The Aquaness ARBREAKTM 8280 Demulsifier is cationic in character and works by counteracting naturally occurring emulsifiers. This product has been found to be particularly effective when used in low salt water brine or in freshwater emulsions. In these cases, ARBREAK 8280 Demulsifier is often formulated with sulfonates, but may be used as is. ARBREAK 8280 Demulsifier exhibits exceptional ability to lower interfacial tension and, as a result, has a high degree of wetting activity. ARBREAK 8280 Demulsifier can be used with effectiveness in synergistic blends with oxyalkylated phenolic resins or with sulfonic acid salts, or in blends of all three, to break crude oil emulsions of the water-in-oil type.
