Regulatory and Sustainability Initiatives Lead to Improved Polyaminopolyamide-epichlorohydrin (PAE) Wet Strength Resins and Paper Products, 18PaperCon

Polyaminopolyamide-epichlorohydrin (PAE) resins are the predominant commercial products used to manufacture wet strengthened paper products. Since their development in the late 1950s, the first generation (G1) resins have proven to be one of the most cost effective technologies available to provide wet strength to paper.  Throughout the last three decades, regulatory directives and sustainability initiatives from various organizations have driven the development of “cleaner” and safer PAE resins and paper products.

Early efforts in this area focused on improving worker safety and reducing the impact of PAE resins on the environment.  These efforts led to the development of resins containing significantly reduced levels of 1,3-dichloro-2-propanol (1,3-DCP) and 3-monochloropropane-1,2-diol (3-MCPD), potentially carcinogenic by-products formed during the manufacturing process of PAE resins.  As the levels of these by-products decreased, the environmental, health and safety (EH&S) profile of PAE resins and paper products improved.  Recent initiatives from major retailers are focusing on product ingredient transparency and quality, thus encouraging the development of safer product formulations while maintaining performance.
