Dover Chemical Corporation receives FDA expanded-use clearance

Published: March 10, 2017 10:00 AM

Dover Chemical Corporation has received expanded-use FDA clearance for Doverphos LGP-11 antioxidant as a thermal stabilizer in polypropylene (PP) and high impact polystyrene (HIPS), used as components of finished food packaging and repeated-use articles in contact with all types of food under Conditions of Use A through H, at loading levels in polymer up to 2000 ppm.

This expanded food contact clearance is in addition to the existing clearance for Doverphos LGP-11 antioxidant as a thermal stabilizer in single- and repeated-use linear low density polyethylene (LLDPE) films and high density polyethylene (HDPE) articles in contact with all food types under Conditions of Use A through H, at loading levels in polymer up to 2000 ppm. Additional clearances also include use in adhesives and pressure-sensitive adhesive applications complying with 21 CFR 175.105 and 21 CFR 175.125, respectively, can-end cements complying with 21 CFR 175.300(b)(3)(xxxi), and repeated-use food-contact articles, at loading levels in polymer up to 1 percent.

Doverphos LGP-11 is a proprietary polymeric liquid, high molecular weight phosphite that is suitable as an alternative to TNPP, or any other phosphite additive in any polyolefin application. Doverphos LGP-11 is also recommended for use in other resin systems such as SBS, SBR, urethanes and PVC. Doverphos LGP-11 is unique in that it contains no alkylphenol components, has superior color hold, has low migration due to its polymeric nature, and is composed of biodegradable raw materials.

"The fact that LGP-11 is not produced from alkylphenols provides benefits that are unprecedented by other phosphites on the market today," noted Dr. Mick Jakupca, Director of Research and Development at Dover Chemical Corporation. "Most antioxidants are composed of or contain alkylphenols. Alkylphenols, as a general class of chemicals, are a focus of both consumer and regulatory organizations. Doverphos LGP-11 was engineered to offer the global plastics market a viable long-term alkylphenol-free alternative chemistry.

"Dover Chemical Corporation has a long history of developing truly novel products and processes that address the concerns of our customers and consumers. The polymeric nature of this product has routinely demonstrated the reduction and/or elimination of plate-out and blooming of the antioxidant in blown and cast film applications, which has been an industry-wide problem for decades."

Matthew Fender, Business Manager of Polymer Additives, added: "Doverphos LGP-11 was designed to meet long-term global market needs, and receiving additional food contact clearances by the US FDA is certainly an important milestone for all of us and for our customers. The additional food contact clearance for both PP and HIPS applications will certainly allow our customer base to proceed with planned commercial-scale evaluations."
