Toothpaste Rheology Additives · MCC / MC
What Is MCC / MC?
MCC / MC (Microcrystalline Cellulose / Microcrystalline Cellulose co-processed) is a specialized rheology additive within LANDU's dedicated Toothpaste Rheology Additives category — engineered for premium oral care systems that demand strong structural support, controlled rheology, and long-term paste stability.
Unlike general-purpose cellulose derivatives, MCC / MC is purpose-built for one of the most technically demanding daily chemical systems. Public technical literature and patents confirm that microcrystalline cellulose — especially in colloidal form co-processed with sodium carboxymethylcellulose (MCC/CMC) — significantly improves structure, suspension, shear-thinning behavior, and overall system stability. Rudraraju et al., 2005 WO2004071322A2
On this website, MCC / MC is presented as a focused product direction within the Toothpaste Rheology Additives family — not a footnote under general cellulose ether — reflecting LANDU's deep oral care formulation expertise.
Why It Matters
Why MCC / MC Matters in Toothpaste Formulations
Toothpaste is a complex structured system. A finished product must deliver stable paste body during storage, controlled flow under brushing pressure, consistent dispensing, excellent suspension of abrasives and actives, and a smooth user experience from production to end-use.
Dedicated toothpaste rheology additives like MCC / MC address these needs precisely — delivering structural reinforcement, consistency control, system stabilization, and improved formulation balance. General-purpose thickeners address only part of this picture.
This is why LANDU positions MCC / MC as a standalone product direction within a dedicated oral care category — helping brands create premium, differentiated toothpaste products that meet the technical and clean-label expectations of the 2026 oral care market. COSMILE Europe INCI

Key Product Benefits of MCC / MC
Structural Support
Builds and maintains robust toothpaste paste structure, providing body and preventing slumping or phase separation — ensuring the product holds its form from tube filling through to end-use.
Rheology Control
Delivers pseudoplastic and shear-thinning behavior for easy dispensing and pleasant brushing feel. The paste flows freely under squeezing pressure and recovers its structure immediately at rest. Rudraraju et al., 2005
Stability Improvement
Functions as a bulking, absorbent, and emulsion-stabilizing agent, enhancing long-term system stability and suspension of solids — reducing settling of abrasives and active ingredients throughout shelf life. COSMILE Europe INCI
Better Dispersion Logic
When co-processed with CMC, the hydrocolloid acts as a protective colloid — improving dispersion and forming a thixotropic network ideal for structured oral care formulations. WO2004071322A2
Stronger Oral Care Differentiation
Positioned under LANDU's dedicated Toothpaste Rheology Additives family, MCC / MC helps your oral care portfolio stand out as technically advanced and application-specific — clearly beyond what general cellulose ether suppliers offer.
Clean-Label & Sustainability Ready
Derived from renewable wood pulp, MCC / MC is biodegradable and biocompatible — aligning with 2026 clean beauty and sustainable oral care trends without compromising technical performance.
Science & Mechanism
How MCC / MC Works — Mechanism of Action
MCC consists of insoluble microcrystalline particles that, when co-processed with a small amount of sodium carboxymethylcellulose (CMC), form a thixotropic three-dimensional gel network upon proper hydration and shear. Rudraraju et al., 2005
At Rest → Yield Stress & High Viscosity
The three-dimensional colloidal network creates measurable yield stress and high viscosity — stabilizing abrasives and active ingredients, preventing settling, and maintaining paste body integrity during storage and transport.
Under Shear → Strong Shear-Thinning
When squeezed or brushed, the network temporarily breaks down — producing strong pseudoplastic (shear-thinning) behavior for easy extrusion from the tube and smooth, effortless brushing. No lumping, no resistance. Rudraraju et al., 2005
After Shear → Rapid Structure Recovery
Once shear stops, the network quickly reforms — restoring structure, preventing settling, and maintaining the clean ribbon shape on the brush. This thixotropic recovery is a defining advantage of colloidal MCC/CMC systems. WO2004071322A2
Key Insight: This unique colloidal behavior makes MCC / MC particularly effective in toothpaste for paste "stand-up", suspension stability, and consistent sensory performance — benefits that are difficult to replicate with conventional CMC alone.
Peer-Reviewed Evidence
Scientific Backing
Recent studies and patents provide strong technical validation for using MCC / MC in rheology-modified oral care systems. These findings confirm MCC / MC belongs to an advanced structure-support and rheology layer for structured toothpaste formulations.

Int. J. Pharmaceutics · 2005
Extreme Shear-Thinning & Thixotropic Behavior
Rudraraju et al. demonstrated that colloidal MCC/NaCMC gels exhibit extreme shear-thinning and thixotropic behavior with measurable yield stress that builds over time and remains stable for months — directly validating the structural network mechanism in toothpaste-relevant systems.

Co-Binder in Toothpaste: Stability, Stringiness & Flavor
Colloidal microcrystalline cellulose co-processed with hydrocolloids (MCC/CMC) is used as a co-binder in toothpaste to reduce stringiness, improve stability, and enhance flavor release while maintaining excellent suspension — confirming direct oral care applicability.
