Microcrystalline Cellulose (MCC) stands out in the pharmaceutical industry not only for its role as a filler but also, and perhaps more significantly, for its exceptional properties as a binder. Its efficacy in binding powders together is a primary reason for its widespread use in tablet formulation, particularly in direct compression methods.

As a microcrystalline cellulose binder, MCC exhibits superior dry-binding properties. This means it can effectively cohere powdered ingredients into a solid, stable tablet without the need for granulation or the addition of wet binders. The mechanism behind this strong binding lies in MCC's ability to undergo plastic deformation under compression. When pressure is applied, MCC particles deform, creating a large surface area of contact. These surfaces form strong inter-particle bonds, primarily through hydrogen bonding and mechanical interlocking, resulting in tablets with high tensile strength and low friability.

The effectiveness of MCC as a binder is often quantified by its high dilution potential. This refers to the amount of active pharmaceutical ingredient (API) that MCC can successfully bind into a tablet. Even with challenging APIs that possess poor tableting properties, MCC can often facilitate successful tablet formation. This ability makes it a preferred excipient for formulators dealing with difficult-to-compress drugs.

Furthermore, MCC's binding capabilities are beneficial in wet granulation processes as well. While it excels in dry binding, its wicking action can also aid in the uniform distribution of the granulating fluid, contributing to the formation of well-formed granules that are amenable to drying and subsequent compression. In this context, MCC acts as a secondary binder, enhancing the overall cohesiveness of the granule.

The choice of MCC grade also influences its binding performance. Grades with finer particle sizes, like MCC 101, are often favored for their excellent compactibility, while grades with larger particle sizes, like MCC 102, can offer improved flow. However, both grades effectively serve as binders, contributing to the overall tabletability of the formulation.
