THE COAT MOISTURE AND STRENGTH PROPERTIES OF SOFT GELATIN CAPSULES WITH HYDROPHILIC VEHICLES
The paper deals with the determination of the mechanical characteristics of a gelatin coat under different drying conditions for further assessment of the stability of capsules with hydrophilic vehicles. When deformed, the soft gelatin coat shows the properties of a pliable body with an elastic range up to 10% strength and with a breaking elongation of 150-190%. To reduce the residual moisture of the coat increases its stiffness and strength limit.
