ABSTRACT
Igepal CO-630 is referenced in ASTM & CEN norms-test methods as the reagent for the stress cracking test. Unfortunately, it has now been listed as a priority pollutant by several counties because of a benzene ring in its formulation. As a result, it is no longer available for laboratory use in several locations, particularly in Europe (EU) and Canada. This event has manifested itself over the past several years. Obviously, our industry is searching for an alternative surfactant for this important performance test which can be used and is available globally. This paper will describe the search and round robin tests which lead to an alternative surfactant that conceivably will fill the need internationally.
