Abstract

Skin is the body's outermost protective organ and is susceptible to damage caused by free radicals, ultraviolet (UV) radiation, and environmental pollutants, which can reduce skin moisture and accelerate premature aging. One approach to maintaining skin health is the use of body lotion containing natural antioxidants. Dayak onion bulbs (Eleutherine palmifolia (L.) Merr.) contain flavonoids, anthocyanins, and phenolic compounds that exhibit antioxidant activity, making them potential natural active ingredients for topical formulations. Objective: This study aimed to formulate an ethanolic extract of Dayak onion bulbs into a body lotion and to evaluate its physical characteristics, safety, and effectiveness as a skin moisturizer. Methods: The extract was obtained by maceration using 96% ethanol and formulated into body lotion at concentrations of 5%, 10%, and 15%. The formulations were evaluated for organoleptic properties, homogeneity, pH, spreadability, adhesiveness, stability, acceptability, skin irritation, and moisturizing effectiveness in volunteers over a four-week period. Results: All formulations met the required physical quality standards, were homogeneous, exhibited a pH of approximately 6, remained stable during storage, and caused no skin irritation. All formulations improved skin hydration, with the 15% extract formulation showing the greatest moisturizing effect compared with the 5%, 10%, and control formulations. Conclusion: The ethanolic extract of Dayak onion bulbs has the potential to be developed as a natural active ingredient in body lotion formulations that are safe, physically stable, and effective in improving skin moisture.
