Abstract

Disclosed are detergent mixtures of alkyl aryl sulfonates of alkaline earth metals derived from linear olefins having a relatively high aryl ring attached on positions 1 or 2 or the linear alkyl chains. The compositions contain a relatively high amount of 1 or 2 tolyl or xylyl isomer of the linear alkylaryl sulfonate and employ a heavy alkyl benzene sulfonate derived from linear olefins and exhibit improved stability and compatibility.
