Abstract (en)

[origin: DE19648014A1] Novel water-free mixtures of surface-active agents, containing: (a) fatty alcohol sulfates with 16 and/or 18 carbon atoms and (b) alkyl benzosulfonates with 10-14 carbon atoms in the alkyl residue, in a weight ratio of 50:50 to 90:10. The mixtures are characterized by a synergistic reduction of irritation potential while maintaining excellent detergent properties.
