The outcomes indicated an existence of great compatibility among the alginate, organogels, and drug molecules. This may possibly be connected with all the powerful interactions (e.g., hydrogen bonding) amongst the components of the microparticles, recommended by the FTIR studies (18). Thermal Studies Figure 5a shows the thermograms of your organogel and developed microparticles. The thermogram of sunflower oilshowed an endothermic peak at 34 . The organogel showed a broad endothermic peak at 95 . This can be resulting from the combined impact of melting in the organogel and evaporation of water present within the organogel (18). BM showed an endothermic peak at 100 which may be attributed for the evaporation of the bound water associated with all the alginate. Even though dried microparticles had been utilized, the thermal profile suggested that it was not probable to eliminate the bound water fully. Equivalent observations have also been reported earlier (23). MSO and MOG have shown endothermic peaks at 60 . This endothermic peak may perhaps be linked with the heating of sunflower oil. In our earlier study, we have located that the gel to sol transition temperature ofTable III.

The shift with the endotherm to the higher temperatures might be attributed to the improved crystalline nature of your microparticles (as was evident in the X-ray diffraction (XRD) research). The endothermic peak of MOG was broader than that of MSO. This could be explained by the simultaneous evaporation in the water present within the organogel.
