Sintesis asam 9,10-dihidroksi stearat (DHSA) dari asam oleat terepoksidasi merupakan salah satu upaya yang akan meningkatkan penggunaan, diversifikasi dan nilai tambah minyak kelapa sawit. Scaling up proses epoksidasi asam oleat dari skala laboratorium ke bench scale (kapasitas 5 L) terjadi perubahan volume dan geometri dari peralatan yang akan mempengaruhi proses epoksidasi itu sendiri sehingga perlu dilakukan observasi terhadap parameter-parameter yang akan digunakan dalam basic dan engineering design. Tujuan dari penelitian ini adalah melakukan scaling up proses konsistensi dari skala laboratorium ke bench scale (kap. 5 L) epoksidasi asam oleat sebagai produk antara sintesis DHSA dalam pengembangan produk turunan kelapa sawit yang akan digunakan sebagai bahan kosmetik. Scaling Up epoksidasi asam oleat dengan asam performat yang dibentuk secara in situ dilakukan menggunakan reaktor 5 liter dengan perbandingan mol asam oleat : asam format : hidrogen peroksida 50% = 1 : 1,25 : 6. Produk epoksidasi ini akan dilanjutkan untuk dihidroksilasi pada sintesis DHSA sebagai bahan kosmetik.
