Formulasi dan Evaluasi Sabun Padat Transparan dari Ekstrak Bunga Rosella (Hibiscus sabdariffa L.)

Abstract

Rosella flower is a plant with an antioxidant effect because it contains anthocyanins included in the flavonoid group. Therefore, it is essential to develop rosella flower extract in the form of soap preparations. This present work formulated and evaluated transparent solid soap preparations with 70% ethanol extract. This laboratory experimental research analyzed transparent solid soap preparations that were made of three formulas with different concentrations of active substances, namely FI (0.5%), FII (1%), FIII (2%). In addition, the evaluation of solid soap preparations involved organoleptic observations (smell, color, shape), pH test, foam height test, and irritation test on volunteers' skin. The results of quality inspection of organoleptic preparations indicated that the higher the concentration of the active substance in solid soap preparations, the less transparent the soap looks; the pH test produced 10.63-11.43; the initial foam height test resulted in 80 mm, and the final rest got 70 mm, 60 mm, and 50 mm; skin irritation tested to volunteers showed a negative reaction. The formulation in this study was formula 1, which produced the best transparent soap. It is concluded that FI, FII, and FIII soap with 70% ethanol extract of rosella flowers can be formulated as transparent solid soap.

Physicochemical Quality of Transparent Solid Soap with The Addition of Forest Honey (Apis dorsata) as An Environmentally Friendly Sanitizer

“…The transparent solid soap formulation was made according, which was modified in the use of ingredient measurements, sorbitol as a substitute for liquid sugar or sucrose, and the addition of honey [11,12]. The formulation for adding forest honey with different concentrations (0%, 5%, 10%, 15%, and 20%) is presented in Table 1.…”

Quality Evaluation of Transparent Soap from Whey Waste with Butterfly Pea Flower Extract (Clitoria ternatea L.)

“…The formulation of a transparent soap preparation from tofu whey waste with flower extract is made in a dosage weight of 100 grams. The soap-making process uses the hot process method (Tungadi et al, 2022). Tofu whey waste acts as a substitute for sucrose in the composition of transparent solid soap preparations.…”

The combination tea of corn silk (Zea mays L.) and rosella flowers (Hibiscus sabdariffa L.): Antioxidant levels using different drying methods

“…This is because the rosella flower petals are bright red and have a sour taste. Chemical components that act as antioxidants in rosella flowers are anthocyanins which belong to the flavonoid compound group (Agustiarini & Wijaya, 2022;Aisiyah et al, 2017;Imran et al, 2022;Tungadi et al, 2022).…”
