Abstract:
1. A surfactant composition comprising alkylarylsulfonate molecules wherein more than 50 wt. % of the alkylarylsulfonate molecules of the surfactant composition are species of the formula: wherein: X is a linear acyclic aliphatic hydrocarbyl chain; R is bound to a non-terminal carbon atom of X and is selected from C1 to C3 alkyl groups; X and R together consist essentially of 10 carbon atoms; Ar is an aromatic group; M is a cation or cation mixture, n is selected from 1, 2 and 3; and a and b are selected such that the alkylarylsulfonate molecule is electroneutral; and wherein more than 20 wt % of the alkylarylsulfonate molecules of the surfactant composition have an R which is methyl; and more than 40 wt % of the alkylarylsulfonate molecules of the surfactant composition have the aryl group bound to the carbon atom which is bound to either of the two terminal carbon atoms of X, which is the beta position on the hydrocarbyl chain X.
