1. These compounds are nitrogenous cationic surface active agents. 2. Lactylates are surface active and are therefore surfactants. 3. The surface active component is usually labeled with carbon-14 or sulfur-35. 4. For the more general meaning, " surface active agent / s " is the heading. 5. Some of the chemical properties of activated carbon have been attributed to presence of the surface active carbon double bond. 6. His research during recent years has had a focus on the behavior of surface active compounds in solution and at interfaces. 7. Additionally, the Gibbs surface excess of a surface active component for an aqueous solution can be found using the radioactive tracer method. 8. Due to its surface active properties, ?-cyclodextrin can also be used as an emulsifying fiber, for example in mayonnaise. 9. In most of these products, proteins are the main surface active agents that help in the formation and stabilization of the dispersed gas phase. 10. Surfactants own both hydrophilic and lipophilic properties in one molecule, so they are called surface active agents, and are widely used in various washing process.
