2. Description of the Related Art A detergent composition for body and hair generally contains an anionic surfactant as a main component, and the anionic surfactant is a sulfosuccinic acid type, isethionate type or taurate type sulfonic acid type or sulfate salt. Type anionic surfactants are widely used.

However, although the detergents containing these anionic surfactants as the main ingredients are excellent in the cleaning effect, they are not good in defoaming at the time of rinsing and have a feeling of use such as feeling slimy to the skin after washing. There was a problem in terms. Furthermore, when a sulfate type surfactant is used, there is a problem in that it is irritating to the skin and hair.

On the other hand, a surfactant other than an anionic surfactant, for example, a detergent containing an amphoteric surfactant as a main component or an anionic surfactant is reduced in amount, and another surfactant is contained as a main component. Although detergents and the like have been developed, it is difficult to obtain a sufficiently satisfactory detergent due to the fact that the detergent effect and the foaming power are deteriorated, and the improvement is likely to result in restrictions on formulation.

That is, glycine represented by the general formula (3) or a salt thereof is reacted with acrylonitrile to obtain a glycine derivative (4) or a salt thereof (step A), which is hydrolyzed and, if necessary, a salt.

The glycine derivative (4) or a salt thereof can be obtained by reacting for a time, preferably 1 to 3 hours, and if necessary, by exchanging a counter ion with an electrodialyzer or the like. When the reaction time is longer than 100 hours, side reactions such as hydrolysis of the cyano group occur concurrently, which is not preferable. During the reaction, it is preferable that a treatment such as gradually adding acrylonitrile to an aqueous solution of glycine (3) or a salt thereof is performed because side reactions such as polymerization of acrylonitrile are significantly suppressed and the yield is improved. The glycine derivative (4) or a salt thereof obtained in this step can be used as it is in the next step, but if necessary, it may be recrystallized using a solvent such as water, methanol, ethanol, etc. It can also be a product.

(Step B) In this step, the cyano group of the glycine derivative (4) or salt thereof obtained in step A is hydrolyzed, preferably in the presence of a basic substance, to give a glycine derivative (7) or its salt. This is the step of obtaining salt.

0.5-at a suitable temperature of 0 ° C, preferably 10-50 ° C
The glycine derivative (2) or a salt thereof can be obtained by reacting for 100 hours and exchanging counterions with an electrodialyzer or the like if necessary. If the amount of acid chloride (5) used is less than the above range, a large amount of the glycine derivative (7) or its salt remains in the reaction product. A large amount of fatty acid is by-produced from the acid chloride (5), which is not preferable.

In this step, in order to secure the reactivity and allow a certain reaction to proceed, an alkaline substance is added to the reaction system to bring the pH in the system to the alkaline side, preferably pH 9.0 to 9.0.
