FORMULATION AND ANTIOXIDANT ACTIVITY TEST OF FACE TONER EXTRACT PREPARATION FROM 70% ETHANOL OF CUCUMBER FRUIT (Cucumis sativus L.)

Abstract

Cucumber (Cucumis sativus L.) is a natural ingredient with potential therapeutic properties for addressing various skin-related problems. The study aims to identify a suitable formulation for a facial toner extract that exhibits favourable physical properties as determined by organoleptic, homogeneity, pH, and hedonic testing. The present study employed an experimental approach to produce a 70% ethanol extract of cucumber fruit through the maceration method, utilising 70% ethanol solvent. Subsequently, the extract derived from the cucumber fruit developed four formulas to prepare face toners. The concentrations of these formulas were designated as F0 (0%), FI (0.5%), F2 (1%), F3 (1.5%), and F4 (utilising brand x toner as a positive control). The physical evaluation test yielded the fulfilment of the physical criteria for the toner, encompassing the organoleptic, homogeneous, pH, and hedonic tests. The IC₅₀ values obtained from the antioxidant activity test conducted on face toner preparations containing cucumber fruit extract at concentrations of 0.5%, 1%, and 1.5% were found to be 128 ppm, 91.017 ppm, and 62.218 ppm, respectively. The SPSS analysis reveals a significant difference in the IC₅₀ value among the various formulas. Specifically, F3 exhibits a smaller IC₅₀ value than the other formulas, indicating a stronger antioxidant activity. It is important to note that a smaller IC₅₀ value indicates a stronger antioxidant activity. The study's findings suggest a positive correlation existing between the extract's concentration and its antioxidant activity, specifically, the extract denoted as F and administered at a concentration of 1.5%.
