13 PFASs will no longer be allowed in cosmetics in Thailand.

On 12 March 2023 Thailand's Food and Drug Administration (FDA) has announced plans to outlaw the use of 13 per- and polyfluoroalkyl substances (PFASs) despite the fact that none of the 13 substances are currently used in cosmetics products in Thailand.

The FDA proclaimed in a draft gazette notification (B.E. 2566–2023) that the country's Cosmetics Committee had authorised the intervention. The FDA asserted that after gazing over cosmetics that that had been registered as being manufactured and imported for sale in Thailand, it unearthed and none of them contained the components noted below. Before releasing a final version, the Authority needs authorization from the Minister of Public Health.

The 13 per- and polyfluoroalkyl substances listed in the draft are:

1. Perfluorooctane sulfonate (PFOS)

2. Potassium perfluorooctanesulfonate (potassium heptadecafluorooctane-1 -sulfonate)

3. Diethanolamine perfluorooctane sulfonate

4. ammonium perfluorooctane sulfonate (ammonium heptadecafluorooctanesulfonate)

5. Lithium perfluorooctane sulfonate (lithium heptadecafluorooctanesulfonate)

6. Perfluorooctanoic acid (PFOA)

7. Ammonium pentadecafluorooctanoate

8. Nonadecafluorodecanoic acid

9. Ammonium nonadecafluorodecanoate

10. Sodium nonadecafluorodecanoate

11. Perfluorononanoic acid (PFNA)

12. Sodium heptadecafluorononanoate

13. Ammonium perfluorononanoate
