 European chemical Substances Information System

The European Chemical Substances Information System (ESIS) was a database established by the European Commission to provide information on chemical substances that are manufactured or imported in the European Union (EU). Its main objective was to support the implementation of various European regulations regarding chemical safety, such as the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) regulation. ESIS contained data on: 1. **Chemical substance identity**: Information on the chemical name, CAS number, and other identifiers.
