acylamino acid and an alkali salt of an amino acid, and also relates to a detergent composition comprising this surfactant as a cleansing component and an emulsion composition comprising this surfactant as an emulsifying component. In the alkali salt of an amino acid, a suitable amino acid is an acidic or neutral α-amino acid, and a suitable alkali is sodium, potassium, triethanolamine, or N-methyltaurine sodium. In the N—C
