Abstract

Green tea leaf extract is a promising active component for sunscreen products due to its high flavonoid content, particularly catechins. Cream was selected as the formulation type owing to its ease of application and user comfort. This research aimed to investigate the influence of different concentrations of stearic acid (12%, 11.5%, 11%, 10.5%, and 10%) and TEA (2%, 2.5%, 3%, 3.5%, and 4%) on the physical stability of the cream and to evaluate the corresponding SPF values. An experimental design was used, involving five formulations containing green tea leaf ethanol extract, with assessments of physical stability and SPF conducted at 0, 1, 2, and 3 months. Results indicated that formulation F4 demonstrated optimal physical stability over the three-month period, with viscosity of 22,777 Cps, spreadability of 6.7 cm, and adhesion time of 6.67 seconds. Meanwhile, formulation F2 achieved the highest SPF, measured at 39.82. Based on the results of the ANOVA analysis, it can be concluded that variations in the concentration of stearic acid and TEA do not have a significant effect on the physical stability of the cream and the cream is declared stable during storage, as indicated by a significance value of more than 0.05.
