Microcrystalline Cellulose + Carboxymethyl Cellulose (MCC + CMC)

Microcrystalline Cellulose + Carboxymethyl Cellulose (MCC + CMC)

CMC RC Grade is a blend of Microcrystalline Cellulose (MCC) and Sodium Carboxymethyl Cellulose (CMC), offering enhanced suspension, emulsification, and stabilization properties. It prevents sedimentation in liquids, ensures uniformity, and improves emulsion stability. In creams and lotions, it acts as a thickener with opacifying properties, enhancing texture and appearance. Ideal for pharmaceutical and cosmetic formulations, it ensures optimal stability and performance.

Chemical Name and CAS Registry Number :-9004-34-6 (Microcrystalline Cellulose), 9004-32-4 (Sodium Carboxymethyl Cellulose)
Functional Category :-Stabilizing agent; suspending agent; tablet and capsule disintegrant; viscosity-increasing agent; water-absorbing agent.

Applications in Pharmaceutical Formulation & Technology

MCC + CMC grades enhance suspension stability, act as emulsifiers, and function as thickeners in pharmaceuticals and food products. They prevent sedimentation in syrups, antacids, sprays, gels, and emulsions, ensuring uniformity. In the food industry, they improve texture and stability in dairy, beverages, sauces, and bakery items. Additionally, they enhance the consistency of lotions, creams, and topical formulations.
