Abstract from a study on anionic gemini surfactants:

"...The results obtained from the present study show that the anionic gemini surfactants give unusual properties at the air/water interface and in bulk solution. As expected, the gemini surfactants show fairly low cmc and high efficiency in lowering surface tension. The areas per molecule of the gemini surfactants are narrow, indicating close packing at the air/water interface."
