The physicochemical properties of sodium long chain N‐acylglutamate (AGS n ) are described. The wetting power, emulsifying power, dispersing power and calcium ion stability were measured. Monosodium N‐lauroyl‐ l ‐glutamate ( l ‐LGS) had good wetting and emulsifying properties, but disodium N‐acylglutamate (AGS 2 ) was inferior to l ‐LGS in those properties. In the dispersing power using carbon black as powder, l ‐LGS was inferior but AGS 2 , having a palmitoyl or stearoyl radical, was excellent. The AGS n with a few exceptions had good calcium ion stabilities.
