Internet Sites

Chemical Information Databases

Given below are some links which may be useful to find chemical information. It should be noted that information on these links may not be accurate.

• EU Existing chemicals page http://ecb.jrc.it/existing-chemicals/
  The EU Existing chemical inventory, EINECS, can be searched on this site by using chemical name or EINECS numbers. This site is particularly useful to identify CAS number when an EINECS number is available.
   

• EU cosmetics chemicals list http://ec.europa.eu/enterprise/cosmetics/cosing/

  
  Information on cosmetic ingredients and their chemical identities are available on this site.
   

• National Library of Medicine (US)
  http://chem.sis.nlm.nih.gov/chemidplus/chemidheavy.jsp.  This site lists chemicals and available toxicity information. It is particularly useful as it lists chemicals which are not on major inventories.

• MSDS-Search http://www.msdssearch.com
  The link on this site can be used to find other sites where the chemical identities can be searched.

Internet search engines

Any Internet search engine (Yahoo, Ninemsn, Google etc) can also be used to find if information on chemical name and CAS number.

Search results can be narrowed down using the advanced search options (contains phrase, exactly etc). An easier way is to add additional search terms. For instance if you are searching for a chemical name only and get more than 2000 hits, just add the term 'CAS number' and redo the search. This will show the site hits where both the 'chemical name' and CAS number' are on the web site.
