In the sulfonation and sulfation of alpha olefin (AO), linear alkylbenzene (LAB), and alcohol ethoxylate (AE), improved reaction yields and products’ color were obtained by using the TO‐Reactor recently developed in Lion Fat & Oil Co., Ltd., compared with those obtained in a conventional falling‐film type reactor. These improvements especially were remarkable in the case of AO, so that light‐colored alpha olefin sulfonate (AOS), having improved performance properties, was obtained without bleaching. For the performance tests, AOS was evaluated in several systems, together with some other surfactants, alcohol sulfate (AS), alcohol ethoxy sulfate (AES), linear alkylbenzene sulfonate (LAS), and alpha‐sulfo fatty acid methyl ester (a‐SEMe). AOS was one of the most useful surfactants for heavy duty powder detergents of low phosphate formulation because of its good detergency and foaming power, rinsing property, and free flowing property. Thus, bright white heavy duty powder detergents, containing 8% of P 2 O 5 , were developed with AOS (nonbleached), AES, LAS, sodium pyrophosphate (TSPP), and some other ingredients, which have been marketed in the household cleaning products field in Japan since 1976.
