FORMULATION AND EVALUATION OF OPTIMIZED SHAMPOO CONTAINING SYNTHESIZED CHOLINE LAURYL SULFATE SURFACTANT

Abstract

This study presents the formulation and evaluation of a shampoo containing Choline Lauryl Sulfate surfactants. Seven batches (A to G) were prepared, incorporating key ingredients such as Choline Lauryl Sulfate and Sodium Cocoyl Isethionate. The formulations were assessed for physical appearance, pH, viscosity, foamability, cleaning efficiency, tensile strength, spreadability, zeta potential, detergency, stability, and irritancy. The physical appearance ranged from clear and yellowish to opaque white, with pH values between 5.3 and 5.8, indicating mild acidity suitable for scalp use. Viscosity measurements showed consistency across batches, with values between 2400 to 2600 cP. Foamability was highest in batch C (470 mL), correlating with its high cleaning efficiency and tensile strength (13.0 N). All batches demonstrated good spreadability, with batch C again leading at 7.8 cm. Stability tests confirmed all formulations were stable at room temperature, and none showed irritancy, ensuring safety for consumer use. The findings suggest that the newly formulated shampoo, particularly batch C, holds promise for effective and safe hair care, offering potential advantages over existing commercial products. Further research could focus on long-term effects and expanding ingredient diversity to enhance product efficacy and consumer appeal.
