| Summary: | The synthesis of hybrid pigments has been studied as these provide a safer alternative to modern synthetic pigments that are stable but are unsafe. This paper provides a systematic review of previous research on hybrid pigments composed of anthocyanins combined with different mineral clays, particularly saponite, montmorillonite, halloysite, palygorskite, and sepiolite. The research was carried out by summarizing the related literature cited and comparing each paper to another by the processes that were used and interactions that occurred in creating the hybrid pigment. The findings showed that the literature cited used adsorption as the method of combining the anthocyanin dye and the mineral clays used; the interactions that occurred were the intercalation of the dye and stabilizer used. Additionally, it was shown that the hybrid pigments exhibited improvement with respect to their stability in different areas, particularly pH, chemical, thermal, color, and light stability. Overall, the paper has shown the development and improvement in hybrid pigment research, particularly with anthocyanin hybrid pigments. |
