Addivant has received final approval for its ‘blockbuster additive’ WESTON 705, the first antioxidant since the 1970s that has achieved global food-contact approvals.

The next generation nonylphenol-free liquid phosphite antioxidant for plastics and elastomers can be used in water bottles, dairy milk bottles and packaging for snacks, among others.

Food-contact packaging

It is already approved for use in food-contact packaging in more than 180 countries including the US, Canada, Europe and China. 

With this latest approval, it has completed its global food-contact approval process, which means resin producers and packaging manufacturers can ‘stay ahead of the regulatory curve’. 

“This final approval is a critical step for Addivant’s blockbuster additive which will allow us to accelerate the transformation of our company and fuel further investments in breakthrough innovation,​” said John Steitz, CEO, Addivant. 

Addivant is a supplier of liquid phosphite antioxidants for plastics. It claims ‘compared to benchmark phosphite antioxidants, WESTON 705 has up to 20% higher content of phosphorus and more reactive structures to decompose peroxide species formed during melt processing.’

WESTON 705 has now been included in the revision to the food contact regulation in the MERCOSUR region (Southern Common Market including Argentina, Brazil, Paraguay and Uruguay) for the use of WESTON 705 in broad food-contact packaging materials.
