About Annex IV of Regulation (EC) No 1223/2009
Annex IV of Regulation (EC) No 1223/2009 contains the positive list of colorants authorised for use in cosmetic products within the European Union. Only colorants expressly included in this annex may be used for cosmetic colouring purposes; any colorant not listed is prohibited by default. Each entry specifies the scope of application: whether the colorant may be used in all cosmetics, only in rinse-off products, in products that do not contact mucous membranes, or with additional restrictions for the eye area. Some colorants also carry purity or maximum concentration restrictions. The Colour Index (CI) number provides unambiguous identification of the substance. BD-API synchronises changes to Annex IV and proactively notifies connected management systems, reducing non-compliance risk during reformulation. Colorants used exclusively for hair dyeing fall outside Annex IV and are regulated separately, primarily under Annex III. Explore the full Annex IV →
Positive lists are tightly governed
New SCCS opinions and amending regulations reshape this Annex regularly — an entry that changes must be reflected in your active formulations. BD-API delivers every change to your system via API, webhooks and automated alerts.
