SYLOID® FP silica’s unique, innovative design combines adsorption capacity, particle size, density, and internal surface area to provide multifunctional benefits or optimize an application. This helps minimize the number of excipients used and the complexity of formulations while expediting manufacturing, ultimately improving the efficacy of the final dosage form.

Feed rate and manifold pressure are two critical operating parameters that have the greatest impact on the final particle size. The goal is to achieve a consistent feed rate, as well as reduce blockages inside the mill so as not to starve or overfeed the milling chamber.

The first experiment evaluated whether the addition of different concentrations of SYLOID® mesoporous silica could prevent build-up inside a jet mill, using cholesterol as the active ingredient. Cholesterol was selected because it is a waxy, difficult to process solid, with many of the same physical properties as many complex small molecules currently under development. The results demonstrated that run time and yield both significantly improved with small additions of SYLOID® mesoporous silica, which would indicate similar positive outcomes for a difficult-to-micronize API.

Co-processing or co-jet milling is an approach that can help resolve some of the static and flow issues, making downstream blending and formulation easier. This involves adding a low percentage of a functional excipient to the micronization process – selecting one already found in downstream formulations can help simplify the process. 

The second experiment evaluated the impact of various percentage additions of SYLOID® 244 FP mesoporous silica on powder flow properties and static reduction, using acetaminophen and ibuprofen as model compounds. Testing was also conducted to evaluate the impact of pre-blended, post-blended or co-fed approaches.
