Case study – R&D improvement study of dental product processing with instrumented micro-pilot technique

Sector : Pharmaceutics

Type : Group

Department : R&D / Industrialisation

The Client is facing issues with texture variabilites in industrialisation tests for dental product process while FDA certification in progress. RHEONIS is here to draw out the causes and influencing factors for such variabilities and recommend improvements of the process and any related aspect.

Combining industrial expertise and R&D special techniques

In such study, RHEONIS provides its industrial process expertise, its knowledge of DoE analysis and its special techniques for R&D with instrumented micro-pilots.

During this phase-segmented collaboration, we performed the following tasks :

  1. On site industrial process diagnosis during production
  2. Industrial Phenomenology analysis with respect to the DoE and its results
  3. Synthesis and recommendations for R&D study
  4. Design of special mixing tool for instrumented mixing micro-pilot on rheometry platform
  5. R&D study and conclusions on variability causes and influencing factors
  6. Synthesis and operational recommendations

Building an appropriate Design-Space and improving process

For a complex formula with dozen of ingredients, industrialisation trials are often constrained with economical limits.

Instrumented micro-pilot technique allows a fast, advanced and low-matter-consumption of ingredients impacts and processing (ingredient introduction and mixing speed/duration) in real-time sequences.

Various parameters can be monitored, so that critical steps can be clearly identified and their impact on product texture quantified.

Optimised processing conditions can thus be determined and effetcs such as hygrometry can be identified, allowing the building of an accurate design-space for parameters of interest.

Strengths of RHEONIS for pharmaceutical challenges

Quality By Design-oriented expertise

Low-matter consumption for product/process studies

Focus on phenomena and on-site diagnosis for DoE size reduction

Pragmatical approach for operational recommendations
