Document Summary

Claire nelson, arkansas high school student who learned that a plasticizer called deha (di(ethylhexyl)adipate) is found in plastic wrap and that the fda had never investigated whether or not the. She did an experiment where she heated up plastic wrap and olive oil and measured deha levels higher than the 0. 05 bbp that the fda recommends as the max. However, this actually had been investigated before (they did have a maximum recommended amount after all). Also, her experiment was not realistic; those are the conditions that maximize leaching. The concern is that some plasticizers, such as dhep (di(ethylhexyl)phthalate) may have estrogen-like properties, which can be linked in theory to certain cancers. But deha (used in pvc wrap) does not fall into this category: both the eu and the environmental protection agency in the us have both classified it as not a suspected carcinogen , also, only pvc wraps contain deha. They are also likely not that wraps that people purchase.
