Formulation and Evaluation of Naturally Derived Shampoo Bar

A shampoo bar is a solid form of a conventional hair cleaner. Shampoo bars are a popular alternative to traditional liquid shampoo providing a convenient, eco-friendly, and travel-friendly option for consumers. Shampoo bars do not only eliminate plastic containers. Even though natural shampoo bars are safer and perform better than synthetic ones. Naturally derived shampoo bars are composed of natural ingredients that are free from harsh sulfates like those in synthetic shampoos. In order to minimize the use of plastic the present study aimed to formulate shampoo bars made from natural ingredients and evaluate their physicochemical properties. Ingredients from different kinds of natural sources were incorporated to formulate the naturally derived shampoo bar. To evaluate the physicochemical characteristics of the formulated naturally derived shampoo bar various types of tests were performed including visual inspection, pH, foam ability, and stability. The dirt dispersion test and surface tension measurement were evaluated. Results indicate that the shampoo bar made from natural ingredients performs satisfactory cleanliness. Even though the physicochemical evaluation gives the best results and all of the ingredients used in this formulation are safer, further research is necessary to increase its quality and safety with better cleansing and conditioning properties.
