Dispersion

Three types of polyglycerol-based dispersants are available: nonionic, anionic, and reactive types.
The nonionic type consists of polyglycerol as the hydrophilic group and alkyl chains of the lipophilic group, whereas the anionic type has a carboxyl group at the structural terminus.
By interacting with the surface of inorganic particles such as metal oxides, the anionic type can finely disperse nanoparticles in water and organic solvents.

By adding a dispersant, it enables to disperse to a range close to the primary particle size.

By adding a dispersant, coarse particles are reduced; thus, improvement in the transparency of the dispersion is expected.
