Many powders have the potential to cake during storage. As the strength of particle-particle interactions increases, especially via mechanisms involving moisture, the flow characteristics of the material are compromised, detrimentally impacting performance and value. Caking may be preventable or easily addressed through the adoption of well-defined protocols, for example, storing the material in a closely controlled environment, or periodically inducing flow through the use of low volume recycling loops.
In this webinar, Dr. Rajeev Dattani, Applications Specialist at Freeman Technology, will demonstrate the unique value of using dynamic powder testing for investigating the impact of caking. A particular focus is “crusting”, the heterogeneous development of caked material at the powder-air interface.
Experimental data illustrate the contrasting response of common excipients and ingredients, and demonstrate how appropriate testing can support the optimization of powder storage and associated handling.
