✦ Synopsis
The viscosity of salicylic acid--cetrimide systems was altered in the presence of sodium salts. The viscosity variation was associated with the degree of salicylic acid saturation of the surfactant solution and apparcntl} not with the pH o l t h e system. The increase in viscosity was probably due to formation of sodium salicylatc by a reaction of the bodium additive with the acid and the interaction of this salicylate with the free cetrimide molecules in the system. The decrease in viscosity was attributed to the nonavailability of these surfactant moleculcs.

Various additives were added to the gel-like product which results from the interaction of salicylic acid with cetrimide. The additives were alcohols, acetone, water, glycerin, propylene glycol, polyethylene glycols, amyl acetate, heptane, hexadecane, dioxane, cyclohexane, benzene, methylbenzene, et
The viscosity and surface tension of systems containing small amounts of salicylic acid in aqueous solutions of cetrimide were determined. An abrupt increase in viscosity was observed, and the molar ratio of salicylic acid to certrimide at which this viscosity increase occurred was 1:2. The surface
