Abstract

Facial skin problems can occur in everyone, such as acne, dark spots, dull skin, wrinkles, etc. The butterfly pea flower (Clitoria ternatea L.) is a plant with various activities such as antibacterial and antioxidant. It can help prevent various facial skin problems. The study aimed to determine the concentration and effect of carbopol 940 on the characteristics of facial wash preparations. This research was experimental by extracting butterfly pea flowers using the maceration method and 70% ethanol solvent. Then a facial wash preparation was made with variations in the concentration of carbopol 940 as a gelling agent, namely 1%, 1.5%, and 2%. Data analysis was carried out by comparing characteristic evaluation results with SNI, and stability results were analyzed using Paired T-test. The results showed the characteristics of butterfly pea flower facial wash with variations in carbopol concentration 940 had a dark blue to dark purple color, had a slightly liquid viscous texture to very thick, smells typical of butterfly pea flowers, and was homogeneous. As well as the results of the evaluation of the pH of the preparation were suitable, the viscosity of the preparation was suitable, the foaming power of the preparation is suitable, and the dispersal power of the preparation was suitable. The addition of carbopol concentration 940 affects the pH, viscosity, and dispersion. So, if the higher concentration of carbopol, it would cause the viscosity of the preparation to be higher, and would be inversely proportional to the pH and dispersion power of preparation that was getting lower. In addition, it also affects the intensity of the color of the preparation. The best facial wash formula based on characteristic evaluation was F1 preparation with a carbopol concentration of 940 of 1% because it mets the SNI requirements.
