[Appearance] Generally colorless to light yellow, free-flowing, uniform liquid.
[Physical and Chemical Properties]
Oilfield surfactant-type oil displacing agents are amphiphilic chemicals consisting of a hydrophilic group and a hydrophobic (lipophilic) group. The hydrophobic part is usually a long-chain hydrocarbon group mainly composed of carbon and hydrogen, while the hydrophilic part consists of ionic or nonionic polar groups. This structure enables the surfactant to adsorb at the oil-water interface, reducing interfacial tension and thereby enhancing oil recovery.
