research Antibacterial Effects of Herbal Extract Shampoo Combined with Synergistic Extracts
This study developed an herbal shampoo using extracts from Cassia alata, Curcuma longa, Lawsonia inermis, Rhinacanthus nasutus, and Sapindus emarginatus, evaluating their antibacterial effects. The combination of Lawsonia inermis and Curcuma longa showed the highest antibacterial activity against Pseudomonas aeruginosa and Staphylococcus aureus, while Rhinacanthus nasutus and Sapindus emarginatus were most effective against Staphylococcus epidermidis. The most effective formulation had a Minimum Inhibitory Concentration of 10⁻⁸ mg/ml. Stability tests indicated significant color changes at high temperatures. Consumer preference tests with 30 participants favored a formulation containing Sapindus emarginatus and Curcuma longa for color, foam, and overall acceptance.
