SI Group is pleased to announce that the US Food & Drug Administration (FDA) has granted Food Contact Notification (FCN) 2326 for phosphite antioxidants WESTON™ 705 and WESTON™ 705T. The FCN extends the use of these phosphite antioxidants to PET polymers.

WESTON™ 705 and WESTON™ 705T are nonylphenol-free stabilizers that already have broad approval as Food Contact Substances for use in various polymers for food-contact packaging around the globe, including the United States, Canada, the European Union, and China. This latest grant permits the use of WESTON 705 and WESTON 705T in PET polymers and they may be used at levels not to exceed 2000 parts per million (ppm) under conditions of use A (> 212 deg.F) through H (frozen).

“SI Group is committed to investing in and providing antioxidants that meet the current safety needs of consumers globally,” says Robert Kaiser, VP Polymer Solutions & Managing Director EMEA. “With this latest approval extension from the FDA, WESTON™ 705 and WESTON™ 705T demonstrate safety profiles that align with the current requirements of responsible PET food packaging producers and brand owners.”

The approval went into effect on March 1, 2024.
