Beauty Business

International Nomenclature of Cosmetic Ingredients — a standardized system of naming cosmetic ingredients using Latin and English scientific nomenclature, required on product labels in most major markets, enabling consumers and professionals to identify ingredients consistently across brands and regions.

Deep Dive

Standard Purpose

INCI was developed to create a universal language for cosmetic ingredients, eliminating confusion caused by varying trade names, marketing terms, and regional naming conventions. Under this system, shea butter is always listed as ‘Butyrospermum Parkii (Shea) Butter,’ regardless of brand or country.

Labeling Requirements

INCI listing follows a descending concentration order for ingredients above 1%, with those below 1% listed in any order. This concentration-based listing helps consumers assess product composition, though it cannot reveal exact percentages of active ingredients.

Consumer Literacy

The rise of ingredient-conscious beauty consumers has elevated INCI from a regulatory formality to a marketing focal point. ‘Skintellectuals’ who decode INCI lists influence purchasing decisions across social media, driving brands toward greater ingredient transparency.

OSF Perspective

OSF champions INCI literacy as an essential skill for beauty consumers and professionals alike — understanding what's actually in a product empowers better purchasing decisions.
