Abstract

We report literature data indicating that the polyoxyethylene chain of polyoxyethylene detergents attracts cations via dipole-ion interactions thereby attaining a positive charge character. This implies that nonionic polyoxyethylene detergents like Triton X-100 and C12E8 may interact electrostatically with phospholipid head groups. We describe how a positive charge character of Triton X-100 and C12E8 can explain their hitherto mysterious stomatocytogenic shape altering effect in human erythrocytes.
