Chemical Information Call-in: Round One

carbon nanotubes

For the first call-in, DTSC requested information about carbon nanotubes (also known as “CNT”).  DTSC searched scientific literature and publicly available data sources, hosted a roundtable discussion, and participated in a webinar as part of the call-in process for obtaining information about carbon nanotubes.

DTSC sent a formal request letter on January 22, 2009, to 26 companies which were identified as producers or importers of carbon nanotubes in or to California.  The letter required manufacturers and importers to submit their responses within one year.  DTSC sent a follow-up letter on February 16, 2010, to remind companies that had not yet responded.  The Round One carbon nanotube responses were:
