Formulation and Testing of Stick Deodorant Containing Bioactive Components from Molecularly Distilled Aceh Patchouli Oil

The presence of harmful chemicals used as active components of deodorants that are widely circulated in the market allows for adverse risks in long-term use, ranging from skin irritation to potential cancer. Aceh Patchouli oil, which has been distilled with molecular distillation technology, has 3 types, namely light fraction, heavy fraction and purified crude fraction, all of which contain high patchouli alcohol which is very useful as a natural antibacterial. Therefore, Aceh patchouli oil is used as the main active ingredient which is an innovation in deodorant formulation because it can be a safe bioactive component. The method used in this study is based on deodorant formulation experiments with the 3 types of the main active ingredient, each in 3 formulations with the amount of 10%, 15% and 20%. Tests are also carried out for deodorant preparations such as anti-bacterial tests, bacterial isolate that was used in this study is Staphylococcus aureus, which is incubated on Mueller-Hitton Agar media for 24 hours at 35-37°C using the Kirby-Bauer method. The result of deodorant test showed inhibition of Staphylococcus aureus bacteria by 7.29 -14.12 mm, higher than other products tested, which did not use bioactive patchouli oil. Each sample also did not show any risk of irritation such as itching, redness to festering. Formulated as a convenient homogeneous with a smooth surface stick deodorant, this deodorant utilizes a natural patchouli oil extract as the antibacterial source, eliminating concerns about skin darkening associated with some commercially available stick deodorants. Based on the results of the study, this deodorant formulation is highly recommended to be developed towards product commercialization, because it has a bacterial inhibition that is classified as very strong and safe for long-term use.
