ABSTRACT:
A surfactant composition comprising:alkylarylsulfonate surfactant system comprising at least two isomers of the alkylarylsulfonate surfactant of the formula:wherein:L is an acyclic aliphatic hydrocarbyl of from 6 to 18 carbon atoms in total;M is a cation or cation mixture and q is the valence thereof;a and b are numbers selected such that said composition is electroneutral;R′ is selected from H and C1to C3alkyl;R″ is selected from H and C1to C3alkyl;R′″ is selected from H and C1to C3alkyl;any of R′ and R″ is nonterminally attached to L and at least one of R′ and R″ is C1to C3alkyl; andA is aryl; andwherein:said alkylarylsulfonate surfactant system comprises two or more isomers with respect to positions of attachment of R′, R″ and A to L;in at least about 60% of said composition, A is attached to L in the position which is selected from positions alpha- and beta- to either of the two terminal carbon atoms thereof; andwherein further said alkylarylsulfonate surfactant system has at least one (preferably both) of the following properties:said alkylarylsulfonate surfactant system has a ratio of nonquaternary to quaternary carbon atoms in L of at least about 10:1 by weight, when said quaternary carbon atoms are present; andthere is no more than 40% by weight loss as measured by Hardness Tolerance Test.
