Effect Of Mixed Surfactant Ratio And Mixed Ratio Of Surfactant With Ylang (Cananga Odorata) Essential Oil On Microemulsion Characteristics As Body Mist

Abstract

This study aims to determine the effect of the formulation of the surfactant mixture ratio Tween 80: Tween 20: Span 80 on the characteristics of the microemulsion of ylang-ylang essential oil as a body mist, determine the appropriate ratio of the surfactant mixture of Tween 80: Tween 20: Span 80 on the characteristics of the best ylang-ylang essential oil microemulsion as a body mist, and determine the ratio of the mixture of surfactant and ylang essential oil microemulsion characteristics of the best ylang-ylang essential oil as a body mist. This study used a completely randomized design with a mixture ratio of three surfactants Tween 20, Tween 80, and Span 80. The treatments used were 97:2,75:0,25; 97:2,50:0,50; 97:2,25:0,75; 97:2.00:1.00; and 97:1,75:1,25. The best surfactant mixture ratio is the one with the smallest value. Data were analyzed using ANOVA, if there was a difference, the BNT test was continued. Treatment formulations the ratio of surfactant and ylang ylang essential oil was 90:10; 87.5:12.5; 85:15; 82.5:17.5; and 80:20. The best microemulsion is the one with the highest concentration of ylang-ylang essential oil and has a transparent appearance. The best microemulsion was tested for stability against pH and dilution for 8 weeks, observations were made every 2 weeks, and the damage rate was calculated using linear regression analysis. The results of this study indicate that the ratio of the surfactant mixture Tween 20: Tween 80: Span 80 has an effect on the microemulsion characteristics of ylang-ylang essential oil as a body mist. The ratio of surfactant mixture in RS1 (97: 2,75:  0.25) was the best treatment for making ylang-ylang essential oil microemulsion as a body mist with microemulsion characteristics that had a transparent appearance. The ratio of the mixture of surfactant and ylang essential oil in the SM4 treatment (82.5: 17.5) was the best treatment to make a microemulsion of ylang-ylang essential oil as a body mist with a turbidity index value (%) before and after centrifugation of 0.415 ± 0.098% and 0.248±0.053%, particle size 17.3±6.3 nm, the largest droplet size was 15.8 nm, a zeta potential value of 0.1mV and stable for 8 weeks of storage
