Control the variables that change ionic behavior
Confirm whether the grade is a liquid, powder, flake, pellet or blend and whether it requires melting, pre-dispersion or acid activation. Use controlled addition and adequate mixing without assuming that higher shear always improves the result.
Anionic surfactants and anionic polymers may form complexes with cationics. pH, concentration, salt, temperature and order of addition can affect haze, precipitation, viscosity and deposition. Screen changes one variable at a time and retain a clear batch record.
After bench preparation, run suitable stability, centrifuge, freeze-thaw, heat and packaging studies for the finished product. Ask about a specific grade or request technical documents.
