On February 28, 2025, Thailand released nine draft announcements for public consultation, proposing significant amendments to the country's cosmetic ingredient lists. The revisions include the addition of 17 prohibited ingredients and 2 restricted ingredients, modifications to 4 existing ingredient entries, and the removal of 2 permitted preservatives. These changes align Thailand’s regulations with updates to the ASEAN Cosmetic Directive adopted at past ASEAN Cosmetic Scientific Body (ACSB) meetings.
The consultation period will end on March 14, 2025, and stakeholders are encouraged to submit feedback before that. Once finalized, most amendments will take effect from the day following their publication in the Government Gazette, while a few changes will be implemented after a 180-day transition period.
Below are the details of the key proposed amendments (the text in red indicates changes to the previous lists):
1. List of Prohibited Ingredients: One Revision and 17 Additions
The draft proposes modifying the existing prohibition on Barium Salts and adding 17 new prohibited ingredients (entries 1669–1685), which have been identified as CMR (Carcinogenic, Mutagenic, or Reproductive toxic) substances.
With the exception of entries 1676–1685, which will take effect 180 days after publication, all other changes will be enforced on the day following publication in the Government Gazette.

2. List of Restricted Ingredients: One Revision and Two Additions
The proposed amendments include an update to the specifications of Hydrogen Peroxide and the addition of two new restricted ingredients: Silver Zinc Zeolite (entry 213) and Methyl-N-methylanthranilate (Dimethyl anthranilate, etc.) (entry 214).
Once approved, entries 213 and 214 will take effect from the day following their publication in the Government Gazette, while the revisions to Hydrogen Peroxide will be enforced 180 days after publication. Cosmetic products containing entry 214 that were notified before the final announcement takes effect must comply with the new requirements within 180 days.

Special Provisions for Dental Bleaching Products Containing Hydrogen Peroxide
A separate announcement introduces additional requirements for professional-use dental bleaching products containing Hydrogen Peroxide. According to the draft, "dental bleaching products for dentists containing Hydrogen Peroxide" refers to products dispensed to consumers for home use by dental professionals.
Once the regulation takes effect 180 days after publication, notifiers of such products must indicate the concentration of Hydrogen Peroxide on the product label.
3. List of Permitted Preservatives: Two Deletions and One Revision
The draft proposes removing two existing preservatives (entries 37 and 38) and modifying the usage conditions for Sodium Hydroxymethylglycinate (entry 48).
These changes will take effect from the day following their publication in the Government Gazette. To facilitate a smooth transition, a 180-day grace period will be granted to cosmetic businesses that have already received notification receipts for products containing the affected preservatives before the regulation takes effect.

In accordance with the updated permitted preservative list, the removal of entries 37 and 38 will also be reflected in the List of Warnings on Labels of Cosmetics Containing Permitted Preservatives.
4. List of Permitted Sunscreens: One Revision
The draft proposes modifying the use limits and usage conditions of the existing sunscreen agent Octocrylene.
Once enacted, these changes will be effective from the day following their publication in the Government Gazette. However, cosmetic businesses whose products containing Octocrylene that were notified before the finalized regulation takes effect will have a 180-day transition period to allow for compliance adjustments.
