Abstract The invention provides surfactants excellent in the balance among detergency against oily stains, rinsability, handleability and handling safety. Namely, secondary alkyl ether sulfate salt type anionic surfactants of the general formula (1) having average chain lengths of polyalkylene ether of 1.5 to 2.5; and compositions containing the surfactants: wherein R1 and R2 are each independently straight-chain or branched alkyl having 1 to 18 carbon atoms, with the total number of carbon atoms of both being 7 to 29; A is alkylene having two or more carbon atoms; n is the number of oxyalkylene repeating units and the average of n's is 1.5 to 2.5; M is alkali metal, alkaline earth metal, ammonium, or substituted ammonium; and m is the valence of M. L'invention prévoit des tensioactifs excellents en matière d'équilibre entre le pouvoir détergent contre les taches graisseuses, la rinçabilité, la manipulation et la sécurité de traitement. A savoir, des tensioactifs anioniques de type sel secondaire de sulfate d'éther alkyle de la formule générale (1) ayant des longueurs de chaîne moyennes d'éther de polyalkylène de 1,5 à 2,5; et des compositions contenant les tensioactifs : où R1 et R2 sont chacun indépendamment un alkyle à chaîne droite ou ramifié ayant 1 à 18 atomes de carbone, le nombre total d'atomes de carbone des deux étant compris entre 7 et 29; A est un alkylène possédant deux atomes de carbone ou davantage ; n est le nombre de motifs de répétition d'oxyalkylène et la moyenne de n est comprise entre 1,5 et 2,5 ; M est un métal alcalin, un métal alcalinoterreux, de l'ammonium ou de l'ammonium substitué ; et m est la valence de M.
