What is INCI labeling and why does FDA require it?

INCI stands for International Nomenclature of Cosmetic Ingredients—a globally standardized naming system. FDA 21 CFR 701.3 requires US cosmetic labels to list all ingredients in descending order of predominance using INCI names, enabling consumers and regulators to identify every component. Errors in INCI ordering or nomenclature can trigger FDA warning letters. A cosmetic chemist generates the compliant INCI declaration directly from your batch formula.
