Abstract

Surfactants of general formula (I), in which R1 denotes a linear or branched alkyl residue having 6 to 20, and in particular 8 to 14 carbon atoms, R2 denotes H or CH3, and M denotes hydrogen, an alkali metal or an N+R3R4R5 grouping, in which R3, R4 and R5, independently of one another, denote hydrogen, an alkyl group having 1 to 6 carbon atoms or a hydroxyalkyl group having 2 to 6 carbon atom, can be easily incorporated into washing or cleaning agents, have outstanding application-related properties, and can be produced based on renewable resources.
