On May 27, 2026, the Australian Industrial Chemicals Introduction Scheme (AICIS) announced the addition of the industrial chemical 1,3-Propanediamine, N-[3-(C11-14-isoalkyloxy)propyl] derivs., C13-rich, acetates (CAS No. 151789-08-1) to the Australian Inventory of Industrial Chemicals (Inventory). The listing took effect on May 26, 2026, in accordance with Section 82 of the Industrial Chemicals Act 2019, which provides for chemicals to be added to the Inventory five years after the issuance of an assessment certificate. The chemical was previously assessed for importation at volumes of up to 200 tonnes per year, with no reformulation or repackaging activities occurring in Australia. Its approved use is limited to industrial mining facilities, where it serves as a flotation agent at concentrations of up to 5% and is handled exclusively by workers. Following the completion of the five-year post-assessment period, the chemical has now been formally included in the national Inventory. The update reflects Australia's regulatory process for transitioning assessed industrial chemicals into the Australian Inventory of Industrial Chemicals after the prescribed monitoring period under the Industrial Chemicals Act 2019.
