Rochester Hills, Michigan – CertiPUR-US is to add another substance to the list of prohibited substances in the foam it certifies. The new chemical on the list is stannous octoate (tin (II) 2-ethylhexanoate), a catalyst used to produce flexible PU foam. The ban comes into effect on 23 November 2023.
Its addition to the list comes after the European Commission reclassified 2-ethylhexanoic acid, and most of its salts, as a reprotoxic 1B substance. This comes with a hazard statement that it may damage the unborn child.
The advance notice of the ban gives industry time to reformulate its foams, which may require significant process changes. The renewal date for an individual foam’s certification means some producers will have to make the transition in 12 months, while others may have a little more time.
‘Substances which are classified as “may cause cancer”, “may cause genetic defects” or “may damage fertility or the unborn child” are prohibited in CertiPUR-US certified foam,’ said Michael Crowell, the organisation’s executive director.
CertiPUR-US certified foams are used to produce cushioning in home furnishings such as mattresses, pillows and upholstered furniture. More than 90 manufacturers of flexible PU foam in 18 countries currently certify more than 200 different foam formulations through the programme.
The certification criteria were established in 2008, and based on data from the EU’s Reach programme and from other chemical regulatory bodies. This was done with guidance from chemists, environmental scientists and toxicologists, in conjunction with leaders from the foam, mattress and upholstered furniture industries.
This is not the first time the that the technical guidelines for certification have been updated. ‘Vigilant monitoring of chemical assessments and transparency are essential to earning and maintaining consumer confidence in the integrity of the CertiPUR-US program,’ Crowell said.certification criteria have been updated.
