Polyethylene Terephthalate May Yield Endocrine Disruptors
".... Discussion: The available research suggests that the concentration of phthalates in the contents of PET bottles varies as a function of the contents of the bottle, with phthalates leaching into lower pH products such as soda and vinegar more readily than into bottled water. Temperature also appears to influence the leaching both of phthalates and of antimony from PET, with greater leaching at higher temperatures...."
Upshot: yes on leaching at higher temperatures, probable yes on acidic products also triggering leaching.
