Color Additives in Cosmetics: Regulatory Similarities and Differences Between the EU and US

Color additives are widely used in cosmetic and personal care products, contributing to product appearance, brand differentiation, and consumer appeal. However, certain colorants—particularly synthetic organic dyes and mineral pigments—may present safety concerns due to potential heavy metal impurities, sensitization risks, or systemic toxicity. Consequently, regulatory authorities worldwide have established stringent controls over their use in cosmetics. Among these, the European Union (EU) and the United States (US) operate two of the most influential regulatory frameworks for cosmetic color additives. Although both jurisdictions follow a "positive list" principle—allowing only specifically authorized color additives in cosmetics—their regulatory philosophies, approval mechanisms, and compliance requirements differ significantly.
