The latest bill in the United States: 5 chemical substances will no longer be used in food packaging



The latest bill in the United States: PFAS, phthalates, bisphenol, styrene, and antimony trioxide will no longer be used in food packaging

Recently, Democratic lawmakers in the United States proposed legislation to list PFAS, phthalates, bisphenols, styrene, and antimony trioxide as substances unsuitable for use in food contact.

As more and more states have established their own food safety regulations, the House of Representatives has decided to introduce the Food Packaging Non Toxic Substances Act on October 26th, aimed at federally prohibiting the use of these compounds in food contact materials (FCMs). It is worth mentioning that this bill also overlaps with the restrictions in the earlier US Plastic Act. In the latest bill, after several rounds of intense debate, it was ultimately decided in the Federal Food, Drug, and Cosmetic Act to designate the following unsafe substances as not suitable for contact with food, which will take effect two years later:

  • Any chemical belonging to the phthalate class

CAS number

Substance name


Phthalic acid dicarboxylic acid( α- Ethylhexyl ester)


Benzyl butyl phthalate


Dibutyl phthalate


Diisodecyl phthalate


Dihexyl phthalate


Diisononyl phthalate


Dioctyl phthalate


Diethyl phthalate


Diisobutyl phthalate


Dipentyl phthalate


Dipentyl phthalate
  • PFAS is defined as "a perfluoroalkyl substance with at least one perfluorocarbon atom or an artificial perfluoroalkyl substance".
  • Bisphenol A, B, S, F or AF or "related compounds".
  • Styrene is an important organic compound in industry, including synthetic resins, ion exchange resins, and synthetic rubber.
  • Antimony trioxide, which can extinguish flames, is often used as a fireproof coating in daily life. But it is classified as a Category 2B carcinogen by the International Agency for Research on Cancer (IARC).



In daily life, thousands of synthetic chemicals are used to manufacture materials in contact with food. The above-mentioned chemicals have been confirmed by scientific research to increase the risk of allergic reactions and breast cancer. Given the increasing scientific evidence revealing the urgency of this issue, researchers and health practitioners are vigilant about the issue of toxic chemicals in food packaging.
