Solvay Clearbreak 7390 Surfactant

Solvay Clearbreak 7390 is a high-performance nonionic surfactant from the Clearbreak series, engineered for rapid oilfield demulsification. It delivers exceptional water-in-oil emulsion breaking efficiency under harsh conditions—high temperature, high salinity, and heavy crude. Widely used in upstream production, it ensures clean separation, reduced carryover, and compliance with environmental standards.
