Is Monoazo vegan?

Monoazo refers to a class of synthetic azo dyes and pigments characterised by a single azo group (-N=N-), used as colourants in cosmetics, food, and industrial applications. They are synthesised from petrochemical or coal tar precursors. Some may be processed through bone char filtration, introducing potential non-vegan concerns depending on manufacturing.
