable as the pH adjusting alkali agent. The pH may be adjusted from the beginning and used, or the compound of the present invention and the alkali adjuster may be separately adjusted at the place of use.
