The rheological characterisation of microemulsions with the Rotational Rheometer RheolabQC gives essential information about their properties and the customer’s evaluation of the end product.

Microemulsions are often used as the base for gels and lotions in the pharmaceutical industry. Continuous quality control of these microemulsions is essential in order to achieve consistently high quality and long-term stability of the end product despite the often immense production volume.

The rheological behavior of microemulsions is controlled by adding different additives during the manufacturing process. Constantly checking rheological properties like the yield point, viscosity and thixotropic behavior guarantees a consistently high product quality. These measurements are also useful for product evaluation in the development department and are particularly important for the customer's evaluation of the end product.
