Environmental and Human Safety of Major Surfactants. Volume 1. Anionic Surfactants. Part 4. Alpha Olefin Sulfonates

摘要

Alpha olefin sulfonates (AOS) have been available since the 1930s. AOS are reportedly efficient, readily biodegradable cleaning agents. They offer detergency and foam properties comparable to those of lauric acid sulfonates (LAS) and possibly possess a slight advantage over LAS in hard water. AOS also possess a high degree of stability and have good water solubility characteristics. The review was prepared to evaluate the information currently available on AOS with respect to: (1) environmental fate and distribution including biodegradation; (2) effects on wild and domestic flora and fauna; and (3) product use and safety for humans as indicated by tests with laboratory animals and by data on human exposure.
