Correction of chemical names - 18 February 2025

We have updated the names of the following chemicals in the Australian Inventory of Industrial Chemicals (Inventory) to the Chemical Abstracts Service (CAS) name. These corrections do not change the identity of the chemical substances themselves. 

For details of their Inventory listings, search our Inventory.

These amendments are in accordance with section 85 of the Industrial Chemicals Act 2019.
