Abstract

4-OH-chalcone is suspected of absorbing and reducing ultraviolet radiation intensity exposed to the skin. It was formulated in gel dosage form using a combination of 0.50-1.00 w/w carbopol content, 19-20 w/w propylene glycol content, and 0.50-1.00 w/w CMC-Na content. This study aimed to optimize the three gel bases and evaluate the physical properties, physical stability, and activity of 4-OH-chalcone gel as a sunscreen using in vitro method. Simplex Lattice Design (SLD) method was used to optimize the gel base using Design Expert software version 10.0. The activity of 4-OH-chalcone gel as sunscreen was determined spectrophotometrically by determining the Sun Protecting Factor (SPF) value, percent transmission of erythema ( TE), and percent transmission of pigmentation ( TP). Data were analyzed statistically using SPSS Statistical software. The optimum formula of 4-OH-chalcone gel was 0.50 w/w carbopol content, 0.50 w/w carboxymethylcellulose sodium content, and 20.0 w/w propylene glycol content which had a pH of 5.59, viscosity of 37.4 dPa.s, spreadability of 28.8 cm2, adhesive time of 1.28 seconds, SPF value of 28.65, , TE value of 16.44, TP value of 0.24, and relatively stable physical properties.
