The Evaluation of Physicochemical Properties of Corn Silk (Zea mays L.) Ethanolic Extract Face Scrub with Various of Corn’s Particle Size

Corn silk contains flavonoids as antioxidants so that it can be used as an active ingredient in topical preparations. Corn is used as a scrub to help remove dead skin cells, so the skin looks brighter. This study aims to determine the effect of scrub particle size by using sieve number variations on the physicochemical properties and stability of corn silk ethanolic extract face scrub. The corn scrub is sieved using sieve numbers 30, 40, and 60 mesh. The scrubs were dispersed into a cream formula of face scrub containing corn silk ethanolic extract of 1% (b/v). The formulas were tested for physicochemical properties, namely organoleptic, homogeneity, pH, sticking test, and dispersion test. Statistical analysis using Two Way ANOVA. The result showed that the difference in the number of particles causes differences in the physical properties of face scrub preparations in terms of viscosity and spreadability. The temperature variation in the stability test decreased the pH value but showed stable conditions in organoleptic, viscosity, and spreadability of the face scrub preparation. The particle size of the scrub of 40 mesh sieve produces the best physicochemical properties.
