They form only below a packing parameter of one-third.
Brij-35 ("bridge"-35) is o en used in a form of reverse-phase HÂ·PÂ·LÂ·C named for these structures. The third derivative of a linear function, such as conductivity, is zero at a concentration named for these structures, a value that is very high for CHAPS ("chaps") and very low for Tween 20. Reverse ones are described as "hairy." They form only below a packing parameter of one-third. Casein (KAY-sin) protein occurs naturally in one of these structures. A er these structures form at their namesake critical concentration and at the Kraf  temperature, detergents no longer affect surface tension since they start emulsifying. As the concentration of a phospholipid in water increases, it forms these structures, then liposomes, and then lipid bilayers. For 10 points, name these spherical aggregations of surfactant in solution.
