This interpretation has been supported by both surface tension measurement for the liquid phase and fluorescence spectroscopy for bulk behaviour. From this study there is clear evidence that increasing the substitution rate from 10% to 35% induces a reinforcement of the hydrophobic interactions and thus the formation of more compact and stable aggregates which can complex hydrophobic compounds. The use of CMP 35% C8 could be envisaged in drug formulations where dispersion of a hydrophobic drug in an aqueous phase is required. 研究級經(jīng)典型橢偏儀 UVISEL
