On demand Webinar Series: Rheology for Pharmaceutical and Cosmetic Applications
Available at any time on demand until June 30, 2025.
Understanding the flow behavior and stability of pharmaceutical and cosmetic formulations is key to product performance and shelf life. In this two-part webinar series, we explore how rotational and oscillatory rheometry can be applied to extract meaningful data for product development and quality control.

Part 1: How to Measure Shear Viscosity Correctly
Rotational Rheometry to Characterize Flow Properties of Pharmaceutical and Cosmetic Products
Shear viscosity plays a crucial role in processing and application properties such as spreadability, pumpability, or injectability. In this webinar, we introduce the fundamentals of shear viscosity and how to determine it reliably using a rotational rheometer. From selecting the right temperature control system and geometry to establishing steady-state conditions for quality control, we’ll guide you through the most important steps and best practices. Real-world examples will show how to generate and interpret shear viscosity curves for different product types.

Part 2: How to Predict Shelf Life of Dispersions
Oscillatory Rheometry as a Useful Tool for Stability Forecast of Pharmaceutical and Cosmetic Products
Product stability over time is a critical factor in formulation development. This webinar focuses on oscillatory rheometry as insightful method to assess structural integrity and predict shelf life. You'll learn how to distinguish between solid- and liquid-like behavior, interpret viscoelastic properties, and apply both amplitude and frequency sweeps. We’ll explain how to determine cohesive energy DensityThe mass density is defined as the ratio between mass and volume. density and detect the onset of phase separation—two key parameters that influence long-term product stability.
Topics Covered:
- Viscoelastic behavior: Is your product more solid- or liquid-like?
- Rheometer operation principles and mathematical background
- Amplitude sweep: Determining cohesive energy DensityThe mass density is defined as the ratio between mass and volume. density
- Frequency sweep: Identifying the onset of phase separation
