Abstract

The use of chemical-based mosquito repellents has excellent repellent power, but their use can cause hypersensitivity and irritation. In Indonesia, there are several plants that contain essential oils and have mosquito repellent effects. One of them is cosmos (Tagetes erecta L). Cosmos leaf extract is formulated into a lotion preparation so that it can adhere to the skin for a longer time, thus providing longer-lasting mosquito repellent properties. This research aims to determine the effect of varying cetyl alcohol concentrations on the physical properties of lotion. There are 3 lotion formulas used with cetyl alcohol concentrations of 2% (F1), 2.5% (F2), and 3% (F3). The research results show that F1 has a thick texture and brownish-yellow color, F2 has a thick texture and green color, and F3 has a very thick texture and green color. All formulas are homogeneous. F1, F2, and F3 had pH values of 7.5±0, 7.5±0, and 7.9±0, respectively. F1, F2, and F3 have respective viscosities of 20±0 dPas, 30±0 dPas, and 35±0 dPas. F1, F2, and F3 had spreadability values of 8.48±0.51 cm, 7.81±0.05 cm, and 7.10±0.37 cm, respectively. The conclusion of this study is that variations in cetyl alcohol concentration affect the texture, color, pH, viscosity, and spreadability of the lotion.
