As stipulated by the Cosmetic Hygiene and Safety Act, cosmetic enterprises shall prepare and maintain a Product Information File (PIF) for cosmetics, which contains scientific and complete files on product's safety and function. In March 2020, Taiwan Food and Drug Administration (TFDA) promulgated the Guidelines on the Establishment of PIF to guide enterprises on how to compile the PIF. To ensure its applicability to enterprises' practical need, TFDA updated the Guidelines on July 28, 2022, which entered into force upon its release.
