As a result, the dynamic viscosities obtained from microrheology were in accordance with data from capillary viscosimetry. The DWS measurements revealed that all formulations had a clearly measurable storage modulus at frequencies >200 rad/s. Thus, all samples were low-viscous, while exhibiting non-Newtonian flow behavior. Obtained values of storage and loss modulus were then successfully correlated with the weight variability of capsules that were filled on a machine. In conclusion, the DWS technique enabled rheological analysis of self-emulsifying systems in a broad frequency range. The good data correlation with a capsule quality attribute was especially promising, since microrheological techniques are typically contact-free. Thus, they have a high potential in a quality by design framework of formulation development and production.
