Uji Sifat Fisik Sediaan Hand Sanitizer Minyak Atsiri Serai Wangi (Cymbopogon nardus L.)
Hand sanitizer gel is easy to use, absorbs well and gives a cold sensation. Natural ingredient of citronella essential oil contains antibacterial agents that can be used in hand sanitizers. Gelling agents are components that affect physical properties of the preparation. The purpose of the study was to determine the physical properties of citronella essential oil hand sanitizer. The research method uses experimental research with posttest only design. The active substances are citronella essential oil and gelling agent use carbopol with concentration variations 0.5%; 0.75%; and 1.0%. Statistical data analysis with one way ANOVA and LSD to determine the difference in gelling agent concentration variation in the preparation. The research results of the organoleptic and homogeneous tests descriptively with the results of FI white colored, citronella scent, slightly thick consistency, FII white colored, citronella scent, thick consistency, FIII white colored, citronella scent, very thick consistency. All three formulas have a homogeneous homogeneity. The pH test results were FI (6.34±0.20), FII (5.74±0.10), and FIII (5.07±0.14) had a significant difference (sig0.05). The results of the spread diameter were FI (6.71±0.14), FII (5.95±0.21), and FIII (5.22±0.09) had a significant difference (sig0.05). The conclusion of the study showed that the results of the physical properties test of citronella essential oil hand sanitizer, including organoleptic, homogeneity, pH, and spread diameter meet the requirements.
