EU CosIng and INCI: what formulators actually use
Educational content only—not legal, regulatory, or medical advice.
INCI (International Nomenclature of Cosmetic Ingredients) is the standard ingredient naming system shown on cosmetic labels in many markets. In the EU context, the CosIng database ties those names (and related identifiers) to cosmetic function, allowed uses, and restrictions where applicable.
Why CosIng is not a single “yes/no” button
A CosIng entry may show whether a substance is allowed, restricted, or banned under the cosmetic Regulation—often with conditions. You still must read which annex or implementing rule applies, the product category, max concentrations, warnings, and any overlapping national measures. The database is a navigation aid to official requirements, not a substitute for reading the underlying legal text.
Matching your raw material to the right row
Suppliers may sell salts, hydrates, or solutions under trade names. If your CAS or structure maps to a different INCI line than the one on your label, you risk non-compliance even when “the chemical” is familiar. Normalize to the INCI that will appear on-pack and trace it to the regulatory row you relied on.
CosIng vs REACH-only obligations
Cosmetic placement and chemical law intersect. Something can appear workable in CosIng for rinse-off use but still carry documentation or labelling duties from broader frameworks. Your cross-functional review usually includes both regulatory affairs and product safety—not only R&D.
