Shampoo is the preparation of surfactants aimed at removal of surface grease, dirt and skin debris from hair, shaft and scalp without adversely affecting the user. The main aim of this study was to formulate herbal shampoos using Ethiopian plant extracts and to evaluate their physicochemical properties. The herbal shampoos were formulated using seed oil extracts of Lepidium sativum and Ricinus communis, and essential oil extracts of Lippia adeonsis Hochest ex. Walp koseret. The formulated herbal shampoos were evaluated for its organoleptic and physicochemical properties such as pH, surface tension, viscosity, dirt dispersion, antimicrobial activities and stability study. When investigation data were assessed, the formulations were pleasant, appealing, produced sufficient foam and showed good cleansing activities. The pH values were in a range of 5.90±0.22 to 7.45±0.19 and lower surface tension (23.39±0.20 to 31.89±1.04 dyne/cm) as well as acceptable viscosity with good shearing properties were obtained. The formulations products exhibited good antimicrobial activities against Escherichia coli, Staphylococcus aureus and Aspergillus Niger. This might be related to the presence of essential oil having linalool (73.13%) as dominating compound when analysed by gas chromatography-mass spectrometer (GC-MS), and synergetic effects of other ingredients in the formulations. When the surface morphologies of hair samples studied for cleaning efficacy of formulated herbal shampoo using scanning electron microscope (SEM), clean and smooth surface was observed for treated samples, which is comparable to that of marketed shampoo. The result indicated that the formulated herbal shampoo is good, having acceptable properties, at par with commercially available shampoos. However, additional investigation and further research and development are required to improve its quality and safety. |
