Glossary Synthetic Dyes

are man-made chemicals used to color materials

Synthetic dyes, also known as artificial or chemical dyes, are man-made substances used to impart color to materials such as textiles, hair, and food. These dyes are typically derived from petrochemical sources and are designed to provide consistent, long-lasting color. Unlike natural dyes, which are extracted from plants, animals, or minerals, synthetic dyes offer a broader range of vibrant colors and are often more cost-effective and easier to produce on a large scale.
