Zusammenfassung:The present invention relates to a surfactant composition capable of making a liquid oil highly remain on the solid surface, which is a surfactant composition containing an anionic surfactant (A), a cationic surfactant (B), a liquid oil (C), and water, wherein the water constitutes a continuous phase; the following molar ratio RA is 0.25 or more and 0.60 or less; and the following molar ratio Rb is 0.6 or more:RA: a molar ratio {(A)/[(A) + (B)]} of the amount of the anionic surfactant (A) to the total amount of the anionic surfactant (A) and the cationic surfactant (B)Rb: a molar ratio {[(a1) + (b1)]/[(A) + (B)]} of the total amount of a branched-type anionic surfactant (a1) and a branched-type cationic surfactant (b1) to the total amount of the anionic surfactant (A) and the cationic surfactant (B).
