Abstract
A theological study of hydrophilic gels of Carbomer(R) 940 with tretin oin as the drug, and ascorbic acid as an antioxidant, has been carried out. At the same time, the effect of storage time has been determined . Both shear and compression deformations were applied. From the resul ts obtained, correlations between both types of deformation have been established. The results were statistically significant between shear and compression stresses, and between shear stress and area of spreadi ng.
