Abstract

Transparent soap has a transparent and shinier appearance and is able to produce a softer foam on the skin. The appearance of transparent soap is attractive, classy and luxurious besides that, transparent soap can also be used as souvenirs, souvenirs so that it gives a unique impression and exclusive look. Basil plant (Ociumum basillicum L) is one of the plants that has antibacterial activity. This study aims to formulate and evaluate transparent solid soap from basil essential oil. The research began by formulating transparent solid soap preparations with varying concentrations of basil essential oil, namely F1 (as control), F2 (2%), F3 (4%), F4 (6%). All formulas were evaluated and tested for physical stability consisting of organoleptic test, foam stability test, cycling stability test, and other additional tests such as pH test, moisture content test, and irritation test. The results showed that all formulas had similarities but differed in F1 as a control that had an olive oil odor. Foam stability test showed F3 and F4 which had the best average percentage of stability compared to F1 and F2 when exposed to cycling test temperatures. In the pH test F2 has a pH of 9, F3 pH 10, and F4 pH 11. In the water content test F2 has a water content value of 1.13%, F3 1.10% and F4 1.02%. And in the irritation test, both F1, F2, F3 and F4 did not cause irritation to the skin such as redness or itching and peeling. © 2025 Author(s).
