<![CDATA[There is evidence that an ethanol extract from the leaves of the kalakai tree (Stenochlaena palustris (Burm F.) Bedd.) may provide ultra-protective sun protection. The purpose of this study is to analyze the stability of a sunscreen spray gel composition that contains an ethanol extract of kalakai leaves. We used a rotary evaporator to concentrate the kalakai leaf ethanol extract until it was thick, after macerating the leaves in 70% ethanol solvent. A spray gel formulation containing EEKL was subsequently created, with EEKL concentrations of 5% (FI), 7.5% (FII), and 10% (FIII). The physical stability of the EEKL Spray gel formula was examined by six cycles of the cycling test technique in a climatic chamber with temperatures of 40°C ± 2°C and 4°C ± 2°C. Organoleptics, consistency, thickness, pH, adhesive spreading ability, and spray pattern are some of the tests that are conducted. Using a UV-Vis spectrophotometer set at 290-320 nm wavelength, the sunscreen test was conducted. A t-dependent test was used to examine the quantitative data on physical stability and sunscreen. No significant variations were seen throughout six storage cycles (p>0.05), indicating high physical stability, for the three EEKL Spray gel compositions (FI:5%, FII:7.5%, FIII: 10%). Formula III, which falls under the ultra protection category and had the highest average SPF value before and after the cycling test at 35.82 ± 0.50, exhibited no significant change (P>0.05) in the sunscreen activity during the six storage cycles, according to the results of the stability test of the EEKL Spray gel sunscreen activity in the three formulas.]]>
