I'm thinking of submitting for this pilot credit with one of my products being a type 6,6 Interface carpet tile (Tectonics). Pharos tells me that it contains PET- Polyethylene Terephthalate, which is a phthalate. However, it is not listed in Tom Lent's CASRN List for Pilot 11. Is PET a chemical to avoid under this credit?

After doing some research, I believe the answer to this question is the following:
Orthophthalates are often added to plastics to make them soft and flexible (i.e., they are plasticizers). These orthophthalates are the ones denoted by the word "phthalate," and they are the ones most associated with health concerns. PET is made from terephthalic acid, which is chemically different from orthophthalic acid. This page from the NIH website helps clarify: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1367856/
