The present invention relates to a surfactant composition comprising: a) at least one anionic surfactant, and b) at least one compound selected from amphoteric surfactants and nonionic surfactants, wherein the active ingredient total of said surfactants is from 25 to 55% by weight relative to the total weight of said composition, in which the anionic surfactant ratio is between 0.3 and 0.9, the ratio of surfactant amphoteric is from 0.0 to 0.7 and the ratio of nonionic surfactant is from 0.0 to 0.7, said ratio being the ratio between the percentage by weight of active ingredient of said surfactant in said composition and the percentage by weight of total active ingredient of said surfactants in said composition, the pH of the composition being between 4 and 8. The present invention also relates to a cosmetic or dermatological composition comprising a surfactant composition of the inventio not. The present invention furthermore relates to a non-therapeutic cosmetic treatment method comprising the application to the skin and / or integuments of a surfactant composition of the invention or a cosmetic composition of the invention, as well as to a combination of a spray-generating device and a surfactant composition or a cosmetic composition of the invention, wherein said spray-generating device diffuses said cosmetic composition into spray. La présente invention se rapporte à une composition de surfactant comprenant : a) au moins un tensio-actif anionique, et b) au moins un composé choisi parmi les tensio-actif amphotères et les tensio-actif non-ioniques, dans laquelle la matière active totale desdits tensio-actifs est comprise de 25 à 55% en poids par rapport au poids total de la dite composition, dans laquelle le ratio de tensio-actif anionique est compris de 0,3 à 0,9, le ratio de tensio-actif amphotère est compris de 0,0 à 0.7 et le ratio de tensio-actif non-ionique est compris de 0,0 à 0,7, ledit ratio étant le rapport entre le p
