Dye regulations refer to the rules and guidelines set by governments and organizations to ensure the safety and quality of dyes used in various products, such as textiles, food, and cosmetics. These regulations help prevent harmful substances from being used in dyes, protecting consumers and the environment. In many countries, dyes must be tested for toxicity and approved before they can be sold. Organizations like the U.S. Food and Drug Administration (FDA) and the European Chemicals Agency (ECHA) oversee these regulations, ensuring that only safe and effective dyes are used in consumer products.
