ADDIVANT™ RECEIVES FURTHER FDA APPROVALS FOR THE USE OF ITS NEXT GENERATION WESTON® 705 LIQUID PHOSPHITE ANTIOXIDANT FOR FOOD CONTACT APPLICATIONS

Danbury, Conn (July 1, 2015) - Addivant™, a global leader in polymer additive technologies, today announced that its WESTON® 705 phosphite antioxidant for use in polymers, has received additional food contact clearance from the U.S. Food and Drug Administration (FDA). This enhanced clearance increases the limits of WESTON® 705 phosphite antioxidant that can be used in high density polyethylene (HDPE) from 1500ppm to 2000ppm and removes the limitation on contact with high alcohol food types.  

Addivant™ produces its liquid phosphite antioxidants in multiple facilities worldwide ensuring security of supply for customers around the globe. 

“This is another very important milestone in the commercialization of WESTON® 705 phosphite antioxidant. The FDA’s additional endorsement of WESTON® 705 will accelerate the replacement of the old Tris(nonylphenyl) phosphite (TNPP) and Tris(2,4-ditert-butylphenyl)phosphite (AO-168 type) antioxidants both of which are today facing increasing regulatory scrutiny,” said Peter Smith, President Commercial Operations.  “Today, several of the world’s largest polymer producers are switching to WESTON® 705 recognizing the benefit of its superior polymer performance, higher processing productivity and of course its clean toxicological profile.”
