ABSTRACT:
This invention relates to a process for preparing secondary alkyl sulfate-containing surface active compositions substantially free of unreacted organic matter and water, which process comprises: a) sulfating a detergent range olefin having from about 8 to about 22 carbon atoms with concentrated sulfuric acid, b) neutralizing the product of step a) with a base dispersed in a nonionic surfactant having a boiling point higher than that of said detergent range olefin and its corresponding secondary alcohol, c) saponifying the product of step b), d) passing the product of step c) through a thin film evaporator to evaporate unreacted organic matter from said product and recovering said product.
