About Annex V of Regulation (EC) No 1223/2009
Annex V of Regulation (EC) No 1223/2009 lists the preservatives authorised for use in cosmetic products in the European Union. Only preservatives included in this annex may be used to inhibit the development of micro-organisms in cosmetics. Each entry defines the maximum permitted concentration, the product categories in which it may be used, the applicable specific conditions, and any mandatory labelling warnings. Modifications to this annex are published periodically in the Official Journal of the EU following an opinion from the SCCS (Scientific Committee on Consumer Safety) and are automatically reflected in this database. BD-API synchronises these updates on a continuous scheduled basis and allows manufacturers and Responsible Persons to verify in real time whether their formulations comply with the current conditions of Annex V, integrating CosIng information into their audit and quality control workflows.

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.
