Formulation and Evaluation of Celery Leaf (Apium graveolens L.) Extract Hand Lotion with Variations of Triethanolamine and Stearic Acid Concentration as Emulgator

Abstract

Celery (Apium graveolens L.) contain flavonoid compounds, saponins, tannins and essential oils which function as antibacterials. The content of celery leaf extract is known to have very strong activity in inhibiting Staphylococcus aureus bacteria with an inhibitory zone diameter of 23.2 mm. Therefore, celery leaf extract has the potential to be developed into an active substance in making hand lotion. This research aims to determine the formulation and evaluation of celery leaf extract
hand lotion and determine variations in the concentration of triethanolamine and stearic acid on the physical properties of the lotion. Variations in the concentration of triethanolamine and stearic acid used in making celery leaf extract hand lotion are F1 (2% : 7%), F2 (3% : 6%), F3 (4% : 5%).
Physical quality testing includes organoleptic observations, homogeneity tests, pH measurements, spreadability, stickiness and viscosity. The data obtained were tested statistically using One Way ANOVA and Kruskall-Wallis tests. The research results showed that the hand lotion had a semi solid form, was light green in color, and had the smell of green tea essence. The lotions were homogeneous and has no coarse grains. The results of the lotion spreadability of the three formulas met the requirements, namely 5.28-6.35 cm. The adhesive power of lotions was found to be 6.23-10.29 seconds. The pH of lotions was 4.7-6.8. The viscosity of the lotions was 4184-7488 cps. Varying concentrations of triethanolamine and stearic acid have a significant effect on the physical properties of hand lotions including pH, spreadability, stickiness and viscosity.
