Zephrym 3300B is an anionic surfactant which is a highly efficient emulsifier and dispersant. It finds use in Emulsifiable Concentrates. Microemulsions usually contain an anionic surfactant and a combination of nonionic surfactants. The combination of Zephrym 3300B and nonionics such as the Synperonic A series help to formulate Microemulsions with excellent stability and optical clarity. To find out more about how to formulate Emulsifiable Concentrates and Microemulsions please refer to the relevant chapter of the Formulator's Toolbox.
