Formulasi dan Uji In Vitro Nilai Sun Protecting Factor (SPF) Krim dari Cangkang Telur Ayam Ras

Chicken Eggshell Cream Sunblock Stabilitas Fisik The potential of chicken eggshell waste in Indonesia is quite large, which is produced + 133.703 every years. The main constituent of this shell is 98% of calcium carbonate (CaCO3) which functions to block ultraviolet light that will be exposed to the skin. This study aims to make a formula and determine the sun protecting factor (SPF) by in vitro test of cream from waste of this eggshells. The formula was made with difference concetration of this eggshell F1 (10%) and F2 (15%). Then the evaluation of physical characteristics includes organoleptic test, emulsion type, creaming, viscosity and pH as well as phase inversion before and after the accelerated condition for 10 cycles. Furthermore, the SPF was determined using a UV-VIS spectrophotometer at a wavelength of 290-320 nm and the measurement results were calculated using the SPF formula. The data from the evaluation of the physical stability of the cream were analyzed using SPSS with a partial T test with a confidence level of 95% and the significance was considered significant if P <0.05. Meanwhile, the SPF value was analyzed based on the sunscreen protection category. The results showed that F1 and F2 had adequate physical stability. The SPF value test results are CT 7500; CT 9000, F1 and F2 showed no difference in the UV protection category. All groups showed extra category protective UV activity
