Lemongrass & Butterfly Pea Flower Transparent Bathing Bar: A Refreshing Skincare Solution

This study presents the formulation and development of a transparent bathing bar incorporating natural extract of butterfly pea (clitiria ternatea) flower extract and lemongrass (cymbopogon citratus) essential oil. The primary aim is to create a natural, aesthetically appealing, and skin-friendly bathing product with added antioxidant, anti-inflammatory, and antimicrobial benefits. Butterfly pea flower is rich in anthocyanins, known for their antioxidant and skin-soothing properties, while lemongrass essential oil contributes antimicrobial action and a refreshing citrus aroma. The transparent base was prepared using natural glycerin, ensuring skin hydration and clarity of the final product. The formulation was evaluated for physicochemical properties such as pH, hardness, lathering, and transparency. The resulting bathing bar demonstrated good stability, appealing visual characteristics, and enhanced sensory and functional properties, making it a promising additional to the herbal cosmetic market.
