Synthetic-based colorants have been extensively used in several industries, viz., cosmeceutical, feed,pharmaceuticals, food and textile. However, the growing awareness of potential teratogenicity, carcinogenicityand environmental concerns of certain synthetic colorants have expressed several limitationsregarding their use in some products. These limitations, justifies the motivation to look for ecofriendlyalternatives (cf., natural colorants) to be used as coloring agents for industrial applications. The filamentous fungi Talaromyces amestolkiae appeared as a promising source of natural fluorescentred colorant (NFRC) for the development of custom-made latex gloves. In this study, some basic colorantproperties, including 3D-fluorescence and CIELAB color characteristics were first investigated systematicallybefore their incorporation in natural rubber latex (NRL) films. The NFRC-NRL films properties wereevaluated by physicochemical tests and toxicity through cell viability using 3T3 fibroblasts, wherein eluateof NFRC-NRL films (2.28 AU) revealed viability >70 % (exposing the biocompatibility). Regardless ofthe strategy proposed, it is shown as a proof-of-concept the potential application of NFRC in the NRLmatrix as a biocompatible alternative to produce sustainable commercial colored custom-made latexgloves.
