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.
Types of Color Additives Used in Pharmaceuticals
The pharmaceutical industry uses dyes and pigments as color additives most commonly used in a variety of industrial applications, including food, drugs, and cosmetics. These include titanium dioxide, iron oxides, and non-synthetic pigments. Let’s explore them in more detail:
- Titanium dioxide
Titanium dioxide (TiO2) is an inert, unreactive substance used in a variety of pharmaceutical applications. Pharmaceutical manufacturers use Titanium dioxide as an excipient to color tablets, capsules, suspensions, and pastes. It can also be used as a food coloring to enhance the aesthetic appearance of food products more efficiently.
- Iron oxides
Iron oxide, also known as iron (III) oxide (Fe2O3), is a coloring agent used in the pharmaceutical industry to add color to tablets and capsules. It can be found naturally in hematite ore and rust. Iron oxide offers greater stability and resistance to environmental factors.
- Non-synthetic pigments
They are a type of pigment used in a variety of pharmaceutical dosage forms.
- Lakes
