Basil plants contain many compounds, one of which is terpenoids. Terpenoids can function as repellent. This study aims to determine the description of the physical quality of the basil leaf extract emulgel preparation (Ocimum sanctum L.) with variations in the concentration of viscolam 8%, 9%, 10% and Na CMC 4%, 5%, and 6%. This research is an experimental study conducted in the laboratory with samples of basil leaves obtained from Arso 4, Keerom Regency. The results of the organoleptic test for all formulas had the criteria of a cloudy green/brown color, a characteristic smell of basil leaves, and a thick form in F1, F2, F3 and very thick in F4, F5, F6. While the average pH for all formulas is 6, and the six formulas are not homogeneous seen by macroscopic and microscopic methods, and the six formulas have a dispersion that meets the requirements. Furthermore, for the adhesion test F1 and F2 showed results that did not meet the requirements with a value of less than 4 seconds but F3, F4, F5 and F6 showed results that met the requirements of more than 4 seconds and the emulsion type test where all formulas had an O/W type, and in F3 the O/W type is clearly visible compared to other formulas. From the results of the study, it can be concluded that F3 with 10% viscolam concentration met the requirements because the organoleptic tests, pH, spreadability, adhesion and emulsion type had the best results.
