What Are Color Additives?
Color additives, coloring agents, or colorants are excipients used to improve the visual appearance of pharmaceutical products. In other words, color additives refer to a dye, pigment, or any substance that imparts color to food, pharmaceuticals, cosmetics, or the human body. Color additives can be synthetic or natural in origin, depending on how they are produced.
Synthetic color additives are produced from coal-tar or petroleum-based reactions in a chemical laboratory. On the other hand, natural color additives or dyes are derived from naturally occurring sources, such as green vegetables, plants, trees, beetroots, minerals, animals, etc. There’s an ongoing debate between natural food colors vs synthetic food colors based on their chemical properties, uses, and purposes.
Synthetic dyes or color additives are more cost-effective and long-lasting than natural dyes, making them best suited for large production. Natural color additives are eco-friendly and offer potential health benefits. Furthermore, both forms of dyes are safe for human consumption when used properly or in limited quantities.
