Formulation and Evaluation of Polyherbal Based Shampoo

This study aimed to develop and evaluate a polyherbal shampoo using natural, plant-based ingredients that deliver effective cleansing, conditioning, and scalp compatibility without synthetic additives. In response to growing consumer demand for eco-friendly personal care products, Ayurvedic botanicals such as amla, ginger, hibiscus, aloe vera, bhringraj, senna, and shikakai were selected for their well-documented antimicrobial and nourishing properties. Herbal extracts were prepared via maceration and decoction, followed by phytochemical screening to identify bioactive constituents. Seven formulations (F1–F7) were developed using a gelatin base, incorporating herbal extracts, natural fragrance, gelling agents, and pH regulators. Each shampoo was evaluated for physicochemical and aesthetic parameters, including appearance, pH, viscosity (measured at 26 ± 1°C and 120 rpm using a Labman LMDV60 viscometer), foam generation and stability, total solids, dirt dispersion, and washability. Among all prototypes, Formulation F5 demonstrated superior performance: pH of 5.16, viscosity of 946.0 mPa·s, foam stability of 90 mL after 1 minute, and solid content of 23.88%. It effectively dispersed ink and rinsed cleanly, while also exhibiting favorable sensory attributes such as pleasant aroma, golden honey color, and commercial-grade texture. These results confirm that combining multiple herbal extracts in a single formulation can yield a safe, effective, and sensorially appealing shampoo. Formulation F5 stands out as a promising eco-conscious alternative to conventional shampoos, supporting further innovation in herbal-based personal care products.
