Abstract
This invention is directed to detergent compositions which employ sulfonated linear alkylbenzenes as surfactants, wherein the sulfonated linear alkylbenzenes have a higher content of the sulfonated 2-phenyl alkylbenzene isomers than was previously available in sulfonated phenyl alkylbenzene surfactants of the prior art. Cleaning compositions according to the invention are more effective as cleaning agents over their counterparts of prior art which contain sulfonated linear alkylbenzenes having lower contents of the 2-phenyl alkylbenzene isomers, owing to an unexpected increase in tolerance of water hardness minerals normally associated with precipitation of the active detergent agent. Solid sulfonate salts of alkylbenzenes are also provided, including dry formulations containing same.
