[Polymer-containing eyedrops. III. Surface tension of polymer solutions].
Therapeutical effect of ophthalmological solutions is markedly influenced by their surface tension which is also responsible for the irritating effect of the eye drop. Authors studied the effect of different polymers on surface tension. They found that each of the water soluble polymers studied decreased the surface tension of solutions against air. This surface tension decreasing effect is independent from the concentration of the solution. Its value is slightly influenced by the pH of the solution, while it is increased by its electrolyte content.
