“…Accordingly, all the formulations possessed a good fragrance due to the presence of eucalyptus essential oil as a scent. The LAK essential oil itself imparts a pleasant aroma to the shampoos and has been traditionally used as a food flavoring agent and preservative [62]. Among the four formulations, herbal shampoo F-4 possessed the strongest LAK essential oil aroma and contained the highest concentration (i.e., 12%) compared to the first three formulations.…”

Shampoo prepares surfactants to remove dirt, surface grease, and skin debris from hair, shaft, and scalp without harming the user. This study aimed to formulate herbal shampoo using Ethiopian plant extracts and evaluate their quality parameters. Herbal shampoos were formulated using seed oil extracts of Lepidium sativum L. and Ricinus communis L., and essential oil extracts of Lippia adeonsis Hochst ex. Walp koseret, along with other ingredients. The formulated herbal shampoos were evaluated for their organoleptic and physicochemical properties such as pH, surface tension, viscosity, dirt dispersion, antimicrobial activities, and stability. When the investigation data were assessed, the formulations were pleasant and attractive, produced sufficient foam, and showed suitable cleansing activities. The pH values were in a range 5.90 ± 0.22–7.45 ± 0.19, and lower surface tension (23.39 ± 0.20–31.89 ± 1.04 dyne/cm) together with acceptable viscosity with good shearing properties were obtained. The formulated products exhibited good antimicrobial activities against Escherichia coli, Staphylococcus aureus, and Aspergillus niger. When the surface morphologies of hair samples were examined using a scanning electron microscope (SEM), a clean and smooth surface was observed for treated samples, comparable to that of the marketed shampoo. This result indicated that the formulated herbal shampoo is good, having acceptable properties at par with commercially available shampoos. However, further investigation, research, and development are required to improve its quality and safety.

Background: Lippia adoensis var. koseret is a well known medicinal plant endemic to Ethiopia. It has been traditionally used to treat different infectious diseases and also in food preparation as condiment. The aim of the current study was to evaluate antibacterial and antifungal activities of water, ethanol and methanol based crude extracts of L. adoensis var. koseret against selected human pathogenic bacteria and fungi. Methods: Crude extracts of L. adoensis var. koseret were extracted by maceration method. Disc diffusion assay of the extracts were carried out in four different concentrations against three different bacteria species (Staphylococcus aureus, Enterococcus faecalis and Escherichia coli) and two clinical isolated fungal species (Candida albicans and Aspergillus flavus) by using Kirby-Baur disk diffusion method. Agar dilution method was used to determine the minimum inhibitory concentration, the minimum bactericidal and fungicidal concentrations of the extracts against similar microorganisms. Results: Water-based extract of L. adoensis var. koseret exhibited significantly less antimicrobial activity as compared to ethanol and methanol crude extract against tested isolates of bacteria and fungi (P < 0.05); while, there was no significant difference between ethanol and methanol extracts. Among the tested microorganism S. aureus, was the most sensitive of all whereas C. albicans was the most resistant microorganism to alcohol based extract of L. adoensis var. koseret. The minimum inhibitory concentration of L. adoensis var. koseret ranged from 3.12 to 25mg/ml in the alcohol based extracts but it was higher in the water-based extract. The lower bactericidal concentration (5.20 mg/l) and the highest fungicidal concentration (37.50 mg/ml) were observed in methanol based extracts against S. aureus and C. albicans, respectively. Conclusions: Antimicrobial activity of L. adoensis var. koseret varies with extraction solvent and tested microorganisms.
