A stable multilamellar vesicle with an average diameter of ca 0.4 μ is formed from the HCO-10 concentration below 20 wt% whose phase shows a concentric lamella. The hydrophilic layer of the vesicle is more rigid than the hydrophobic core. The fluidity around the spin label 12NS incorporated in the HCO-10 vesicle significantly decreased with temperature; however, both spin labels 5NS and 16NS did not change significantly. The mechanism of fluidity change with temperature was discussed in terms of the dehydration of ethylene oxide and the breakdown of hydrogen bonding in the HCO-10 vesicle.
