The FDA (Food and Drug Administration) conducts pigment testing to ensure the safety of colors used in the food, drug, and cosmetic industries. This involves a series of tests designed to determine the chemical purity, color consistency, and safety for consumption or use. Key methods include spectrophotometry for measuring color intensity and purity, chromatography (HPLC or GC-MS) for identifying and quantifying chemical components, and in vitro and in vivo toxicological assays to assess potential health risks. The FDA sets strict guidelines and standards for pigments based on these tests, categorizing them into approved lists for specific uses. Manufacturers must comply with these standards to avoid enforcement actions. Regular updates to testing methodologies and safety requirements are done to adapt to new scientific findings and technological advancements.
