Food-contact clearance was recently received by three companies of additives while a fourth received the green light for environmentally-friendly registration.

Dover Chemical, Dover, Ohio, now has FDA clearance for its proprietary high-molecular-weight Doverphos LGP-11 phosphite antioxidant as a thermal stabilizer in single- and repeated-use LLDPE films and HDPE articles in contact with all food types under Conditions of Use A through H, at loading levels in polymer up to 2000ppm. 

Addivant, Danbury, Conn., has received additional FDA food contact clearance for its Weston 705 phosphite antioxidant. The enhanced clearance increases the limits of this antioxidant that can be used in HDPE from 1500ppm to 2000ppm and removes the limitation on contact with high-alcohol food types. 

Trinseo, Berwyn, Penn., got FDA’s green light on several grades of Magnum ABS resins (3453, 3904/3904 Smooth, and 8391/8391 MED resins) as food-contact compliant. This allows their use in kitchen appliances, kitchenware, food packaging, as well as medical devices. 

Akcros Chemicals, New Brunswick, N.J., has confirmed several new registrations for its ‘environmentally-friendly’ Intercide isothiazolone-based solid and liquid biocides in Canada and expected new carrier registrations in the U.S. In 2013,  Akcros & Dow Microbial Control extended their strategic releationship for biocides for plastics on a global basis. Under the agreement, Dow Microbial Control transferred manufacturing equipment and provided Akcros with additional expertise to manufacture an enhanced line of isothiazolone-based solid carriers for protection of plastics.
