Formulation and Evaluation of Herbal Ultrasound Gel for Ultrasonography

This research paper provides the formulation idea of herbal ultrasound gel that is of good quality. In this formulation some available chemicals and natural ingredient were used which has no harmful effect to human skin. Chemicals that used were poly acrylic acid, sodium benzoate, glycerine, food grade color, tri-ethanolamine and natural ingredient is aloe vera extract which shows effective activity against allergic, irritation and inflammation problem due to its synergistic property. Firstly, aloe gel was extracted by ethanol extraction. Gel was formulated combining all ingredients. To justify the effectiveness of any formulation, results of evaluation tests are very important. For this, necessary physicochemical properties such as appearance, transparency, consistency, homogeneity, pH, thermal stability, conductivity, spreadability, viscosity etc. were evaluated. The results were satisfactory. No microbial growth was found during the incubation period for the prepared ultrasound gel. Also, no adverse effect to the human skin like irritation, allergy, inflammation etc. was observed. Ultrasound gel usually acts as a conductive medium and the conductivity result provides the information about the image quality. Conductivity of this formulated gel was 4.05 µS/cm. Using this formulated ultrasound gel during ultrasonography, clear image was found which was also of good quality. The overall results suggest that this formulation can be considered as successful and used with no harmful effect compared to the synthetic ones.
