Most suspending agents perform two functions i.e. besides acting as a suspending agent they also imparts viscosity to the solution. Suspending agents form film around particle and decrease interparticle
attraction.

A good suspension should have well developed
thixotropy. At rest the solution is sufficient viscous to prevent sedimentation and thus aggregation or caking of the particles. When agitation is applied the
viscosity is reduced and provide good flow characteristic from the mouth of bottle.
