    摘要: Surfactant mixtures comprising (a) a nonionic surfactant mixture present in an amount greater than 60% by weight, based on the weight of the surfactant mixture, the nonionic surfactant mixture comprising: (i) at least one alk(en)yl oligoglycoside of the general formula (I), R1O—[G]p  (I) wherein R1 represents an alk(en)yl radical having from 4 to 22 carbon atoms, G represents a sugar radical having 5 or 6 carbon atoms and p represents a number from 1 to 10; and (ii) at least one nonionic surfactant of the general formula (II) R2O(CH2CHRO)xH  (II) wherein x represents a number of from 1 to 30, each R independently represents a substituent selected from the group consisting of a hydrogen, a methyl group and an ethyl group, and R2 represents a linear alkyl radical having from 16 to 22 carbon atoms; and (b) up to 6% by weight, based on the weight of the surfactant mixture, of one or more anionic surfactants; are described. Additional mixtures further comprising additional alcohol alkoxylates are also described. Solid laundry detergent compositions comprising such surfactant mixtures are described as well.
