Caught over at "In the Pipeline" a report on how phthalates are naturally occuring substances, bis(2-ethylhexyl) phthalate no less. Look at the abstract! And all this time everyone has been picking on PVC and every plasticizer that has ever been added to it. Now it can be claimed as being an all natural, green substance that has just been misunderstood. What wonderful news for the polymer industry.
Undoubtedly the chemical is a contaminant that wasn't identified because a control wasn't run.
