Tool 
European chemical Substances Information System (ESIS) is a system that provides information on chemicals, related to:

- EINEC (European Inventory of Existing Commercial Substances)
    general information concerning a chemical substance like CAS number,
    EINECS number, Substance Name and Chemical Formula

- ELINCS (European List of Notified Chemical Substances)
    general information concerning a chemical substance like CAS number,
    ELINCS number or Substance Name

- HPVCs (High Production Volume Chemicals) and LPVCs (Low Production
    Volume Chemicals), including EU Producers/Importers lists
    information on the HPVCs and the LPVCs, where data have been
    reported by Industry

- Classification and Labelling (Risk and Safety Phrases, Danger etc...)

- ORATS (Online EUropean Risk Assessment Tracking System)
    information on the progress of implementation of Council Regulation
    (EEC) 793/93 also known as Existing Substances Regulation (ESR).

- IUCLID (International Uniform Chemical Information Data Base) Chemical
    Data Sheets
    extracts of data from the IUCLID on High Production Volume Chemicals
    reported by European Industry in the frame of the European existing
    chemicals risk assessment programme

- Priority Lists
    lists of priority substances which require immediate attention because
    of their potential effects to man or the environment
 

Purpose 
ESIS is a database containing general information and specific information reported by industry on chemicals, especially priority and High Production Volyme (HPV) chemicals.

Description 
The user can search for a chemical by its CAS or EINECS number.
