Development of technology of the soft medicinal form based on the extract of common hazel leaves

Abstract

Vascular diseases occupy an important place in the morbidity structure of the population of Azerbaijan. Varicose veins is the most spread pathology among them; it affects between 25% and 50% of the adult population of the country. The aim of the study was development of technology of the ointment containing Hazel thick extract. Methods. Physical and chemical methods were used for dispersion, density, emulsification rate, spreadability, and emulsion concentration determination. Results. The emulsifier concentration of 10% was selected in result of physical and chemical analysis. The oil phase dispersion degree depending on the № 1 emulsifier amount was shown using microscopy method. Thermal and colloidal stability of the ointment samples, as well as their spreadability was determined. It was found that the samples 3 and 4 are characterized by satisfactory spreadability indexes – 350 mm 2 , that is significantly differs from the samples № 1 (1005 mm 2 ) and № 2 (852 mm 2 ). Decrease in the emulsifier concentration below 10% leads to the emulsion instability. On the basis of the research results, rational emulsification conditions were selected. According to the microscopy analysis data and calculation of the emulsion concentration mixing time interval at 1500 rpm was investigated. Conclusion. The given research allowed developing of the composition and technology of the ointment containing common Hazel extract
