Solubility of dequalinium acetate (III) in water, ethanol, propylene glycol, and combination of these solvents was determined at 0°, 20°, 40°, and 60° by analytical method using ultraviolet absorption. Conductance of dequalinium salicylate (I), dequalinium chloride (II), and III was measured in water on a Wheatstone bridge, using cells with constants 0.3599. Its results showed that the salt (III) was more easily dissolved and dissociated in water than the salt I or II. The conductance of these salts, which was calculated by Onsagers equation and from our data, did not agree. It was considered that salt III was a strong electrolyte, and that salts I and II had a "co-solvency" effect.
