Formulasi Pembuatan Deodoran Spray dengan Variasi Konsentrasi Minyak Sereh Wangi dan Minyak Nilam

Abstract

Deodorant is a product used to eliminate body odor caused by bacterial activity in sweat. This research aimed to formulate a natural essential oil-based deodorant spray using citronella and patchouli oils and to evaluate the effects of oils concentration on deodorant spray quality, included antibacterial activity. This research used a Completely Randomized Design with two factors: citronella oil concentration (0.5%, 1.0%, 1.5%, and 2.0%) and patchouli oil concentration (0.25%, 0.50%, 0.75%, and 1.00%), resulting in 16 experimental units with two replications. The quality of deodorant spray was measured based on pH value, antibacterial activity, organoleptic tests (hedonic and descriptive), and irritation test. The results showed that concentration treatment of both essential oils had a similar pattern of decreasing pH and increasing antibacterial inhibitory power with increasing concentration used. The preference of spray deodorants was thought to be related to the appearing of the citronella oil aroma  intensity. The increasing of citronella oil concentration caused a decreasing in the intensity of the rose aroma. However, overall, panelists most preferred spray deodorants with a formulation of 1.5% citronella oil concentration, 0.25-1.0% patchouli oil and 2% rose oil. No significant effects were found in the irritation test, suggesting that this deodorant spray is safe for use. It can be concluded that the citronella and patchouli oil-based deodorant spray formulation has potential as a natural alternative to prevent body odor, with good antibacterial properties, a skin-compatible pH, and positive acceptance in the organoleptic test.
