Abstract

Detergents and cleaning agents containing an anionic surfactant of general formula (I), in which n is a number from 5 to 21 and X+ is a charge-balancing cation. Also disclosed are an agent or a use, characterized in that, in the compound of general formula (I), X+ is selected from the group including the proton, alkali metal cations and the group N+R1R2R3, where R1, R2 and R3 are, independently of one another, hydrogen, an alkyl group with 1 to 6 C atoms or a hydroxyalkyl group with 2 to 6 C atoms.
