Alexium International : Alexiflam® NF Granted EPA Approval, Supporting US-Based Sales

Perth, Australia, and Greer, South Carolina- 30 April 2019- Alexium International Group Limited ('Alexium,' 'the Company,' ASX: AJX, NASDAQ Designation: AXXIY) is pleased to announce that it has received US Environmental Protection Agency (EPA) approval under TSCA for the manufacture and sale of Alexiflam® NF in the US. The EPA approval provides Alexium with access to the largest market region for flame retardant cotton and follows the recent announcement of the Company's Memorandum of Understanding with ICL (TASE/NYSE: ICL) for the future manufacture, marketing and sales of Alexiflam® NF.

Alexiflam® NF is a patent pending flame retardant developed by Alexium for the treatment of cotton and cellulose-based textiles. Alexiflam® NF has enhanced flame-retardant properties over incumbent products. In addition, it provides improved environmental and health profiles:

• Essentially formaldehyde free
• Mild application conditions
• Ammoniation free application.

The approval received under the US Toxic Substances Control Act (TSCA) follows the successful completion of the EPA's risk assessment of the hazards associated with the manufacturing, processing, and use of Alexiflam® NF. TSCA regulates the introduction of new chemical products in the US. Recently updated by the Lautenberg Chemical Safety Act, the assessment of Alexiflam® NF was under the more rigorous new TSCA standard.

This EPA approval provides Alexium with the ability to manufacture and sell Alexiflam® NF in the US, which represents nearly half of the global flame-retardant cotton market. Based on the provisions of the approval, Alexium can produce the volumes of Alexiflam® NF needed to support the Company's sales targets for military and industrial application in the US.

Commenting on the EPA's approval of Alexiflam NF®, Alexium CEO Dr. Bob Brookins said: 'EPA approval of Alexiflam® NF marks a significant milestone for the Company. This approval supports Alexium's manufacture and sales into the US, which represents the largest global market for flame retardant cotton products. The EPA approval builds on our recent MoU with ICL for them to act as the future manufacturer and distributor of Alexiflam® NF. Having delivered on these milestones, Alexium is well placed to drive the commercialization of Alexiflam® NF and deliver on the global opportunities we see for our unique textile technology.'
