«Comparing natural and synthetic colorants properties»
Natural and synthetic pigments have both advantages and disadvantages. It is usually easier and cheaper to isolate the pigment from plants than to synthesize. At the same time, synthetic dyes are more resistant to various environmental factors, which allows to use them widely.
