| 1 | For maximum effectiveness, the surfactant heads should be highly ionized. | |
| 2 | The research of borate ester surfactants is still in the initial stage. | |
| 3 | Rough-surfaced mints without the surfactant did not create such large fountains. | |
| 4 | Adsorbed ionic surfactants and their associated electrostatic repulsions stabilize detergent films. | |
| 5 | Shampoos usually contain a cocktail of surfactants, artfully combined to strike the right balance. |
