What cosmetic ingredient naming system is abbreviated INCI?

INCI stands for International Nomenclature of Cosmetic Ingredients.

It is the standardized naming system used to identify cosmetic ingredients on product labels. INCI names help manufacturers, regulators, professionals, and consumers recognize ingredients across brands and languages, even when a marketing name or everyday term differs. The system covers substances such as oils, waxes, pigments, preservatives, and other chemicals.

INCI names are not always the same as systematic chemical names. The convention mixes familiar English terms, scientific names, and Latin botanical names. For example, water may appear as “Aqua,” fragrance as “Parfum,” vitamin E as “Tocopherol,” and shea butter as “Butyrospermum parkii Butter.” This is why an ingredient list can look unfamiliar without representing a different substance.

The modern convention grew from rules established in 1973 by the organization now known as the Personal Care Products Council, formerly the Cosmetic, Toiletry, and Fragrance Association. A related misconception is that an INCI name proves an ingredient is safe or effective; it primarily provides standardized identification. Safety and performance depend on concentration, formulation, use, and applicable regulations.
