Formulation and Evaluation of Herbal Sunscreen Lotion by Using Moringa Oleifera and Curcuma Longa Extract

The increasing awareness of the harmful effects of UV radiation has driven the demand for safer and more effective sun protection products. This study focuses on the formulation and evaluation of herbal sunscreen lotions using natural ingredients such as Moringa oleifera, Curcuma longa, Aloe vera, and other plant-based components. These formulations were developed using maceration and emulsification techniques, followed by a comprehensive evaluation of physical parameters, pH, viscosity, spreadability, homogeneity, stability, irritancy, and Sun Protection Factor (SPF). Among the three formulations (F1, F2, and F3), F3 demonstrated superior properties, including the highest SPF value of 39.65, indicating excellent photoprotective potential. All formulations were found to be non-irritant, thermally stable, and cosmetically acceptable. The results support the potential of herbal-based sunscreens, in combination with safe mineral agents like zinc oxide, as effective alternatives to chemical products, providing broad-spectrum UV protection with minimal side effects.
