“…Microemulsion testing against heating is the most critical test. High temperature causes dehydration increase in the hydrophilic part so that the emulsifier molecules aggregate and the solution became cloudy (Indirasvari et al, 2018).The result of this study showed that all formulations were able to produced stable microemulsions due to turbidity index value less than 1%, transparent appearance and no separation. The best treatment in first stage is the S3 formula (98:0, 5:1, 5) because it has the lowest average turbidity, so it is continued in the second stage research.…”

Clove leaf essential oil is a volatile compound, unstable to heat, light and air. Clove leaf essential oil can be prepared in microemulsion (o/w) preparations to maintain stability and aplicable in food. The purpose of this study was to obtain a microemulsion formulation of clove leaf essential oil (o/w) with good stability. The nonionic surfactants used consisted of Tween 20, Span 80 and Tween 80. This research was carried out in 2 stages. The first stage consisted of a mixture of surfactant ratios (Tween 20, Span 80 and Tween 80) with 5 treatment levels, namely (98:2:0), (98:0:2), (98:0,5:1.5), (98:1,5:0,5), and (98:1:1). The second stage consisted of the ratio of clove leaf essential oil and the ratio of surfactants selected in the first stage which consisted of 8 levels, namely (15:85), (17.5:82,5), (20:80), (22.5: 77.5), (25:75), (27.5:72,5), (30:70), and (32.5:67,5). Stability test was carried out on centrifugation force, heating, pH, and dilution with turbidity index parameters. The turbidity index value was below 1% and the transparent appearance was declared as a stable microemulsion. The results showed that the ratio of the mixture of nonionic surfactants (98: 0.5: 1.5) was the best result with the characteristic turbidity index value before testing 0.181±0.007%, after centrifugation 0.188±0.004% and after heating 0.215±0.013%. Meanwhile, the ratio of clove leaf essential oil to surfactant 22.5:77.5 was the best result with a transparent appearance, the turbidity index value before testing was 0.214±0.013%, after centrifugation was 0.225±0.013% and after heating was 0.268±0.012%. The clove essential oil microemulsion was stable at pH (3.5; 4.5; 5.5) and dilution (1:1, 1:9, 1:99). The size of the clove leaf essential oil microemulsion droplets formed 2 peaks, namely peak 1 of 93% with an average size of 35.4 nm and peak 2 of 7% with an average size of 2759.3 nm with a polydispersity index value of 0.420. The clove essential oil microemulsion had an average zeta potential value of 0.1 mV. Clove leaf essential oil was stable for 8 weeks of storage.

“…Pada pH 4,5, pH 5,5 dan pH 6,5 mikroemulsi minyak atsiri cempaka putih masih stabil yaitu memiliki nilai indeks turbiditas kurang dari 1% dan kenampakan transparan. Indirasvari et al (2018) melaporkan derajat keasaman (pH) pada pH 3,5 dan pH 4,5 tidak berpengaruh terhadap mikroemulsi VCO. Surfaktan non ionik digunakan dalam pembuatan mikroemulsi VCO, sehingga bagian hidrofilik surfaktan tidak terdisosiasi oleh pengaruh…”

Essential oils are complex mixtures of volatile alcohol compounds and are produced as secondary metabolites in plants. Essential oils usually determine the characteristic aroma of the plant, white cempaka flowers contain 0.2 % essential oil obtained by distillation. The essential oil contained in white cempaka is shown to have antimicrobial activity. This study aims to determine the effect of the formulation of the ratio of the surfactant mixture Tween 80: Tween 20: Span 80 on the microemulsion characteristics of white cempaka essential oil as a body mist, determine the ratio of the surfactant mixture Tween 80 : Tween 20: Span 80 appropriately to obtain the microemulsion characteristics of white cempaka essential oil as a body mist, knowing the effect of the ratio of the mixture of surfactants and essential oil of white cempaka on the microemulsion characteristics of white cempaka essential oil as a body mist and determining the appropriate ratio of the mixture of white cempaka and essential oil to obtain the microemulsion characteristics of white cempaka essential oil as body mist .

“…Hal ini disebabkan oleh Tween 80 dan Span 80 dapat mengemulsi senyawa bioaktif yang terlarut pada ekstrak bunga kenikir, dimana senyawa bioaktif bunga kenikir umumnya bersifat non polar (Cahyana et al, 2021). Indirasvari et al (2018) menyatakan bahwa surfaktan dengan HLB 13 tetap stabil pada senyawa non polar. Jumlah rendemen yang diperoleh juga berhubungan dengan kadar air enkapsulat, dimana kadar air bahan yang tinggi menyebabkan rendemen yang diperoleh rendah akibat terjadi penguapan pada saat proses pemanasan.…”

“…Span 80 (HLB = 4,3) bersifat hidrofobik kemungkinan berada dibagian dalam yang terdiri dari sorbitol terester sebagian dengan mono dan dianhidrida asam oleat, sedangkan Tween 80 (HLB = 15) kemungkinan berada dibagian luar yang terdiri dari sorbitan polioksilat dan asam oleat. Gugus hidrofiliknya adalah polieter yang disebut juga gugus polioksietilen (polimer dari etilen oksida) (Indirasvari et al, 2018).…”

“…Hal ini terjadi karena penambahan Tween 80 dapat membuat proses pengeringan lebih cepat, sehingga mampu mencegah terjadi pencoklatan (browning), sedangkan Span 80 merupakan surfaktan non polar yang dapat mengikat senyawa non polar seperti karotenoid yang berkontribusi terhadap warna bunga kenikir, sehingga tetap stabil pada saat pemanasan berlangsung. Pendapat lain dikemukakan oleh Indirasvari et al (2018) bahwa HLB 13 membuat mikroemulsi tetap stabil, hal ini disebabkan selain memiliki gugus polar dan non-polar dalam molekulnya, surfaktan juga memiliki kemampuan untuk menurunkan tegangan permukaan. Tegangan permukaan yang rendah mikroemulsi yang dihasilkan akan lebih stabil.…”

The study aimed to know the effect of the combination of tween 80 and span 80 on the encapsulating characteristics of kenikir flower dye extract and determine the best combination of tween 80 and span 80 to produce encapsulated kenikir flower dye extract. This study using a simple Group Randomized Design with a combination treatment of tween 80 with span 80, to archive HLB values of 8, 9, 10, 11, 12, and 13. Each treatment is carried out 3 times so that 18 units are obtained. The data obtained is analyzed with variety analysis and if there is an effect of treatment on the observed variables, then continued with Tukey.
