Formulation Of Herbal Sunscreen Using Natural Ultraviolet Filters

Abstract

The increasing awareness of the adverse effects associated with synthetic sunscreen agents has led to a growing demand for safer and eco-friendly alternatives. This study focuses on the formulation and evaluation of a herbal sunscreen using natural ultraviolet (UV) filters derived from plant-based sources. Herbal ingredients such as aloe vera, turmeric, green tea extract, coconut oil, carrot seed oil, and zinc oxide (of natural origin) were incorporated due to their inherent UV-absorbing, antioxidant, and skin-protective properties. The formulation was prepared in the form of a cream using suitable emulsifying agents and evaluated for physicochemical parameters including pH, viscosity, spreadability, stability, and sun protection factor (SPF). The results indicated that the formulated herbal sunscreen exhibited good stability, skin compatibility, and an acceptable SPF value, providing effective protection against both UVA and UVB radiation. The presence of bioactive phytochemicals such as flavonoids and phenolic compounds contributed significantly to UV absorption and free radical scavenging activity. Additionally, the formulation showed moisturizing and anti-inflammatory benefits, enhancing overall skin health without causing irritation or harmful side effects. Thus, the developed herbal sunscreen presents a promising alternative to conventional sunscreens, offering a safe, biodegradable, and cost-effective solution for photoprotection. Further studies involving in vivo evaluation and long-term stability are recommended to validate its commercial applicability.
