Phthalates are mainly used in material PVC. What phthalates / adipates or other plasticizers can be found in PET or polycarbonate? Which of them can migrate in mineral water?
Surely there will be no adipate in PET. It only has polymerized Ethylene terephthalate. In fact because of this, PET is always recycled to get fibres with high elasticity to be used in making say fishing nets.
PET and polycarbonates do not usually contain plasticizers but other classes of compounds are of concern e.g. aldehydes and antimony in PET or BPA in polycarbonate. The literature on the subject is vast and thorough.
PET & polycarbonates do not usually contain phthalates or adipates or other plasticizers. Besides HDPE, PET & polycarbonates (with minimum amounts of additives for coloring mainly) are widely used for bottles containing mineral water.
There has been no scientific evidence that there is migration of chemicals from the plastic bottle to the water even by changing the temperature up or down. PET & polycarbonate usually do not contain UV stabilizers. Scientists were afraid that the polycarbonate may have traces of bisphenol A "BPA" which has not reacted during the formation of the polycarbonate but studies over ~50 years indicated that BPA is not found & is removed during the polymer processing.
Therefore, PET & polycarbonate are safe to use in a reasonable manner & there is no need for fear.
