Formulation and Evaluation of Benzyl Benzoate Emulgel

The aim of the following research was to formulate benzyl benzoate in emulgel form and to evaluate the release of the medicament from it. Emulgel containing 25% w/w of benzyl benzoate was prepared by addition of a gelling agent; Carbopol 934 to an emulsion using Span 80 as emulsifying agent. The release of benzyl benzoate was determined by Franz diffusion cell using cellulose acetate membrane for a period of five hours at 32°C. Benzyl benzoate was analyzed by ultra-violet (UV) Spectrophotometer at 256 nm. The prepared formula of benzyl benzoate emulgel proved to be more efficient than other externally applied topical preparations as lotion, ointment and gel.
