However, soaps used for cleansing the skin have the drawback that they produce squeaky and taut during rinsing, and the alkyl sulphates and alkyl sulphonates used for cleaning hair are excellent in detergency but irritating. I had a problem with.

[0003] Therefore, the use of a specific N-acylated amino acid type surfactant as a main base of a detergent has been studied as a surfactant having excellent feeling upon use and low irritation.
This alone has poor foaming properties, and the foam is coarse,
The texture was unreliable, and was not sufficiently satisfactory at a practical level.

[0004]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a low irritation, excellent foaming property, a fine foam texture, good foam removal, and a good feeling of use after washing. An object of the present invention is to provide a cleaning composition excellent in the above.

The glycine derivative (3) 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 to carry out a treatment such as gradually adding acrylonitrile to an aqueous solution of glycine (2) or a salt thereof, because side reactions such as polymerization of acrylonitrile are significantly suppressed and the yield is improved. The glycine derivative (3) 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.

The glycine derivative (1) or a salt thereof can be obtained by reacting for 100 hours and exchanging the counter ion with an electrodialyzer or the like if necessary. If the amount of the acid chloride (4) used is less than the above range, a large amount of the glycine derivative (6) or a salt thereof remains in the reaction product. A large amount of fatty acid is by-produced from the acid chloride (4), 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.
