Exposure to ultraviolet (UV) radiation from sunlight is a major cause of skin damage. Sunscreens are widely used to protect the skin, and there is growing interest in multifunctional skincare products offering both sun protection and hydration. This project focuses on the formulation and evaluation of a moisturizing sunscreen spray containing walnut oil, a natural ingredient rich in essential fatty acids, antioxidants, and vitamin E, known for moisturizing and mild photoprotective effects. The study aims to develop a stable, effective, and user-friendly product, evaluating its physicochemical properties, spreadability, sun protection factor (SPF), and overall performance. The formulated herbal sunscreen spray demonstrated excellent physical characteristics, a skin-compatible pH, and ideal spreadability. It successfully passed the 24-hour irritancy test, proving its safety for human application. The synergistic inclusion of Walnut oil and Aloe Vera resulted in a significant delay in sunburn onset, confirming its efficacy as a natural UV protectant. This product stands as a viable, natural, and safe alternative to synthetic sunscreen lotions, offering the dual benefits of effective sun protection and deep moisturization.
