  • Various benchmark tests are used to qualify hypromellose: Viscosity Degree of substitution (DS) Molar substitution (MS) Salt content Moisture Because hypromellose solution is a non-newtonian solution and exhibits pseudoplastic, more specifically, thixotropic behavior, various test methods are available, and the results of different methods and viscosmeters do not necessarily correspond to each other.
