Patent number: 11879093Abstract: A method for inhibiting corrosion of pipelines and other metal surfaces, particularly those used in the oil-and-gas industry, is disclosed. The method comprises treating a brine-exposed metal surface with a film-forming composition. The composition comprises a quaternary surfactant, which is made by reacting a polyalkylene glycol (PAG), a haloalkanoic acid, and a tertiary fatty amine that optionally incorporates amide or ester functionality. The surfactant comprises a PAG monoester quat and a PAG diester diquat and may have other components. The quaternary surfactants provide good corrosion protection and can partition effectively from an oily phase into a brine phase in the absence of agitation. The surfactants are easy to synthesize economically and have structures that can be tailored to meet local HLB requirements.Type: GrantFiled: July 29, 2020Date of Patent: January 23, 2024Assignee: STEPAN COMPANYInventors: Maxime Feche, Mathieu Pepin, Elodie Shaw, Laure Canal, José Santiago, Milan Bartos, Alla Crabtree

Publication number: 20230018007Abstract: Agricultural compositions that employ structured surfactant systems to suspend water-insoluble or sparingly soluble agricultural actives and/or adjuvants are disclosed. Also disclosed are agricultural compositions that combine structured surfactant systems with electrolytes to form structured electrolyte compositions. The structured surfactant systems, both with and without electrolyte, suspend one or more agricultural actives and/or crop oil and non-aqueous adjuvants to provide agricultural compositions that can combine combinations of actives in a single, stable composition.Type: ApplicationFiled: September 12, 2022Publication date: January 19, 2023Inventors: Kelly Buchek, Eric M. Weber, Elodie Shaw, Krista Turpin, Andrea B.E. Brayton, Julien Guillan, Dave R. Allen
