[0002]

2. Description of the Related Art In recent years,
Surfactants used as detergents are naturally required to have excellent surface activity (foamability / detergency), and are biodegradable, especially in the case of human detergents, they are safe. It is also required to have excellent physical properties such as low irritation to eyes and skin. Anionic surfactants (soap, linear alkylbenzene sulfonate (LAS), alkyl sulfate ester salt (AS), polyoxyethylene alkyl ether sulfate ester salt (AES), α
-Olefin sulfonate (AOS) etc. have good detergency and foamability, but on the other hand, they are irritating to eyes and skin. On the other hand, monoalkyl phosphates, N-acyl glutamate, N-acyl-N-alkyl-β-alanine salts, N-acyl-N, which have been proposed as mild activators,
-Alkylglycine salts and other N-acyl amino acid salts have low irritation, but are inferior to the original properties of detergents such as hard water resistance, foaming property and detergency.

Therefore, there has been a strong demand for a shampoo which has a low irritation to hair and skin and which is excellent in detergency, foamability, foam quality and hard water resistance, and also has an excellent conditioning effect.
