FCN No. 64

Return to Listing
Food Contact Substance:  Diallyldimethylammonium chloride polymer with acrylamide (CAS Reg. No. 26590-05-6). The copolymers are produced by copolymerizing diallyldimethylammonium chloride with acrylamide in weight ratios ranging from 85/15 to up to but not including 50/50 diallyldimethylammonium chloride/acrylamide.
Notifier:  Nalco Chemical Company
Manufacturer:  Nalco Chemical Company
Intended Use:  For use only as a drainage and/or retention aid employed prior to the sheet-forming operation in the manufacture of food-contact paper and paperboard.
Effective Date:  07/27/2000
Limitations/Specifications:  The finished resins in a 1 percent by weight aqueous solution (active polymer) have a viscosity of 10 centipoises or more at 22°C (72°F) as determined by an LVF-series Brookfield Viscometer using a No. 2 spindle at 60 rpm (or by other equivalent methods). For use at a level not to exceed 0.05 percent by weight of the finished paper and paperboard.
