Abstract

Beetroot (Beta vulgaris L) apart from being good for consumption, is also good for use as a natural food coloring and cosmetic preparation. This research aims to make hair dye cosmetics from natural ingredients with a number of benefits that can increase beauty, but do not have side effects on the health of the user or the environment, by using beetroot plants as the main ingredient for the dye, and mordant which is an important component for strengthening the bond between dyes and fibers to prevent fading using lime (Citrus aurantifolia). Extraction of beet tubers was carried out using 70% ethanol solvent using the maceration method. Maceration is carried out for 3x24hours. This research used varying volumes of beetroot 2ml, 4ml, 6ml, 8ml and 10ml, with varying volumes of lime as mordant, namely 0.5ml, 1ml, 1.5ml, 2ml and 2.5ml. The research results showed that the best hair dye with a composition of 10ml of beet root extract with a volume of 2ml and 2.5ml of lime had a pH of 6.20 and 6.12 in accordance with the scalp pH standard, namely 4-6.5 in according to SNI 06-2692-1992, test value the color stability during washing changes on average in the 4th washing, the irritation test value is negative for redness, itching and swelling, indicating that the hair dye preparation does not irritate the skin, the organoleptic test value has an average value for color, aroma and texture of 1.82 and the value of absorbed wadar content of betacyanin pigment was R(Red)123=48.24%.

Abstract

This study aims to utilize sweet orange peel (Citrus sinensis) as an additive in the production of aromatherapy candles based on soy wax. Essential oil extraction was carried out using the maceration method with 96% ethanol as the solvent. The independent variables in this study included variations in the volume of orange peel extract (2–6 mL) and the mass of soy wax (100–300 g), while the dependent variables comprised pH measurement, melting point analysis, component analysis using gas chromatography–mass spectrometry (GC–MS), and organoleptic evaluation (aroma, shape, and color). The results showed that the orange peel extract yielded essential oil with a fresh citrus aroma and a pH ranging from 5.5 to 5.8. The melting point of the candles increased with increasing extract volume and soy wax mass, reaching a maximum temperature of 54°C. The best burning resistance was obtained at the combination of 250 g soy wax and 6 mL extract, with a burning duration of 4.49 hours. Hedonic testing indicated the highest aroma preference at the combinations of 100 g soy wax with 6 mL extract and 300 g soy wax with 5 mL extract, with a hedonic score of 4.93. GC–MS analysis revealed that the major components of the essential oil were D-limonene, linalool, and other alcohol compounds, which contribute to relaxation effects and a characteristic citrus aroma. Overall, the findings demonstrate that sweet orange peel extract has strong potential as a natural additive in the production of environmentally friendly and economically valuable aromatherapy candles.
