How to disperse and stabilize pigments

 · Grinding The described particles can be prepared in a method comprising the steps of dispersing a therapeutic or diagnostic agent in a liquid dispersion medium and applying mechanical means in the presence of grinding media to reduce the particle size of the ... · Patent number: Abstract: A process for replacing the continuous phase of a nanoparticle dispersion with a less polar phase, includes filtering the dispersion through a semi-permeable membrane filter to remove the continuous phase, and introducing a less polar phase.Grinding stage: Through mechanical energy (impact and shear forces), the pigment agglomerates are broken up and disrupted into smaller units and dispersed (uniformly distributed). Stabilization of pigment suspension : The pigment dispersion is stabilized by dispersing agents in order to prevent the formation of uncontrolled flocculates.

 · A nanoparticle dispersion of Danazol was prepared using 1 mm diameter glass grinding media (0.85-1.18 mm from Potters Industries). A cylindrical glass vessel having a diameter of 2.75 inches (7.0 cm) with a volume of 400 ml was charged with 212 ml of unleaded glass grinding media.Wet grinding can take place in any suitable dispersion mill, including, for example, a ball mill, an attritor mill, a vibratory mill, and media mills such as a sand mill and a bead mill. A media mill is preferred due to the relatively shorter milling time required to provide the intended result, i.e., the desired reduction in …In one embodiment, the lignin nanoparticle dispersion and/or derivatized lignin nanoparticle dispersion (as described above) are added to the water dispersible and/or water soluble polymer at a weight ratio in the range of from about 0.1:99.9 to about 99.9:0.1 lignin.
