Formulation And Evaluation Of Herbal Sunscreen Containing Butterfly Pea Flower

The increasing concern about the harmful effects of ultraviolet (UV) radiation on skin health has led to a growing demand for safe and natural alternatives to chemical sunscreens. This study investigates the formulation and evaluation of a herbal sunscreen incorporating natural ingredients, specifically butterfly pea flower extract, aloe vera gel, coconut oil, rose water, and vitamin E capsules. These ingredients were selected for their known beneficial properties: butterfly pea flower extract is rich in antioxidants, aloe vera gel is renowned for its soothing and moisturizing effects, coconut oil provides hydration and UV protection, rose water offers anti-inflammatory benefits, and vitamin E serves as a potent antioxidant.The formulation was prepared by blending the selected ingredients into an emulsion, ensuring uniformity and stability. The sunscreen was evaluated for key parameters, including its sun protection factor (SPF), stability, viscosity, and skin compatibility. SPF was determined using a UV spectrophotometric method, while stability was assessed through accelerated stability testing under varying temperature and light conditions. The texture of the sunscreen was characterized by assessing its spreadability and ease of application, with a particular focus on its non-greasy feel and moisturizing properties.The SPF evaluation indicated a moderate to high level of sun protection, with the formulation successfully blocking UV radiation. Stability tests showed that the sunscreen remained stable over a prolonged period, with no significant changes in its physical or chemical properties. Sensory evaluation revealed that the product was well-received in terms of texture and skin feel, leaving the skin hydrated and non-greasy after application. Additionally, the antioxidant and anti-inflammatory properties of the herbal ingredients were confirmed through in vitro tests, supporting the sunscreen’s dual action of protection and skin nourishment.
