Potassium tetradecanoate, surfactants

They also studied the ternary phase diagram of the divalent surfactant dipotassium dodecylphosphate (K2D0P), monovalent surfactant potassium tetradecanoate (KTD) and D2O [155]. At 25 °C K2D0P exhibits L, (0-37% surfactant), I, (37-67%), H, (67-75%) and two phase liquid crystal/ hydrated surfactant crystal (75-100%). In the ternary system I cubic is seen between 20 and 60% K2D0P. Up to 30% KTD ean be incorporated into the phase at lower eon-... 

The x-ray scattering pattern of fluorinated surfactants differs from that of hydrocarbon-type surfactants. M band spacings have been observed for potassium tetradecanoate but not for ammonium salts of C7 and C9 perfluoroalkanoic acids (Fig. 7.1) [15]. Arrington and Patterson [15] explained the lack of M spacing by a higher electron density of the fluorocarbon chain.
