Historically, Calcium Dodecylbenzene Sulfonates (CaDDBS) have been used as emulsifiers in Clethodim Emulsifiable Concentrate (EC) formulations. These emulsifiers have been shown to offer good emulsification properties, but tend to promote the degradation of Clethodim, while also displaying unfavorable regulatory handling language. In many instances, these products are formulated above the target amount of Clethodim to account for this degradation. The practice of using increased amounts of Clethodim is costly and could lead to regulatory issues. As a result of the problems associated with using CaDDBS, Stepan Company created a new anionic/nonionic emulsifier system for Clethodim EC formulations that shows comparable emulsification performance with improved Clethodim stability and regulatory handling language over the traditional CaDDBS-based emulsifiers.
