PENGEMBANGAN FORMULA KRIM MINYAK SEREH (Cymbopogon citratus) SEBAGAI ANTI NYAMUK TOPIKAL

Abstract

Volatile oils extracted by steam distillation from Cymbopogon citratus were formulated in creams. The
essential oils were then employed as active ingredients in the preparation of insect repellents used in our field trials.
These creams containing 0%; 0,5%; 1%; 5%; 10% and 15% (w/w) of volatile oil from Cymbopogon citratus. These
creams were evaluated in physical qualities like appearance, pH, spreadibility, and viscosity. And also were
evaluated for their repellency effect against adult female mosquitoes of Aedes aegypti. Results from the field trials
indicate that cream containing 10% of the essential oil from Cymbopogon citratus provided 1071 ± 26.514 seconds of
protection time against mosquito bites. And the cream containing 15% of the essential oil from Cymbopogon
citratus provided 1097.333 ± 19.139 seconds. It means cream containing 15% of the essential oil is the best formula of
repellent cream, but does not significantly with cream containing 10 % of the essential oil
