Films	SEM	Hard capsule sample	Disintegration test (DT) minutes
GF		Hard capsule cannot be dipped from the solution.	DT was not conducted due to hard capsule of this formulation was not able to be produced.
GC33			5.31 ± 0.22
GC50			6.59 ± 0.60
GC67			7.30 ± 0.88
CF		Hard capsule cannot be dipped from the solution	DT was not conducted due to hard capsule of this formulation was not able to be produced.

DT values are presented as mean values ± standard deviation with P-value is 0.0493.
