|
Suspending method 1 Structure vehicle
|
are methylcellulose, sodium methyl cellulose, tragacanth, acacia, gelatin, carbomer, colloidal silicon dioxide and Veegum
|
|
|
Suspending method 2 Control floculation
|
use charged - viscosity - lyophilic (long chain high MW) agents to control floculated --> depend on vehicle (solvent)
|
|
|
suspension reasons
|
solubility - insatability - release profile - taste masking
|
|
|
Stock law V = d^2 (p_s - p_0)g / 18 viscostity
|
the slower the seditation speed the better
