PENGEMBANGAN FORMULASI MIKROEMULSI MINYAK SEREH (Cymbopogon nardus) MENGGUNAKAN EMULGATOR SURFAKTAN NONIONIK

Abstract

Citronella oil (Cymbopogon nardus) is an essential oil which useful as an antibacterial that is usually provided in the form of macroemulsion for topical use. absorption of macroemulsion through the skin relatively low, thermodynamically is not stable and can produce a separate phase in the storage period. The one of development emulsion system to get better characteristics is to form a microemulsion. Microemulsion is an oil and water dispersion stable thermodynamically stabilized by surfactants and in some cases a cosurfactant. The objective of this study was to formulatecitronella oil in the form of a stable microemulsion using nonionic surfactant. Optimization of the type and amount of emulsifier (surfactant) was required to formulate a stable microemulsion. In this study, microemulsion was evaluated during a month. Type and concentration of surfactant, cosurfactant, Citronella oil (Cymbopogon nardus) and water was optimized. A stable citronella oil microemulsion was successfully created with composition of 15% PEG 400 as cosurfactant, 15% tween 80 as surfactant, 2-4% Citronella oil as oil phase and 10% glycerin as humectant and distilled water as aqueous phase. From the observation, microemulsion formula has clear appearance but physically unstable during a month storage.

“…According to Marques et al (2018), a fluid with this rheology has a velocity gradient that is perpendicular to the shear stress and a linearly proportional shear stress. These findings demonstrated that the preparation resembles a solution or liquid that flows readily since the droplets generated were smaller than emulsion (Hasrawati et al, 2016).…”

Sintesis Mikroemulsi Menggunakan Surfaktan dan Minyak Atsiri Kulit Buah Jeruk Manis (Citrus sinensis) Sebagai Body Mist

“…Surfaktan nonionik mempunyai toksitas relatif rendah dan memiliki masing-masing nilai Hydrophilic Lipophilic Balance (HLB) tinggi, medium dan rendah (Suhendra et al, 2012). Hasrawati et al (2016) melaporkan bahwa penggunaan surfaktan nonionik pada pembuatan mikroemulsi relatif aman karena memiliki toksisitas dan sifat mengiritasinya rendah. Penggunaan tiga surfaktan dengan nilai HLB yang berbeda dapat membentuk mikroemulsi yang lebih stabil dibandingkan dengan dua campuran surfaktan atau hanya satu surfaktan (Sucitawati et al, 2021).…”

Physical Stability of Sea Buckthorn Oil Nanoemulsion with Tween 80 Variations

“…Jika sistem pada sediaan memiliki ukuran partikel sangat kecil ketika dilewati cahaya, maka berkas cahaya akan diteruskan, sehingga warna larutan pada sediaan akan terlihat transparan dan hasil nilai persen transmitan akan semakin besar 21 . Dalam pengujiannya, aquadest digunakan sebagai blanko atau pembanding dikarenakan aquadest tidak memiliki partikel yang dapat menahan transmisi cahaya sehingga cahaya yang dilewatinya akan diteruskan tanpa adanya efek penghamburan cahaya, oleh karenanya aquadest memiliki nilai persen transmitan 100% 22 .…”
