Quaternary ammonium salts containing various anion : F-, CI-, Br-, I-, 1/2 SO4--, NO3-, H2PO4-, ClO4-, CH3COO-, CCl3COO-, C11H23COO-, 1/2 (COO-)2, _??_-COO- and CH3-_??_SO3- were obtained by the reaction of the corresponding amine salts with ethylene oxide. Their properties of surface tention, wettability, antistatic effect and the absorption by cotton, rayon, nylon, orlon, tetoron and wool were tested. By arranging the quaternary ammonium salts of hydrogen halide in the order of increase in absorption, the following result was obtained ; F-, Cl-, Br-, and I- in the order of magnitude of the power. And this ordering was commonly adapted to that of hygroscopic degree and wettability. This ordering supports Sexsmiths absorption mechanism (J. Colloid Science, 14, 598 (1959)) of cationic surfactants by cellulosic materials.
