INCI names are the standardized ingredient names that appear on cosmetic labels worldwide, so the same raw material reads identically on a jar sold in Paris, London, or New York. The acronym stands for International Nomenclature of Cosmetic Ingredients, a naming system maintained by the Personal Care Products Council through the International Cosmetic Ingredient Dictionary — which is why your label says Butyrospermum Parkii Butter where your marketing says shea.
The list follows rules, not preference. Ingredients at 1% or more are listed in descending order by weight; below 1%, they may appear in any order — which is why a hero active can legally sit low on the list. Colorants may be grouped at the end under their CI numbers, fragrance compounds hide behind the single word "parfum," and the designated fragrance allergens must still be named individually above set thresholds — a list the EU expanded substantially in 2023. In the EU, the ingredient list is a labeling requirement under Regulation (EC) No 1223/2009; the US applies its own labeling rules with the same naming backbone.
Why It Matters to Your Brand
The INCI list is the most-read technical text your brand publishes — by regulators screening compliance, by retailers running restricted-substance policies, and by ingredient-literate customers with an analysis app open. Errors here are cheap to make and expensive to keep: wrong order, trade names where INCI names belong, or a missing allergen can hold a shipment at a distributor's desk or get artwork rejected after printing. The list is also public by design, which surprises founders protective of their formula — more on that below.
How the Factory Side Handles It
The factory generates the INCI list from the master formula, because only the factory knows the full composition of every raw material it buys — a single trade-name emollient can contribute three INCI entries. The brand's job is fidelity: the artwork must reproduce that list letter for letter, in the right order, for each market's language rules. The list's earliest ancestor is the ingredient direction inside your cosmetic product brief; by launch, that direction has become a legally fixed text that changes only when the formula does.
Frequently Asked Question
Does publishing the INCI list give away our formula?
No. The list discloses what is in the product and the broad order of concentration above 1%, but not the percentages, the raw material grades, the suppliers, or the process — and those are where a formula's real identity lives. Two products can share an identical INCI list and behave nothing alike. The names are public by law; the recipe stays protected as a trade secret, which is exactly how the industry keeps both regulators and competitors satisfied.
