The invention relates to the use of N-methyl-N-acylglucamines as cold stabilizers in aqueous surfactant solutions, wherein at least 90 wt.-% of the N-methyl-N-acylglucamines have a C 8 -acyl or C 10 -acyl group. The invention further relates to compositions containing (a) N-methyl-N-acylglucamines, wherein at least 90 wt.-% of the N-methyl-N-acylglucamines have a C 8 -acyl or C 10 -acyl group as component (A), (b) one or more anionic surfactants as component (B), (c) one or more betaine surfactants as component (C), (d) optionally additional surfactants as component (D), (e) water as component (E), and (f) optionally additional additives as component (F). |
