In the pharmaceutical and nutraceutical industries, the tableting press is where the magic happens—but it’s also where many headaches begin. From capping and sticking to low hardness, production issues can lead to expensive downtime and wasted raw materials.

At SenoinfiTech, we’ve analyzed thousands of formulation failures. More often than not, the secret to a smooth production run lies in the quality and type of Microcrystalline Cellulose (MCC) used.

1. The “Capping” Crisis

The Problem: The top of the tablet separates from the main body during or after ejection. The Cause: Often caused by air entrapment or poor particle bonding. The SenoinfiTech Solution: Our MCC PH102 and PH200 grades feature a porous structure that allows for better air escape during compression. Their high plastic deformation ensures a strong “interlocking” bond between particles, significantly reducing the risk of capping.

2. Sticking and Picking

The Problem: Formulation material adheres to the punch faces, resulting in defective tablet surfaces. The Cause: High moisture content in the excipients or poor lubrication. The SenoinfiTech Solution: We maintain a strictly controlled moisture level (typically <5%) in our standard grades. For moisture-sensitive APIs, SenoinfiTech’s Low-Moisture MCC acts as a “moisture scavenger,” keeping the powder dry and free-flowing, which prevents the “tackiness” that leads to sticking.

3. Tablets That Won’t Break Down (Disintegration Issues)

The Problem: The tablet is hard enough, but it fails the USP disintegration test, meaning it won’t release the active ingredient in the body. The Cause: Over-compression or using the wrong type of binder. The SenoinfiTech Solution: MCC is a unique excipient because it acts as both a binder and a disintegrant. Due to its capillary action, SenoinfiTech MCC rapidly pulls water into the tablet, causing it to swell and burst from the inside out. This ensures that even the hardest tablets maintain an optimal release profile.

4. Weight Variation

The Problem: Tablets coming off the press have inconsistent weights, leading to dosage inaccuracy. The Cause: Poor flowability from the hopper into the die. The SenoinfiTech Solution: Flow is all about particle shape and size distribution. We eliminate the “fines” (excessive dust) that cause bridging and clogging. By using SenoinfiTech’s Direct Compression grades, you ensure a consistent, gravity-fed flow that keeps tablet weights within tight tolerances.

Optimize Your Press with SenoinfiTech

Don’t let production flaws derail your schedule. Choosing the right MCC is about more than just filling a capsule; it’s about engineering a reliable manufacturing process.

Common Troubleshooting Checklist:

• Is your tablet too soft? Try increasing the ratio of SenoinfiTech PH101.

• Is your powder flowing unevenly? Switch to SenoinfiTech PH102 or PH200.

• Is your API moisture-sensitive? Ask for our Low-Moisture (LM) series.
