Kurtis Patel | Why Ingredient Selection Shapes Manufacturing Outcomes

Ingredient selection is often treated as a formulation decision, but in manufacturing environments, it is fundamentally an operational one. The ingredients chosen at the beginning of product development influence not only performance and stability, but also how reliably a product can be produced at scale. According to Kurtis Patel, many downstream manufacturing challenges can be traced back to ingredient decisions that were made without fully considering real production conditions.

In early development, teams tend to evaluate ingredients based on functionality, label appeal, or availability. While these factors matter, they only represent part of the equation. Ingredients also have physical characteristics that affect how they behave during blending, encapsulation, compression, or filling. Density, particle size, moisture sensitivity, and flow properties all play a role in determining whether a formulation moves smoothly through equipment or introduces variability that must be managed later.

How Ingredient Behavior Changes at Scale

One of the most common misconceptions in product development is that performance in a small sample translates directly to performance in manufacturing. Kurtis Patel notes that many ingredients appear stable and manageable during bench testing, but behave very differently once exposed to larger batch sizes and continuous movement through equipment.

At scale, small differences become amplified. Ingredients with mismatched particle sizes may separate during blending. Hygroscopic materials may absorb moisture from the environment, affecting flow and stability. Fine powders may generate dust or cling to equipment surfaces, leading to inconsistent fills or weight variation. These behaviors are rarely visible in early testing but become obvious during production.

Understanding these dynamics early allows teams to adjust ingredient forms, sourcing specifications, or processing methods before problems appear. Without this evaluation, manufacturers are often forced to react to issues that could have been prevented.

Supplier Variability and Its Operational Impact

Ingredient selection is also closely tied to supplier consistency. Even when two ingredients share the same specification on paper, differences in sourcing, processing, or storage can lead to variation in performance. Kurtis Patel emphasizes that supplier variability is one of the most overlooked contributors to manufacturing inconsistency.

When development teams fail to account for this variability, they may design a process that works with one lot of material but struggles with the next. This creates challenges for quality teams and increases the likelihood of deviations or rework. By evaluating ingredients with supplier variation in mind, manufacturers can build more resilient processes that tolerate minor differences without sacrificing consistency.

This approach often includes tighter specifications, incoming material testing, and a clear understanding of how much variability the process can accommodate. Ingredient selection, in this context, becomes a decision about system stability rather than individual component performance.

Compatibility Between Ingredients

Another factor that shapes manufacturing outcomes is ingredient compatibility. Some ingredients interact in ways that affect flow, stability, or potency over time. These interactions may not be immediately obvious but can emerge during blending, storage, or compression.

Kurtis Patel highlights that compatibility issues often surface after production has already begun. Ingredients may bind together unexpectedly, alter moisture balance, or influence the behavior of other components in the formula. When compatibility is not evaluated early, teams may need to reformulate or introduce processing aids later in development.

Evaluating compatibility during ingredient selection helps teams identify potential conflicts and make informed adjustments. This may involve choosing alternative ingredient forms, adjusting ratios, or incorporating excipients that support stability and flow.

Manufacturing Method Matters

Ingredient behavior is also influenced by the manufacturing method itself. An ingredient that performs well in encapsulation may behave differently in tablet compression or powder filling. Kurtis Patel notes that ingredient selection should always be aligned with the intended production method.

For example, compressibility becomes critical in tableting, while flow and segregation are more prominent concerns in encapsulation. Ingredients that are ideal for one method may create challenges in another. Selecting ingredients without considering the manufacturing pathway can lead to inefficiencies or quality risks later on.

By aligning ingredient decisions with the production method early, teams reduce the likelihood of encountering unexpected constraints during scale-up.

Cost and Complexity Considerations

Ingredient selection also affects cost and operational complexity. Some ingredients may appear cost-effective at small volumes but introduce inefficiencies at scale due to handling requirements, processing steps, or yield losses. Kurtis Patel explains that these hidden costs often emerge only after production begins.

Ingredients that require special handling, extended blending times, or additional quality checks can slow down production and increase labor requirements. When these factors are not considered during development, they may compromise the economic viability of the product.

Evaluating ingredient selection through an operational lens helps teams understand the true cost of manufacturing, not just the cost of raw materials.

Why Early Evaluation Prevents Long-Term Issues

The common thread across these challenges is timing. Most manufacturing issues related to ingredients are easier to address early than late. Kurtis Patel emphasizes that early evaluation allows teams to make adjustments when flexibility is highest and costs are lowest.

When ingredient behavior, compatibility, and supplier variability are understood upfront, development teams can design processes that accommodate these realities. This reduces the need for reactive fixes and supports more predictable outcomes.

Ingredient selection, when treated as an operational decision, becomes a tool for risk reduction rather than a source of uncertainty.

Conclusion

Ingredient selection shapes manufacturing outcomes in ways that extend far beyond formulation goals. From flow and stability to supplier variability and production efficiency, the ingredients chosen early in development influence every stage of manufacturing. Kurtis Patel’s perspective underscores the importance of evaluating ingredients not only for what they do, but for how they behave.

By treating ingredient selection as a system-level decision, teams can build processes that are more resilient, scalable, and consistent. In manufacturing, predictability is built one decision at a time, and ingredient selection is one of the most influential choices a team can make.
