How the COLORANT function is used in CosIng

The COLORANT function is assigned by the European Commission in the CosIng ingredient inventory. This page currently lists 257 ingredients carrying that function label in the dataset, which helps you move from a functional claim to the exact ingredients that use it.

Exclusively or mainly intended to colour the cosmetic product, the body as a whole or certain parts thereof, by absorption or reflection of visible light. All authorised colorants are substances in the positive list of Annex IV to the Cosmetics Regulation 1223/2009.

Function assignments come from official EU CosIng data. They describe intended cosmetic use, but they do not replace regulatory review of each linked ingredient and any annex records tied to it.

Frequently asked questions

The COLORANT function, as defined in the EU CosIng database, describes the role this group of ingredients plays in a cosmetic formulation. There are currently 257 ingredients in the EU CosIng inventory assigned this function. Function labels are standardised terms used in Product Information Files (PIF) and ingredient declarations.

Yes. An ingredient's function in the CosIng inventory is independent of its regulatory status. An ingredient with the COLORANT function may also be listed in Annex II (prohibited), Annex III (restricted), or other annexes. Always check each ingredient's annex records for applicable conditions before formulating.

Ingredient functions are documented in the Product Information File (PIF) as part of the cosmetic product safety assessment. They describe the intended role of each ingredient in the formulation and support the safety assessor's review. Functions do not appear on consumer-facing product labels, which list only INCI names.
