Rheological properties testing of topical preparations for the skin

In the development process of skin external chemical generic drugs, due to the complexity of skin external preparations and the significant impact of production processes on the quality of the preparations, it is necessary to conduct sufficient research on the process steps and parameters that affect key quality attributes to ensure that the product achieves the same quality level as the reference preparations. The variable characteristics of key quality attributes (CQAs) in topical preparations for the skin. Comparative studies should be conducted on the rheological properties of imitations and reference formulations, including complete flow curves of shear stress and shear rate, yield stress and creep tests, and linear viscoelastic response. Germany NETZSCH high-performance rotational rheological system Kinexus Prime Ultra+, a high-performance research level rheological test platform, is used to measure the rheological properties of polymer melts, polymer solutions, suspensions, lotion, coatings, inks and food. It can characterize the molecular weight and molecular weight distribution of polymer materials, enabling rapid, simple, and effective quality testing and control of raw materials, intermediate products, and final products, helping users with raw material inspection, processing technology design, and product performance prediction.
