Antimony is present in bottled waters because used as a catalyst in PET production.
Manufacturers frequently use antimony trioxide (Sb2O3), antimony acetate, and antimony glycolate as catalysts in PET resin production. Consequently, antimony remains in the finished products. Researchers need to conduct additional studies to determine if Antimony in PET can be an endocrine disruptor.

Researchers from the University of Geneva reviewed over 192 scientific articles studying antimony in PET bottles. They identified several analytical issues in experimental design and common flaws included whether the limit of detection (LOD) of the analytical technique matched the analyte concentration. Additionally, researchers often did not use Certified Reference Materials (CRMs) with concentrations similar to the analyte.
Furthermore, almost none of the studies provided information on antimony concentration in water before bottling. Researchers often reported analyte concentration per volume, but the authors recommend reporting based on bottle surface area.
Despite these methodological issues, several widely proven facts exist regarding PET and antimony presence:
