Abstract

Loss of moisture in the skin and exposure to high UV rays can cause dry, thin, inelastic skin and wrinkles. Proper anti-aging cream can reduce and prevent skin damage. Moringa leaf extract and cananga oil have specific bioactive properties such as antioxidants and antibacterials. Meanwhile, lemon oil is high in vitamin C and can improve the collagen structure in the skin. To produce anti-aging cream, essential oils as active ingredients are added with various compositions and then formulated and on the skin of the dorsal hand. The results showed that the cream produced was homogeneous but still required the addition of an emulsifier. The cream also meets SNI in terms of pH. The creams in formulas 7 and 9 provide significant results in reducing the level of aging. In this study, it needs to take a longer time to determine the stability of the cream.

Abstract

The essential oil of lemongrass (Cymbopogon citratus) is a high-value commodity widely used in the food, pharmaceutical, and cosmetic industries due to its bioactive components such as citral. Optimizing its distillation process is necessary to achieve maximum yield with time and energy efficiency. This study aims to determine the hourly yield distribution of essential oil from Lombong-type lemongrass during steam distillation and to analyze its extraction kinetics to identify the optimal distillation duration. Distillation was conducted for four hours with yield recorded each hour, and the data were analyzed using pseudo-first-order and pseudo-second-order kinetic models. The results showed that the highest yield was obtained in the first hour (0.1882%), followed by a sharp decline, with no additional yield observed in the fourth hour. The pseudo-first-order model showed the best fit to the experimental data with a rate constant of k = 0,8012/hour. Meanwhile the pseudo-second-order model did not fit well. These findings indicate that the extraction process is dominated by external diffusion and the rapid release of surface volatile compounds. Therefore, it is recommended that distillation duration be limited to two hours to optimize energy and time efficiency.
