Abstract

Hibiscus rosa sinensis L. is widely used by the community to decorate the garden because of its splendor. In addition, Hibiscus flowers containing anthocyanin and flavonoids have antioxidants, which function as antioxidants against free radicals. This natural dye can be obtained by extracting Hibiscus flowers through maceration using 96% ethanol. In this research, Hibiscus flowers were obtained from Sendang Rejo Village, Lamongan Regency. In the extract process, the Hibiscus flower’s petals were blended until smooth, then added to 96% ethanol (1 liter) and stirred for 30 minutes. Filtrate results were taken, placed in a porcelain dish, and put in an oven at 60 °C for a day. Four formulas were made with varying levels of Hibiscus flower extract: F1 (0%), F2 (2%), F3 (4%), and F4 (6%). Physical evaluation included organoleptic, homogeneity, dispersibility, pH, and qualitative tests for the identification of anthocyanins. The results of the organoleptic, homogeneity, dispersion, pH, and identification of anthocyanins evaluations were then analyzed descriptively. The data from the organoleptic test indicated that F1 had an odorless white color, while F2, F3, and F4 had a red and white color with a distinctive Hibiscus flower aroma. The homogeneity test revealed that while F1 had good homogeneity, F2, F3, and F4 were not homogeneous (heterogeneous). The spreadability test on the four formulas did not fall within the range of requirements, namely 5-7 cm, with an average value of 3.53, but this was related to several significant reasons. In addition, the pH test results matched the requirements for topical preparations, namely 4.5–6.5, with an average value of 5.075. In conclusion, Hibiscus flower extract obtained through the maceration method with 96% ethanol could not give a homogeneous red color from the anthocyanin substance. Physical evaluation and anthocyanin identification tests also obtained good results.

Abstract

Background: Octyl Methoxycinnamate (OMC) is one of the most commonly used sunscreen agents and can absorb UV-B. Due to its lipophilic nature and oil solubility, OMC can be formulated in the form of an emulgel, a semi solid system combining emulsion and gel, thus facilitating the delivery of hydrophilic and hydrophobic compounds. Objectives: This study aims to develop a sunscreen emulgel formulation containing OMC by evaluating its physical characteristics and hedonic test. Material and Methods: This research is an experimental study using OMC concentrations of 0% (F0), 5% (F1), and 10% (F2). The formulation was made in the form of emulgel by evaluating the physical properties including organoleptic test, homogeneity, pH, viscosity, and spreadability and hedonic test assessing texture, aroma, and color using a panel consisting of 30 people. The data obtained were analyzed using SPSS with the Shapiro-Wilk test, One-Way ANOVA, and Kruskal-Wallis. Results: The results of this study were obtained from three formulas with the following physical characteristics: Increasing the concentration of OMC did not affect color or consistency at each viscosity level. However, in terms of aroma, F1 and F2 contained the addition of OMC, which contributed to the aroma, while F0, without the active ingredient, had no aroma. Furthermore, increasing the concentration of OMC affected the pH, viscosity, and spreadability of the formulations. The results of the hedonic test showed that respondents preferred Formula 1 due to its texture. Conclusions: This study concluded that the addition of OMC at concentrations of 5% and 10% affected the pH, viscosity, spreadability, and texture of the preparation.
