Sadly I found a study at https://pmc.ncbi.nlm.nih.gov/articles/PMC3222987/ https://pmc.ncbi.nlm.nih.gov/articles/PMC3222987/ saying that many polypropylene polyethylene products release estrogenic chemicals (IDK if it's the same as phthalate) likely from additives, including when bent/deformed. And polycarbonates are infamously made of polymerized BPA and similar chemicals (usually endocrine disruptors).
- arcticbull 2y agoThanks for sharing the study. I will say the made-from argument is less compelling since table salt is made from sodium (explosive) and chlorine (chemical warfare agent) and yet it's pretty yummy. So long as it doesn't degrade, that's not super problematic. However the study I will read.
- nyanpasu64 2y agoPolycarbonates have been known to leach from BPA (https://www.hsph.harvard.edu/news/press-releases/bpa-chemical-plastics-leach-polycarbonate-drinking-bottles-humans/ https://www.hsph.harvard.edu/news/press-releases/bpa-chemica...), I don't know if they've tightened up manufacturing or switched to non-estrogenic or non-bioactive chemicals since then.
- arcticbull 2y agoJust following up! Yeah that's really interesting, I read both of your links. Again thank you for sharing. To be clear my reaction was just to the "made of scary components" thing, I was not dismissing your suggestion that harmful chemicals may leach from the final product.
