Formulasi dan Penentuan Nilai SPF Krim Tabir Surya Dari Ekstrak Daun Gedi (Abelmoschus manihot L.)

Abstract

Tabir surya merupakan sediaan kosmetik yang secara fisik atau kimiawi dapat menghambat penetrasi sinar UV. Efektivitas sediaan krim tabir surya berdasarkan nilai nilai Sun Protectting Factor (SPF). Tujuan dari penelitian ini untuk memformulasikan dan menentukan nilai SPF krim tabir surya ekstrak daun gedi ( Abelmoschus manihot L.) dengan konsentrasi 2,5, 5 dan 7,5%. Penelitian dimulai dengan ekstraksi sampel menggunakan metode maserasi. Ekstrak yang diperoleh kemudian diformulasikan dalam sediaan krim dengan cara pencampuran basis dengan ekstrak daun gedi. Krim ekstrak daun gedi selanjutnya dilakukan evaluasi dan uji nilai SPF secara in vitromenggunakan spektrofotometer UV-Vis. Hasil penelitian menunjukkan bahwa semakin tinggi konsentrasi ekstrak maka nilai sediaan SPF semakin tinggi dengan nilai yang diperoleh : 2,5% (11.922), 5% (23.172), 7,5% (33.384). Hasil evaluasi sediaan krim untuk organoleptis, homogenitas, pH, uji daya sebar memenuhi syarat sedangkan untuk uji daya lekat tidak memenuhi syarat.
