摘要： A surfactant composition comprising alkylarylsulfonate molecules wherein more than 30 wt.% of the alkylarylsulfonate molecules of the surfactant composition are one or more species of the formula: [R - X - Ar (SO
3 )
- ]
a [M
n+ ]
b wherein: X is a linear acyclic aliphatic hydrocarbyl chain; R is bound to a non-terminal carbon atom of X and is selected from H and C1, C2, and C3 alkyl groups; X and R together have 9 or 10 carbon atoms; Ar is an aromatic group; M is a cation, n is selected from 1,2 and 3; and a and b are selected such that the alkylarylsulfonate molecule is electroneutral, wherein more than 20 wt.% of the alkylaryl molecules of the surfactant composition have an R which is methyl or ethyl.
