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:
Perfluorooctane sulfonate (PFOS)
Potassium perfluorooctanesulfonate (potassium heptadecafluorooctane-1 -sulfonate)
Diethanolamine perfluorooctane sulfonate
ammonium perfluorooctane sulfonate (ammonium heptadecafluorooctanesulfonate)
Lithium perfluorooctane sulfonate (lithium heptadecafluorooctanesulfonate)
Perfluorooctanoic acid (PFOA)
Ammonium pentadecafluorooctanoate
Nonadecafluorodecanoic acid
Ammonium nonadecafluorodecanoate
Sodium nonadecafluorodecanoate
Perfluorononanoic acid (PFNA)
Sodium heptadecafluorononanoate
Ammonium perfluorononanoate

As required under the Hazardous Substance Act B.E. 2535 (1992), the Ministry of Industry of Thailand's Department of Industrial Works opened the first draft notification for the public hearing procedure on 20 May 2021. It has perfluorooctanoic acid (PFOA) included as part of the primary revision. On 3 May 2019, more than 180 nations decided to prohibit the manufacturing and use of PFOA, its salts, and PFOA-related chemicals at the international Stockholm Convention on Persistent Organic Pollutants (POPs)
However, as unintended trace contamination is possible, to calculate this the Department of Industrial Works evaluates European Union Regulation (1019/1021)
The draft specifies the following exemptions under Type 4 (banned chemicals):
Substance name |
Hazard classification |
Exemption |
Perfluorooctanoic acid CAS No. 335-67-1 |
PFOA and its salts classified as Type 4 hazardous substances (banned for production, import, export, or possession) |
The following applications will be permitted as Type 3 substances; Photolithography or etch processes in semiconductor manufacturing Photographic coatings applied to films Textiles for oil and water repellency for the protection of workers from dangerous liquids that comprise risks to their health and safety Fire-fighting foam for liquid fuel vapor suppression and liquid fuel fires (Class B fires) Manufacture of polytetrafluoroethylene (PTFE) and polyvinylidene fluoride (PVDF) for the production of: Industrial waste heat exchanger equipment Industrial sealants capable of preventing leakage of volatile organic compounds and PM2.5 particulates Manufacture of polyfluoroethylene propylene (FEP) for the production of high-voltage electrical wire and cables for power transmission Manufacture of fluoroelastomers for the production of O-rings, v-belts, and plastic accessories for car interiors

In the manufacturing of fluoropolymers, PFOA (a synthetic perfluorochemical) is produced as a byproduct. A class of substances known as perfluorochemicals (PFCs) is used to create fluoropolymer coatings and goods that withstand heat, oil, stains, grease, and water. For instance, PFOA was used in the manufacture of polytetrafluoroethylene (PFTE) better known as Teflon. People are most likely exposed to PFOA through the consumption of tainted water and perhaps through the use of PFOA-containing items. Compared to the general population, perfluorochemical industry workers may be exposed to higher levels of PFOA.
Other PFOA-related chemicals on Thailand's List No. 5.1(Hazardous Substance Act's Annex 5) now have different classifications: Substances 523-533 are now Type 3 hazardous substances when certain conditions or exemptions apply, while Substances 534-541 are now Type 4 hazardous substances when such conditions or exemptions are not present, such as when the concentration is below 0.0000025% w/w. Industrial chemicals, chemical waste, discarded electrical and electronic equipment, and chemical weapons convention chemicals are all regulated by Annex 5.
In addition, the first draft notification has two additional compounds with more accurate classifications:
The classification of benzyl cyanide (Cas RN 140-29-4) has been changed from Type 1 (hazardous substance) to Type 3. Triethanolamine (Cas RN 102-71-6), which is already a Type 3 substance, has also had a threshold limit of > 30% w/w applied in accordance with list 3B (precursors) annexed to the Chemical Weapons Convention.
