FORMULASI LOTION REPELAN KOMBINASI MINYAK BUNGA KENANGA (2,5%,5% DAN 7,5%) DAN MINYAK NILAM 3% (Pengujian Karakteristik Fisika Kimia, Stabilitas dan Iritasi)

Background : Mosquito repellent is one of altenative repellent that not irritate respiration system because the application direct on the skin. One of substance had effect as a repellent (mosquito) is volatile oil. Plants that can produce volatile oil are cananga and patchouli. Objective : The purpose of this research to find the effect of consentration cananga oil (Canangium odoratum) 2,5%, 5%, 7,5% and patchouli oil (Pogostemon cablin) 3% to the physical chemistry characteristic, stability and irritation of repellent lotion. Method : The Methode used in this research is experimental method to compare 3 formulas with different consentration then analysis the characteristic physical chemistry, stability and irritation. Result and Conclusion : All the formula have same characteristic are white colour, typical aromatic smell, smooth texture and have emulsion type O/W. pH all formula respectively 7,23, 7,33 dan 7,16. Result of viscosity are 2266,67cPs ± 377,12 , 2133,33cPs ± 94,28 dan 1400cPs ± 163,30. While the result the power of spread are 0,32g/cm, 0,4067 g/cm dan 0,2618g/cm. The result for irritation test the showed that all formula not irritation when used. The conclusion of all the formula have the requirement
