TR25: EVALUATION OF BIOCOLORANT LIPSTICK FROM DRAGON FRUIT PEEL
AMIRUN HAKIM BIN AZALUDIN KOLEJ KEMAHIRAN TINGGI MARA LENGGONG
Dragon fruit peel, typically discarded as waste, poses an environmental issue
due to its large volume. This project aims to address this waste problem by
utilizing dragon fruit peel as a raw material to produce a natural biocolorant,
offering an eco-friendly alternative to synthetic colorants in cosmetic
products. The extraction process involves maceration using ethanol as the
solvent, followed by a screening process using a UV-vis spectrophotometer
to identify the active compound, betacyanin. Subsequently, the extract
undergoes spray drying to produce biocolorant powder. This biocolorant
powder is then used to formulate lipstick. The project evaluates the lipstick's
quality through skin irritation tests, hardness tests, determination of
betacyanin content, and pH value measurements.
