Uji Organoleptik dan Uji Total Plate Count (TPC) Pembuatan Lipstik Lanolin dari Wol Domba Dengan Penambahan Ekstrak Kulit Buah Naga Merah (Hylocereus polyrhizus)

Abstract

Lanolin (Adeps lanae), a natural wax derived from sheep wool, acts as an effective emollient that helps maintain skin moisture and improves the stability of cosmetic formulations. This study developed a lanolin-based lipstick enriched with red dragon fruit (Hylocereus polyrhizus) peel extract as a natural colorant and antioxidant source. The dragon fruit peel was extracted using 70% ethanol maceration, and lanolin was purified through heating and rotary evaporation. A Completely Randomized Design (CRD) was applied with four levels of extract concentration: P0 (0%), P1 (20%), P2 (40%), and P3 (60%). Sensory evaluations covered color, aroma, and texture, accompanied by irritation and Total Plate Count (TPC) tests. Results showed that the 60% extract formulation (P3) produced the most intense color, smoothest texture, and most acceptable aroma to panelists. P3 also exhibited the lowest microbial count, indicating potential antimicrobial activity from phenolic and flavonoid compounds in the extract. No irritation was observed in any formulation. These findings demonstrate that lanolin lipstick combined with red dragon fruit peel extract can serve as a safe, eco-friendly cosmetic alternative while adding economic value to agricultural and livestock by-products.
