Solutions of the nonionic amphiphile n-dodecyl octaoxyethylene glycol monoether (C12E8) in D2O and in salty H 2O have been investigated by static and dynamic light scattering. It is found that the micellar properties are little influenced by the choice of the solvent, whereas the critical properties (in particular, the critical exponents γ and ν) show a marked solvent effect. The interpretation of the observed critical behavior in terms of first-order correction-to-scaling contributions is discussed. © 1985 American Institute of Physics.

Abstract
Solutions of the nonionic amphiphile n-dodecyl octaoxyethylene glycol monoether (C12E8) in D2O and in salty H 2O have been investigated by static and dynamic light scattering. It is found that the micellar properties are little influenced by the choice of the solvent, whereas the critical properties (in particular, the critical exponents γ and ν) show a marked solvent effect. The interpretation of the observed critical behavior in terms of first-order correction-to-scaling contributions is discussed. © 1985 American Institute of Physics.
