Berol® 609 is a nonionic surfactant designed for nonyl phenol 9 replacement.
Berol® 609 is intended to be used as a direct drop-in for NP9 or NP10. Similar surfactant properties (cloud point equal to NP9). Better handling characteristics (lower pour point and viscosity, dissolves much more quickly in cold water). No need to modify other components of existing formulations to maintain performance.
