Our butyl-based TOXIMUL® series are multifunctional polymeric surfactants that are excellent emulsifiers in oil-based systems and come in a range of high ethylene oxide (EO) content. Our product line of low pour point materials has been developed with a range of hydrophilic-lipophilic balance (HLB) values, EO content and water solubility to enable formulators to find solutions for even the most challenging formulations.
When paired with low HLB surfactants, they create very good emulsifier combinations, making them ideal for EW systems.
In water-based systems, Stepan’s butyl-based block copolymers act as wetters and dispersants. Their high molecular weight (MW) allows them to have better adhesion to surfaces, giving formulators better dispersancies in systems like SCs.
They also can be paired with other nonionics and anionics to form stable systems.
