Endophytic fungus RS3 isolated from coastal plant sarang semut (Hydnophytum formicarum) produced extracellular black pigment. The aims of this research were to obtain the pigment, to characterize and to determine the photoprotector activity. This research was conducted into several steps, that were determination of the best precipitating agent, characterization using instrument and solubility analysis, and analysis of Sun Protection Factor (SPF). Results showed the pigment was precipitated using acid solvent with pH ≤ 2.5. Functional groups of pigment were hydroxyl, aromatic ring, phenol and amine. According to its characteristics, black pigment produced by RS3 isolate was proposed as melanin. The photoprotector analysis showed the SPF value was 11.33.

In the present study, oil-in-water (O/W) sunscreen emulsions were prepared containing different portions of lignin (LGN), multiwall carbon nanotubes (MWCNTs) and graphene oxide (GO) nanoadditives. The stability in terms of pH and viscosity of emulsions was thoroughly studied for up to 90 days, exhibiting high stability for all produced O/W emulsions. The antioxidant activity of emulsions was also analyzed, presenting excellent antioxidant properties for the emulsion that contains LGN due to its phenolic compounds. Moreover, the emulsions were evaluated for their ultraviolet (UV) radiation protection ability in terms of sun protection factor (SPF) and UV stability. SPF values varied between 6.48 and 21.24 while the emulsion containing 2% w/v MWCNTs showed the highest SPF index and all samples demonstrated great UV stability. This work hopefully aims to contributing to the research of more organic additives for cosmetic application with various purposes.
