## Description

CosIng Checker is an online research and screening resource for cosmetic ingredient regulations. It helps users search 2,353 locally indexed EU records by INCI name, chemical name, CAS number, EC number or annex entry, and review relevant regulatory information. Record pages bring together details such as legal status, concentration limits, warnings, product scope, fragrance-allergen information and linked identifiers.

The site offers tools for checking individual ingredients or screening full INCI lists, comparing formulas and annex entries, calculating concentrations against displayed limits, and reviewing ingredient evidence across 13 markets. Its market comparisons identify the regulator, legal role, source language and, where reviewed, translation status. Data gaps are marked rather than presented as proof of approval.

CosIng Checker also provides EU annex hubs for prohibited and restricted substances, colorants, preservatives and UV filters, alongside an INCI glossary, CMR and allergen resources, coverage statistics, update history and source information. The service is designed to support regulatory research and faster compliance triage, while advising users to verify critical decisions against current official sources and legislation.
