Reassessment of benzyl alkonium chlorides

Submissions on our proposed updates to the benzyl alkonium chloride (BAC) approvals are now open.

BACs are a family of surfactants which have diverse uses, including in detergents, pesticides, veterinary medicines, timber treatments, and disinfectants.

We have reviewed the hazard classifications of BACs and substances that contain BACs, and have proposed revised hazard classifications for these substances. The revisions to these hazard classifications have been informed by regulatory reviews and databases from overseas jurisdictions.

We are processing this application as a modified reassessment, so only specific aspects of the approvals will be considered during the reassessment. The approvals cannot be revoked in this process.

Suppliers, manufacturers, and users of chemical products should read the application documents to see whether their products are affected by the proposed changes.

You can make a submission on our proposals and let us know if you have relevant information about any specific substances.

Submissions close at 5pm on 27 February 2020.

Background to the reassessment of BACs

Grounds for reassessment of BACs were established on 30 July 2019. They were decided by a Decision-making Committee, based on the availability of significant new information relating to the effects of the substances.
