Annatto Seed (Bixa Orellana) as an Alternative Highlighter

ABSTRACT 

This research proposes to investigate the feasibility of Annatto seeds (Bixa Orellana) as a sustainable and non-toxic alternative to conventional chemical-based highlighters. Current commercial highlighters often contain synthetic dyes and solvents, raising environmental and health concerns. This study will explore the coloring pigments of Annatto seeds, including solvent extraction with Ethyl Alcohol, to determine optimal pigment yield and color intensity. The resulting extracts will be tested for their efficacy as highlighting agents on paper. Assessment will include evaluation of color vibrancy, permanence, and ease of application. Furthermore, the environmental impact of the annatto-based highlighter will be assessed by comparing its lifecycle to that of conventional highlighters, considering factors such as biodegradability and resource consumption. The anticipated outcome is a viable, eco-friendly alternative to existing highlighters, contributing to a more sustainable stationery option and potentially reducing the environmental burden associated with highlighter production and disposal. The results will inform the development of a practical and commercially viable Annatto-based highlighting product.
