n-Octylpolyoxyethylene

n-Octylpolyoxyethylene is a nonionic surfactant that can dissolve membrane proteins and is used for protein solubilization, purification, and crystallization. Its critical micelle concentration (CMC) value is 6.6mM^{[1, 2]}. The CMC value is defined as the minimum concentration at which surfactant molecules in a solvent associate to form micelles^[3]. n-Octylpolyoxyethylene can be used as an antibacterial agent, possibly inhibiting bacterial growth by disrupting the bacterial cell membrane or interfering with the synthesis of proteins required for bacterial growth^[4].
