What does a formula and INCI review check?

The review checks your ingredient list against EU Cosmetics Regulation Annex II (prohibited), Annex III (restricted), and CosIng database INCI names. US reviews check against FDA-prohibited and INCI naming conventions.

What happens if a prohibited substance is found?

The reviewer will flag it with the relevant regulation reference and recommend either reformulation or evidence that the substance is being used within a permitted function/concentration.

Is an INCI review part of the CPSR process?

Yes — ingredient safety is a core component of the CPSR (Part A). An independent INCI review can be done upfront to pre-screen your formula before commissioning a full CPSR.

What is INCI nomenclature and why does it matter?

INCI stands for International Nomenclature of Cosmetic Ingredients — the standardized international naming system developed by the Personal Care Products Council (PCPC) and adopted globally for cosmetic ingredient labelling. Under EU Cosmetics Regulation 1223/2009, all cosmetic products sold in the EU must display a complete ingredient list using INCI names in decreasing order of concentration (with exceptions for fragrance components listed as "parfum" or "aroma"). Incorrect INCI names — even for safe, permitted ingredients — constitute a labelling non-compliance that can lead to product withdrawal, CPNP rejection, or market surveillance action.

Prohibited and restricted ingredients: what a formula review checks

EU Cosmetics Regulation Annex II lists over 1,300 prohibited substances that may not be used in cosmetics. Annex III lists restricted substances — ingredients permitted only under specific conditions of use, concentration limits, and product types. A professional formula review cross-references your complete INCI list and concentrations against both annexes, plus relevant SCCS (Scientific Committee on Consumer Safety) opinions for ingredients under active evaluation. Common findings include: use of a prohibited preservative that was recently banned; a permitted ingredient used above its maximum permitted concentration; a restricted ingredient in a product type where it is not allowed (e.g., a preservative permitted in rinse-off products only, used in a leave-on product).

CosIng and the correct INCI nomenclature

The European Commission's CosIng database is the authoritative reference for INCI names for cosmetics sold in the EU. Each ingredient has a specific CosIng-listed INCI name, and using an outdated or informal ingredient name on your label is non-compliant. Common INCI nomenclature errors include: using a chemical IUPAC name instead of the CosIng-listed INCI name; using a trade name instead of INCI; using an abbreviated or simplified version of a multi-word INCI name; and misspelling INCI names (even minor spelling errors on the label are technically non-compliant). A formula review verifies every ingredient name against the current CosIng database.

US INCI requirements and cross-market compliance

In the United States, cosmetic ingredient labelling is governed by FDA's 21 CFR Part 701.3, which requires declaration in descending order of predominance by weight using the PCPC's INCI nomenclature as referenced in their International Cosmetic Ingredient Dictionary. While US and EU INCI names are largely aligned (both reference the PCPC system), there are differences in specific ingredient names and in how mixtures are handled. A cross-market formula review checks your ingredient list against both EU CosIng and FDA PCPC references, identifying any names that must differ between your EU and US label versions.
