Abstract


Abstract. Excessive exposure to free radicals can cause oxidative stress which can lead to various diseases such as skin cancer and photo-aging. Raspberry seed oil contains tocopherol compounds that have activity as an antioxidant that can neutralize free radicals. The purpose of this study is to determine the formula of microemulsion and microemulsion gel containing raspberry seed oil are good and physically stable. Microemulsion and microemulsion gel made with variations in the concentration of surfactant (tween 80), cosurfactant (glycerin), and a gelling agent (HPMC). Formulations microemulsion containing seed oil raspberries 5%, surfactant tween 80 35%, and cosurfactant glycerin 30% and microemulsion gel containing seed oil raspberries 5%, surfactant tween 80 35%, cosurfactant glycerine 30%, gelling agent HPMC 2% at a concentration of 5% , Microemulsion produces% transmittance 91.87% ± 4.71% and microemulsion gel 84.7% ± 4.92%. The results showed the microemulsion and microemulsion gel has good physical characteristics based on the test centrifuge, freeze thaw test, and physical stability test at 40 ° C for 28 days.

Abstrak. Paparan radikal bebas yang berlebihan dapat menyebabkan stress oksidatif yang dapat memicu terjadinya berbagai penyakit seperti kanker kulit dan photo aging. Minyak biji rasberi mengandung senyawa tokoferol yang mempunyai aktivitas sebagai antioksidan yang dapat menetralkan radikal bebas. Tujuan penelitian ini yaitu untuk mengetahui formula sediaan mikroemulsi dan mikroemulsi gel mengandung minyak biji rasberi yang baik dan stabil secara fisik. Sediaan mikroemulsi dan mikroemulsi gel dibuat dengan variasi konsentrasi surfaktan (tween 80), kosurfaktan (gliserin), dan gelling agent (HPMC). Formulasi mikroemulsi mengandung minyak biji rasberi 5%, surfaktan tween 80 35%, dan kosurfaktan gliserin 30 % dan mikroemulsi gel mengandung minyak biji rasberi 5%, surfaktan tween 80 35%,  kosurfaktan gliserin 30 %, gelling agent HPMC 2% pada konsentrasi 5%. Sediaan mikroemulsi menghasilkan % transmitan 91,87% ± 4,71% dan mikroemulsi gel 84,7% ± 4,92%. Hasil penelitian menunjukan sediaan mikroemulsi dan mikroemulsi gel memiliki karakteristik fisik yang baik berdasarkan uji sentrifugasi, uji freeze thaw, dan uji stabilitas fisik pada suhu 40°C selama 28 hari.
