The solubilization and viscosity of polyoxyethylene dodecyl ether (PODE) solutions were studied as a function of the polyoxyethylene chain-length (<I>p</I>). The solubilization is in accordance with the isotherm <I>S</I>=<I>Kc<SUP>n</SUP></I>, where <I>S</I> is the extent of solubilization, <I>c</I>, the concentration of detergent, and <I>n</I> and <I>K</I>, constants. The value of <I>n</I> increases with the <I>p</I> value and is slightly greater than unity for PODE of <I>p</I>>27. The <I>K</I>′-value calculated from Huggins' equation, which is dependent on the <I>p</I> value, decreases at first with the <I>p</I> value and then somewhat increases in spite of the increasingly hydrophilic nature. The effective volume, Φ⁄<I>c</I>, of PODE, which is nearly independent of <I>c</I> except for the case of PODE in which <I>p</I>=7.6, increases regularly as the <I>p</I> value becomes larger. On the basis of these results, the polymer-like property of PODE of a considerably large <I>p</I> value and the interaction among aggregates of PODE were discussed in connection with ultracentrifugal data reported previously.
