Lattice® NTC-61 is a water-dispersible grade of microcrystalline cellulose (MCC) powder used as a suspension aid and emulsion stabilizing agent.
Lattice® NTC-61 is a microcrystalline cellulose (MCC) powder processed to include carboxymethylcellulose. Adding a water-soluble hydrocolloid like carboxymethylcellulose to MCC makes Lattice® NTC-61 a "colloidal" MCC, which is easier to disperse in water than standard MCC.
When fully dispersed in water, Lattice® NTC-61 forms a 3D gel network that is stable over a wide range of pH and temperatures. This network is effective in encapsulating and stabilizing water-insoluble particles within the dispersion. Thus, Lattice® NTC-61 is often used in several types of water-based formulations as a stabilizing agent for suspensions and emulsions. For example, Lattice® NTC-61 is used in agrochemical suspension concentrates to improve stability and shelf life by preventing aggregation and crystallization of active ingredients. Lattice® NTC-61 may also be used in inks to improve stability and homogeneity in formulations based on emulsions.
Lattice® NTC-61 requires a low level of shear to be activated compared to Lattice® NTC-80 and is best suited for low-viscosity suspensions. For more information on how to disperse and activate Lattice® NTC-61, check out this content.
