Evaluation of Aloe weloensis (Aloeacea) Mucilages as a Pharmaceutical Suspending Agent

Table 4

Viscosity (poise) and flow rates (mL/sec) of ZnO suspensions prepared at different concentrations of Aloe weloensis mucilage, acacia, and NaCMC at room temperature.

Suspending agent	Concentration (%, w/v)	Flow rate	Viscosity
NaCMC	1	0.18	1.32
	2	0.12	1.47
	4	—	1.62
Acacia	1	1.25	0.81
	2	0.66	0.91
	4	0.4	0.95
Aloe weloensis mucilage	1	0.66	0.79
	2	0.4	0.84
	4	0.2	0.96

^—The suspension prepared from this suspending agent is too viscous that it cannot flow from the pipette.
