Development of Nanoemulsion from apis mellifera larvae oil for application in cosmetic
Abstract:
This research aimed to investigate the chemical composition and cosmeceutical potential of Apis mellifera larvae oil, alongside the development of nanoemulsion for cosmetic applications. Oil was extracted from 4. mellifera larvae using the cold-press method and analyzed for its chemical composition, Antioxidant, anti-elastase, anti-hyaluronidase, and irritation potentials were evaluated in vitro to assess bioactivities and safety. Nanoemulsions were developed using either A. mellifera larvae oil alone or in combination with natural oils (jojoba, sesame, and argan) Physicochemical characteristics, including particle size, polydispersity index (PDI), zeta potential, viscosity, pH, and stability under heating-cooling cycles, were evaluated. The findings revealed that the A. mellifera larvae oil was rich in satiarated fatty acids, with palmitic acid as the major component. The mil exhibited low radical scavenging activity (5.66 1.44%) and mild anti-wrinkle potential through elastase inhibition (24.10 0.00%) but showed promising hyaluronidase inhibition (55.5 = 6.8% * o) Irritation testing further confirmed its safety for topical application. Therefore, the oil was formulated into nanoemulsions for coumetic applications. Among the developed formulations, those incorporating sesame oil with 4. mellifera larvae oil demonstrated the most favorable characteristics, including a small particle size (148.37 0.64 nm), narrow PDI (0.25 0.01), stable zeta potential (32.53 1.05 mV), appropriate viscosity (33.33 ± 0.00 mPas), and skin-compatible pH (6.55 0.04). Furthermore, the formulations exhibited excellent stability after repeated heating-cooling cycles, underscoring their suitability for cosmetic use. Therefore, it can be concluded that 4. mellifera larvae oil demonstrated notable cosmeceutical potential with excellent safety, and its successful incorporation into nanoemulsions highlighted its promise as a novel ingredient for skin care
