Search the industrial chemicals inventory

The Australian Inventory of Industrial Chemicals (Inventory) is a database of more than 40,000 chemicals available for industrial use in Australia. For information about the safety, hazard and risks associated with chemicals, use our assessment search.

Chemical search results

Search by CAS number
Search by keywords

Search with CAS numbers only. For multiple CAS number search, use comma (,) to separate CAS numbers. Example: 999-97-3, 4399-55-7

Use numbers and dash (-) only

You must search for each industrial chemical ingredient if you are importing or manufacturing (introducing) a product that has more than 1 chemical.

Search by CAS number

This is the best method. A CAS number contains digits that are divided by hyphens into 3 parts.

Make sure you don't include a blank space at the start or between your numbers and hyphens

The CAS Registry is maintained by CAS and they also assign CAS numbers to chemicals (for a fee). They have a limited free online resource called Common Chemistry for searching CAS numbers.

Other ways to try and find your CAS number include:

looking at Safety Data Sheets — you'll need to contact the manufacturer or supplier
through an internet search
search online catalogues of chemical suppliers

I've found my chemical — find out what your search results mean

I can't find my chemical — learn the reasons why and what to do next

Searching by keyword

CAS proper name

If you do not have the CAS number your next best option is to search using the CAS name for the chemical.

Common names

Some common names for chemicals are on the Inventory but are restricted to the most commonly used chemicals. Your results will most likely be a very broad list of candidate chemicals.

Molecular formula

You can search by molecular formula e.g. C12H12N2O3, but you may get a very large number of results. Be as specific as possible in your search to get the most meaningful results.
