Thai FDA Published the list of Forbidden Cosmetic Ingredients
The Thai Food and Drug Administration (Thai FDA) has officially updated the list of prohibited ingredients for cosmetic products. This announcement, issued by the Ministry of Public Health, introduces new restrictions to ensure consumer safety and compliance with regulatory standards.
Key Updates on Forbidden Cosmetic Ingredients
Effective immediately, a total of 56 new substances have been added to the list of ingredients prohibited in cosmetic manufacturing. This decision follows recommendations made during the 4th meeting of the Cosmetic Committee on August 26, 2024. Manufacturers, importers, and distributors must comply with the new regulations within 180 days from the effective date.
Implications for Cosmetic Businesses
Businesses involved in cosmetic production and distribution must take immediate action to verify that their products do not contain any of the newly banned substances. Non-compliance could result in penalties, product recalls, or legal action. Companies should review their ingredient lists, update formulations, and coordinate with regulatory consultants to ensure adherence to Thai FDA guidelines.
