Data sources and methodology
CosIng Checker currently indexes 2353 annex records derived from publicly available European Commission cosmetic ingredient materials and links them with the ingredient inventory where possible.
Source note for data sources
This page documents the public source files behind 2353 locally indexed annex records and shows when each annex was last imported.
Use this page to understand provenance and import timing, but consult the original source files and current law when a regulatory decision depends on exact wording.
Annex source files
Each annex below shows the local source file, the source update date carried by that file, the local import timestamp and the current number of indexed records.

Normalization notes
CosIng Checker improves readability and internal linking, but not every official field arrives in perfectly structured form.
- Multi-part product type notes are split into cleaner browsing groups.
- CAS and EC values can be linked across grouped pages and record detail pages.
- Ingredient inventory rows can be linked to annex records through restriction references, identifiers and INCI names.
- Search pages use normalized text so names, identifiers and related notes are easier to find.
- Some regulatory fields, such as warnings or concentration notes, remain textual because the official source is not always fully structured.
How to use this information
Use these source and methodology notes to understand where the data comes from, what has been normalized, and when to cross-check the official materials.
