Microcrystalline Cellulose (MCC)

Microcrystalline cellulose (MCC) is a finely granulated crystalline substance, devoid of fibrous structures, and exhibits free-flowing properties. It remains insoluble in water, dilute acids, and most organic solvents, with slight solubility observed in 20% alkali solutions.

Derived from the depolymerization of cellulose, MCC is an odorless and tasteless crystalline powder obtained from natural cellulose sources. In pharmaceutical applications, MCC serves as a vital ingredient, functioning as both a pharmaceutical excipient and a disintegrating agent for tablets. Within the food industry, MCC serves as a fundamental component for functional foods, offering an advantageous health food additive profile. Its versatility extends to the paint industry, where its thixotropic and thickening properties are leveraged to serve as thickeners and emulsifiers in water-based coatings. Furthermore, in cosmetics, MCC plays multiple roles, acting as a filler, thickener, and emulsifier, with exceptional emulsifying capabilities for oily substances.

Pharmaceuticals Industries

MCC is mainly used as a binder in the pharmaceutical industry due to its outstanding dry-binding properties, enabling it to function effectively in direct compressionprocesses. As a binder, MCC is a crucial component in tablet formulation wet and natural compression processes. Critical aspects of MCC as a pharmaceutical binder include:

Functionality: As a binder, MCC can deform plastically under compression.
Critical Material Attributes: Excipients’ variability and impact on drug product performance must be
thoroughly understood. MCC’s potential CMAs are listed in the literature, which can help guide its use in
pharmaceutical formulations.
Direct Compression: MCC is commonly used in dry blend and dry granulation processes involving direct
compression.
Tabletability: MCC’s physicochemical properties play a significant role in tablet-ability, and understanding
these properties is essential for optimizing tablet formulations
