Secondary notification of Irgalube 232

The National Industrial Chemicals Notification and Assessment Scheme (NICNAS) has published a secondary notification of the existing chemical, Irgalube 232. The secondary notification applies to all persons who import the chemical and products containing the chemical for use in the flotation process in mining operations. The chemical may also be known by the following trade names:

  • CGA 28-0132
  • TKA 40116

The original assessment (NA/638), completed in December 1998, assessed the use of this chemical as an anti-wear additive in hydraulic fluids and compressor lubricating oils. Based on the data available at that time, the chemical was not classified as hazardous to human health or the environment.

Reasons for secondary notification

Secondary notification is required as the chemical will now be used as a collector in the sulphide flotation process in mining operations and, in addition, the intended introduction volumes significantly exceed those previously assessed. Furthermore, new studies are available that were not assessed at the time of the assessment as a new chemical. The new use may potentially result in release of the chemical to the environment with increased risk of adverse effects to the aquatic environment. Therefore, a reassessment of the human health and environmental risks for the chemical is required.

Secondary notification requirements

The specified persons to whom this notice applies must:


The penalty for non-compliance may include prohibition from further importation or manufacture of the chemical.

Due Date

Secondary notification of the chemical must be received by the Scheme no later than 1 May 2018.

Information required for secondary notification

Chemical Identity, Properties and Uses

  • Trade name(s) under which the chemical is marketed by the introducers.
  • Annual import volumes of the chemical.
  • Concentration of the chemical as imported and in end-use products.
  • Description of transportation, packaging and storage of the imported chemical and of the end-use product.
  • If importers of the chemical are formulating end-use products, the description of the formulation/packing process and disposal of wastes resulting from the process.
  • Detailed description of the sulphide flotation process involving the chemical including the concentration and volume of the chemical used during the process.
  • Description of the capture, storage, treatment and disposal of gangue minerals and waste fluids containing the chemical produced from the sulphide flotation process, including:
  • Expected volumes of gangue materials and waste fluids containing the chemical produced during each process.
  • Concentration of the chemical in these gangue materials and waste fluids during each process.
  • Description of the subsequent processing of the final mineral concentrate to generate pure metal products, including:
  • If multiple methods are used in Australia (e.g. pyrometallurgy and hydrometallurgy), the expected volume of the chemical processed by each method and how generated wastes containing the notified chemical are stored, treated and disposed of if they do not undergo total destruction.
  • Description of the handling of the chemical during reformulation (if any) and use, including:
  • Description of work done by each category of workers (transportation, storage, reformulation (if any), mining operations).
  • For each category of worker handling the product containing the chemical, the number of workers involved in each category, frequency and duration of each activity (e.g. hours per day and days per year).
  • Measures to prevent worker exposure.

Human health and environmental data

  • toxicology data for the chemical, or a suitable analogue
  • ecotoxicology data for the chemical, or a suitable analogue
  • environmental fate studies for the chemical, or a suitable analogue
  • Data already provided to the Scheme need not be resubmitted.

Safety Data Sheet (SDS)

  • Copies of SDSs for the chemical and products containing the chemical.

Exempt information applications

To apply for certain information to be treated as exempt from publication, use Application for Exempt Information (Form 3). Note that certain items of ‘basic information’, as defined in section 75(2) of the ICNA Act cannot be exempted from publication. An application for exempt information should be accompanied by an application fee of $1,150.

Additional persons with relevant information

In addition to the requirement to give secondary notification, any persons with information relevant to the assessment of the chemical and not covered in the original assessment are encouraged to submit the information for consideration.

Information collected

Information collected by the Scheme may be provided to State, Territory or Commonwealth regulatory agencies for the purposes of monitoring compliance under relevant legislation. Information that is designated as ‘exempt’ will not be disclosed by the Scheme except in the circumstances set out in sections 76 and 79 of the ICNA Act. All information provided to the Scheme will be used only for the purposes for which it was provided under the ICNA Act.
