Data Sources and Methodology
CosIng Checker is built around publicly available European Commission cosmetic ingredient reference materials, including Annex II, Annex III, Annex IV, Annex V and Annex VI data. We transform raw official files into a cleaner, searchable and more readable experience so users can review ingredient records faster.
Our platform focuses on structured extraction, normalization and presentation of ingredient records, including chemical names, glossary names, CAS numbers, EC numbers, restrictions, warnings, product-type notes and update metadata. This makes official reference information easier to browse, compare and understand.
