July 14, 2014 – Bethesda, MD – 
Questioning the California Department of Toxic Substances Control’s (DTSC) choice of polyurethane spray foam (SPF) as Priority Product to undergo alternative formula  analysis, the Adhesive and Sealant Council (ASC) urged the Department to reconsider its selection while making the process for future product selections more transparent.  The comments were part of a written submission provided by ASC to the Department regarding the state’s new Safer Consumer Products regulation on June 30.

“The Council and our members were extremely surprised by this initial product choice,” said ASC’s Director of Regulatory Affairs, Mark Collatz.  “It became even more shocking when the Department’s own Priority Product profile for SPF contained so many misstatements and inaccuracies.”

The Council’s written comments also suggested that in the future the Department consider establishing an external advisory committee, made up of experts, familiar with the products under review, to evaluate materials to be published before they are made public.

Mr. Collatz pointed out the biggest series of misstatements in the document were the continuous references to the presence of toluene disisocyanate (TDI) and hexamethylene diisocyanate (HDI) in SPF products.  He noted that subsequently, numerous sources have detailed that only methylene diphenyl diisocyanate (MDI) and it oligomers are in SPF systems.  Yet the DTSC, while acknowledging the mistake, failed to revise the original document or remove it from their website.

“Without the elimination of these erroneous references from the DTSC document, any misinformed person or organization who has visited their website can mischaracterize these products,” said Collatz.

He also noted that the Department has defined the entire product category in such a way as to lump together multiple chemistries and different application systems.  As a specific example, he pointed out that in their product category descriptions, the Department combines spray foam systems with one component foam (OCF) systems.

“Clearly these OCF products with a ‘beaded foam’ application do not offer the same airborne exposures as SPF products.  Nowhere in the DTSC document is that explained or reconciled,” said Collatz.
