Formulation and Evaluation of Multipurpose Herbal Liquid Shampoo

Herbal cosmetics have gained considerable importance in recent years due to increased awareness regarding the harmful effects associated with synthetic cosmetic products. Herbal shampoos are widely preferred because they are safer, biodegradable, eco-friendly, and possess fewer side effects compared to conventional shampoos. The present research work was aimed at the formulation and evaluation of a multipurpose herbal liquid shampoo using naturally available herbal ingredients possessing cleansing, nourishing, conditioning, anti-dandruff, and hair growth promoting properties. The herbal liquid shampoo was prepared using various plant-based extracts including Horse Gram extract, Amla extract, Fenugreek extract, Hibiscus extract, and Flaxseed extract. These ingredients were selected based on their traditional medicinal value and beneficial effects on hair and scalp health. Lemon juice was incorporated for maintaining the pH balance, while rose water containing fragrance was used for providing soothing effect and pleasant aroma. Coco glucoside served as a mild foaming and cleansing agent, whereas benzyl alcohol was incorporated as a preservative to improve formulation stability. The prepared formulation was adjusted with purified water to obtain the final volume of 100 ML. The formulated herbal liquid shampoo was evaluated for various physicochemical and performance parameters such as colour, odour, pH, texture, foam type, percentage solid content, appearance, cleansing action, skin irritation, and stability study. The shampoo exhibited brownish colour with pleasant odour and slightly thick texture. The pH of the formulation was found to be 5, which is considered suitable for scalp and hair compatibility. The formulation showed medium foam formation and effective cleansing action with soft hair feel after washing. Percentage solid content was observed to be 20.8%, indicating acceptable consistency and spreadability. The prepared shampoo appeared turbid due to the presence of multiple herbal extracts. Skin irritation studies revealed no signs of irritation, redness, or discomfort, confirming the safety of the formulation for topical application.
