Rheological test methods provide a comprehensive toolbox for R&D, improving processability, and automated QC in the manufacture of cosmetics. Determine end-user satisfaction by managing easily accessible rheological parameters for texture, spreadability, flow behavior and other characteristics.
Rheological tests are used to establish ideal structure/property relationships. They can be even more revealing when used simultaneously with complementary analytical methods such as microscopy or molecular spectroscopy.
In R&D, rheological tests help reduce time needed for formulation development and so speed-up time to market. They can measure parameters during development which are relevant later for processability, so the measurements are fine-tuned by the time processing begins. The additional determination of elongational properties allows you to trouble shoot any filling process issues and to increase the productivity of filling lines.
Automated QC software routines easily fulfill standards of practice (SOPs) and requirements for reproducible, user-independent rheological measurements. Thermo Scientific instruments have tools and routines available to ensure correct sample loading, defined sample equilibration, well-standardized measuring procedures, automated evaluation including pass/fail assessment, and customizable documentation.
The Thermo Scientific HAAKE Viscotester iQ Rheometer is an ideal partner for rheological tasks in quality control. Whether it’s a quick, single point measurement for batch release or a more comprehensive rheological analysis of the final product, this compact, easy-to-operate Viscotester iQ rheometer will do the job.
The Thermo Scientific HAAKE MARS Rheometer is ideal for scientists and engineers who need extended testing of viscoelastic properties and tests requiring normal force capabilities.
Understand what to measure in your cosmetic formulation development and quality control, and which tools are best to do it. This collection of application notes and articles covers various aspects of optimizing final product properties and processing via rheological measurements.
